Climate Change Litigation: A Growing Phenomenon
Summary
The scientific, economic, and political questions surrounding climate change
have long been with us. This report focuses instead on a relative newcomer: the legal
debate. Though the first court decision related to climate change appeared 18 years
ago, such litigation has proliferated in just the past five.
The court cases, decided and pending, arise in seven contexts. The first is the
Clean Air Act (CAA). In April, 2007, the Supreme Court held in Massachusetts v.
EPA that at least as to mobile sources of emissions (cars, trucks), EPA has authority
under the CAA to regulate greenhouse gas (GHG) emissions. This decision puts
pressure on EPA to move forward as well with regulation of GHGs from stationary
sources (powerplants, factories).
Second, litigation under the Marine Mammal Protection Act, and current and
likely litigation under the Endangered Species Act, raise the possibility that the
impacts of climate change on wildlife may constrain government and private
activities associated with GHG emissions.
Third, what about federal energy statutes? A much-publicized decision held that
under the Energy Policy and Conservation Act, the United States must monetize the
benefits of reduced carbon emissions as part of setting light-truck fuel economy
standards. The Outer Continental Shelf Lands Act also has been invoked.
Fourth, various statutes requiring federal government analysis and information
dissemination — the National Environmental Policy Act (NEPA), Global Change
Research Act, and Freedom of Information Act — have generated climate-change
litigation. NEPA suits make up the most numerous category of climate-change
litigation. Courts appear to agree that if a plaintiff can establish standing, NEPA can
be used to compel agency consideration of the climate change effects of its actions.
Fifth, can common law tort theories such as nuisance be used to force cutbacks
in GHG emissions, or payment of damages? All four decisions thus far have denied
relief to plaintiffs on lack of standing or political question grounds.
Sixth are the suits challenging state regulation of GHG emissions from motor
vehicles as preempted by the federal corporate average fuel economy standards or
federal authority over foreign policy. The two rulings thus far have rejected these
challenges. Moreover, these issues will be moot unless EPA’s denial of California’s
request for a waiver of federal preemption under the CAA is overturned in court.
Seventh, chiefly with respect to coal-fired power plants, what role will be played
by state utilities laws?
Finally, the report discusses international law aspects of a nation’s contributions
to climate change, and the few international claims made against the United States
to date.

Climate Change Litigation:
A Growing Phenomenon
Introduction
The scientific, economic, and political questions surrounding climate change
have long been with us. This report focuses instead on a relative newcomer: the legal
debate. Though the first court decision related to climate change appeared 18 years
ago, the quantity of such litigation has mushroomed in recent years: more than two
dozen cases pursuing multiple legal theories are now pending.
The principal court cases, decided and pending, arise in seven contexts — a
number that continues to rise. The first and most important context is the Clean Air
Act (CAA). In April, 2007, the Supreme Court held in Massachusetts v. EPA that
at least as to mobile sources of emissions (cars, trucks), EPA has authority under the1
CAA to regulate greenhouse gas (GHG) emissions.
Second, must global warming effects be considered under the federal wildlife
protection statutes, such as the Marine Mammal Protection Act and Endangered
Species Act? Third, must they be considered under federal energy statutes, such as
the Energy Policy and Conservation Act and Outer Continental Shelf Lands Act?
Fourth, may any of several information statutes, particularly the National
Environmental Policy Act, be used to compel government analysis of and
dissemination of information about climate change? Fifth, can common law tort
theories such as nuisance be used by state and private plaintiffs to force cutbacks in
GHG emissions, or payment of damages? Sixth, granted that state regulation of
GHG emissions from motor vehicles is preempted by the CAA (absent an EPA
waiver), is such regulation also preempted by other federal statutory or constitutional
law? And seventh, chiefly with respect to coal-fired power plants, what role will be
played by state utilities laws?
Sections I through VII of this report address these seven areas of litigation in
turn.2 Most known cases, decided and pending, are mentioned — omitted cases are

those that raise climate change issues in only the most marginal way or only
implicitly,3 and some state cases. Looking beyond the domestic lawsuits, Section
VIII surveys international-law arguments that might be used to induce GHG emission
reductions from the United States and other countries that are major GHG emitters,
and the few international-law claims filed against the United States to date. Finally,
Section IX offers overall comments.
I. Clean Air Act
Stationary Sources of GHG Emissions
The First EPA General Counsel Memorandum.
Aware that prospects for Senate approval of the Kyoto Protocol were dubious,4
some Members of Congress became concerned in the late 1990s that the Clinton
Administration EPA might seek to regulate GHG emissions in the absence of
approval, under either of two claimed authorities. One authority would derive from
an argument that even prior to ratification, the Protocol provided some sort of legal
basis for emissions restrictions, perhaps citing past treaties signed by the United5
States that were provisionally implemented prior to going into effect. This
possibility provoked a series of enactments barring EPA’s use of appropriated funds6
to implement the Kyoto Protocol in the absence of approval and ratification.


2 (...continued)
Broader treatments of the legal implications of climate change may be found in
Michael Gerrard (ed.), GLOBAL CLIMATE CHANGE AND U.S. LAW (ABA 2007), and
Symposium Issue, RESPONSES TO GLOBAL WARMING: THE LAW, ECONOMICS, AND SCIENCE
OF CLIMATE CHANGE, 155 U. Pa. L. Rev. 1353 et seq. (2007).
3 An example of a case that deals with climate change only implicitly (at least so far) is State
of New York v. U.S. Dep’t of Energy, No. 08- 0311 (2d Cir. filed January 17, 2008), in which
three states (NY, CN, MA) challenge the Department’s energy conservation standards for
residential furnaces and boilers. Though we are given to understand that the climate change
benefits of reducing fossil fuel consumption by such furnaces and boilers was a
consideration in filing suit, the petition for review does not mention CO2 or climate change,
and thus we do not include this case in the body of the report.

concluded December 10, 1997, U.N. Doc. FCC/CP/1997/L.7 Add. 1, reprinted at 37 I.L.M.

22 (1998). One indication of Senate antipathy to the Kyoto Protocol was its adoption by 95-


0 of the so-called Byrd-Hagel resolution urging the President not to sign any international
agreement on climate change that would result in serious injury to the U.S. economy or that
did not include provisions regarding the GHG emissions of developing countries. S. 98,th

(continued...)

The rest of this section deals with the second issue: EPA’s possible authority
to regulate GHG emissions independently of the Protocol, under the CAA. This
authority has now been confirmed by the Supreme Court, at least as to mobile
sources; nonetheless, this report retains from earlier versions some of the historical
evolution of the issue for the sake of a fuller appreciation of its complexity.
During hearings on EPA’s FY1999 appropriations, Representative Tom DeLay
asked then-EPA Administrator Carol Browner whether the EPA believed it had
authority under the CAA to regulate GHG emissions. This led, weeks later, to an
EPA General Counsel memorandum,7 which concluded that CO2 satisfies the CAA
definition of “air pollutant,” but that this is only the first step. Before EPA can
regulate CO2 emissions, it must further conclude that CO2 meets criteria in other
CAA provisions requiring the agency to determine that the substance poses harm to
public health, welfare, or the environment. This next step EPA declined to take.
At a House hearing in 1999,8 a panel of legal experts argued the question of
EPA’s authority to regulate CO2 under the CAA. A new EPA General Counsel
endorsed his predecessor’s analysis in the 1998 memorandum, but just as his
predecessor, stressed that the EPA’s legal analysis was “largely theoretical” since
“EPA currently has no plans to regulate carbon dioxide....”9 This hands-off position
was prompted in part by strong congressional opposition based on uncertainties as
to the economic impact of regulating a pollutant as widespread as CO2. In addition,
some in Congress argued that CAA implementation of a CO2 standard was barred by
the aforementioned enactments (appropriation riders) prohibiting implementation of
the Kyoto Protocol.10
The EPA General Counsel opinion that “air pollutant” includes GHGs held
sway until 2003, when that office reversed itself in the context of a petition asking
the agency to regulate GHG emissions from mobile sources. This story picks up
below (“Mobile Sources of GHG Emissions”).

Suits Enforcing the CAA Against EPA.
Two suits have been filed seeking to compel EPA to regulate GHG emissions
from stationary sources.
In Massachusetts v. Whitman, filed in 2003, three Northeast states (MA, CT,11
ME) sought to force EPA to list CO2 as a “criteria pollutant” under the CAA. They
argued that on various occasions, EPA had indicated its belief that CO2 emissions
contribute to climate change. These EPA statements constituted, in the words of
CAA section 108,12 a “judgment [that GHG emissions] cause or contribute to air
pollution which may reasonably be anticipated to endanger public health or welfare”
and, also per section 108, that such emissions “result[] from numerous or diverse
mobile or stationary sources.” These prerequisites being satisfied, the suit argued,
section 108 required EPA to add CO2 to its list of “criteria pollutants,” then proceed13
under section 109 to develop national ambient air quality standards for CO2. On
September 3, 2003, a few days after EPA’s denial of a petition asking the agency to
regulate GHG emissions from motor vehicles, the plaintiff states voluntarily
dismissed this suit without prejudice, reportedly so as to transfer their energies to a
suit challenging the petition denial (leading to the Supreme Court’s Massachusetts
v. EPA decision).
The second suit is New York v. EPA, which seeks to compel EPA to issue a New
Source Performance Standard (NSPS) for CO2. Unlike the first case, however, this
one will be litigated in the shadow of Massachusetts v. EPA, holding that EPA has
authority under the CAA to regulate GHGs from mobile sources. The burning
question is how this litigation seeking to compel EPA regulation of stationary-source
GHG emissions will be affected.
New York began with an EPA proposal to revise its NSPSs for electric utility
and other steam-generating units. Some commenters on the proposed rule argued
that EPA must, in addition to the revisions proposed, set NSPSs for GHGs emitted
from steam generating units. The commenters pointed to CAA section 111’s
command that EPA promulgate NSPSs to address emissions from new stationary
sources that “cause[], or contribute[] significantly to, air pollution which may
reasonably be anticipated to endanger public health or welfare.” In promulgating its
final rule in February, 2006,14 however, EPA rejected this demand, saying it lacked
authority to set NSPSs for GHGs.
Review of the final rule was sought in the D.C. Circuit.15 In September, 2006,
the court severed the portion of the case dealing with regulation of GHGs, titling it


11 Civ. Action No. 3:03CV984 (PCD) (D. Conn.) (filed June 4, 2003).

2006).



New York v. EPA.16 In September, 2007, a few months after the Supreme Court
decision in Massachusetts v. EPA, this severed case was remanded to EPA for further
proceedings in light of that decision (this section infra).
Suits Enforcing the CAA Against Stationary Sources.
In Northwest Environmental Defense Center v. Owens Corning Corp.,
environmental groups invoke the CAA citizen suit provision to enforce the act’s
“new source review” requirement as to GHG emissions.17 They contend that Owens
Corning is constructing a manufacturing plant in Oregon with the potential to emit
more than 250 tons per year of harmful gases, without having obtained the required
permit.18 The principal such gas is HCFC-142b, which plaintiffs contend is a potent
GHG. In a preliminary ruling, the court held that plaintiffs have standing,
notwithstanding that the climate change impacts of the plant’s GHG emissions would
be “indirect.” Anticipating the Supreme Court’s rationale for granting standing in
Massachusetts v. EPA, the court found that standing was not precluded by the fact
that the injury to plaintiffs would be shared with many others, nor because the relief
sought would not lead to a complete elimination of climate change impacts.
In another proceeding, this time before EPA’s Environmental Appeals Board,
Sierra Club objected to the issuance of a CAA Prevention of Significant
Deterioration (PSD) permit by a state agency for construction of a coal-fired electric
power plant. In re Christian County, LLC, PSD Appeal No. 07-01 (decided January
28, 2008). Sierra Club’s argument was that the permit must contain a “best available
control technology” (BACT) limit on the plant’s CO2 emissions. The petition was
denied because Sierra Club had not raised its argument during the public comment
period on the draft permit, but the issue is still alive. Sierra Club is also the
petitioner in another case before the Board, In re Deseret Power Electric
Cooperative, PSD Appeal No. 07-03 (filed October 1, 2007), in which it raised the
CO2 BACT issue during the public comment period and, therefore, preserved the
issue for appeal.
In re Deseret involves an EPA-issued PSD permit to construct a new waste-
coal-fired utility generating unit at an existing power plant. The PSD BACT issue
stems from the fact that the CAA requires a new “major emitting facility” in a PSD
area to install BACT “for each pollutant subject to regulation under this act.”19 Sierra
Club argues that in light of the Massachusetts v. EPA holding that GHGs are “air
pollutants” under the act, CO2 is “subject to regulation” by the CAA. To the contrary,
argues EPA, the phrase “subject to regulation” refers only to pollutants that the
agency has specifically regulated, and since it has yet to issue a regulation limiting
CO2 emissions, BACT for CO2 is not required here.

Mobile Sources of GHG Emissions
The Section 202 Petition Denial and the Second EPA General
Counsel Memorandum.
In 1999, 19 organizations petitioned EPA to regulate emissions of GHGs (CO2,
methane, nitrous oxide, and hydrofluorocarbons) from new motor vehicles. The
rulemaking petition cited the agency’s alleged mandatory duty to do so under CAA
section 202(a)(1).20 That section directs the EPA Administrator to prescribe emission
standards for “any air pollutant” from new motor vehicles “which, in his judgment
cause[s], or contribute[s] to air pollution which may reasonably be anticipated to
endanger public health or welfare.”
In 2003, EPA denied the section 202 petition.21 Much of the agency’s rationale
followed a new General Counsel memorandum, issued the same day.22 Contrary to
its Clinton Administration precursor, this new OGC memorandum concluded that the
CAA does not grant EPA authority to regulate CO2 and other GHG emissions for
their climate change impacts.
Massachusetts v. EPA: The Challenge to EPA’s Petition Denial.
D.C. Circuit Decision.
EPA’s denial of the section 202 petition prompted a suit in the D.C. Circuit by
twelve states (CA, CT, IL, MA, ME, NJ, NM, NY, OR, RI, VT, WA) and others.
Opposing the challenge, besides EPA, were ten state intervenors (AK, ID, KS, MI,
ND, NE, OH, SD, TX, UT), plus several automobile- and truck-related trade groups.
In 2005, a split panel in Massachusetts v. EPA rejected the suit.23 The two
judges supporting rejection, however, did so for different reasons. Judge Randolph,
assuming that EPA had CAA authority to regulate GHG emissions, spoke to whether
EPA properly exercised its discretion in choosing not to wield that authority. Recall
that CAA section 202(a)(1) directs the EPA Administrator to prescribe standards for
any motor vehicle emissions that “in his judgment”24 cause harmful air pollution.
Judge Randolph read “in his judgment” broadly to allow EPA consideration of not
only “scientific uncertainty” about the effects of GHGs, but also “policy
considerations” that justified not regulating. Thus, EPA in his view was entitled to

rely, as it did, on such factors as the fact that new motor vehicles are but one of many
sources of GHG emissions, resulting in an inefficient piecemeal approach to climate
change, and efforts to promote fuel cell and hybrid vehicles. He concluded that EPA
had properly exercised its 202(a)(1) discretion in denying the petition for rulemaking.
By contrast, Judge Sentelle held that petitioners lacked standing.25
In dissent, Judge Tatel asserted that at least one petitioner had standing.
Massachusetts, he said, had shown the possibility of injury from global-warming-
induced rising sea levels. On the merits, he found first that EPA has the authority
under section 202(a)(1) to regulate GHG emissions. Second, he concluded that
EPA’s 202(a)(1) discretion does not extend to policy considerations, as Judge
Randolph held, but relates exclusively to whether the emissions cause harm.
Supreme Court Decision.
In Massachusetts v. EPA, the Court ruled 5-4 for petitioners on all three issues
in the case — standing, authority, and discretion.26 First, Massachusetts has standing
to bring the claim. Second, EPA has authority to regulate motor vehicle GHGs under
section 202, since “air pollutant” includes GHG emissions. And third, the phrase “in
his judgment” in section 202 does not allow EPA to exercise discretion against
regulating based on policy considerations. The ruling in favor of petitioners was
forecast early in the majority opinion by its opening sentences: “A well-documented
rise in global temperatures has coincided with a significant increase in the
concentration of carbon dioxide in the atmosphere. Respected scientists believe the
two trends are related.”27 (Nor did the dissenters dispute this.)
Most of the decision is devoted to standing. The Court found that petitioners
had two factors in their favor. First, the CAA specifically authorizes challenges to
agency action unlawfully withheld, such as here.28 A litigant to whom Congress has
accorded such a procedural right, said the Court, “can assert that right without
meeting the normal standards for redressability and immediacy”29 — two
prerequisites of the standing test. Second, the Court found it “of considerable
relevance”30 that the petitioner injury on which it focused — Massachusetts’s loss of
shore land from global-warming-induced sea level rise — was that of a sovereign
state. States are “not normal litigants for the purposes of invoking federal31
jurisdiction,” said the Court, noting their quasi-sovereign duty to preserve their
territory.


25 The test for whether a plaintiff in federal court has standing is described in greater detail
in the following discussion of the Supreme Court’s decision on appeal of the D.C. Circuit
ruling.
26 127 S. Ct. 1438 (2007).
27 Id. at 1446.
28 CAA § 307(b)(1), 42 U.S.C. § 7607(b)(1).
29 127 S. Ct. at 1453.
30 Id. at 1454.
31 Id.

Having described petitioners’ favored position in establishing standing, it was
surprising that the Court then undertook a traditional standing analysis. As to the
first prong of the standing test — whether plaintiff has demonstrated actual or
imminent “injury in fact” of a concrete and particularized nature — the Court homed
in on Massachusetts’s status as owner of much of the shore land being lost to sea
level rise. That this injury may be widely shared with other coastal states does not
disqualify this injury, said the Court; it is nonetheless concrete.
The second prong of the standing test is causation, requiring that the injury of
which the plaintiff complains is fairly traceable to the defendant. EPA did not
dispute the existence of a causal relationship between GHG emissions and climate
change. It did argue, however, that any reduction in GHG emissions achieved
through the current litigation would be too small a portion of worldwide GHG
emissions to make a cognizable difference in climate change. In a ruling that may
be of benefit to environmental plaintiffs in many contexts, the Court held that even
an agency’s refusal to take a “small incremental step”32 that would result in only a
modest reduction in worldwide GHG emissions, is enough for standing purposes.
The third and final prong of the standing test is redressability, demanding that
the remedy sought by the plaintiff is one that is likely to redress his/her injury. Here,
the remedy sought was EPA regulation of GHG emissions from new motor vehicles.
The Court found that this remedy satisfied redressability because while it would not
by itself reverse climate change, it would nonetheless slow or reduce it. Nor, given
the “enormity”33 of the potential effects of climate change, was it relevant to the
Court that the full effectiveness of the remedy would be delayed until existing cars
and trucks on the road were largely replaced by new ones.
In contrast with the majority opinion’s lengthy discourse on standing, its
disposition of the CAA issues in the case is quite brief. On the authority question,
the CAA’s broad definition of “air pollutant” simply could not, the Court said, be
squared with EPA’s view that GHGs are not included. The Court rejected EPA’s
argument that federal laws enacted following enactment of this definition — laws
emphasizing interagency collaboration and research — suggest that Congress meant
to curtail EPA’s power to use mandatory regulations in addressing air pollutants.
Nor was the Court impressed with EPA’s argument that “air pollutant” in the CAA
could not include vehicle GHG emissions because EPA standards for such emissions
could be satisfied only by improving fuel economy, a goal assigned to the
Department of Transportation under a different statute (the Energy Policy and
Conservation Act34).
Finally, on the discretion issue, the majority concluded that “in his judgment”
refers only to whether an air pollutant “may reasonably be anticipated to endanger
public health or welfare.” Thus, said the Court, EPA can avoid taking further action
in response to the section 202 petition “only if it determines that greenhouse gases
do not contribute to climate change or if it provides some reasonable explanation as


32 Id. at 1457.
33 Id. at 1458.
34 49 U.S.C. § 32902.

to why it cannot or will not exercise its discretion.” It rejected EPA’s stated policy
reasons for refusing to regulate GHG emissions, such as its claim that voluntary
executive branch programs already provide an effective response to climate change
and that unilateral EPA regulation of vehicle GHG emissions could weaken U.S.
efforts to persuade developing countries to reduce the GHG intensity of their
economies. Such reasons “have nothing to do with whether greenhouse gas
emissions contribute to climate change.”35 In short, said the Court, the only question
is whether sufficient information exists to make an endangerment finding under
section 202.
Accordingly, the Supreme Court reversed the D.C. Circuit opinion and
remanded the case to that court for further proceedings.36 On September 14, 2007,
the D.C. Circuit vacated EPA’s denial of the section 202 petition and remanded the
matter to the agency.
A four-justice dissent by Chief Justice Roberts in Massachusetts v. EPA
disputed the majority’s holding of standing. A dissent by Justice Scalia for the same
four justices argued that agency policy preferences may appropriately be considered
as part of EPA’s decision whether to issue a “judgment,” conceding that the
judgment, if made, must be limited to whether vehicle GHG emissions cause
endangerment. Justice Scalia also disputed the majority’s holding that “air pollutant”
in section 202 includes GHGs.
Implications of Supreme Court Decision.
The Court’s decision leaves EPA with three options: make a finding that motor
vehicle GHG emissions may “endanger public health or welfare” and issue emissions
standards; make a finding that such emissions do not satisfy that prerequisite; or
decide that climate change science is so uncertain as to preclude making a finding
either way (or cite some other “reasonable explanation” why it will not exercise its
discretion either way).37 As to the state of climate change science, the Court’s focus
on the policy reasons EPA gave as part of exercising its “judgment” obscures the fact
that the agency’s rejection of the petition stemmed in part from expressions of
scientific uncertainty in a 2001 National Research Council report on the science of
climate change. Whether scientific reports since the petition rejection in 2003 have
foreclosed the scientific-uncertainty rationale is beyond the scope of this report.
The EPA Administrator did say after the decision that although it bars EPA use
of policy considerations as a basis for denying the petition, it left open whether the
agency can invoke them when actually writing the regulations, should the agency

36 Three weeks after the decision in Massachusetts v. EPA, the Senate held a hearing
devoted exclusively to it: The Implications of the Supreme Court’s Decision Regarding
EPA’s Authorities with Respect to Greenhouse Gases Under the Clean Air Act: Hearing
Before the Senate Comm. on Env’t and Pub. Works (April 24, 2007) (hereinafter Senate
hearing).
37 Justice Scalia’s dissent characterizes EPA’s three options similarly: 127 S. Ct. at 1472.

make an endangerment finding.38 In this regard, it should be noted that CAA section
202 does not explicitly impose any stringency or other criteria on GHG emission
standards promulgated under the section. Given the wide latitude EPA has in setting
section 202 standards for GHGs, the possibility presents itself that EPA, following
an endangerment finding, could set voluntary standards, or standards pegged to the
CAFE standards for fuel economy, or standards that must be complied with only after
the President certifies that developing nations have put adequate GHG emission
limits into effect. We offer no opinion here as to the legal viability of these options.
On May 14, 2007, the President asked EPA to have CAA regulations limiting
vehicle GHG emissions in place by the end of 2008 and to use the President’s 2007
State of the Union proposal for raising the CAFE standards as a guide.39 As late as
early December, 2007, EPA was consistently stating that it intended to issue
proposed regulations by the end of 2007. However, the enactment of the Energy
Independence and Security Act in December, 2007,40 with its increase in CAFE
standards, led EPA to back off from any firm deadline for issuance of mobile-source
GHG emission standards. In January, 2008, letters from the Massachusetts v. EPA
petitioners asked the EPA Administrator when he intended to act,41 prompting EPA
to respond that it did not have a specific time line. Most recently, EPA announced
by letter that it will issue during spring, 2008, an advance notice of proposed
rulemaking (ANPR) addressing the full range of Massachusetts v. EPA’s
ramifications throughout the CAA, including the section 202 standards42 — on the
ground that regulation under section 202 could automatically result in other CAA
regulations applying to stationary sources and other mobile sources. In response, the
Massachusetts v. EPA petitioners requested the D.C. Circuit to order EPA to comply
with the Supreme Court’s remand and the Circuit’s mandate within 60 days
(choosing one of the three options noted earlier), arguing that the proposed ANPR
extended well beyond the narrow section 202 endangerment issue in the case.43

As the EPA letter confirms, the Court’s ruling in Massachusetts v. EPA has
many implications beyond its four corners.
On the substantive (non-standing) side, the Court’s ruling upholding CAA
coverage of GHG emissions from mobile sources likely will improve the prospects
of litigation seeking to have EPA restrict GHG emissions from stationary sources as
well. The stationary-source provisions of the CAA use terms similar to that of
section 202 — in particular, “air pollutant,” “in his judgment,” and “endanger.”44 As
the above discussion of New York v. EPA indicates, such an effort to compel EPA
regulation of stationary source GHGs is already underway as to NSPSs. Further, if
EPA sets a national ambient air quality standard for CO2, GHGs would be covered
under the CAA’s new source review permitting program for major emitting facilities
and modifications in Prevention of Significant Deterioration areas.45 Presumably,
best available control technology for CO2 emissions would then have to be installed
on such facilities.46
On the mobile-source side, Massachusetts v. EPA is expressly relied upon by
California in three rule-making petitions asking EPA to regulate GHG emissions
from mobile sources other than those at issue in that decision — in particular (1)
ocean-going vessels under CAA section 213(a)(4), which authorizes federal emission
standards for “new nonroad engines and new nonroad vehicles” (petition submitted
October, 2007);47 (2) aircraft under CAA section 231 (submitted December, 2007);48
and (3) new nonroad vehicles and engines excluding aircraft, locomotives, and
vessels (i.e., farm and construction equipment, lawn and garden equipment, RVs,
etc.) under CAA sections 202 and 213(a)(4) (submitted January, 2008).
Non-substantively, the Supreme Court’s ruling on standing will likely be pivotal
to the fortunes of plaintiffs in other climate change litigation. The question will be

throughout the CAA, is similar to one of the policy arguments made by EPA in denying the
original 1999 petition, namely that establishing motor vehicle GHG standards now —
would result in an inefficient piecemeal approach to addressing the climate
change issue.... A sensible regulatory scheme would require that all significant
sources and sinks of GHG emissions be considered in deciding how best to
achieve any needed emission reductions.
68 Fed. Reg. at 52,391. As noted, the Supreme Court decision held that such policy
considerations are irrelevant to the agency’s determination on the section 202 petition.
44 See, e.g., CAA § 108(a)(1)-(2), 42 U.S.C. § 7408(a)(1)-(2) (requiring the EPA
Administrator to maintain a list of each “air pollutant” “emissions of which, in his judgment,
cause or contribute to air pollution which may reasonably be anticipated to endanger public
health or welfare,” and then issue air quality criteria and national ambient air quality
standards for that air pollutant).

the extent to which the Court’s finding of standing was contingent, as it obliquely
suggested, on the existence of a state-sovereign plaintiff49 and the presence in the
CAA of an explicit provision allowing the filing of administrative petitions.
Ironically, the “environmental win” in Massachusetts v. EPA has thwarted the
environmental side in a climate-change-related nuisance case, and may do so in
others. One court used the decision as peripheral support for dismissing a nuisance
action on “political question” grounds, reasoning that the Supreme Court has now
found authority over GHG emissions to reside in the Federal Government.50 In the
future, the decision may also undermine federal common law claims, on the
argument that Congress intended to leave no room for courts to develop overlapping
federal common law restricting GHG emissions.
II. Wildlife Protection Statutes
Marine Mammal Protection Act
The Marine Mammal Protection Act (MMPA)51 bars the taking of marine
mammals, with exceptions. One exception is for “incidental takings” by specified
activities.52 It provides that persons “engage[d] in a specified activity (other than
commercial fishing) within a specified geographical region” may request the
Secretary of the Interior or Commerce to authorize, for up to five years, the
incidental, but not intentional, taking of small numbers of marine mammals. The
Secretary must grant the authorization if he/she makes certain findings — including
that the effect of the incidental take will be “negligible” — and promulgates rules
setting out permissible methods of taking by the specified activity.
In Center for Biological Diversity v. Kempthorne, No. 07-CV-00141 (D.
Alaska), transferred from No. 07-CV-00894 (N.D. Cal. filed February 13, 2007),
environmental groups challenge one such “incidental taking” rule promulgated by the
Fish and Wildlife Service (FWS), Department of the Interior. The rule authorizes the
incidental take of polar bears and Pacific walrus for five years resulting from oil and
gas activities in the Beaufort Sea and adjacent coastal areas of the Alaska north
slope.53 Plaintiffs argue that the rule violates the MMPA and thus is arbitrary and
capricious by permitting more than a “negligible” impact on the species, based on the

combined impact of oil-and-gas activities and climate change.54 (This lawsuit also
contains a National Environmental Policy Act claim, discussed in Section IV.)
Endangered Species Act
Under the Endangered Species Act (ESA),55 animals (and plants) may be listed
as endangered or threatened. As to a listed species, two of the act’s provisions are
particularly relevant. Section 9 makes it unlawful to “take” a member of a listed
endangered species,56 and has been extended by regulation to most threatened
species.57 Exceptions from the take prohibition are possible, as through incidental
take permits. The other provision, section 7, demands that each federal agency
“insure that any action authorized, funded, or carried out by such agency ... is not
likely to jeopardize the continued existence of any endangered species or threatened
species or result in the destruction or adverse modification of [designated critical
habitat] of such species....”58 To achieve this goal, section 7 directs a federal agency,
upon finding in a biological assessment that a proposed agency action is “likely to
affect” a listed species, to consult with the appropriate wildlife agency — the FWS
or National Marine Fisheries Service (NMFS). This is called “section 7
consultation.” Then, the FWS or NMFS prepares a “biological opinion” concluding
either that the proposed action would not violate the no-jeopardy/adverse-
modification mandate, or that it would violate the mandate, in which case FWS or
NMFS must suggest “reasonable and prudent alternatives” that would not violate the
mandate.
In Natural Resources Defense Council v. Kempthorne, 506 F. Supp. 2d 322
(E.D. Cal. 2007), environmental and sport fishing groups attacked the FWS
biological opinion prepared for the 2004 Long-Term Central Valley Project and State
Water Project Operations Criteria and Plan and certain related future actions. The
biological opinion concluded that project operations would not jeopardize the
continued existence of the Delta smelt, a threatened species, or adversely modify its


54 In a case of the same name, Center for Biological Diversity v. Kempthorne, No. 07-5109
(N.D. Cal. filed October 4, 2007), environmental groups challenge the Secretary of the
Interior’s alleged failure to issue updated stock assessment reports for marine mammals
under its jurisdiction (sea otters, polar bears, walrus, and manatees) within the time frames
mandated by the MMPA. The complaint asserts as examples that since the last stock
assessment reports on the polar bear and walrus, “global warming has caused the loss of sea
ice upon which [those species] depend....”
55 16 U.S.C. §§ 1531-1544. The ESA defines “take” similarly to the MMPA, note 52. 16
U.S.C. § 1532(19).
56 16 U.S.C. § 1538(a)(1)(B)-(C).
57 By general rule, the Fish and Wildlife Service has extended all of the endangered species
prohibitions to threatened animals. 50 C.F.R. § 17.31. “Special rules,” withdrawing
particular threatened species from aspects of the general regime, have been promulgated for
those species with atypical management needs, such as grizzly bears. 50 C.F.R. § 17.40(b).
58 16 U.S.C. § 1536(a)(2). Because section 7 is more easily triggered when the species’
habitat receives a formal designation as “critical habitat,” litigation to compel such
designation is another aspect of environmental groups’ efforts to use the ESA against global
warming. See ESA § 4(a)(3), 16 U.S.C. § 1533(a)(3).

designated critical habitat — that is, would not violate ESA section 7. The court,
however, held that the biological opinion was arbitrary and capricious in ignoring
data about climate change that may adversely affect the Delta smelt and its habitat.
The court observed, for example, that the opinion was based on the assumption that
the hydrology of the waters affected by the 2004 plan would follow historical patterns
for the next 20 years, an assumption that studies on the potential effects of climate
change on water supply reliability did not support.
A companion case pending before the same judge, Pacific Coast Federation of
Fishermen’s Associations/Institute for Fisheries Resources v. Gutierrez, No. 1:06-
CV-00245 (E.D.Cal. filed August 9, 2005), challenges the NMFS biological opinion
prepared in connection with the same project for various salmon and trout species.
(A NEPA claim in this suit was dismissed. 2007 Westlaw 1752289 (E.D. Cal. June

15, 2007).)


It may be only a matter of time before several more ESA cases are filed. In an
effort spearheaded by the Center for Biological Diversity, multiple petitions have
been filed to have animals listed as endangered or threatened due in various degrees
to climate change impacts on their habitat. Should such species then be listed and
their critical habitats designated, the Center is likely to test in court whether
substantial GHG sources run afoul of protections afforded those species by the ESA.
Only one climate-change-related proposal to list a species has reached the
actual listing stage thus far — that by NMFS bestowing threatened status on the
staghorn coral and elkhorn coral.59 Considerably more attention to ESA implications,
however, has been directed at the January, 2007 FWS proposal to list the polar bear
as threatened, in fulfillment of a settlement agreement with environmental groups
including the Center for Biological Diversity.60 The polar bear proposal ties in with
widely publicized studies as to the impact of climate change on the Arctic —
particularly, the loss of sea ice required by polar bears as habitat.61 In addition to the
coral and polar bear, the Center has petitioned the FWS to list as either endangered
or threatened Kittlitz’s murrelet, a seabird (2001), 12 species of penguins (2006),62


59 89 Fed. Reg. 26852 (May 9, 2006). The Center for Biological Diversity has also settled
a suit requiring NMFS to designate critical habitat for ESA-listed corals. The proposed
critical habitat rule is at 73 Fed. Reg. 6895 (February 6, 2008).
60 72 Fed. Reg. 1,064 (January 9, 2007). Under ESA section 4(b)(6)(A), the Secretary of
the Interior is required to make his determination for or against listing within one year of the
proposed listing — unless a six-month extension is claimed under ESA section 4(b)(6)(B).
No extension having been claimed, the polar bear determination was due by January 9,

2008, but had not been made as of the date of this report. On March 10, 2008,


environmental groups sued the Secretary of the Interior to compel an up or down
determination. Center for Biological Diversity v. Kempthorne, No. 08-1339 (N.D. Cal. filed
March 10, 2008).

(2007), the ribbon seal (2007), and the Pacific walrus (2008). In each instance, the
Center asserts global warming to be a cause, principal or otherwise, of the species’
plight.
If the polar bear, for example, is listed, would starting up a new fossil-fuel-fired
power plant violate section 9 — cause a “take” — through the effects of its GHG
emissions, via climate change, on polar bear habitat?63 Notable here is that “take”
is statutorily defined to include “harm” to a member of a listed species, and “harm,”
in turn, is defined by regulation to include certain “significant habitat modification[s]
or degradation[s].”64 The crux, presumably, is whether the causal link between the
power plant’s GHG emissions and the effect on the species habitat is sufficiently
direct and substantial to constitute a “take,” a question beyond the scope of this
report. If a take is found, the power plant would require an incidental take permit to
operate, such permit likely containing restrictions on the amount of GHGs that could
be emitted. Likewise, would a federal agency issuing a permit for powerplant
construction have to initiate section 7 consultation?
To be sure, the ESA and its regulations do contain mechanisms — e.g.,
incidental take permits, “reasonable and prudent alternatives,” and “special rules” for
threatened species — that can ease the act’s constraints on human activities affecting
listed species.
III. Energy Statutes
Energy Policy and Conservation Act
In Center for Biological Diversity v. National Highway Traffic Safety
Administration, 508 F.3d 508 (9th Cir. 2007), 11 states (CA, CT, ME, MA, NJ, NM,
NY, OR, RI, VT, MN), four environmental groups, and others attacked a 2006 rule
promulgated by the National Highway Traffic Safety Administration (NHTSA) under
the Energy Policy and Conservation Act (EPCA). The rule established corporate
average fuel economy (CAFE) standards for light-duty trucks — defined by NHTSA
to include many SUVs, vans, and pickup trucks — in model years 2008 through

2011.


62 (...continued)
Secretary of the Interior has 12 months after receiving a petition indicating that action may
be warranted to either propose listing or find that no action is warranted.
63 See generally Brendan R. Cummings and Kassie R. Siegel, Ursus maritimus: Polar Bears
on Thin Ice, Natural Res. & Env’t (ABA) 3 (Fall 2007) (discussing how “the listing process
for the polar bear highlights the possibilities and limitations of using the ESA to address
otherwise unregulated GHG emissions”).
64 50 C.F.R. §§ 17.3 (Fish and Wildlife Service), 222.102 (NOAA Fisheries).

EPCA says that the light-truck CAFE standard shall be the “maximum feasible”
standard that manufacturers can achieve in a given model year.65 The court found
that even assuming NHTSA may use a cost-benefit analysis to determine the
“maximum feasible” standard, it was arbitrary and capricious not to include in the
analysis the benefit of carbon emissions reduction — calling this “the most
significant benefit of more stringent CAFE standards.”66 NHTSA had argued, for
example, that the wide range of values put forward in studies as to how the benefits
of reduced GHG emissions should be monetized justified placing no value on that
benefit in its cost-benefit analysis. The court countered that while there is indeed a
range of values in the studies, they are all greater than zero. Accordingly, the court
remanded the CAFE standard to NHTSA for the agency to include a monetized value
for carbon emission reduction in its analysis of the proper CAFE standard. (There
was also a climate-change-related NEPA claim in this lawsuit, discussed in Section
IV.)
Outer Continental Shelf Lands Act
In a petition for review filed with the D.C. Circuit, the Center for Biological
Diversity challenges the June, 2007 approval by the Secretary of the Interior of the
Outer Continental Shelf Oil and Gas Leasing Program 2007-2012. Center for
Biological Diversity v. U.S. Dep’t of Interior [sic], No. 07-1247 (D.C. Cir. filed July
2, 2007). Plaintiff alleges that the Secretary violated the Outer Continental Shelf
Lands Act67 by failing to disclose or analyze the environmental and economic
impacts from “the greenhouse gas emissions that would result from use of oil and gas
produced as a result of the [Program].”68 This language indicates that it is not the
GHG emissions from the oil and gas production itself that is at issue, but rather the
GHG emissions resulting from the “use” of that oil and gas in cars, powerplants, or
wherever. (There was also a climate-change-related NEPA claim in this lawsuit,
discussed in Section IV.)
IV. Information Statutes
Much of the climate change litigation is based on statutory requirements that
the government generate, compile, or disclose information.
National Environmental Policy Act
To be sure, the National Environmental Policy Act (NEPA) is more than just an
information statute, declaring as it does a sweeping policy that the federal
government must consider the environmental impacts of its actions. However,
NEPA ensures that such environmental consideration will occur chiefly through the


65 49 U.S.C. § 32902(a).

filed August 3, 2007.

production of information, in the form of environmental assessments and
environmental impact statements, and does not require that an agency choose from
among its options the one with the least environmental impact.
The NEPA cases involving climate change represent the oldest and most
numerous category of climate change litigation. Again, not all cases are mentioned
in this report.69
The dominant issue has been whether plaintiffs have standing to sue — as
mentioned, an issue on which plaintiffs may be helped by the 2007 Supreme Court
decision in Massachusetts v. EPA. Thus, all the standing issues discussed here
should be viewed through the prism of that decision. The standing determination has
been particularly difficult in the context of NEPA, which confers only a procedural
right (having a federal agency prepare an adequate environmental impact statement
(EIS)), not a substantive right (having the agency select a particular course of action
after preparing the EIS). Where courts have found standing and reached the merits,
they have usually accepted that climate change impacts in the proper circumstances
are a required consideration in an EIS.70
District of Columbia Circuit.
Standing barriers have proved particularly daunting in the D.C. Circuit, thus it
is here that Massachusetts v. EPA may have its greatest effect. In the first significant
climate change case, City of Los Angeles v. National Highway Traffic Safety Admin.,
912 F.3d 478 (D.C. Cir. 1990), the city attacked a NHTSA decision not to prepare
an EIS when it set the corporate average fuel economy standard at 26.5 mpg for71
model year 1989 passenger cars — below the statutory default setting of 27.5 mpg.
A majority of the D.C. Circuit panel concluded that petitioners had standing based
on their argument that had NHTSA done an EIS considering the climate change
impacts of its one mpg rollback, the agency might have rejected it. This provided the
requisite causal nexus, said the majority, between NHTSA’s decision not to do an
EIS and climate change. In dissent, however, one judge argued that Article III
demanded a more precise causal showing, with clear proof of a nexus between the
agency action and harm to the petitioners. On the merits, one judge in the majority
concluded that NHTSA had “inadequately explained why the admitted increase in
carbon dioxide is insignificant within the context of the environmental harm posed

CAFE standard involved a climate change argument.

by global warming.”72 She would have remanded NHTSA’s NEPA decision but left
the rollback in place in the meantime. Because the other majority judge ruled for the
agency, however, the petition was denied.
The plaintiff-friendly City of Los Angeles standard for finding global-warming-
based standing was to prove short-lived. Six years later, a divided D.C. Circuit
declared en banc that to obtain standing, a procedural-rights plaintiff must show not
only that the government omitted a required procedure, but that it is substantially
probable that the procedural omission will cause a particularized injury to the
plaintiff73 — adopting the dissenter’s position in that case. To the extent City of Los
Angeles dispensed with the second, causation-of-a-particularized-plaintiff-injury
requirement, it was expressly overruled. Still later court decisions, however, have
cast doubt on this strict standard.74
In Foundation on Economic Trends v. Watkins, 794 F. Supp. 395 (D.D.C. 1992),
the standing bar was raised during, rather than after, the litigation. Plaintiffs claimed
that NEPA required the Secretaries of Energy, Agriculture and the Interior to evaluate
the effect on climate change of 42 actions and programs under their authority.
Plaintiffs’ standing argument was based on “informational standing,” under which
failure to do an EIS discussing possible climate change impacts satisfies the injury
requirement of standing merely by harming plaintiffs’ programs for disseminating
information about climate change to the public. In so arguing, plaintiffs relied on a
line of D.C. Circuit decisions going back two decades. Unfortunately for them,
however, informational standing was limited by the D.C. Circuit during the pendency
of their suit. An amended complaint by the individual plaintiff, arguing that his
expected use of his oceanfront cottage may be curtailed if oceans rise from climate
change, was also rejected. Among other things, said the court, the plaintiff had not
met the causation requirement of standing in that he had not related the
environmental harm he predicted to any of the 42 challenged agency actions.
“[T]here is no ‘global warming’ exception to the standing requirements of Article III
or the [Administrative Procedure Act],”75 it asserted.
In a suit described in Section III, Center for Biological Diversity v. U.S. Dep’t
of Interior [sic], No. 07-1247 (D.C. Cir. filed July 2, 2007), plaintiff charges that the
Secretary of the Interior failed to analyze in the EIS for his five-year Outer
Continental Shelf leasing program (1) the GHG emissions resulting from the use of
the oil and gas produced under the program, and (2) the effects of global warming on
the resources affected by the program “including, but not limited to, polar bears,
walrus, and corals.”


72 912 F.2d at 501.
73 Florida Audubon Society v. Bentsen, 94 F.3d 658 (D.C. Cir. 1996). The four dissenting
judges argued that the majority had “misapplied the doctrine of standing to the assertion of
a procedural right, such as the preparation of an EIS, with the consequence that it will be
effectively impossible for anyone to bring a NEPA claim in the context of a rulemaking with
diffuse impact.” Id. at 673.
74 See, e.g., Friends of the Earth v. Laidlaw Environmental Services, 528 U.S. 167 (2000).
75 794 F.2d at 401.

In Montana Environmental Information Center v. Johanns, No. 07-CV-01331
(D.D.C. filed July 23, 2007), challenge is made to the Department of Agriculture’s
Rural Utility Service’s use of low-interest loans to help finance the construction of
at least eight new coal-fired powerplants. The charge is that the EIS for one plant is
deficient because it fails to consider the cumulative impacts of GHG emissions from
the eight new plants.
Ninth Circuit.
The standing barriers in the D.C. Circuit seem to be attenuated in the Ninth
Circuit where, as far as research reveals, plaintiffs raising climate change claims in
NEPA suits have yet to encounter standing problems.
In 2002, environmental groups sued the Overseas Private Investment Corp.
(OPIC) and Export-Import Bank of the United States alleging continued failure to
comply with NEPA. These federal agencies provide insurance, loans, and loan
guarantees for overseas projects, or to U.S. companies that invest in overseas
projects. Plaintiffs alleged that these overseas projects include oil and gas extraction
and refining, and power plants, which together result in the annual emission of
billions of tons of GHGs, causing climate change in the United States.
In 2005, the district court held that plaintiffs had standing, given what it saw to
be the relaxed standards in the Ninth Circuit for showing standing in cases alleging
procedural violations — here, failure to prepare an EIS.76 Friends of the Earth v.
Mosbacher, 2005 Westlaw 2035596 (N.D. Cal. 2005). It is “reasonably probable,”
said the court, that emissions from projects supported by the defendants will threaten
plaintiffs’ concrete interests. In 2007, the court reached the merits, holding on
summary judgment motions that defendants need not prepare a programmatic EIS for
the energy projects they finance, and that neither side had shown, as a matter of law,
that energy projects specifically listed in the complaint are or are not “major Federal
actions” requiring an EIS. 488 F. Supp. 2d 889 (N.D. Cal. 2007).
In Border Power Plant Working Group v. Dep’t of Energy, 260 F. Supp. 2d 997
(S.D. Cal. 2003), plaintiff challenged the environmental assessment accompanying
applications for permits and federal rights of way to build electricity transmission
lines connecting new power plants in Mexico with the power grid in Southern
California. In part because four of its members were seen to have procedural


76 In finding standing, the judge repudiated an earlier climate change/standing decision of
the same court. In Center for Biological Diversity v. Abraham, 218 F. Supp. 2d 1143 (N.D.
Cal. 2002), plaintiffs had sought enforcement of the Energy Policy Act as it related to the
acquisition of alternative fuel vehicles by the United States. In rejecting standing, this
decision spurned plaintiffs’ climate change concerns as “too general, too unsubstantiated,
too unlikely to be caused by defendant’s conduct, and/or too unlikely to be redressed by the
relief sought to confer standing.” In Friends of the Earth, the court neutralized this
pronouncement by noting that “Center for Biological Diversity was decided before the Ninth
Circuit clarified in [Citizens for Better Forestry v. U.S. Dep’t of Agriculture, 341 F.3d 961,th
972 (9 Cir. 2003)] that environmental plaintiffs raising procedural concerns need not
present proof that the challenged federal project will have particular environmental effects.”

standing, the plaintiff organization was held to have organizational standing.77 The
court’s standing discussion made no mention of climate change, however, perhaps
because climate change was only a small part of plaintiff’s case. On the merits, the
court agreed with plaintiff that the environmental assessment was legally inadequate
because, among other things, it failed to discuss CO2 emissions from the powerplants
and “[t]he record shows that carbon dioxide ... is a greenhouse gas.”78
The most recent NEPA/climate change decision by the Ninth Circuit, Center for
Biological Diversity v. NHTSA, 508 F.3d 508 (9th Cir. 2007), offers a deja vu to City
of Los Angeles, discussed earlier in this section. Both cases involve a NHTSA rule
setting a corporate average fuel economy (CAFE) standard — this time, for light-duty
trucks (model years 2008-2011)79 — and in both cases, the agency did no EIS.
Petitioners include 11 states (CA, CT, ME, MA, NJ, NM, NY, OR, RI, VT, MN) and
four environmental groups. In sharp contrast with earlier NEPA/climate-change
decisions, the United States in this case did not contest standing and the court
decision does not mention it.
On the merits, the court held that NHTSA’s environmental assessment for its
CAFE rule, finding no significant impact, was inadequate owing to, among other
things, its analysis of the rule’s cumulative impacts from GHG emissions. Said the
court: “The impact of greenhouse gas emissions on climate change is precisely the
kind of cumulative impacts analysis that NEPA requires agencies to conduct.”80 Nor
did the Energy Policy and Conservation Act, the statute authorizing CAFE standards,
limit NHTSA’s duty to assess environmental impacts such as climate change. More
specifically, while NHTSA’s assessment indicated the expected amount of CO2
emitted by light-duty trucks under the new CAFE standard, it failed to “evaluate the
‘incremental impact’ that these emissions will have on climate change ... in light of
other past, present, and reasonably foreseeable actions such as other light truck and
passenger automobile CAFE standards.”81 Finally, the court invoked the well-settled
principle that an EIS must be prepared if substantial questions are raised as to
whether a proposed project may have significant environmental impact, and held that
petitioners’ evidence raised the necessary level of doubt. Thus, the court ordered
preparation of a full EIS. (There was also a climate change-related Energy Policy and
Conservation Act claim, discussed in Section III.)
In Center for Biological Diversity v. Kempthorne, No. 07-CV-00141 (D.
Alaska), transferred from No. 07-CV-00894 (N.D. Cal. filed February 13, 2007),
environmental groups challenge a Fish and Wildlife Service “incidental taking” rule.

Pacific walrus by oil and gas activities in the Beaufort Sea and adjacent coastal areas
of the Alaska north slope.82 Plaintiffs challenge the environmental assessment and
finding of no significant impact, charging that the Service put out the rule “without
seriously analyzing the effects of climate change on them or their habitat.” The
accusation is not that the oil and gas activities themselves contribute to climate
change, but that direct harms to polar bears and walruses from those activities will
be exacerbated by climate change impacts on the Arctic that are already stressing
those species.
Eighth Circuit.
In Mid States Coalition for Progress v. Surface Transportation Bd., 345 F.3d
520 (8th Cir. 2003), petitioners disputed the adequacy of an EIS prepared by the
Surface Transportation Board to accompany its approval of a railroad’s proposal to
construct new rail and upgrade existing rail. The proposed rail line was to provide
a less expensive route by which low-sulfur coal in Wyoming’s Powder River Basin
could reach powerplants, and thus might be expected to increase coal consumption
and its attendant effects. In this regard, the court noted that CEQ’s NEPA regulations
require that EISs cover both direct and indirect effects of proposed actions.83 It
concluded by finding it “irresponsible” for the Board to approve such a large project
without first examining the possible effects of an increase in coal consumption —
apparently, the opinion suggests (but does not explicitly say), including climate
change. 84
In Ranchers Cattlemen Action Legal Fund v. Conner, No. 07-CV-01023 (D.S.D.
filed October 24, 2007), plaintiffs challenge Department of Agriculture regulations
easing restrictions on the import of live cattle and edible bovine products from
“minimal risk” Mad Cow Disease regions (Canada). Plaintiffs assert that the
environmental assessment was inadequate because it did not analyze the increased
GHG emissions from the transportation of the cattle into the United States.
State NEPAs.
A few GHG-related suits also have been filed under state “little NEPAs” —
state laws requiring state (and sometimes local) agencies to consider the
environmental impacts of their proposed actions, just as the federal NEPA does for85
federal agencies. For example, in General Motors Corp. v. California Air
Resources Bd., No. 05-02787 (Cal. Sup. Ct. filed September 2, 2005), two car
manufacturers claimed that the Board’s adoption of California’s GHG emission
standards involved delayed and inadequate compliance with the state’s NEPA-type
law. This suit offers as a prime reason for environmental analysis the argument that
GHG emissions regulation has, in addition to a possible benefit, some environmental
downsides. In particular, it contends that restriction of GHG emissions may cause

an increase in new-vehicle sticker prices and a consequent decrease in the rate at
which old, higher-emissions vehicles are retired from use.
State-NEPA cases were filed in April, 2007 by conservation groups and the
California attorney general to require San Bernardino County, the largest county in
the United States by area, to address climate change in its General Plan update.86 In
August, 2007, California settled its lawsuit, the County agreeing to prepare a
Greenhouse Gas Emissions Reduction Plan and adopt other measures, but the
conservation groups’ suit remains. In broaching the vast realm of local land use
plans, these cases portend a major new front in climate change litigation, particularly
in states that require environmental impact analysis.
Global Change Research Act
The Global Change Research Act of 1990 (GCRA)87 commands the President
to create an interagency United States Global Change Research Program to improve
understanding of “global change.” Global change is defined broadly by the GCRA
to include all changes in the global environment “that may alter the capacity of the
Earth to sustain life.” Thus, the statute includes, but goes beyond, climate change.88
The Program is to be implemented by a National Global Change Research Plan, with
regular scientific assessments that evaluate the findings of the Program. The GCRA
demands that revised Research Plans be submitted to the Congress at least every
three years,89 with the last one having been submitted July, 2003. The statute further
demands that scientific assessments be submitted to the President and Congress not
less often than every four years,90 with the only assessment to date submitted
October, 2000.
On these undisputed facts, the district court in Center for Biological Diversity
v. Brennan, 2007 Westlaw 2408901 (N.D. Cal. August 21, 2007), had little difficulty
finding that the Administration had unlawfully withheld action it was required to
take. It ordered defendants to publish a summary of the revised proposed Research
Plan no later than March, 2008, with submission to Congress no later than 90 days
thereafter.91 The court further ordered the scientific assessment to be produced by
May, 2008. It should be noted in passing that the large bulk of this opinion is
devoted not to the foregoing violation and remedy, but to threshold matters: standing
(finding procedural rights injury and informational injury, associational standing, and
Administrative Procedure Act standing) and a motion to intervene by two Members
of Congress (denied).

Freedom of Information Act
The Freedom of Information Act (FOIA)92 mandates that documents in the
possession of federal executive branch agencies are to be disclosed to the public upon
request, unless covered by a FOIA exemption.
In May, 2006, Citizens for Responsibility and Ethics in Washington (CREW)
invoked FOIA to request from the Council on Environmental Quality (CEQ) all of
its records relating to the causes of climate change, from January 20, 2001, to
October 26, 2006. Though CEQ produced many documents, CREW sued under
FOIA seeking a court order that CEQ release all records responsive to its request.
Citizens for Responsibility and Ethics in Washington v. Council on Environmental
Quality, No. 1:07CV00365 (D.D.C. filed February 20, 2007). In a fall 2007 filing
with the court, the parties noted that CEQ had produced 16,000 pages of documents
to CREW by May, 2007, and was about halfway through processing the remaining

27,000 pages.93


This lawsuit parallels allegations that political appointees at CEQ have edited
many of the agency’s reports to minimize the danger and human causes of climate
change. In July, 2006, the House Committee on Government Reform94 requested that
CEQ provide documents and communications relating to the agency’s edits of
climate change materials, its efforts to influence the statements of government
scientists, its communications with federal agencies and nongovernmental parties
regarding climate change, and so on.
V. Common Law Tort
The widely diverse injuries predicted from climate change mean that a
comparably diverse spectrum of plaintiffs and defendants could become involved in
common law tort litigation based on such injuries. Possible plaintiffs include
property owners (farmers dealing with reduced rainfall, owners of oceanfront homes
dealing with rising sea level or increased storm activity), nonowner users of natural
resources (ski resort operators, commercial fishermen), and state attorneys general
bringing private or public nuisance claims (the former for injury to state-owned land,
the latter on behalf of the state’s citizenry to protect public health and well-being).
Possible defendants include the companies that produce the fossil fuels whose
combustion produces GHG emissions, entities that emit GHGs (chiefly fossil-fuel-
fired powerplants, but many other sources also), and companies that manufacture or
market products whose use creates GHG emissions (chiefly the automakers).95

James Salzman, Negligence in the Air: The Duty of Care in Climate Change Litigation, 155
(continued...)

Several of these potential plaintiff and defendant categories are represented in
the five climate-change-related tort cases known to be filed thus far (four discussed
in the following text, one in footnote 105). Thus far, all of those tort actions that
have produced court decisions have failed, either due to lack of standing or the
political question doctrine, or both. Three are on appeal, however.
Nuisance
In 2004, eight states (CA, CT, IA, NJ, NY, RI, VT, WI) and New York City
sued five electric utility companies.96 Connecticut v. American Electric Power Co.,
Civ. No. 04 CV 05669 (S.D.N.Y. filed July 21, 2004). These defendants were chosen
as allegedly the five largest CO2 emitters in the United States, through their fossil-
fuel-fired electric powerplants. Invoking the federal and state common law of public
nuisance,97 plaintiffs seek an injunction requiring defendants to abate their
contribution to the nuisance of climate change by capping CO2 emissions and then
reducing them. Plaintiffs sue both on their own behalf to protect state-owned
property (e.g., the hardwood forests of the Adirondack Park in New York), and as
parens patriae on behalf of their citizens and residents to protect public health and
well-being.
On the same day, three nongovernmental organizations filed a similar suit
against the same defendants, in the same court, adding a private nuisance claim.98
Open Space Institute v. American Electric Power Co., No. 04 CV 05670 (S.D.N.Y.
filed July 21, 2004). They seek to protect land owned and preserved by them in the
state of New York.99 This suit was consolidated with the state suit.
In a series of motions, defendants sought to have these actions dismissed on a
wide spectrum of threshold grounds. Though the case has now been decided by the
trial court on a single threshold issue, it is worth reviewing the grounds advanced in
these motions because they may reappear later, in this or other private GHG

litigation.100 To reiterate, many of these grounds typify the difficulties encountered
when one seeks to address through private litigation a ubiquitous, long-term
environmental problem to which countless parties contribute.
In a dismissal motion, some defendants argued there is no federal common law
cause of action for climate change. Creating such federal common law, they argued,
runs afoul of Supreme Court directives that federal courts do so only in limited areas
— especially where, as with climate change, the problem at issue has sweeping
implications. Even assuming a viable federal common-law nuisance theory, they
continued, Congress’s enactment of a comprehensive scheme of air pollution
regulation in the CAA displaces federal court authority in this area. Defendants also
challenge plaintiffs’ standing to sue. Plaintiffs, they argued, have not demonstrated
the “injury in fact” requisite of standing because they allege only injuries from
climate change in the indefinite future. Nor, said these defendants, have plaintiffs
shown “causation” because they do not allege that defendants’ conduct will directly
cause the consequences of climate change — especially since defendants’ collective
emissions are admitted to be less than 2-1/2% of the global total from human
activities.101 As mentioned, the viability of these federal common law of nuisance
and no-standing arguments by defendants may be significantly affected — the
displacement argument helped, the others hurt — by Massachusetts v. EPA.
A second motion sought dismissal for lack of personal jurisdiction. These
movants alleged that although their powerplants are located in 20 states, none is in
New York (where the case was filed) or any other plaintiff state except Wisconsin.
A final motion to dismiss asserted that to the limited extent a federal common
law claim to abate an interstate nuisance has been recognized, it has been limited to
actions brought by state entities. Nor, said defendants, can plaintiffs assert public
nuisance, because they have not alleged special injury to their properties, or private
nuisance, because they have not alleged substantial harm.
As indicated, the dismissal motions in Connecticut and Open Space Institute
have now been ruled on by the district court,102 which dismissed the cases on political
question grounds. This judicial doctrine requires a court to look into “the
appropriateness under our system of government of attributing finality to the action
of the political departments [i.e., the legislative and executive branches] and also the
lack of satisfactory criteria for a judicial determination....”103 One situation judicially
recognized as pointing to a political question, hence dismissal of the action, is “the
impossibility of deciding [the case] without an initial policy determination of a kind


100 See generally Thomas W. Merrill, Global Warming as a Public Nuisance, 30 Colum. J.
Envtl. L. 293 (2005) (discussing threshold hurdles of standing, the applicability of federal
common law, and foreign policy preemption).
101 An interesting question raised by the Prof. Merrill article, supra note 100, is whether
these general standing requirements, developed in the context of private lawsuits, should
apply in a suit such as State of Connecticut — that is, in a parens patriae suit brought by
state attorneys general under public nuisance law.

clearly for nonjudicial discretion.”104 This situation, said the court, perfectly fit the
GHG cases, touching as they do on so many areas of national and international
policy. As a political question, the court believed the climate change issue in these
suits to be for the legislature, not the courts, to resolve. Very possibly, the
amorphousness of nuisance law, giving the court little guidance in resolving these
cases, may have hurt the plaintiffs’ cause. (These cases are now on appeal to the
Second Circuit.105)
A second nuisance action was filed in 2006 by California against several
automobile manufacturers based on the alleged contributions of their vehicles to
climate change impacts in the state. The suit alleges that these impacts constitute a
public nuisance under federal or state common law, and seeks monetary damages
(plaintiffs in Connecticut seek injunctive relief). The district court dismissed the suit
on the same political-question rationale as in Connecticut — namely, “the
impossibility of deciding without an initial policy determination of a kind clearly for
nonjudicial discretion.” California v. General Motors Corp., 2007 Westlaw 2726871
(N.D. Cal. September 17, 2007). The need for an “initial policy determination” by
the political branches was supported, in the court’s view, by the complexity of the
climate change issue, the need for political guidance in divining what is an
“unreasonable” interference with the public’s rights (the definition of a public
nuisance), and the existing debate over global warming in the political branches.
Ironically, the environmental “win” in Massachusetts v. EPA was cited by the court
against the state, both because that decision found authority over GHG emissions to
lie with the federal government and because it recognized a state’s standing to press
its grievances at the federal level. (An appeal to the Ninth Circuit is pending.)
Most recently, a native village on the Alaska coast sued certain oil and energy
companies, claiming that climate change is destroying the village through the melting
of Arctic sea ice that formerly protected it from winter storms. Native Village of
Kivalina v. Exxonmobil Corp., No. 08-cv-01138 (N.D. Cal. filed February 26, 2008).
Indeed, the complaint asserts, “[t]he U.S. Army Corps of Engineers and U.S.
Government Accountability Office have both concluded that the village must be
relocated due to global warming....” The village invokes the federal common law of
public nuisance, state statutory or common law of private and public nuisance, and
a civil conspiracy claim. The conspiracy claim asserts that some of the defendants
have engaged in agreements to participate in the intentional creation or maintenance
of a public nuisance — that is, global warming — by misleading the public as to the
science of global warming.


104 Id. at 217.
105 Presumably two of the plaintiffs, New York State and New York City, have been able to
support their standing to sue by arguments not contrary to those they made against plaintiff
standing in another public-nuisance climate change case in which they were the defendants.
Avoiding contradictory arguments was presumably facilitated by the idiosyncratic nature
of the global-warming harms alleged by the pro se plaintiff — e.g., those based on plaintiff’s
enhanced vulnerability to disease-causing pollution as compared to the general population.
According to the court, plaintiff appeared to be requesting an injunction ordering the
defendants to stop polluting and use his invention for reducing carbon dioxide emissions.
Korsinsky v. U.S. EPA, 192 Fed. Appx. 171 (2d Cir. 2006) (affirming district court
dismissal based on lack of standing).

Negligence, etc.
Owners of Mississippi property damaged by Hurricane Katrina sued certain oil,
coal, and chemical companies, alleging a multistep chain of causation: the companies
emitted GHGs, which contributed to global warming, which made the waters of the
Gulf of Mexico warmer, which caused Hurricane Katrina to become more intense as
it passed over the Gulf than it would otherwise have been, which increased the harm
to plaintiffs’ property caused by the hurricane. Plaintiffs asserted various state-law
tort claims, including negligence, nuisance (public and private), and trespass, and
seek compensatory damages; they request punitive damages for gross negligence.
Further, they claimed fraud and conspiracy to commit fraud, alleging that the oil and
coal companies disseminated misinformation about global warming. Finally,
plaintiffs made claims against their home insurance companies (e.g., breach of
fiduciary duty claim for misrepresenting policy coverage, and violation of a state
consumer-protection act) and their mortgage companies (arguing that they may not
claim sums owed by plaintiffs for the value of the mortgaged property that was
uninsured).
The district court, sitting in diversity, dismissed the action for lack of plaintiff
standing. Comer v. Murphy Oil USA, Inc., Civ. Action No. 1:05-CV-436-LG-RHW
(S.D. Miss. August 30, 2007). With regard to certain defendants, the court also
found plaintiffs’ claims nonjusticiable under the political question doctrine — as in
the decisions above where nuisance was the sole legal theory advanced. (An appeal
to the Fifth Circuit is pending.)
VI. Federal Preemption
Stationary Sources of GHG Emissions
The question of whether federal law preempts state regulation of GHG
emissions arises chiefly in connection with mobile sources. With limited exceptions,
the CAA disclaims any intention to preempt state air pollution controls on stationary
sources.106 And the Energy Policy and Conservation Act does not set fuel economy
standards for other than mobile sources, so it too would be unlikely to preempt state
regulation of stationary sources. However, some have asserted that state regulation
of stationary-source GHGs is preempted as contrary to the federal government’s
authority over foreign policy — an argument being pressed, so far unsuccessfully, in
litigation attacking state regulation of mobile-source GHG emissions (see below).
The most prominent state enactment limiting GHG emissions from stationary sources
is that of California, which so far has not been challenged.107


106 CAA § 116, 42 U.S.C. § 7416. The exceptions in this nonpreemption provision say that
states may not adopt emission limitations for stationary sources that are less stringent than
those in state implementation plans, new source performance standards, or national emission
standards for hazardous air pollutants.
107 See Global Warming Solutions Act of 2006, A.B. 32, Cal. Health & Safety Code §
38500 et seq. This law requires that GHG emission limits be in effect in California by 2012
(continued...)

Mobile Sources of GHG Emissions: CAA Preemption
The picture is quite different for mobile sources, where preemption is the
general rule. The CAA preempts states from adopting any “standard relating to the
control of emissions from new motor vehicles ...”108 and the act defines “emission
standard” as certain limits on “emissions of air pollutants.”109 The Supreme Court
has now held that at least for purposes of mobile sources, “air pollutants” includes
GHGs. Thus, CAA preemption of state regulation of car and truck GHG emissions
is clear, whether or not EPA proceeds to regulate a particular mobile-source GHG.
It would seem, then, that states are preempted from setting emission standards for
CO2, methane, and hydrofluorocarbons — three substances said to enhance climate
change — even though EPA has not set mobile-source emission standards for them.
An exception to the general CAA rule preempting state mobile-source emission
regulation is that EPA may waive CAA preemption for one particular state,
California, if that state requests a waiver.110 Further, when EPA does grant California
a waiver, the act automatically extends it to almost all states with mobile-source
emission limits identical to California’s.111
Under this “California waiver” authority, California requested a preemption
waiver for its GHG emissions regulations on December 21, 2005. These regulations
had been promulgated under a 2002 California enactment that was the first in the
nation to call for limits on GHG emissions from mobile sources. Assembly Bill
1493112 instructs the California Air Resources Board (CARB) to adopt regulations
that achieve the maximum feasible reduction of GHGs emitted by passenger vehicles
and light-duty trucks. The CARB adopted the required regulations in 2004. The
regulations target CO2, methane, nitrous oxide, and hydrofluorocarbon emissions,
setting “fleet average greenhouse gas exhaust mass emission requirements for


107 (...continued)
to reduce statewide GHG emissions to the 1990 level by 2020. Note, however, that although
A.B. 32 applies chiefly to stationary sources, it provides that if the mobile source GHG
emission limits imposed by an earlier state enactment are struck down, “alternative
regulations” to restrict mobile-source GHG emissions shall be imposed under A.B. 32. As
the following paragraphs of the text discuss, this earlier enactment is now the subject of a
preemption challenge.
108 CAA § 209(a), 42 U.S.C. § 7543(a).
109 CAA § 302(k), 42 U.S.C. § 7602(k). Emphasis added.
110 CAA § 209(b), 42 U.S.C. § 7543(b). Under section 209(b), EPA “shall” grant the waiver
“if the State determines that the State standards will be, in the aggregate, at least as
protective of public health and welfare as applicable federal standards.” However, no
waiver shall be granted if EPA finds that the state’s determination is arbitrary and
capricious, the state does not need the standards to meet “compelling and extraordinary
conditions,” or the state standards and accompanying enforcement procedures are
inconsistent with CAA section 202(a).
111 CAA § 177, 42 U.S.C. § 7507. Section 177 limits its extension of the section 209 waiver
to those states that have approved nonattainment-area plans. This includes all states except
North Dakota, South Dakota, and Hawaii.
112 Cal. Heath & Safety Code § 43018.5.

passenger car, light-duty truck, and medium-duty passenger vehicle weight classes.”
The first model year to which the fleet averages apply is 2009. The averages are
reduced for each subsequent model year through 2016.
On December 19, 2007, almost two years after California requested the waiver,
the EPA Administrator wrote the California governor that he intended to deny the
state’s request. On January 3, 2008, two petitions for review of this letter, arguing
that it constituted final agency action on the waiver request, were filed in the Ninth
Circuit. One suit was filed by California, with 18 other states intervening on
California’s side. The other suit was filed by environmental groups, and was
consolidated with the first. However, since then, on February 29, 2008, the EPA
Administrator signed a decision document formally announcing the waiver denial,113
rendering unclear what will happen to the January 3 filings, which, again, are based
on an argument that the letter is the reviewable agency action.114 Presumably a new
petition for review will be filed by the same or similar parties in connection with the
formal decision document.115
Mobile Sources of GHG Emissions: Non-CAA Preemption
That the CAA preempts state GHG regulation of mobile sources cannot be
seriously questioned, absent a California waiver. The following preemption litigation
is significant for the non-CAA preemption claims being pressed. If successful, these
claims would prevent California and other states from implementing the California
mobile-source standards even if EPA’s denial of the waiver is judicially reversed.
Non-CAA preemption suits, brought by auto interests, are pending in four of the
federal judicial circuits containing a state that has adopted GHG controls on vehicles.
Two decisions have been handed down, from Vermont (First Circuit) and California
(Ninth Circuit). Both reject the non-CAA preemption theories presented.
In the first to be decided, Green Mountain Chrysler Plymouth Dodge v.
Crombie, 508 F. Supp. 2d 295 (D. Vt. 2007), the court ruled that the relationship
between Vermont’s (California-identical) GHG standards and EPCA was better
analyzed as an interplay between two federal statutes, rather than as a federal
preemption question. So viewed, the court pointed out that the National Highway
Traffic Safety Administration (NHTSA) has consistently treated EPA-approved
California mobile source emissions standards as constituting “other motor vehicle
standards of the Government,” which EPCA says NHTSA must consider when
setting CAFE standards.116 Moreover, in a related context the Massachusetts v. EPA


113 73 Fed. Reg. 12156 (March 6, 2008).
114 It is not unclear, however, what will happen to California’s November, 2007, suit asking
the court to order EPA to issue its waiver decision forthwith. This suit is plainly moot now.
115 See generally California’s Waiver Request to Control Greenhouse Gases Under the
Clean Air Act, CRS Report RL34099, by James E. McCarthy and Robert Meltz.
116 49 U.S.C. § 32902(f).

decision saw the EPCA CAFE provisions as harmonious with the CAA.117 Thus, the
court found the relationship between the CAA waiver authority and the EPCA CAFE
provisions to be one of overlap, but not conflict. Despite its conclusion that
preemption doctrine did not apply, the court did a preemption analysis anyway,
finding that Vermont’s GHG standards were preempted neither by EPCA nor as an
intrusion upon the foreign policy authority of the United States.118
In the second decision, Central Valley Chrysler-Jeep, Inc. v. Goldstene, 529 F.
Supp. 2d 1151 (E.D. Cal. 2007), a district court similarly rejected claims that
California’s first-in-the-nation GHG emission regulations were precluded by EPCA,
preempted by EPCA, or preempted as an intrusion of state law on federal authority
to conduct foreign affairs.
The legal theories pressed in the Crombie and Goldstene litigation are replicated
in two Rhode Island suits — Lincoln Dodge, Inc. v. Sullivan, No. 1:06-CV-00070
(D.R.I. filed February 13, 2006), and Association of International Automobile
Manufacturers v. Sullivan, No. 1:06-CV-00069 (D.R.I. filed February 13, 2006) —
challenging that state’s adoption of the California standards. Most recently, New
Mexico’s adoption of the California GHG standards has been challenged as
preempted under EPCA in Zangara Dodge, Inc. v. Curry, No. 1:07-CV-01305
(D.N.M. filed December 27, 2007).
VII. State Utility Laws
In 2000, the City of Seattle adopted a goal of meeting its electricity needs with
“no net greenhouse gas emissions.” To achieve this goal, the city ordered the city-
owned electric utility to offset its GHG emissions by paying others to reduce their
GHG emissions. The utility did so, largely through agreements paying other entities
to use cleaner fuels. This made the utility (according to its press release) “the first
large electric utility in the country to effectively eliminate its contribution of harmful
greenhouse gas emissions.” In Okeson v. City of Seattle, 150 P.3d 556 (Wash. 2007)
(en banc), however, the utility’s ratepayers argued that this offset arrangement was
not authorized by the state’s utility enabling act. The Washington Supreme Court
agreed, explaining that the purchase of GHG offsets was not impliedly authorized by
the enabling act in that the offset contracts were not proprietary because they were
not part of the services for which ratepayers are billed, nor were they within the
enabling act’s purposes.
In another case, In re Otter Tail Power Co., 744 N.W.2d 594 (S.D. 2008),
environmental intervenors urged the state public utilities commission to deny a
permit to build a coal-fired energy conversion facility, in light of the substantial CO2
it would emit. Notwithstanding, the commission granted the permit, and the state
supreme court sustained. The commission, it held, was not clearly erroneous in
finding that the added CO2 threatened no “serious” injury to the environment, the
state’s statutory standard. Deference to the commission was particularly appropriate,

it said, because the CO2 from the plant would increase national CO2 emissions by
only .07%, and neither Congress nor the state had chosen to regulate CO2 emissions.
VIII. International Law
Could the United States, as a major GHG emitter that has declined to participate
in the Kyoto Protocol, be sued in international forums for the adverse effects of
climate change? Gauging the viability of such claims against the United States
involves a good deal of guesswork, as they lie on the frontiers of international law.
This report, concerned primarily with actually filed claims, notes only a few
highlights, taken mostly from what appears to be the most pertinent article in the
area.119 The article suggests that the International Court of Justice (ICJ) might be one
forum for resolution of climate change claims, with jurisdiction established through
treaties that specifically provide for dispute resolution before the court. A problem
with the ICJ approach is that the treaties most likely to be invoked are Friendship,
Commerce, and Navigation or similar treaties, which focus on how each party within
its own country treats the other country’s nationals and property. A climate change
suit, by contrast, likely would have an extraterritorial focus. Another ICJ possibility
would be for the court to render an advisory opinion, at the request of a body
authorized under the U.N. Charter to request one.
Other possibilities include voluntary submission of a climate change dispute to
any of several international arbitral forums or resort to the specialized dispute
resolution systems created under various treaties. An example of the latter,
reportedly being actively considered, is a fisheries conservation agreement under the
UN Law of the Sea Convention, presumably on the argument that increased ocean120
temperatures from climate change imperil certain fish stocks.
Some principles that might be applied to a claim alleging GHG-caused injury
might be taken from the international law of transboundary pollution. For example,
the Restatement (Third) of Foreign Relations Law describes an international law
principle under which a nation must “take such measures as may be necessary, to the
extent practicable under the circumstances, to ensure that activities within its
jurisdiction or control ... are conducted so as not to cause significant injury to the121
environment of another state....” Similarly, the Trail Smelter arbitration decision,

probably the seminal ruling on state liability for transboundary pollution, declared
that “[a] State owes at all times a duty to protect other States against injurious acts
by individuals from within its jurisdiction.”122 Of course, as with the domestic
common law litigation described in Section V, daunting hurdles confront the
claimant in making the link between climate change in general and specific
environmental harms, and in apportioning how much of such harms are attributable
to the charged party or parties, in this instance the United States.
A widely noted international-law action was filed by a group based in the Arctic,
where the temperature rise from climate change has been among the fastest. In 2005,
the Chair of the Inuit Circumpolar Conference, on behalf of herself and all affected
Inuit of the arctic regions of the United States and Canada, filed a petition against the
United States with the Inter-American Commission on Human Rights, the
investigative arm of the Organization of American States (OAS).123 The petition
alleged that the United States, through its failure to restrict its GHG emissions and
the resultant climate change, has violated the Inuit’s human rights — including their
rights to their culture, to property, to the preservation of health, life, and physical
integrity, and so on.124 Inuit culture is described in the petition as “inseparable from
the condition of [its] physical surroundings.” Generally, the Inter-American
Commission on Human Rights is empowered to recommend measures that contribute
to human rights protection, request states in urgent cases to adopt specific
precautionary measures to avoid serious harm to human rights, or submit cases to the
Inter-American Court of Human Rights. The United States, however, has not
accepted the jurisdiction of this court, so the Inuit petition sought only to have the
Commission prepare a report declaring the responsibilities of the United States and
recommending corrective measures.
In 2006, the Inuit petition was rejected, with no reasons given (as is customary
for the Commission). However, at the request of petitioners the Commission held
a hearing on March 1, 2007 on the generic issue of climate change and human rights.
One may speculate that the Commission felt more comfortable with the hearing
format than the petition because the former did not single out the United States. Or
that the Commission was concerned the petition took it into a realm of global scale,
orders of magnitude vaster than the typical human rights petition it receives.
In 2005/2006, five petitions were submitted to the Intergovernmental Committee
for the Protection of the Cultural and Natural Heritage of Outstanding Universal
Value (World Heritage Committee), part of UNESCO.125 The petitions request that
various designated World Heritage Sites be placed on the List of World Heritage in

petitions are Waterton-Glacier International Peace Park (U.S./Canada), Sagarmatha
National Park (Nepal), Belize Barrier Reef Reserve System (Belize), Huascaran
National Park (Peru), and the Great Barrier Reef (Australia). Only the Waterton-
Glacier petition was filed by entities within the United States (12 environmental
groups) and involves a natural resource within the United States. As a party to the
World Heritage Convention, the United States is obligated to “do all it can ... to the
utmost of its own resources and, where appropriate, with any international assistance
and cooperation” to protect its cultural and natural heritage.127
In 2006, the World Heritage Committee acknowledged the five petitions but
appeared desirous of shifting the debate toward the use of existing committee
mechanisms at individual sites to adapt to the threat of climate change.128
IX. Comments
Gauging the prospects of the pending climate change lawsuits is a precarious
venture; for many of the suits, there is little precedent. It is clear, however, that
success in the conventional sense — obtaining a judgment for the environmental
plaintiff — is not the only objective of many of these suits. Some of the climate
change litigation almost certainly has a long-range strategic purpose — to keep
climate change on the political front burner and make it difficult for government and
GHG emitters to ignore the problem.
In the conventional sense of the term, plaintiffs’ successes have been rare in
cases seeking relief directly from GHG emitters. A court may be reluctant to impose
expensive measures to address a global problem on a defendant that is a
proportionately minor contributor (which almost all defendants are, given the vast
number of GHG emitters), using statutory provisions or common law principles that
were not formulated with global problems in mind, against a backdrop of scientific
uncertainty as to the precise consequences (if not the general cause) of climate
change. By contrast, the environmental side recently has scored major wins where
governmental remedies were sought. In a much-publicized string of 2007 decisions

policy authority of the United States,131 and NEPA,132 courts have shown increased
willingness to authorize or require government consideration of climate change.
As this report shows, standing has been a persistent issue for environmental
plaintiffs, though of late the tide appears to be shifting in their favor. And at least
for states, the Supreme Court decision in Massachusetts v. EPA is likely to work a
sea change in improving plaintiffs’ prospects. As noted earlier, the big question is
the extent to which the Supreme Court decision finding standing will be seen by the
lower courts to generalize to nonstate plaintiffs, other statutory and common law
contexts, and injuries (as from weather events) not as clearly attributable to climate
change as Massachusetts’s loss of shore land.
Causation is not only a component of the threshold standing test but a
component of the plaintiff’s case on the merits. Several writers have identified proof
of causation as a key obstacle to a tort action seeking relief from climate change
injury.133 And at the remedy stage, allocation of damages among specific defendants
will likely present both factual and legal challenges.
In either the standing or case-in-chief contexts, the climate change issues in
private-remedy actions reprise an intractable problem in environmental law:
imposing liability for harms that are remote in time and place from the pollution
sought to be abated, particularly where the pollution comes from multiple sources.134
Lawmakers of yesteryear encountered this same redistributive conundrum in tackling
the problem of acid rain, where pollution cause and effect are separated by hundreds
of miles and weeks or months. Imposing liability for harm from exposure to toxic
chemicals is of the same ilk: exposure to contamination from multiple sources may
result in ill effects manifested only a decade or two later.
Perhaps because of these hurdles under existing law, and the resistance of the
current Administration to regulatory approaches to climate change, new directions
are now being explored.135 Within the United States, several states have adopted their
own GHG emission controls, citing, among other things, inaction at the federal
level.136 Twenty-three states have joined one of the three regional GHG reduction
initiatives (Western Climate Initiative, Midwestern Regional Greenhouse Gas

Reduction Accord, and in the eastern states, Regional Greenhouse Gas Initiative).
Some states have explored the idea of emissions trading with Europe.137 Use of the
shareholder proposal process and SEC disclosure requirements have been suggested
as ways of forcing the issue in the corporate world.138 More loosely, 31 states and
two Canadian provinces announced in May 2007 the formation of a Climate Registry
to track greenhouse gas emissions from major industries, with independent
verification of data. California and the United Kingdom signed an agreement on July
31, 2006, committing both parties to implement market-based mechanisms, to share
results from studies to quantify the economic impacts of climate change, collaborate
on research, etc.139 Also internationally, this report noted the unsuccessful Inuit
petition filed with the Inter-American Commission on Human Rights and the pending
petitions before the World Heritage Committee. Reportedly, the low-lying Pacific
nation of Tuvalu threatened to sue the United States and Australia four years ago in
the ICJ, but held off for unspecified reasons.140
Whether these new paths will yield results, only time will tell. It is clear,
however, that if there is to be a government response to climate change at all, a
solution from the political branches is more likely to be comprehensive and fully
reflective of societal priorities than the typically narrowly targeted results of
litigation. Many proponents of litigation or unilateral state action freely concede that
such initiatives are make-do efforts that, while making a small contribution to
mitigating climate change, are also aimed at prodding the national government to act.
