have a legitimate moral claim, and failure to safeguard it amounts to generational
theft. Moreover, on the political level, by deļ¬ning the atmosphere as common
property, the trust positions all nations of the world in a logical relationship toward
each other and toward Nature.119 The trust framework deļ¬nes respective sovereign
obligations in quantiļ¬able, straightforward terms.120 Once presented in U.S. courts,
citizen litigants of other countries may invoke the trust concept. India, for exam-
ple, already has a robust public trust doctrine that citizens there can draw upon to
establish atmospheric trust responsibility.121 In short, by deļ¬ning the trust paradigm
of sovereign obligation in a litigation venue, courts may play a tremendous role in
harnessing the collective momentum from various other realms in which a paradigm
shift is necessary and already taking place.
Atmospheric trust litigation challenges lawyers and judges to take fundamental
principles of public trust law and apply them in coherent fashion to a new and
urgent context so as to arrive at a uniform, quantiļ¬able measure of governmental
responsibility to reduce carbon. The task is made easier by the fact that these
principles are logical, compelling, and seemingly applicable to all governments.

thinkers across the world are calling for new, innovative technologies and practices to
address climate crisis, lawyers should pioneer promising, if untested, legal constructs
to address carbon loading of the atmosphere. If one thing is clear, it is that the
body of statutory environmental law is a product of an altogether different era,
formulated to respond to circumstances far less urgent, less dangerous, and less
encompassing than those now confronting society. The environmental statutes were
not crafted to address a planetary emergency.122 The trust claim deļ¬nes a binding

engagement with the science of global warming but also provides a window into one
of the greatest obstacles to effective regulatory approaches to the problem of climate
change, which the Obama administration must grapple with as it embarks upon
its ambitious climate and energy initiatives. Namely, greenhouse gas emissions and
their impacts are foundationally multiscalar; they range from the most individual to
Referencing climate change as a multiscalar problem, however, only serves as a
starting point for further discussion. āScaleā is a complex and contested concept in
both the geography and the ecology literatures. Geographers have deļ¬ned it as (1)
āa nested hierarchy of bounded spaces of differing sizeā; (2) āthe level of geograph-
ical resolution at which a given phenomenon is thought of, acted on or studiedā;
(3) āthe geographical organizer and expression of collective social actionā; and
(4) āthe geographical resolution of contradictory processes of competition and
cooperation.ā3 Ecologists supplement this understanding with additional concepts.
They deļ¬ne scale as being composed of grain (āthe ļ¬nest level of spatial or temporal
resolution available within a given data setā) and extent (āthe size of the study area
or the duration of the studyā).4
This chapter analyzes the interaction of scale (in its many guises), science, and law
in the Supreme Court briefs, oral argument, opinion, and dissents in Massachusetts
v. EPA as a window into the complex dynamics at play in climate change litigation.
Its focus is not on the complexities of implementing the decision, another important
topic beyond the scope of this chapter, but rather on what can be learned from the
interactions that took place in this lawsuit. Formally, the case primarily occurs at a
national level; the parties dispute the interpretation of federal law in an action that
was heard by federal courts at every level. It is precisely this apparently ānationalā
character of the case, however, that makes it a good example of the multiscalar
dynamics of international decision making. Despite the formal federal level of
this case, both its actors and its arguments have subnational and supranational
dimensions that are deeply intertwined with the science of climate change.
Section 1 draws from Holly Doremusā™s work on the use of science as a tool
in, and an obstacle to, regulatory approaches and from Nathan Sayreā™s analysis of
the concept of scale to consider the particular challenges posed by the multiscalar
context of climate change. The section intertwines their theories to argue that both
sides in Massachusetts v. EPA use scientiļ¬c uncertainty together with the scale of the
problem to forward their version of appropriate regulation. Section 2 then supports
this argument through a detailed analysis of the interaction of scale, science, and law
in the briefs and opinions. Section 3 examines the implications of that interaction
for how this case should be ļ¬t into a model of international legal decision making

with respect to climate change. The chapter concludes with broader reļ¬‚ections on
strategies for improving the way in which courts engage the scale-science conļ¬‚uence.
1. THE SCALE-SCIENCE INTERSECTION AS AN
This section interweaves the work of two California-based academics: Holly Dore-
mus, a law professor whose scholarship explores the way in which science is used
in natural resource regulation,5 and Nathan F. Sayre, a geographer whose recent
scholarship has compared the analysis of scale in geography and ecology literatures.6
This section summarizes each of their approaches and then interweaves them in the
context of Massachusetts v. EPA.
1.1. Defensive Uses of Scientiļ¬c Uncertainty
Holly Doremusā™s article Science Plays Defense: Natural Resource Management in the
Bush Administration explains that the biggest difļ¬culty regarding science and politics
in natural resources management is not the politicization of science, but rather the
scientizing of politics. Both conservationists and those who seek to block regulation
can use science as a tool. Doremus notes: āThe combination of actual uncertainty
and public expectations of certainty makes the rhetoric of science equally available
to the regulatory offense and defense.ā7 She traces offensive and defensive uses of
science and then explores four main ways in which the Bush administration used
science defensively: high burden of proof, value choices in the face of ambiguity,

See Sayre, supra note 4. A substantial geography literature engages these questions of scale and
science. See, e.g., Louis Lebel, Po Garden & Masao Imamura, The Politics of Scale, Position, and
Place in the Governance of Water Resources in the Mekong Region, 10 Ecology & Socā™y 18 (2005);

eds., 2004). An extensive review of that literature is beyond the scope of this brief chapter, though I
plan to address it in more depth in future work. I choose to focus on Nathan Sayreā™s approach here,
however, because of the particular way in which he interweaves ecological and scalar issues.

resolution of scientiļ¬c certainty issues at the agency level, and limits to information
These offensive and defensive strategies around science are apparent in the debates
over climate change regulation in the United States. In fact, Doremus even quotes
a memorandum from communication professional Frank Luntz on the topic to
illustrate the defensive approach:
The most important principle in any discussion of global warming is your commit-
ment to sound science. Americans unanimously believe all environmental rules
and regulations should be based on sound science and common sense. Similarly,
our conļ¬dence in the ability of science and technology to solve our nationā™s ills is
second to none. Both perceptions will work in your favor if properly cultivated.9
If Luntz is correct, a reinforcement of current scientiļ¬c uncertainty and of the
importance of waiting for future technological and scientiļ¬c developments can
serve as a powerful tool in blocking more stringent regulation of greenhouse gas
Moreover, as Doremus has explained, in judicial decision making, the framing
of science is often outcome determinative.10 The climate change context is no
exception. The regulatory debates at the core of the arguments in Massachusetts v.
EPA, discussed in detail in Section 2, exemplify the offensive and defensive uses of
science that she has highlighted.
1.2. Debates over Scale
The arguments over science in Massachusetts v. EPA, however, consistently have
a particular geographic dimension to them: scale. Both the geography and the
ecology literatures, which engage scientiļ¬c issues very much interconnected with
climate change, have their own distinct discourses about scale. Sayreā™s recent article,
Ecological and Geographical Scale: Parallels and Potential for Integration, attempts
to interweave the two debates. He explains:
In both ecology and human geography, the adequacy of research at any single scale is
clearly in question, but the concept of scale itself remains unclear. Most participants
in the debates acknowledge the need for studies that span multiple scales, and most
conceive of different scales as being organized in some sort of hierarchical fashion.
Within human geography, recent contributions have established several further
points of general agreement: that scale is socially constructed and thus historically
contingent, that it is politically contested, and that it is centrally important to
understanding a variety of political, sociocultural, economic and environmental

phenomenon. The debate has foundered on basic conceptual and methodological
questions, however. What exactly is scale? How should researchers theorize and
He goes on to argue that human geographers should draw three primary lessons
from the ecologistsā™ work on scale: that it is critical to distinguish between scale and
level,12 that rescaling processes are about āshift[ing] the level at which some process
occursā within āan existing structure of social organization,ā13 and that hierarchical
models of scale can be misleading at times.14
Sayreā™s analysis of scale, like Doremusā™s discussion of the scientizing of politics, is
reļ¬‚ected in the arguments of Massachusetts v. EPA. As discussed in detail in Section
2, both sides consistently try to (1) rescale, that is, change the relevant level for the
argument, and (2) create hierarchies among levels ā“ that is, assert the primacy of a
particular level ā“ in order to accomplish their goal of proving the appropriateness
or inappropriateness of the EPA exercising its discretion to regulate motor vehicle
greenhouse gas emissions.
1.3. Scale as a Lens on Science and the Law
The key point of this chapter is not simply that both scientizing and rescaling
occur in this case, but rather that they are being used together to accomplish
litigative goals. The large scale ā“ both spatially and temporally ā“ of climate change,
and the resulting scientiļ¬c uncertainties about subnational contributions to it and
impacts from it, are combined by the respondents in an attempt to block regulatory
behavior. In contrast, petitioners assert the appropriateness of nation-level regulation
of supranational phenomenon and certainty around subnational contributions and
effects to try to push for EPA action.15
These dynamics suggest that offensive and defensive strategies around science
have particular nuances in multiscalar contexts in which relevant levels range from
the individual to the global. Namely, the existence of multiple levels to jump and
many possible arrangements of hierarchy allows for intersecting efforts at rescaling
that place judges in a particularly difļ¬cult decision-making position. Moreover,
the nexus of uncertainty around both science and scale creates additional judicial
discretion and opportunities for litigants to attempt to manipulate the outcome.16

See infra Section 2. As Holly Doremus has noted, the dynamics of this case represent only one variation
of the intersection of scale, science, and regulation. In other contexts, such as debates over critical
habitat, scaling down also can be an antiregulatory strategy because scientiļ¬c uncertainty is often
magniļ¬ed at smaller scales. E-mail from Holly Doremus, Professor, UC Davis School of Law, to Hari

2. THE COLLISION OF SCALE AND SCIENCE
IN MASSACHUSETTS V. EPA
Massachusetts v. EPA involves the appropriateness of the U.S. EPAā™s denial of a
petition requesting that it regulate motor vehiclesā™ greenhouse gas emissions under
section 202(a)(1) of the Clean Air Act.17 The case is just one of many petitions and
lawsuits engaging global climate change that have been ļ¬led around the world in
subnational, national, and supranational fora. These litigative efforts tend to take
two main approaches: (1) claims against governmental entities to force or limit
regulatory behavior and (2) claims against corporate emitters to limit emissions
directly. Massachusetts v. EPA falls into the ļ¬rst category. In both forms, the cases
serve as part of state-corporate regulatory interactions around climate change.18
This Section explores the dynamics among scale, science, and law in the case. It
considers the scales represented by the petitioners and respondents in the case, the
use of science and scale in the claims by petitioners and respondents, and the implica-
tions of these approaches for efforts to use science as a tool for and against regulation.
The parties to Massachusetts v. EPA constitute a diverse group that cuts across
scales. Twelve states, three cities, a U.S. territory, and thirteen nongovernmental
organizations brought the petition. Ten other states and nineteen industry and
utility groups ā“ organized into six conglomerate entities ā“ and the U.S. EPA served

country. The national-level governmental respondent, the U.S. EPA, is based in
Washington, D.C., but has ten regional ofļ¬ces located in major cities throughout
the country; it thus engages national policy issues through interacting in multiple
places with various levels of government.20 The nongovernmental entities similarly
have a mix of local, state, national, and international ties.21 And the preceding lists
do not even include the many who ļ¬led amicus briefs or other actors engaged in
responding to the Supreme Courtā™s ruling.
From a scalar perspective, then, this case interacts with far more than simply the
federal level at which it occurs. The actors reveal Massachusetts v. EPA as a situs for
contestation across levels of governance between a wide variety of interested actors.
As I have analyzed elsewhere, these dynamics pose difļ¬cult questions about how
to locate this case in an analysis of transnational regulatory governance of climate
The facts in this case involve the U.S. EPAā™s denial of a national-level rulemaking
petition under a national-level law, the Clean Air Act, to address emissions by
vehicles in places around the United States. These localized emissions contribute to
the supranational phenomenon of climate change, which produces varying speciļ¬c
effects in particular places at a subnational level. The substantive and procedural
claims made by the petitioners rely upon national-level statutes to address a situation
that occurs across spatial and temporal scales. Moreover, this intersection of scalar
issues and scientiļ¬c data was at the core of both the standing and substantive issues
debated in the U.S. Supreme Court.
Although standing was not one of the issues initially before the court,23 the respon-
dents raised it in their brieļ¬ng and the Supreme Court justices discussed it

extensively in oral argument. The Brief of the Federal Respondent claimed that
the supranational and extended time scales of climate change limited the impact of
national-level decisions to limit reductions:
Global climate change is, by deļ¬nition, a global phenomenon. The greenhouse
gases at issue here are āfairly consistent in concentration, everywhere along the
surface of the earth.ā The vast majority ā“ as much as 80 percent ā“ of all greenhouse
gas emissions emanate from countries other than the United States. For that reason,
reducing greenhouse gas emissions within the United States is unlikely, as a general
matter, to have a signiļ¬cant long-term impact on climatic conditions in this country
without reductions of greenhouse gas emissions in other parts of the world.24
The respondents further argue with respect to standing that the impacts at state
and local levels are too speculative because of the extent of both the space and
time involved. As the Brief for Respondents Alliance of Automobile Manufacturers,
Engine Manufacturers Association, National Automobile Dealers Association, and
the Truck Manufacturers Association (Brief for Respondents AAA) put it:
[B]ecause they do not face any imminent injury, petitioners are forced to rely on
predictions of harm decades in the future, the occurrence of which is largely (if
not entirely) dependent on actions other nations take in their own regulation of
greenhouse gas emissions. Petitionersā™ hypotheses, each of which is the subject
of an active scientiļ¬c debate, are reduced to conjecture by the inherent uncer-
tainty of global events that will unfold between now and the time of the predicted
These claims by respondents thus use scientiļ¬c uncertainty together with the alleged
global scale of the problem to argue against the appropriateness of the petitioners
being allowed to be before the Supreme Court.
The petitionersā™ reply to the standing argument rescales the issue back to the state
and local levels and the present time. They note:
Rising temperatures have injured petitioners in the following speciļ¬c and concrete
ways: coastal States have lost and are losing land to rising sea levels; ground-level
ozone (smog) is exacerbated by rising temperatures, leading to adverse health effects
and costly efforts on the part of States to address the problem; glaciers are melting,
causing distinct injuries to particular individuals. These injuries span a broad range,
from the Commonwealth of Massachusetts losing coastal land to Frank Keim no
longer being able to hike on the Alaskan glaciers he used to enjoy.
Petitionersā™ injuries are not āsome dayā injuries, as respondents contend; they
are injuries in the here and now. Nor do petitionersā™ declarations describe mere

āgeneralized grievancesā; they attest to harms being visited ā“ right now ā“ upon
particular individuals and particular States.26
This reply relies on the same scientiļ¬c data set but, by scaling down the argument,
engages the alleged injuries in ways that tie them more easily to legal standing
The Supreme Courtā™s opinion sides with the petitioners and indicates that the
āwidely sharedā character of climate-change risks does not prevent Massachusetts
from having an interest in the caseā™s outcome.27 It concludes the standing analysis:
In sum ā“ at least according to petitionersā™ uncontested afļ¬davits ā“ the rise in sea
levels associated with global warming has already harmed and will continue to
harm Massachusetts. The risk of catastrophic harm, though remote, is nevertheless
real. That risk would be reduced to some extent if petitioners received the relief
they seek. We therefore hold that petitioners have standing to challenge the EPAā™s
denial of their rulemaking petition.28
Although the Courtā™s holding on standing narrowly focuses on the interests of state
parties, its approach to them scales down the problem of climate change and its
regulation; this āglobalā phenomenon can cause harm at a state level and choices at
a federal level inļ¬‚uence the risks faced by states.
The dissenters, unsurprisingly, side with the respondents. Chief Justice Robertsā™s
dissent, for example, explains how, in his view, the multiscalar nature of the problem
The Courtā™s sleight-of-hand is in failing to link up the different elements of the
three-part standing test. What must be likely to be redressed is the particular injury
in fact. The injury the Court looks to is the asserted loss of land. The Court contends
that regulating domestic motor vehicle emissions will reduce carbon dioxide in the
atmosphere, and therefore redress Massachusettsā™s injury. But even if regulation
does reduce emissions ā“ to some indeterminate degree, given events elsewhere in
the world ā“ the Court never explains why that makes it likely that the injury in fact ā“
the loss of land ā“ will be redressed.29
In so doing, Chief Justice Roberts articulates his concerns about whether the occur-
rence of emissions around the world (essentially, local emissions taking place at a
global scale) makes the impact of U.S. national-level regulatory behavior less clear
at a subnational scale.
At the core of this battle over standing lies scientiļ¬c data. Both sides acknowledge
the problem of climate change, but they part ways in how to map the scientiļ¬c
information, and its uncertainties, onto existing legal structures. As emissions and
their impacts connect to multiple levels of governance, the parties and Court are

forced to grapple with how to apply the more simply structured standing doctrine to
2.2.2. Substantive Claims
The substantive arguments reveal a similar dynamic of scaling climate change and
regulatory authority over it up and down. For example, the respondents claim that
states cannot implement National Ambient Air Quality Standards (NAAQS) in this
context because their regulatory level fails to match the global level at which the
problem was occurring. The brief of respondent CO2 litigation group argues:
None of these regulatory authorities makes sense if the āair pollutantā to which they
are applied is CO2 or another greenhouse gas being regulated for the purpose of
mitigating potential global climate change. Since the projected effect of greenhouse
gas emissions is a function of changes in the global atmosphere, rather than local
or regional air quality, and it is the aggregate contribution of all greenhouse gas
emissions around the world to global atmospheric greenhouse gas contributions
that is believed by many to cause global climate change, notions of attaining or not
attaining an ambient air quality standard within a state or air quality control region
The theme of scientiļ¬c uncertainty is intertwined with the claim of scalar mis-
match, as represented in language like ābelieved by manyā in that statement. As
with the standing argument, respondents are portraying climate change as some-
thing occurring at a supranational level and over a long period of time with sub-
stantial deļ¬cits in current understanding about how anthropogenic greenhouse gas
emissions ļ¬t into that model.
The petitionersā™ argument on this point, in contrast, relies upon the various levels
at which the Clean Air Act provides regulatory authority. They note in their opening
Whatever question exists about the applicability of the NAAQS program to the air
pollutants at issue here cannot excuse the failure to adopt emission standards under
section 202. Section 202 does provide a perfectly feasible mechanism for regulating
emission of these pollutants from motor vehicles: the establishment of the same
sort of limits on these pollutants that EPA has already imposed on pollutants such
as carbon monoxide and hydrocarbons.31
In other words, regulation can work according to the petitioners if one changes
levels ā“ to the national one ā“ and type of regulatory approach.
A similar debate among the parties takes place over whether Congressā™s speciļ¬c
action with respect to ozone limits EPAā™s ability to regulate prior to a similar type of
action regarding global climate change. The Brief for Respondents AAA argues:

Congress has previously dealt with emissions issues relating to non-localized
gases that implicate global environmental concerns. For example, when Congress
addressed stratospheric ozone depletion it used an express delegation under a new
regulatory framework: Title VI of the Clean Air Act. The addition of Title VI to
address global issues reļ¬‚ects Congressā™s views about the regulatory limits of Titles I
and II of the Act.
Much like carbon dioxide, anthropogenic substances that deplete ozone are emitted
around the world and are very long-lived. Their upper-atmosphere ozone depleting
effects ā“ and the consequences of those effects ā“ occur on a global scale.32
This approach indicates a presumption that similarities in the scale and time frame of
two problems, as described in the existing scientiļ¬c literature, means that a Congres-
sional approach to one of them limits regulatory discretion with respect to another.
The petitioners, unsurprisingly, resist such an interpretation of the ozone
legislation. Beyond arguing that the ozone provisions have been used to regulate
āair pollutants associated with climate change,ā they note:
EPA cannot seriously maintain that ācoordination with the international commu-
nityā is a prerequisite for regulating pollutants that āare emitted around the world
and are very long-lived,ā the consequences of which āoccur on a global scale.ā
Congress directed EPA to regulate ozone-depleting substances themselves without
awaiting such coordination.33
The petitioners thus use the same analogy between ozone and global climate change
to indicate that national-level regulation of multiscalar problems is appropriate.
As with the standing issue, the majority opinion substantively sides with the
petitioners over a vigorous dissent. It holds that Clean Air Act section 202(a)(1), read
together with the Actā™s broad deļ¬nition of āair pollutant,ā gives the EPA statutory
authority to regulate greenhouse gas emissions from motor vehicles.34 Moreover, the
Court rejects the EPAā™s alternative argument that even if it has statutory authority, it
should not exercise it.35 In so doing, the opinion notes that the agency cannot avoid
its regulatory responsibilities simply by invoking scientiļ¬c uncertainty. Rather, the
EPA must address the statutory question of whether āsufļ¬cient information exists to
make an endangerment ļ¬nding.ā36
Although Chief Justice Robertsā™s dissent engages only the standing question,
Justice Scaliaā™s dissent ā“ joined by the other three dissenting judges ā“ addresses the
merits. Justice Scaliaā™s dissent begins by arguing that EPAā™s discretion is broader
than the majority holds,37 but then further indicates that the majority is wrong on

its own terms because of the EPAā™s statements on scientiļ¬c uncertainty.38 Its ļ¬nal
argument addresses scale even more clearly through arguing against the majorityā™s
broad interpretation of āair pollutant.ā39 In particular, the dissent focuses quite
literally on the question of the part of the atmosphere in which āpollutionā resides.
Because greenhouse gases build up in the upper atmosphere, the dissent claims that
the EPAā™s exclusion of them through focusing on āambient air at ground level or
near the surface of the earthā is statutorily consistent.40
Together, the actors and arguments in this case demonstrate the judicial chal-
lenge that the collision of scientiļ¬c uncertainty and multiscalar regulatory problems
poses. Although the parties used particular conceptions of that intersection in their
argument, the briefs and arguments are not explicit about the fact that the U.S.
Supreme Courtā™s selection of scalar perspective would inļ¬‚uence how the scientiļ¬c
data should be viewed. Similarly, choices about the scale of climate change and its
regulation run through the discourse among the majority and dissenting opinions,
but those decisions are often buried in the legal analysis.
3. IMPLICATIONS FOR INTERNATIONAL LEGAL DECISION MAKING
The strategic use of science with scale in Massachusetts v. EPA, especially when not
explicit, suggests dangers for the way in which decision making that has supranational
dimensions tends to be dichotomized. In particular, the Balkanization of both scalar
and identity categories allows for distorting efforts at rescaling. This section focuses
on three types of divisions that not only are inaccurate descriptors in a multiscalar,
multiactor framework but also provide the basis for the political games being played
in the case.
3.1. Domestic vs. International
Is Massachusetts v. EPA domestic or international?41 The case clearly was brought
under domestic law and many of the petitioners are domestic governmental actors,
but simply characterizing it as a domestic case does not encompass all of the scales
involved. As was repeatedly expressed by parties on both sides of the litigation, the
case involves a problem and broader law and policy discourse that have international

The Intersection of Scale, Science, and Law in Massachusetts v. EPA 141
Neither ādomesticā nor āinternationalā conveys fully the multiscalar character of
the case, and a notion that there is an appropriate regulatory level, either domestic
or international, fails to capture the many levels at which climate change must be
regulated. Moreover, the domestic/international distinction privileges the national
level at which the case is taking place by using it as the fulcrum point between
relevant categories. Using this dichotomy as a frame thus plays a distorting role in a
discourse over problems like climate change.43
3.2. Local vs. State vs. Federal
Similarly, if domestic, is Massachusetts v. EPA simply federal?44 The case was
brought in a federal court and involved the regulatory discretion of a federal actor, but
in both its actors and its claims, it involved many other scales and places associated
with them in the United States.45 After all, a good portion of the previously described
debate involved state and local actors, regulatory decisions, and impacts. Moreover,
the distinction ā“ local vs. state vs. federal ā“ fails to capture the nuances of the
levels involved or the fact that multiple levels are involved in every aspect of the
This point becomes even clearer if this case is viewed in the broader context
of climate change litigation and policy. For example, as I have discussed in depth
elsewhere,46 California is not only a plaintiff in Massachusetts v. EPA but also a
plaintiff or defendant in several other resolved and pending cases involving climate
change, some of which speciļ¬cally focus on motor vehicle emissions.47 Moreover,

The Intersection of Scale, Science, and Law in Massachusetts v. EPA 143
A mix of public and private actors appears on both sides of the lawsuit in Massa-
chusetts v. EPA, and in other instances of climate change litigation. Moreover, some
of the cases over vehicle emissions focus on governmental regulatory decisions, and
others focus on emissions decisions of private actors directly.52 To fail to see these
cases as involving a state-corporate regulatory dynamic would be just as ļ¬‚awed as
ignoring Californiaā™s critical role in the multiscalar dialogue about climate change.
As a wide range of actors operate across scales and play multidimensional roles
in the policy and lawmaking debate, Massachusetts v. EPA becomes one step in a
complex dance. This reality creates a risk that traditional ways of categorizing the
case ā“ which might focus on it as simply a public environmental regulatory dispute ā“
will miss critical elements of what it is.
4. CONCLUDING REFLECTIONS: STRATEGIES FOR MANAGING
The conļ¬‚uence of scale, science, and law in Massachusetts v. EPA does not simply
challenge our conventional approaches to categorization but also suggests important
strategies for managing these ever-more-common convergences better. In particu-
lar, the lack of explicit acknowledgment of battles at this intersection has trou-
bling implications for judicial decision making. When petitioners and respondents
are scaling up and scaling down without acknowledging it, judicial discretion is
increased tremendously. The scalar lens that the court chooses may well be outcome-
determinative and may not reļ¬‚ect a great deal of consciousness about the ways in
which the framing inļ¬‚uenced the decision.
Unfortunately, efforts to engage scale more directly may not actually ļ¬x this
problem. If parties spotlight the way in which scale and science are being used,
the court may make its decision more reļ¬‚ectively. However, the outcome will not
necessarily vary much. Judges may well choose the same scalar framing that they
were initially inclined toward selecting. As Holly Doremusā™s work makes clear, even
if scale and science are approached more consciously, the scientizing and scaling of
politics may be unavoidable.
Under such a view, explicit acknowledgment of the ways in which scale, science,
and law interact would simply change the words that advocates and judges use. Both
sides likely will continue to use scale and science in tandem both offensively and
defensively, and the arguments about why a particular framing is appropriate would
simply become more explicit and nuanced. Moreover, the lack of university-level
I have discussed this dynamic in depth in Osofsky, supra note 18, at 1796ā“97; see also Robert Dufresne,
The Opacity of Oil: Oil Corporations, Internal Violence, and International Law, 36 N.Y.U. J. Intā™l L.

peoplesā™ land rights, see Lillian Aponte Miranda, The Hybrid State-Corporate Enterprise and Violations

exposure to geography among many elites in the United States53 may cause resistance
to a deeper engagement of the nuances of scale and feed the politicization of its
conļ¬‚uence with science and law.
Even so, I think that an active effort to engage this intersection more systematically
would be an improvement over the status quo. When assumptions are allowed to
control discourse without conscious acknowledgment, the possibilities for political
manipulation of science are heightened. If courts and litigants engage the conļ¬‚uence
of law, scale, and science more thoughtfully, the potential for an adequate regulatory
discourse over complex issues like climate change improves. At the very least, an
explicit dialogue about these issues might help lawyers and judges become more
comfortable with the dynamics underlying cases like Massachusetts v. EPA. Given
the growing climate crisis and the Obama administrationā™s commitment to greater
federal regulatory efforts, which include rapidly responding to the Massachusetts v.
EPA decision, further exploration of these scalar questions is critical.54

Brendan R. Cummingsā— and Kassie R. Siegelā—ā—
On May 15, 2008, the U.S. Fish and Wildlife Service, an executive branch agency
within the Department of Interior, issued a regulation1 listing2 the polar bear under
the Endangered Species Act (ESA),3 a federal statute designed to prevent the extinc-
tion of imperiled plants and animals, due to global warming4 and the melting of the
bearā™s sea-ice habitat. This highly publicized milestone ļ¬rmly cemented the polar
bear as the iconic example of the devastating impacts of global warming on the
planetā™s biodiversity.5 While the polar bear is the most well-known species imperiled
by global warming, and the ļ¬rst to be listed under the ESA solely due to this factor, it
was not the ļ¬rst species protected under the statute in which global warming played
a signiļ¬cant role. Two years earlier, on May 9, 2006, the National Marine Fisheries
Service, declared two species of Caribbean coral Threatened under the ESA.6

The ESA has been declared by the U.S. Supreme Court to be āthe most compre-
hensive legislation for the preservation of endangered species ever enacted by any
nation.ā7 The statute is widely considered to be one of the strongest environmental
laws in the United States, and hence one of the most controversial.8 The listing
under the ESA of species threatened by global warming raises the possibility of
applying this law, which āadmits of no exception,ā9 and which affords endangered
species āthe highest of priorities,ā10 to the seemingly intractable issue of reducing
U.S. greenhouse gas emissions.
In this chapter we place the listings of the corals and polar bear in context. We
begin by providing an overview of the ESA, including its overarching objectives
and key provisions. We then discuss how the ESA should operate to protect species
imperiled by global warming and create an obligation on U.S. federal agencies
and corporations to reduce greenhouse gas emissions. We use the examples of
coral species and the polar bear to explore the possibilities and limitations of using
domestic wildlife law such as the ESA to bring the subject of global warming into
the courtroom and address otherwise unregulated greenhouse gas emissions.

GREENHOUSE GAS EMISSIONS
1.1. The Endangered Species Act: Overview
In the seminal ESA case, Tennessee Valley Authority v. Hill (TVA),11 the Supreme
Court held that the ESAā™s unequivocal mandate that federal agencies āinsureā that
their actions do not ājeopardizeā any species protected by the statute, meant that a
multimillion-dollar dam project already near completion could not proceed because
its completion threatened the existence of the snail darter, a small endemic ļ¬sh of
no known economic value.12 In so doing, the Supreme Court elevated a little-known
statute that had passed Congress with near unanimity into one of the most powerful
and controversial environmental statutes in the United States. In the three decades
since TVA was decided, courts enforcing the ESA have halted such activities as
logging, to protect threatened owls;13 commercial ļ¬shing, to protect Hawaiian monk
seals;14 military activities, to protect endangered whales;15 oil and gas development,

to protect grizzly bears;16 off-road vehicles, to protect imperiled plants;17 pesticide
authorizations, to protect imperiled salmon;18 and numerous other habitat-damaging
activities that threatened a particular protected species. In granting such injunctive
relief, courts have repeatedly found that ā[g]iven a substantial procedural violation
of the ESA in connection with a federal project, the remedy must be an injunction
of the project pending compliance with the ESA.ā19 Regardless of the economic
consequences of halting a given project, protection of the species must receive
The two primary mechanisms by which the ESA protects listed species are con-
tained in sections 7 and 9 of the statute. Section 7 directs all federal agencies
to āinsure through consultation with the Secretaryā21 that all actions authorized,
funded, or carried out by such agencies are ānot likely to jeopardize the continued
existenceā or āresult in the destruction or adverse modiļ¬cationā of ācritical habi-
tatā of any listed species.22 In contrast to the National Environmental Policy Act
(NEPA)23 ā“ which requires only informed agency decision-making and not a par-
ticular result,24 and is therefore strictly procedural ā“ section 7 of the ESA contains
both procedural (āthrough consultationā) and substantive (āinsureā the action does
not ājeopardizeā) mandates for federal agencies. As such, the statute, and litigation
under it, can force analysis through the consultation process of the environmental
effects of a given project and, if the project is determined to jeopardize a listed
species or adversely modify its critical habitat, trigger modiļ¬cation or cancellation
of the project so as to avoid such impacts.
While section 7 applies only to the actions of federal agencies, the prohibitions
of section 925 apply to āany person,ā including federal, state, and local agencies and

However, several marine mammals, including the polar bear, are managed by FWS.
16 U.S.C. Ā§ 1536(a)(2). To ājeopardizeā a species is deļ¬ned by regulation as āto engage in an action
that reasonably would be expected, directly or indirectly, to reduce appreciably the likelihood of both
the survival and recovery of a listed species in the wild by reducing the reproduction, numbers, or
distribution of that species.ā 50 C.F.R. Ā§ 402.02. A similar regulatory deļ¬nition of ādestroy or adversely
modify critical habitatā has been struck down by several courts as not properly encompassing recovery
of the species. See, e.g., Gifford Pinchot Task Force v. U.S. Fish and Wildlife Serv., 378 F.3d 1059,
1069ā“71 (9th Cir. 2004). While no replacement regulatory deļ¬nition has yet been promulgated, courts
have made clear that an agency action in critical habitat cannot compromise the speciesā™ recovery and
still rationally be deemed to have not āadversely modiļ¬edā that habitat. See, e.g., Ctr. for Biological

entities, individuals, and corporations.26 Section 9 prohibits, inter alia, the ātakingā
of any endangered species in the United States or upon the high seas.27 Regulations
promulgated pursuant to section 4(d) apply most of the take prohibitions applicable
to endangered species to threatened species as well.28 āTakeā means āto harass,
harm, pursue, hunt, shoot, wound, kill, trap, capture, or collect, or to attempt to
engage in any such conduct.ā29 āHarassā is further deļ¬ned as any āact or omission
which creates the likelihood of injury to wildlife by annoying it to such an extent
as to signiļ¬cantly disrupt normal behavior patterns which include, but are not
limited to, breeding, feeding or sheltering.ā30 āHarmā includes āsigniļ¬cant habitat
modiļ¬cation or degradation where it . . . injures wildlife by signiļ¬cantly impairing
essential behavioral patterns, including breeding, feeding or sheltering.ā31
The ESAā™s legislative history supports āthe broadest possibleā reading of ātake,ā32
and courts have consequently found violations of section 9 from activities ranging
from direct intentional killing of a listed species,33 to harm resulting from habitat
degradation,34 to government authorizations of activities that inevitably would result
in prohibited take, such as pesticide use35 or ļ¬shing.36 In perhaps the most expansive
reading of section 9ā™s reach to date, one appellate court found that āinadequate
regulationā of light pollution could make a local government liable for the take of
listed sea turtles.37
In addition to the prohibitions against jeopardy and take provided by sections
7 and 9, the ESA mandates an array of afļ¬rmative conservation actions for listed
species. These include the designation of ācritical habitat,ā38 the development and
implementation of recovery plans,39 the acquisition of land,40 and the release of

Section 1.4.3, infra, the lack of a blanket 4(d) rule applying Section 9 prohibitions to all Threatened

contains a ācitizen suitā provision allowing interested parties, such as nongovern-

1.2.1. Global Warming and Coral Reefs
Coral reefs are among the ļ¬rst ecosystems to show the signiļ¬cant adverse impacts
of global warming.50 An estimated 30 percent of coral reefs globally are already
severely degraded and 60 percent may be lost by 2030.51 The primary cause of
coral reef degradation on a global scale is bleaching, the expulsion of symbiotic
algal zooxanthellae from coral triggered, inter alia, by elevated sea temperatures.52

In 1998, which at the time was the warmest year on record, bleaching occurred
in every ocean, ultimately resulting in the death of 10 to 16 percent of the worldā™s
living coral.53 In 2005, which eclipsed 1998 as the warmest year on record,54 a major
bleaching event swept through the Caribbean, bleaching over 90 percent of live
coral in some areas and resulting in the ultimate death of about 20 percent of living
coral regionwide.55 Before this unprecedented single-year die-off even began, the
Caribbean contained the worldā™s most degraded coral reefs, having already lost as
much as 80 percent of live coral over the preceding thirty years.56 It will not take
many more episodes like the 2005 bleaching event before living coral reefs in the
Caribbean disappear entirely.57
While bleaching is perhaps the most widespread and worrisome impact of global
warming on coral reefs, it is far from being the only such impact. As the authors of
an authoritative review in 2003 put it:
The link between increased greenhouse gases, climate change, and regional-scale
bleaching of corals, considered dubious by many reef researchers only 10 to 20
years ago, is now incontrovertible. Moreover, future changes in ocean chemistry
due to higher atmospheric carbon dioxide may cause weakening of coral skeletons
and reduce the accretion of reefs, especially at higher latitudes. The frequency
and intensity of hurricanes (tropical cyclones, typhoons) may also increase in some
regions, leading to a shorter time for recovery between recurrences. The most
pressing impact of climate change, however, is episodes of coral bleaching and
disease that have already increased greatly in frequency and magnitude over the
past 30 years.58
The regional or global loss of coral reefs will have a devastating impact on global
biodiversity. Coral reefs are the oldest and most diverse ecological communities
on Earth59 ; they occupy less than 0.1 percent of the area of the worldā™s oceans, yet
harbor about a third of all described ocean species.60 Moreover, most coral reef
species remain undescribed, with estimates of an additional 1 million or more reef-
dependent species yet to be cataloged.61 The impending loss of coral reef ecosystems,
if allowed to proceed, will perhaps be the greatest anthropogenic extinction event

1.2.2. The Decline of Elkhorn and Staghorn Corals
Elkhorn coral (Acropora palmata) and staghorn coral (Acropora cervicornis) were, for
at least the past 3,000 years, the dominant reef-building corals in the Caribbean.62
Virtually every reef from the Florida Keys across the Caribbean to the Mesoameri-
can Reef in Belize was largely comprised of one or the other (or both) of these for-
merly ubiquitous species.63 However, over the past thirty years the two species have
declined by upwards of 90 percent.64 The primary drivers of the decline have been
disease and temperature-induced bleaching.65 Additionally, the period of decline
coincided with an ongoing period of increased hurricane activity, with intense storms
destroying entire reef tracts in certain areas.66 The cumulative result was that by the
beginning of the twenty-ļ¬rst century, elkhorn and staghorn corals had been reduced
to a scattering of mostly small colonies amid a large sea of coral rubble.67
The factors causing the decline of elkhorn and staghorn coral either are directly
correlated with global warming or represent examples of events likely to be more
prevalent and more intense in a warming climate.68 And while the link between coral
bleaching and global warming is relatively intuitive, even the outbreaks of coral dis-
ease that ravaged the two species have been linked to elevated water temperatures.69
Similarly, scientiļ¬c evidence indicates that global warming increases the probability
of severe weather events like the series of intense hurricanes that have so impacted
Caribbean reefs in recent decades.70 Finally, there is clear evidence that the record-
setting ocean temperatures of 1998 and 2005 that triggered widespread bleaching
and mortality are the product of global warming.71
In sum, over the course of less than three decades, elkhorn and staghorn corals
went from being the most visible and ecologically most important corals of Caribbean
reefs, a position they have held for at least 3,000 years, to species whose continued
existence beyond the next few decades is now in serious doubt. Global warming
helped bring them to this state and, absent signiļ¬cant reductions in greenhouse gas
emissions, is poised to be the ļ¬nal nail in their cofļ¬n.

tiers Ecology & Envā™t 307 (2004).
On top of these regionwide factors, the two corals virtually disappeared in the face of a diverse array
of threats, the primary ones being overļ¬shing and nutrient runoff, both of which promote algal
overgrowth, which smothers living coral. See Hughes, supra note 51, at 861.

1.2.3. From Petition to Listing
On March 4, 2004, a U.S. NGO, the Center for Biological Diversity, submitted a
petition to NMFS seeking listing of elkhorn and staghorn corals under the ESA.72
The 111-page petition detailed the decline of the species, projected future threats, and
argued that the corals were sufļ¬ciently imperiled to warrant the protections of the
ESA.73 Reļ¬‚ective of the scientiļ¬c literature documenting the speciesā™ decline, the
petition discussed the various factors negatively affecting the corals, with a particular
focus on the current and projected impacts of global warming.74
On June 23, 2004, NMFS made a positive ninety-day ļ¬nding, concluding that the
petition had presented āsubstantial information indicating the petitioned actions may
be warrantedā and announced the initiation of a formal status review as required
by section 4(b)(3)(A) of the ESA.75 On May 9, 2005, following a public comment
period and the completion of a status review, NMFS issued a proposed regulation to
list the two species as Threatened.76 A year later, on May 9, 2006, NMFS ļ¬nalized
the regulations, adding the two species to the ofļ¬cial list of Threatened species.77
While the ļ¬nal listing of the corals came three months after the statutory deadline,
the listing went through the regulatory process with remarkably little opposition or
more typical longer delays.78 Of the more than 1,300 comments submitted by sci-
entists and members of the public during the rulemaking process, not a single
comment opposed the listing.79 And while the listing process explicitly implicated
