efforts from public institutions, such as governments and companies. In the face of slow
climate change politics delaying climate change mitigation,
activists and lawyers have increased efforts to use national and international judiciary systems to advance the effort. Climate litigation typically engages in one of five types of legal claims:
Constitutional law
Constitutional law is a body of law which defines the role, powers, and structure of different entities within a state, namely, the executive, the parliament or legislature, and the judiciary; as well as the basic rights of citizens and, in ...

(claiming that failure to act on climate change is a failure to protect human rights).
Litigants pursuing such cases have had mixed results.
Since the early 2000s, the legal frameworks for combating climate change have increasingly been available through
legislation
Legislation is the process or result of enrolling, enacting, or promulgating laws by a legislature, parliament, or analogous governing body. Before an item of legislation becomes law it may be known as a bill, and may be broadly referred ...
, and an increasing body of court cases have developed an international body of law connecting climate action to legal challenges, related to constitutional law, administrative law, private law, consumer protection law or human rights.
Many of the successful cases and approaches have focused on advancing the needs of
climate justice and
the youth climate movement. Since 2015, there has been a trend in the use of human rights arguments in climate lawsuits,
in part due to the recognition of the
right to a healthy environment in more jurisdictions and at the United Nations.
High-profile climate litigation cases brought against states include ''
Leghari v. Pakistan'',
''
Juliana v. United States'' (both 2015), ''
Urgenda v. The Netherlands'' (2019), and ''
Neubauer v. Germany'' (2021), while ''
Milieudefensie v Royal Dutch Shell'' (2021) is the highest-profile case against a corporation to date. Environmental activists have asserted that investor-owned coal, oil, and gas corporations could be legally and morally liable for climate-related human rights violations, even though political decisions could prevent them from engaging in such violations. Litigations are often carried out via collective pooling of effort and resources such as via organizations like

, such as Greenpeace Poland which sued a coal utility and Greenpeace Germany which sued a car manufacturer. Such cases may take many years to unfold, and have occasionally been unsuccessful despite lengthy efforts, as was the case with ''Juliana v. United States''.
The 2010s saw a growing trend of activist cases successfully being won in global courts.
The 2017 UN Litigation Report identified 884 cases in 24 countries, including 654 cases in the United States and 230 cases in all other countries combined. As of July 1, 2020, the number of cases has almost doubled to at least 1,550 climate change cases filed in 38 countries (39 including the courts of the European Union), with approximately 1,200 cases filed in the US and over 350 filed in all other countries combined. By December 2022, the number had grown to 2,180, including 1,522 in the U.S.
The number of litigation cases is expected to continue rising in the 2020s.
There is a growing number of litigation cases, and international decisions can influence domestic courts. However, some cases work in the opposite direction: they challenge
climate action and are not aligned with
climate goals.
Methods and types of laws
Climate litigation typically falls into one of five broad areas of law:
*
Constitutional law
Constitutional law is a body of law which defines the role, powers, and structure of different entities within a state, namely, the executive, the parliament or legislature, and the judiciary; as well as the basic rights of citizens and, in ...
focused on breaches of constitutional rights by the state.
*
Administrative law
Administrative law is a division of law governing the activities of government agency, executive branch agencies of government. Administrative law includes executive branch rulemaking (executive branch rules are generally referred to as "regul ...
challenging the merits of administrative decision making within existing on-the-books laws, such as not granting permissions for high-emissions projects.
*
Private law
Private law is that part of a legal system that governs interactions between individual persons. It is distinguished from public law, which deals with relationships between both natural and artificial persons (i.e., organizations) and the st ...
challenging corporations or other organizations for negligence, nuisance, trespass, public trust, and unjust enrichment.
*
Fraud or consumer protection typically challenging companies for misrepresenting information about climate impacts.
*
Human rights
Human rights are universally recognized Morality, moral principles or Social norm, norms that establish standards of human behavior and are often protected by both Municipal law, national and international laws. These rights are considered ...
claiming that failure to act on climate change or to protect related natural resources, such as the atmosphere or the rainforest, fails to protect human rights.
These areas are not static. For instance,
Smith v Fonterra Co-operative Group Ltd argues for the new
tort
A tort is a civil wrong, other than breach of contract, that causes a claimant to suffer loss or harm, resulting in legal liability for the person who commits the tortious act. Tort law can be contrasted with criminal law, which deals with cri ...
of climate change damage and the
New Zealand Supreme Court duly ruled in 2024 that this novel civil wrong can be asserted in future proceedings.
Scale
The 2017 UN Litigation Report identified 884 cases in 24 countries, including 654 cases in the United States and 230 cases in all other countries combined. As of July 1, 2020, the number of cases has almost doubled to at least 1,550 climate change cases filed in 38 countries (39 including the courts of the European Union), with approximately 1,200 cases filed in the US and over 350 filed in all other countries combined. By December 2022, the number had grown to 2,180, including 1,522 in the U.S.
Scholars have observed a "rapidly growing landscape of climate litigation" (as of 2024) and say that courts are shaping law and governance trajectories, beyond the narrow confines of domestic law.
By type of action
Cases to increase accountability
Courts play a critical role in creating, increasing and imposing accountability on and for public authorities and private actors for climate and related harms caused by their actions or their failure to act. Courts articulate what it means for public and private actors to be accountable in relation to climate (in)action.
National courts have ordered governments to:
* legislate on climate change (e.g. ''Shrestha v Office of the Prime Minister'', 2018);
* define sufficiently ambitious mitigation targets (e.g. ''Klimaatzaak v Belgium'', 2021);
* develop a clear long-term emission-reduction strategy (e.g. ''Friends of the Irish Environment v Ireland'', 2020) or a realistic long-term emission reduction pathway (e.g. ''Neubauer v Germany'', 2021);
* present complete information on how it plans to achieve its statutory
carbon budget (e.g. ''Friends of the Earth v Secretary of State for Business, Energy and Industrial Strategy'', 2022);
* comply with a statutory carbon budget (e.g. ''Grande-Synthe v France'', 2021) or to take appropriate measures to achieve a statutory carbon budget (e.g. ''Oxfam v France'', 2021).

Ministry of Economy and Finance and
Cassa Depositi e Prestiti (both involved as co-owners),
requesting to set the beginning of the hearings in November of the same year.
Also known as ''La Giusta Causa'' ('The Right Cause'),
and based on the ''
Milieudefensie et al v Royal Dutch Shell'' court case,
it became the first climate lawsuit ever filed against a private-owned company in Italy.
The allegations focused on Eni's central role in increasing fossil fuel usage throughout the latest decades, despite being aware of the emissions' worst risks.
A ''
DeSmog'' inquiry revealed further evidence supporting the lawsuit's claims: firstly, a study commissioned by Eni itself from an affiliate research centre between 1969 and 1970, which had underlined the risk of a "catastrophic" climate crisis by 2000 posed by an unchecked rise in fossil fuel usage;
secondly, a 1978 report produced by Tecneco, another company owned by Eni, which had accurately estimated that the
CO2 concentration would have reached 375-400
ppm by 2000,
while noting that such changes to the thermal balance of the atmosphere could have had "serious consequences for the biosphere".
''DeSmog''

fossil fuels fall under the established torts of public nuisance and negligence and a new tort of climate change damage. Smith further argued that these seven corporations are harming his tribe's land, coastal waters, and traditional culture. Smith belongs to the Northland
tribes of
Ngāpuhi and
Ngāti Kahu. This judgment simply allows Smith to now pursue these matters in the
High Court. The defendants have indicated that they will seek to convince the court that climate change responses are better left to government policy and not subject to civil litigation.

United States
As of February 2020, the U.S. had the most pending cases with over 1,000 in the court system. Examples include
''Connecticut v. ExxonMobil Corp''. and ''
Massachusetts v. Environmental Protection Agency''. In the United States climate change litigation addresses existing principal laws to make their claim, most of them focusing on private and administrative law. The most popular principal laws to use are NEPA (the
National Environmental Policy Act), with 322 cases filed under its jurisdiction, the Clean Air Act, with 215 cases filed under its jurisdiction, the Endangered Species Act, with 163 cases filed under its jurisdiction. As more efforts continue on the front of climate change, as of August 2022, the federal government continues to approve agreements and class actions in terms of additional climate change initiatives. In addition, since 2015, there are about two dozen liability and fraud cases brought against some of the world's largest oil companies by various states for their role in denying climate policy leading to increased risks and costs borne to state governments. These states include New Jersey, District of Columbia, Delaware, Connecticut, Minnesota, Rhode Island, Massachusetts, and Vermont. Like Minnesota and the District of Columbia before it, New Jersey has also included the industry's top US trade group, the American Petroleum Institute in addition to ExxonMobil, Shell Oil, Chevron, BP and ConocoPhillips.
Actions using the Endangered Species Act
In the
Endangered Species Act

(ESA) case, ''
Tennessee Valley Authority v. Hill,'' the Supreme Court stated that the ESA mandates federal agencies to insure their actions do not jeopardize any species that are listed as endangered in the ESA.
Climate change litigation cases that use the ESA primarily focus on articles 7 and 9 of the statue. Article 7 states that all actions carried out by federal agencies must be unlikely to jeopardize the continued existence or result in the destruction of endangered species. Article 9 focuses not just on federal agencies but everybody, banning the taking of any endangered species by any party, be it federal, state, or private.
The first step for climate change activists is to make sure that species threatened by climate change are listed on the ESA by th

) to petition that the Arctic Polar Bear be listed on the ESA. The FWS under the Bush administration stretched the process out for years, missing many key deadlines and listing the species as "threatened" instead of endangered while the science was clearly in favor of an endangered listing. Facing mass public pressure and scientific consensus the FWS officially listed the species as endangered in May 2008.
Actions using the National Environmental Policy Act
The
National Environmental Policy Act (NEPA) recognizes that actions taken by the US government can have significant environmental impact and requires that all federal agencies consider these environmental implications when doing "major federal actions". This can be done either through an environmental assessment (EA) or a more thorough environmental impact statement (EIS), how thorough the analyzation has to be depends on the nature of the proposed action.
Actions using the Clear Air Act
The
Clean Air Act (CAA) regulates air pollutants both from stationary and mobile sources. The Act was passed in the 1970s before there was widespread knowledge about greenhouse gases (GHGs) but in 2007 the Supreme Court decided the EPA did have to regulate GHGs under the CAA due to the famous ''Massachusetts vs. The EPA'' case.
In 2009 the state of California was able to use the CAA to create stronger vehicle emission standards than the national standard, which quickly led to the Obama administration adopting these stricter emission standards on a national level. These standards were called th
Corporate Average Fuel Efficiency (CAFE)standards and included regulations of GHGs.

Dismissed cases
There are also cases that have been dismissed, whether due to lack of standing (e.g. ''Carvalho v Parliament and Council'', 2021) or due to the limits of judicial functions under the doctrine of the separation of powers (e.g. ''Juliana v United States'', 2020).

''Juliana v. United States''
In 2015, a number of American youth, represented by
Our Children's Trust, filed a lawsuit against the United States government, contending that their future lives would be harmed due to the government's inactivity towards
mitigating climate change. While similar suits had been filed and dismissed by the courts for numerous reasons, ''
Juliana v. United States'' gained traction when a District Judge
Ann Aiken ruled that the case had merit to continue, and that "a climate system capable of sustaining human life" was a fundamental right under the United States Constitution.
The lawsuit was eventually dismissed.

Problematic aspects
Scholars have pointed out that there are also potential negative impacts of successful cases – sometimes referred to as ''backlash litigation.'' As the number of successful cases increases the
energy transition risk to some companies operating in high-emitting sectors, it is possible that they will challenge government action on climate change. For example, they might argue that there was an alleged breach of international investment agreements even if governments' actions were taken to comply with a judicial decision.
One example is the case of ''
RWE v The Netherlands'', in which
RWE, a German energy company, filed suit against the Dutch government under the
Energy Charter Treaty, alleging that the government failed to allow adequate time and resources to enable the company to transition away from coal.
A study from 2024 found that: "Nearly 50 of the more than 230 recorded cases filed in 2023 include non‑aligned arguments. The vast majority of these were filed in the US. At times, actors involved in such cases appear to be intentionally seeking to use legal tactics to obstruct climate action".
