Our Children’s Trust with 15 Juliana Plaintiffs v. The United States of America

Summary:
On 23 September 2025, the NGO Our Children’s Trust announced that it had filed a petition before the Inter-American Commission on Human Rights alleging climate-related violations of human rights by the government of the United States of America on behalf of a group of youth. This petition follows the advisory opinion of the Inter-American Court of Human Rights on climate change, which was issued on 29 May 2025, as well as drawing on the climate advisory opinion of the International Court of Justice. The petitioners were formerly plaintiffs in the Juliana proceedings brought before US domestic courts on the basis of the public trust doctrine, among others.

Before the Inter-American Commission, the petitioners allege that the United States has known for decades that CO2 emissions cause climate change and that a transition away from fossil fuels is needed to protect human rights. They argue that, as the world’s largest emitter, the United States has played a leading role in causing climate change, and that its greenhouse gas emissions — and the resulting climate change — violate the human rights of children and youth, who are disproportionately impacted by its effects.

They claim before the Commission that the United States has failed to comply with its international obligations to guarantee the petitioners’ human rights, that it has a duty to prevent harm to the global climate system to guarantee those rights, that it brached its obligation to act with due diligence ot guarantee their rights and prevent harm to the climate system, that if violated its obligation to mitigate greenhouse gas emissions,a form of pollution, and that the United States’s deliberate emissions of greenhouse gasses violate the substantive rights of the petitioners as per the American Declaration, including the rights to life and health, the particular protections for children, equality and non-discrimination, the rights to home, property and private and family life, the right to culture, the right to dignity, and the right to a healthy climate.

They also invoke their procedural rights, namely the rights to access to justice and an effective remedy, alleging that the United States Department of Justice has deployed “extraordinary tactics” to silence the petitioners, and that the domestic courts failed to consider the merits of their claims.

In their request for relief, the petitioners inter alia request the Commission to:

  • order precautionary measures to prevent further irreparable harm;
  • join the admissibility and merits of the petition, in accordance with Article 37(4) of the Commission’s Rules of Procedure, given the serious and urgent nature of the case and the ongoing violations of Petitioners’ fundamental rights;
  • conduct an on-site country visit, including a visit with the Petitioners, and hold fact-finding hearings;
  • establish violations of Articles I (life), II (equality), V (private and family life), VI (family), VII (special protections for children), IX (inviolability of the home), XI (health), XIII (cultural life), XVIII (access to justice and effective remedies), XXIII (property), and XXIV (prompt and effective remedy) of the American Declaration and the rights to dignity (Preamble) and to a healthy climate; and
  • issue a country report with recommendations to the United States to remedy confirmed violations of international law, taking into account the clarifications of existing law set forth by the IACtHR and the ICJ in their in Advisory Opinions on the Climate Emergency and Human Rights and the Obligations of States in Respect of Climate Change.

Lighthiser v. Trump

Summary:  
On 29 May 2025, a case was filed on behalf of 22 youth plaintiffs from five US states (Montana, Oregon, Hawai‘i, California, and Florida) before the US District Court in the District of Montana with the support of the NGO Our Children’s Trust and others. The plaintiffs in this case contested a series of climate-related executive orders issued by the Trump administration, arguing that these measures threaten their constitutional rights to life, health, and safety. This includes executive orders aimed at “unleashing” fossil fuels, anti-clean energy measures and those removing climate science-related information from federal websites.

The case has been brought against US President Donald Trump as well as various government agencies and offices including the Environmental Protection Agency (EPA), the Department of the Interior (DOI), the Department of Energy (DOE), the Department of Transportation (DOT), the US Army Corps of Engineers (USACE), the National Aeronautics and Space Administration (NASA), the Department of Commerce (DOC), the National Oceanic and Atmospheric Administration (NOAA), the National Science Foundation (NSF), the Department of Health and Human Services (HHS), the National Institutes of Health (NIH), and the United States of America itself.  

Measures challenged:
The lawsuit challenges three specific executive orders, as well as measures to delete climate science information from government websites. The contested executive orders are the following:

  • Executive Order 14154: “Unleashing American Energy” (which prioritizes oil, gas, and coal over renewable energy).  
  • Executive Order 14156: “Declaring a National Energy Emergency” (which directs federal agencies to invoke emergency powers to fast-track fossil fuel production).
  • Executive Order 14261: “Reinvigorating America’s Beautiful Clean Coal Industry” (designating coal as a “mineral” under federal policy, thereby granting it priority status for extraction and development on public lands). 

Claims made:
The youth plaintiffs argue that the Trump administration’s executive orders violate their constitutional right to life (under the fifth amendment to the US Constitution) by increasing climate pollution. They also argue that the measures are an act of executive overreach, or in other words an ultra vires act going beyond presidential powers, and that augmenting fossil fuel production, suppressing climate science, and blocking clean energy solutions is a violation of the ‘state-created danger doctrine’, which triggers a governmental duty to protect against government-induced harm.

Sagoonick et al. v. State of Alaska II

Summary:
On 22 May 2024, a group of young people supported by the NGO ‘Our Children’s Trust’ filed suit against the U.S. State of Alaska arguing that statutory requirements to develop and advance the Alaska Liquefied Natural Gas (LNG) Project violate their public trust rights as well as their rights to substantive due process, life, liberty and property, and the right to protected natural resources for “current and future generations” under the Alaskan Constitution. They argue that this project will cause “existential harms to the lives, health, safety, and cultural traditions and identities of Alaska’s youth, and substantially limit their access to the vital natural resources upon which they depend.”

The case follows on an earlier case against Alaska, Sagoonick et al. v. Alaska I, which was rejected in 2022 by a divided Alaskan Supreme Court.

Claims made:
The case challenges legislation creating the Alaska Gasline Development Corporation, a state agency created to pursue building a new LNG pipeline. 

According to the plaintiffs, Alaska is “already in a state of climate disruption” and the contested project “would ensure continuing and substantially elevated levels of climate pollution for decades, locking in increasing and worsening harms to Youth Plaintiffs”. They argue that the youth plaintiffs are “uniquely vulnerable to climate change injuries and face disproportionate harms”. Arguing that climate pollution is already causing dangerous climate disruption in Alaska, injuring the plaintiffs in this case, they cite the following climate-related impacts:

  • temperature increase, heatwaves, and other heat-related changes;
  • thawing permafrost;
  • changing precipitation patterns, extreme weather events and droughts;
  • loss of sea, river, and lake ice;
  • ocean acidification;
  • melting glaciers and sea level rise; and
  • increasingly frequent and severe wildfires and smoke.

The plaintiffs sought a declaration that the contested provisions of State law violate their public trust rights to equal access to public trust resources and to sustained yield of public trust resources free from substantial impairment. They argued that the state of Alaska has a duty under the public trust doctrine to ensure “the continuing availability of public trust resources for present and future generations”.

In addition, they sought a declaration that they have a fundamental right to a climate system that sustains human life, liberty, and dignity under the Alaskan Constitution, which is being violated by the contested statutory provisions.

The youth plaintiffs also petitioned the court to enjoin the defendants from taking further actions to advance or develop the Alaska LNG Project. They sought costs and expenses as well as “such other and further relief as the Court deems just and equitable.”

Recent developments:
In October 2024, it was reported that the state of Alaska had asked the Court to dismiss the case.

Sagoonick et al. v. State of Alaska I

Summary:
In 2017, sixteen children and young people — including some who were members of Alaskan Indigenous peoples — filed suit against the U.S. State of Alaska arguing by the state’s climate and energy policy violated their constitutional rights. Because the policy in question authorized and facilitated activities producing greenhouse gas emissions, the plaintiffs alleged violations of their due process rights to life, liberty, and property under the Alaskan Constitution, as well as their right to a stable climate system. The argued that the state government and relevant agencies had, “knowingly and with deliberate indifference”, created a dangerous situation for them, in violation of their constitutional rights. The plaintiffs also made an equal protection claim and alleged a violation of Alaska’s public trust doctrine.

The plaintiffs sought declaratory relief. They sought a declaration that the state had a constitutional duty to protect their constitutional rights, as well as a duty under the public trust doctrine to protect Alaska’s waters, atmosphere, land, fish, wildlife, and other public trust resources. They sought a declaration that the state’s climate and energy policy had violated their rights and placed them “in a position of danger with deliberate indifference to their safety” and had “materially caused, contributed to, and/or exacerbated climate change and discriminated against Youth Plaintiffs as members of a protected class, and with respect to their fundamental rights”. They sought an order for the state to prepare a complete and accurate accounting of Alaska’s GHG emissions and an enforceable state climate recovery plan.

Alaska Superior Court Judgment:
On 30 October 2018, the Alaska Superior Court rejected the case, arguing that it was indistinguishable from previous climate cases based on the public trust doctrine and that it concerned political questions which were not justiciable. The plaintiffs appealed.

Alaska Supreme Court Judgment:
In 2022, on appeal, the Alaska Supreme Court affirmed the dismissal of the case (see full text of the judgment below). The Court found that the applicants’ claims concerned non-justiciable political questions and found that it could not make “the legislative policy judgments necessary to grant the requested injunctive relief.”

Judge Maassen, dissenting, argued that he was “no longer convinced that nothing can be gained by clarifying Alaskans’ constitutional rights and the State’s corresponding duties in the context of climate change”, and that the public trust doctrine under the Alaskan Constitution provided a right to a livable climate.

Additional developments:
A follow-up case, Sagoonick et al. v. State of Alaska II, was filed in 2022.

Genesis B. v United States Environmental Protection Agency (EPA)

Summary:
On 10 December 2023, 18 children from California, aged 8 to 17, initiated a constitutional climate lawsuit titled Genesis B. v. United States Environmental Protection Agency (EPA). The lawsuit targets not only the EPA but also its administrator, Michael Regan, and the U.S. federal government. The central claim put forth by the young plaintiffs is that the EPA, responsible for regulating greenhouse gas emissions, is deliberately allowing life-threatening climate pollution to be emitted by fossil fuel sources under its jurisdiction. According to the plaintiffs, this negligence is causing substantial harm to the health and welfare of children. Furthermore, the children argue that the EPA is engaging in discrimination against them as a distinct group of individuals by discounting the economic value of their lives and their future when making decisions about the permissible levels of climate pollution. The plaintiffs assert that such actions violate their constitutional rights, specifically the right to equal protection of the law and the right to life.

This legal action represents the most recent development in a sequence of constitutional climate cases initiated by the nonprofit legal organisation Our Children’s Trust and led by youth activists. Notably, Our Children’s Trust achieved a significant milestone in August 2023 with the Held and Others v. Montana case. In this instance, a judge sided with plaintiffs who contended that the state’s policies favouring fossil fuels encroached upon their constitutional entitlement to a clean and healthful environment

Claim:
The youth involved in Genesis B. v. United States Environmental Protection Agency assert that the EPA’s actions violate their fundamental constitutional rights, specifically the right to equal protection of the law and the right to life and liberty. They seek a declaratory judgment from the federal court and are urging the court to establish a unique standard of judicial review that recognises and protects the equal protection rights of children. Ultimately, the plaintiffs aim to compel the EPA to cease permitting life-threatening levels of fossil fuel climate pollution and, in alignment with scientific recommendations, phase out fossil fuel pollution by 2050.

Held and Others v. Montana

Summary:
In Held and Others, sixteen young plaintiffs aged between two and eighteen brought a case against the U.S. state of Montana alleging violations of the state constitution due to climate change. The youth plaintiffs in this case, which is to some extent comparable to the Juliana litigation, alleged that they are already experiencing ‘a host of adverse consequences’ from anthropogenic climate change in Montana, including increased temperatures, changing weather patterns, more acute droughts and extreme weather events, increasing wildfires and glacial melt. Fossil fuels extracted in Montana cause emissions higher than those of many countries, including Brazil, Japan, Mexico, Spain, or the United Kingdom. The plaintiffs argued that this was causing health risks, especially for children, and that the defendants, among them the state of Montana, its Governor, and various state agencies, had “act[ed] affirmatively to exacerbate the climate crisis” despite their awareness of the risks to the applicants. On 14 August 2023, Judge Kathy Seeley ruled wholly in favor of the youth plaintiffs, declaring that Montana had violated their constitutional rights and invalidating the statutory rule forbidding state authorities from considering the impacts of GHG emissions or climate change in decision-making related to fossil fuel extraction. In 2025, 13 of the 16 original plaintiffs filed non-compliance proceedings based on new state legislation.

Claims made:
The plaintiffs challenged the constitutionality of fossil fuel-based provisions of Montana’s State Energy Policy Act along with a provision of the Montana Environmental Policy Act which forbids state authorities from considering the impacts of GHG emissions or climate change in their environmental reviews (the “MEPA Limitation”). They also challenged the aggregate acts that the state has taken to implement and perpetuate a fossil fuel-based energy system under these statutes.

The plaintiffs sought a declaration that their right to a clean and healthy environment includes a right a stable climate, and that existing approaches to greenhouse gas emissions in Montana violate constitutional provisions, including the right to a clean and healthy environment; the right to seek safety, health, and happiness; and the right to individual dignity and to equal protection. They also sought injunctive relief, namely an order to account for Montana’s greenhouse gas emissions and to develop and implement an emissions reductions plan.

Decision on the admissibility:
On 4 August 2021, a the Montana First Judicial District Court for Lewis and Clark County declared the case admissible in part. The prayer for injunctive relief in terms of emissions accounting, a remedial plan or policy, the appointment of expert to assist the court, and retain jurisdiction until such orders are complied with were rejected. However, the court declared the constitutional rights claims admissible, including the claim about the plaintiffs’ ‘fundamental constitutional right to a clean and healthful environment’, which — as the plaintiffs submitted — ‘includes a stable climate system that sustains human lives and liberties’.

Judge Seeley’s Ruling of 14 August 2023:
After a trial held from 12-23 June 2023, Judge Kathy Seeley of the First Judicial District Court of Montana issued a ruling in this case on 14 August 2023. Noting that “[t]he science is clear that there are catastrophic harms to the natural environment of Montana and Plaintiffs and future generations of the State due to anthropogenic climate change”, she ruled wholly in favor of the plaintiffs, declaring that the state of Montana had violated their constitutional rights to equal protection, dignity, liberty, health and safety, and public trust, all of which are predicated on their right to a clean and healthful environment (p. 92-93).

In doing so, Judge Seeley ruled that the youth plaintiffs had standing to bring the case because they had proven that they had experienced significant injuries. The court set out the different impacts on the plaintiffs at length (p. 46-64). It ultimately found that the plaintiffs “have experienced past and ongoing injuries resulting from the State’s failure to consider GHGs and climate change, including injuries to their physical and mental health, homes and property, recreational, spiritual, and aesthetic interests, tribal and cultural traditions, economic security, and happiness” (p. 86 of the ruling). The judge also ruled that while mental health injuries based on state inaction on climate change do not on their own constitute a cognizable injury, “mental health injuries stemming from the effects of climate change on Montana’s environment, feelings like loss, despair, and anxiety, are cognizable injuries” (p. 86-87). The ruling recognizes that “[e]very additional ton of GHG emissions exacerbates Plaintiffs’ injuries and risks locking in irreversible climate injuries”, and that these injuries “will grow increasingly severe and irreversible without science-based actions to address climate change” (p. 87). As children and youth, the plaintiffs are disproportionately impacted by fossil fuel pollution and climate impacts, and their injuries are “concrete, particularized, and distinguishable from the public generally” (p. 87).

On causation, and having heard and evaluated testimony from several expert witnesses, the Court extensively reviewed the scientific evidence concerning the causation and progression of anthropogenic climate change and identified the Earth’s energy imbalance as the critical metric for determining levels of global warming (p. 22). Having established that “Montana is a major emitter of GHG emissions in the world in absolute terms, in per person terms, and historically”, and noting the state government’s continuing approval of fossil fuel projects despite its already extensive production of oil, gas and coal, the Court found that there was a “fairly traceable connection” between Montana’s statutes, its GHG emissions, climate change, and the injuries suffered by the plaintiffs (p. 87). Noting that the state government had the authority to limit fossil fuel-related activities, and having regard to the fact that the MEPA Limitation causes the state to ignore climate impacts and renewable energy alternatives to fossil fuels, as well as noting the economic and environmental advantages of a green energy transition for Montana, the Court noted that “current barriers to implementing renewable energy systems are not technical or economic, but social and political” (p. 83). The state of Montana, it held, “authorizes fossil fuel activities without analyzing GHGs or climate impacts, which result in GHG emissions in Montana and abroad that have caused and continue to exacerbate anthropogenic climate change” (p. 88). It noted also that these emissions were “nationally and globally significant”, and could accordingly not be considered de minimis; they “can be measured incrementally and cumulatively both in terms of immediate local effects and by mixing in the atmosphere and contributing to global climate change and an already destabilized climate system” (p. 88).

On the redressability of these impacts, the Court noted that the psychological satisfaction of the ruling itself did not constitute sufficient redress, and that declaring the relevant state statutory rules unconstitutional would provide partial redress because ongoing emissions will continue to cause harms to the plaintiffs. Noting that “[i]t is possible to affect future degradation to Montana’s environment and natural resources and injuries to these Plaintiffs”, and applying strict structiny to the state’s statutes, the Court found that the MEPA Limitation violates the right to a clean and healthful environment under the Montana Constitution, which protects children and future generations (among others) and includes the protection of the climate system. As a result, the Court tested whether the MEPA Limitation was narrowly tailored to serve a compelling government interest, finding that neither had the state authorities shown that it served a compelling governmental interest, nor was it narrowly tailored to serve any interest.

As a result, the judge invalidated the Montana legislation that promoted fossil fuels and prohibited analysis of GHG emissions and corresponding climate impacts.

Proceedings on non-compliance:
On 10 December 2025, a petition on behalf of 13 of the original 16 plaintiffs in the case filed a petition for original jurisdiction with the Montana Supreme Court. They challenged statutes passed by the Montana legislature in 2025, arguing that they weaken the state’s environmental protection laws and undermine the state’s constitutional obligation to protect the environment. The petition seeks a declaration that these statutes are unconstitutional, and to overturn them.

Navahine F., a Minor v. Dept. of Transportation of Hawai’i et al.

Summary:
In January 2022, fourteen young people filed suit against the Department of Transportation of the US state of Hawai’i (HDOT), its Director, the state’s Governor, and the State itself. In Hawai’i Circuit Court, they alleged that the state’s transportation system violated the Hawai‘ian Constitution’s public trust doctrine and the right to a clean and healthful environment that it enshrines. The plaintiffs argued that the state and its authorities had “engaged in an ongoing pattern and practice of promoting, funding, and implementing transportation projects that lock in and escalate the use of fossil fuels, rather than projects that mitigate and reduce emissions”. Arguing that Hawai’i was the most carbon-dependent state in the nation, they sought declaratory and injunctive relief. They made a variety of arguments about the destruction of the Hawai’ian environment, coral reefs, native species of plants and marine life, and beaches; about their health and well-being, including about climate anxiety and about existing health conditions that are aggravated by the effects of climate change; about flooding and its impact on their ability to go to school; about water and food security, including impacts on traditional food sources, traditional and indigenous ways of life and culture; about wildfires; and about climate anxiety.

Claims made:
The plaintiffs note that Article XI, section 1 of the Hawai’i Constitution requires Defendants “[f]or the benefit of present and future generations,” to “conserve and protect Hawai’i’s natural beauty and all natural resources.” Article XI, section 1 further declares that “[a]ll public natural resources are held in trust by the State for the benefit of the people.” The Constitution also explicitly recognizes the right to a clean and healthful environment. Noting the special vulnerability of Hawai’i to climate-related ecological damage, including from sea-level rise, and the disproportionate harm to children and youth, including the lifetime exposure disparities concerning extreme events such as heat waves, wildfires, crop failures, droughts, and floods, they allege that the state of Hawai’i, through its Department of Transportation, has “systematically failed to exercise its statutory and constitutional authority and duty to implement Hawai’i’s climate change mitigation goals and to plan for and ensure construction and operation of a multimodal, electrified transportation system that reduces vehicle miles traveled and greenhouse gas emissions, and helps to eliminate Hawai’i’s dependence on imported fossil fuels”.

Ruling on Motion to Dismiss:
On 6 April 2023, the First Circuit Court rejected the respondent’s motion to dismiss the case for failure to state a claim. The state had argued that the public trust doctrine did not apply to the climate, “because climate is not air, water, land, minerals, energy resource or some other “localized” natural resource.” It had also argued that any efforts by the state would not have an impact on climate change given the scale of the problem.

The Court held in this regard that, in any event, the state as trustee had an obligation to keep its assets, i.e. its trust property, from falling into disrepair. It thereby rejected the argument that climate change was “too big a problem” and the idea that the state had no obligation to reasonably monitor and maintain its natural resources by reducing greenhouse gas emissions and planning alternatives to fossil-fuel heavy means of transportation. The Court also recognized that “the alleged harms are not hypothetical or only in the future. They are current, ongoing, and getting worse.”

On the argument that the applicants did not have a sufficient interest in the case, the Court held that the plaintiffs “stand to inherit a world with severe climate change and the resulting damage to our natural resources. This includes rising temperatures, sea level rise, coastal erosion, flooding, ocean warming and acidification with severe impacts on marine life, and more frequent and extreme droughts and storms. Destruction of the environment is a concrete interests (sic).”

Finding that arguments based on the political question doctrine were premature in this case, and citing case-law finding that this doctrine does not bar claim based on public trust duties, the Court denied the motion to dismiss the case.

Trial date set:
It was announced in August 2023 that trial dates for this case had been scheduled for 24 June-12 July 2024 at the Environmental Court of the First Circuit for Hawai’i. This would make this only the second-ever constitutional rights climate case to go to trial in the United States, after the Held and others v. Montana case. The case will be heard by First Circuit Judge John Tonaki.

Settlement Agreement:
On 20 June 2024, Hawai’i officials announced a groundbreaking Settlement Agreement with plaintiffs, marking a significant milestone. The Court approved the historic Navahine Agreement as fair and in the best interests of the youth plaintiffs. This landmark Agreement upholds children’s constitutional rights to a climate capable of sustaining life and mandates transformative changes in Hawai’i’s transportation system.

The Agreement emphasises HDOT’s responsibility to preserve Hawai’i’s public trust resources and ensure a clean and healthy environment for all residents. By 2045, HDOT is committed to achieving zero emissions across all modes of transportation, including ground, sea, and interisland air travel. The Agreement also includes numerous provisions for immediate and ongoing action by HDOT, such as establishing a Greenhouse Gas Reduction Plan, creating designated units and roles within HDOT, forming a youth council, improving transportation infrastructure budgeting processes, and making immediate, ambitious investments in clean transportation infrastructure. The Court will retain jurisdiction over the agreement until 2045 to oversee compliance with its terms.

This Settlement Agreement sets a precedent as the first of its kind, where government defendants collaborate with youth plaintiffs to address constitutional climate concerns. It commits to the systemic decarbonization of Hawai’i’s transportation sector, aiming to significantly reduce greenhouse gas emissions and lessen dependence on fossil fuels.

Reynolds and Others v. Florida

Summary:
In this case, eight young people asserted that the “deliberate indifference” of the US state of Florida, its Governor Ron DeSantis, and other state agencies had violated their “fundamental rights of life, liberty and property, and the pursuit of happiness, which includes a stable climate system”. On 9 June 2020, the Circuit Court for Leon County dismissed their case, finding that it could not grant the relief requested in light of the separation of powers clause contained in the state’s constitution. The claims in question were considered nonjusticiable because they “are inherently political questions that must be resolved by the political branches of government.”. On appeal, on 18 May 2021, the First District Court of Appeal rejected the applicants’ appeal, affirming the lower court’s finding that the lawsuit raised nonjusticiable political questions.

Aji P. and Others v. the State of Washington

Summary:
This case was brought by 13 young people aged between 8 and 18 who sued the US State of Washington, its Governor, and various other state agencies, arguing that the state had “injured and continue[d] to injure them by creating, operating, and maintaining a fossil fuel-based energy and transportation system that [the State] knew would result in greenhouse gas (“GHG”) emissions, dangerous climate change, and resulting widespread harm.” In doing so, they invoked their “fundamental and inalienable constitutional rights to life, liberty, property, equal protection, and a healthful and pleasant environment, which includes a stable climate system that sustains human life and liberty.” They also invoked the impacts on indigenous peoples’ rights. The plaintiffs requested the judiciary to “[o]rder [the state] to develop and submit to the Court . . . an enforceable state climate recovery plan”.

A number of amici filed briefs in the case. For example, the Swinomish Indian Tribal Community, Quinault Indian Nation, and Suquamish Tribe argued that local tribes were already seeing impacts on their traditional lands and abutting marine waters. The Environmental Law Alliance Worldwide (ELAW-US) noted the well-documented impacts of climate change on human and constitutional rights. The League of Women Voters of Washington argued that access to judicial action was particularly important for minors who did not enjoy access to the right to vote. And a group of environmental NGOs submitted that “the right to a healthful and pleasant environment underlies our continued ability to claim our explicitly-guaranteed rights to life and liberty.”

On 8 February 2021, the Court of Appeals of the State of Washington held that it “firmly believe[d] that the right to a stable environment should be fundamental.” It also recognized “the extreme harm that greenhouse gas emissions inflict on the environment and its future stability.” However, it held that “it would be a violation of the separation of powers doctrine for the court to resolve the Youths’ claims.” It accordingly dismissed the claim.

On 6 October 2021, the Supreme Court of the State of Washington denied the petition for review in this case. González, C.J. (dissenting) noted that the plaintiffs “asked this court to recognize a fundamental right to a healthful and pleasant environment that may be inconsistent with our State’s maintenance of a fossil-fuel-based energy and transportation system that it knows will result in greenhouse gas emissions. These greenhouse gases hasten a rise in the earth’s temperature. This temperature change foreshadows the potential collapse of our environment. In its place is an unstable climate system, conceivably unable to sustain human life and continued enjoyment of ordered liberty under law. Today, we have an opportunity to consider whether these are the sorts of harms that are remediable under Washington’s law and constitution. We should have granted review to decide that question”.

On 12 August 2015, the Juliana v. the United States case was filed in the U.S. District Court for the District of Oregon. The 21 youth plaintiffs in this case, who were represented by the NGO “Our Children’s Trust”, asserted that the government had violated the youngest generation’s constitutional rights to life, liberty and property through its climate change-causing actions. Among other things, they argued that they had suffered psychological harms, damage to property, impairment to their recreational interests, and that their medical conditions had been exacerbated by the effects of climate change. They sought declaratory relief and an injunction ordering the government to implement a plan to phase out fossil fuels. Moreover, they stated that the government had failed to protect essential public trust resources by encouraging and permitting the combustion of fossil fuels. After extensive proceedings, the Ninth Circuit Court of Appeals ordered the dismissal of the case in 2024, and the US Supreme Court refused to grant certoriari in March 2025, effectively ending the case.

The Ninth Circuit’s 2020 decision:
The Government filed a large number of motions to stay or deny these procedings. However, U.S. District Court of Oregon Judge Ann Aiken declined to dismiss the lawsuit. She ruled that access to a clean environment constitutes a fundamental right. Judge Aiken’s judgment was reversed by a Ninth Circuit Panel on 17 January 2020 due to the plaintiffs’ lack of standing to sue. The Ninth Circuit Court of Appeals recognized the gravity of the evidence on the plaintiffs’s injuries from climate change. The panel of judges also recognized the existence of harms to the applicants, and the plausibility of arguing that these harms had been caused by climate change. Nevertheless, the Court held that the plaintiffs’ requested remedies should be addressed by the executive and legislative branches and not by the courts. As a result, they “[r]eluctantly” held that “such relief is beyond [their] constitutional power.”

One of the three judges affirmed the plaintiff’s constitutional climate rights in a dissent, arguing that the case sought to enforce the US Constitution’s most basic principle: “that the Constitution does not condone the Nation’s willful destruction.” Accordingly, she held that the plaintiffs had standing to challenge the government’s conduct, and had presented sufficient evidence to press their constitutional rights claims at trial.

Further proceedings:
On 9 March 2021, the plaintiffs filed a motion to amend their complaint and adjust the remedy sought in the case. After settlement talks ended without resolution in November 2021, and Judge Aiken granted the plaintiff’s motion for leave to file a second amended complaint in June 2023. The plaintiffs argued that the government’s failure to address climate change violated their rights under the Fifth and Ninth Amendments and the Public Trust Doctrine. The amended complaint requested the court to issue an injunction restraining the defendants from carrying out policies, practices that render the national energy system unconstitutional in a manner that harms the plaintiffs.

In December 2023, the court partially denied the defendants’ motion to dismiss the second amended complaint, allowing claims related to the right to a climate system capable of sustaining life under the Due Process Clause and the Public Trust Doctrine to proceed. However, in February 2024, the government filed an emergency petition for a writ of mandamus, which was granted by a three-judge panel of the Ninth Circuit Court of Appeals in May 2024. This order required the district court to dismiss the case and preclude any further amendments. Subsequently, the district court dismissed the case.

These were complex proceedings, with several intermediate filings and actions. However, on 24 March 2025, the US Supreme Court denied the plaintiffs’ petition for a writ of certoriari. The plaintiffs had sought review of the order of the Ninth Circuit of May 2024, which granted the government’s request for a writ of mandamus and ordered the district court to dismiss the case. At the time of writing, this seems to have effectively ended the case.
