PSB et. al. v. Brazil (Amazon deforestation)

Summary:

On 11 November 2020, seven political parties with representation in Brazil’s National Congress brought an action against the Brazilian government before the Federal Supreme Court of Brazil. The petition sought the effective implementation of the public policy to combat deforestation in Brazilian Amazon, viz. the Action Plan for Prevention and Control of the Legal Amazon Deforestation (PPCDAm). The petition is in the nature of an Allegation of Disobedience of Fundamental Precept (ADPF). The ADPF claimed that the government’s actions and omissions in relation to the protection of forests in the Amazon, including within Indigenous Lands and Federal Conservation Units violates constitutional rights and prevents Brazil from fulfilling its climate targets assumed under the Paris Agreement and transposed into national laws.  

The Federal Supreme Court decided in favour of the petitioners and ordered the Federal government to resume the PPCDAm, and strengthen the governmental organs linked to the socio-environmental agenda. The effect of this order was stopped on account of another judge of the Federal Supreme Court seeking a review of the decision.  

Facts of the case:

The petitioners earmarked 2019-2020 as the relevant period for the purposes of the ADPF, since this period is allegedly marked by unprecedented attacks on Article 225 of the Brazilian Constitution which guarantees the right to an ecologically balanced environment. The petitioners alleged that the government abandoned and stopped enforcing the PPCDAm. They further alleged that the government has explicitly refused to cooperate with monitoring agencies and authorities for inspection and control of the use of forests (including the Brazilian Environmental Protection Agency); frozen the financing for the public policy for combating deforestation; and increased environmental deregulation. By way of evidence, the petitioners relied on statistics demonstrating an increase in deforestation notwithstanding a drastic reduction in notices of violations and cease-and-desist orders relating to forest conservation laws. They also relied on budget data of the main agencies which are entrusted with the execution of the public policy on combatting deforestation, and evidence pointing to the non-cooperation of the military in enforcement action.  

Claims:

The petition alleged violations of constitutional rights, viz. the right of present and future generations to an ecologically balanced environment (Article 225), which they argue includes a derivative ‘fundamental the integrity of the climate system or a fundamental right to a stable and secure climate’; rights of indigenous peoples to their traditional lands (Article 231); and cultural rights (Articles 215 and 216). The petitioners also argued that the government’s lack of transparency about implementation of the PPCDAm, its campaign to discredit agencies and institutions which provide data and information on the environment, including Federal agencies, and its denial of deforestation and climate change constitute violations of the right to information.  

The Attorney General argued against the admissibility of the action on multiple grounds, viz. (i) that the action does not concern a constitutional issue and is rather a matter of administrative law, since the reliefs (administrative measures) requested by the petitioners do not directly follow from the text of the Brazilian Constitution; (ii) that admitting the case would run counter to the subsidiarity principle enshrined in the procedural law of the Federal Supreme Court, which requires that it should avoid admitting actions in the nature of an ADPF when there are other effective means of remedying the damage; and (iii) that the procedure for control of constitutionality is not suitable for allowing broad examination of evidence. The Attorney General further refuted the statistical evidence raised by the petitioners arguing that the reduction in number of notices of violations and cease-and-desist orders was attributable to the COVID-19 pandemic. On the merits, the Attorney General contended that the Federal Government had the prerogative to modulate its administrative strategies in line with the legal framework.  

Decision:

On 6 April 2022, Minister Cármen Lúcia of the Federal Supreme Court issued a decision in favour of the petitioners. She rejected the contentions of the Attorney General, deciding that there is no doubt as to the constitutional nature of the issues raised in the action; that a review of the Federal government’s actions in relation to the problem of deforestation in the Brazilian Amazon, which has negative repercussions for the climate, falls within the Federal Supreme Court’s jurisdiction; and the examination of evidence is not practically difficult (owing to the sufficiency of the information provided by governmental agencies and amici curae). The decision notes that non-compliance by Brazilian state organs with commitments under international environmental treaties amounts to a violation of the environmental duties emanating from the Constitution. Reading the principle of non-retrogression into Article 225 of the Constitution, the decision identifies acts of the Federal Government which were contrary to such principle.  

Relief:

The Court declared that the situation regarding the illegal deforestation of the Amazon rainforest and the omissions of the Brazilian State in relation to its protective functions was unconstitutional. It ordered the Federal Government to present a detailed plan for the implementation of the PPCDAs and effective protection measures relating to the Amazon forest and the rights of indigenous peoples and other inhabitants in protected areas, within 30 days from the decision. The decision also lists concrete benchmarks and targets that the Federal Government’s plan ought to be based on and seek to achieve.  

Status:

Immediately following Minister Cármen Lúcia’s decision, Minister André Mendonça of the Federal Supreme Court requested a review of that decision, which effectively blocked the decision. As a result, the effect of the decision requiring the Federal Government to take certain actions within a set date stands suspended. The case is still pending before the Federal Supreme Court.

Citizens’ Committee on the Kobe Coal-Fired Power Plant v. Kobe Steel Ltd., et al.

Summary:
On 20 March 2023, a first-instance court in Japan heard a civil case concerning the construction and operation of new coal-fired power plants brought by the citizens of Kobe. Two weeks previously, on 9 March 2023, the Japanese Supreme Court refused to hear its first-ever administrative climate case concerning the same set of facts, giving no substantive reasons for doing so. In the civil case, which was filed in 2018, 40 citizens of Kobe brought suit against three corporations involved in the construction and operation of the plants. They argued that these plants would impact themtheir personal rights and right to a peaceful life both through air pollution and through their contribution to the climate change.

As Grace Nishikawa and Masako Ichihara have explained on the Sabin Center’s Climate Law Blog, ‘personal rights’ are established through case-law and frequently enter into play in environmental cases. They protect personal well-being, including the rights to life, bodily integrity, health, and a peaceful life (the last of which the authors compare to the right to respect for private and family life under Article 8 of the European Convention of Human Rights). The plaintiffs in this case invoked these personal rights, arguing that the coal plants would aggravate climate change, leading to extreme heat and rainfall events that would directly affect them. In their submissions, they made arguments based on international and comparative law, mentioning carbon budgets, the Paris Agreement, the Dutch Urgenda case, and the Glasgow Climate Pact.

In its first-instance judgment, the Kobe District Court accepted that greenhouse emissions, including those from the plant, contribute to climate change and can violate personal rights. However, it found the risk of harm to the individual plaintiffs to be too uncertain, and rejected their claim, noting the difficulty of causally attributing responsibility for damage related to climate change.

Concerning the alleged violation of the right to a peaceful life, which the plaintiffs argued contains a right to a healthy and peaceful life, the Court likewise rejected this claim, for the same reasons, finding that fears about climate change were not concrete enough to constitute human rights violation. The Court also noted that there was no legally recognized right stable climate in Japan.

Concerning the additional air pollution complaint, the Court found that this was not serious enough to constitute a concrete danger to the plaintiffs’ rights. It also did not engage with the plaintiffs’ request for a preliminary injunction halting the operation of the coal plants.

Appeal:
Climate Case Chart reports that an appeal in this case was filed on 4 January 2023.

Climate Crisis Emergency Action v. South Korea (Byung-In Kim et al. v. South Korea)

Summary:
In October 2021, the South Korean NGO “Climate Crisis Emergency Action” filed a constitutional complaint on behalf of 130 parties concerning the country’s greenhouse gas emissions reductions targets as set out in the South Korean Basic Act on Carbon Neutrality and Green Growth (the Carbon Growth Act), which was promulgated on 24 September 2021. On 29 August 2024, the Constitutional Court of South Korea issued its judgment in this and three other mitigation cases.

In a draft of the application form available online (in Korean), the applicant organization noted the Korean National Assembly’s statement in support of the 1.5 degree emissions reductions target under the Paris Agreement, and the insufficiency of the domestic mitigation action to meet that target. It submitted that the domestic target is “an arbitrary and irresponsible reduction target set in defiance of the standards agreed upon by the scientific community and the international community.” Noting the State’s “duty to protect the basic rights of its citizens” (in Article 10 of the South Korean Constitution), it submitted that fundamental rights are already being violated and will continue to be violated, and that higher legislative ambition is required.

Claims made (as per the version of the application made available here):
The plaintiffs in this case contested Article 8(1) of the Carbon Growth Act, which stipulates that “the government shall reduce national greenhouse gas emissions by a rate prescribed by Presidential Decree by at least 35 percent of the national greenhouse gas emissions in 2018 by 2030 as the mid- to long-term national greenhouse gas reduction target.” The plaintiffs argued that this goal was arbitrary and irresponsible and that ot ignored climate scientific findings and the standards agreed upon by the international community, and that it is not based on a ‘carbon budget (total greenhouse gas emissions)’ necessary to prevent the climate crisis. Furthermore, they argued that the Carbon Growth Act is based on ‘groundless optimism’ about technology and market-based ‘green growth’ and that it favors corporate interests over constitutional rights protection.

In concreto, the plaintiffs invoked the right to pursue human dignity, value and happiness in Article 10 of the South Korean Constitution, along with the right to live a life worthy of humanity in Article 34, and the right to live in a healthy and pleasant environment in Article 35. They also invoked Article 36 of the Constitution concerning the protection of public health and disaster prevention. Citing scientific evidence concerning increasing natural disasters, food and water shortages, security crises and social disasters, they submitted that “the obligation to protect fundamental rights from climate change has been fulfilled only when measures corresponding to the minimum level agreed upon in the international community are taken.”

The applicants explicitly linked their case to the German Neubauer judgment concerning the impact of unambitious climate policy on the rights of future generations, as well as referencing the Dutch Urgenda judgment.

Relevant interim developments:

On 12 June 2023, it was announced that the National Human Rights Commission of Korea had decided to submit an opinion to South Korea’s Constitutional Court to oppose the country’s Carbon Neutrality Act (2021), which it considered to be unconstitutional and in violation of the fundamental rights of future generations because it sets out a greenhouse gas emissions reductions target that was too low. The Act sets out a 40% emissions reductions target by 2030 as compared to 2018 levels. This, the Commission found, did not respect the constitutional principle of equality, because it passed the burden of greenhouse gas emissions on to future generations.

Consolidation with three other cases:
The South Korean Constitutional Court decided to consolidate its first four climate cases (Do-Hyun Kim et al. v. South Korea, Woodpecker et al. v. South Korea (Baby Climate Litigation), Climate Crisis Emergency Action v. South Korea (a.k.a. Byung-In Kim et al. v. South Korea) (the present case) and Min-A Park v. South Korea). Public hearings in the cases were held on 23 April 2024 and 21 May 2024.

These cases all alleged that the government’s inadequate greenhouse gas reduction targets violated citizens’ fundamental rights, particularly those of future generations. Together, the four cases comprised over 250 plaintiffs, including civil society, youth and children. The Constitutional Court issued a joint ruling in these cases on 29 August 2024.

Judgment of the constitutional court:
On 29 August 2024, the South Korean Constitutional Court found a violation of constitutional rights in this case and three related cases. In an unanimous ruling, hailed as “the first decision of its kind in Asia“, the court found that the government’s response to the climate crisis was inadequate and threatened constitutional rights, noting that the country lacked legally binding long-term emissions reductions targets for the post-2031 period, which violated the constitutional rights of future generations by shifting an excessive reductions burden to the future. The court gave government and legislature 18 months (until 28 February 2026) to introduce the relevant targets.

In particular, the Court ruled that Article 8(1) of the South Korean Carbon Neutrality Basic Act was unconstitutional. Previously, the government had pledged a 40% reduction of its GHG emissions by 2030 compared to 2018 levels, but had failed to set any targets since. The Constitutional Court held that this “does not have the minimum character necessary as a protective measure corresponding to the dangerous situation of the climate crisis”, citing the “principle of non-underprotection”, which means that the State must take appropriate measures to effectively protect the constitutional rights of its citizens.

Simultaneously, the Court held that the government’s target for 2030 did not infringe constitutional rights.

Climate Advisory Opinion of the IACtHR (OC 32/2025)

Summary:
On 3 July 2025, the Inter-American Court of Human Rights (IACtHR) issued its long-awaited advisory opinion on climate change, at the request of the governments of Chile and Colombia.

Advisory opinion request:
On 9 January 2023, Colombia and Chile jointly filed a request for an advisory opinion on the climate emergency and human rights to the IACtHR. The two governments requested clarification of the scope of States’ obligations, both in their individual and collective dimensions, in responding to the climate emergency within the framework of international human rights law, taking into account the different effects that climate change has on people in different regions and on different population groups, nature and human survival. The governments asked the Court to answer a series of questions grouped into six thematic areas, namely on:

A. The scope of States’ obligations to protect and prevent, including regarding their obligations to mitigate, adapt, regulate and monitor, and their response to loss and damage;

B. States’ obligations to protect the right to life given the existing climate science, and taking into account the right of access to information and transparency of information, including under the Escazú Agreement;

C. States’ obligations with respect to the rights of children and new generations, given especially the vulnerability of children;

D. On the State’s obligations concerning consultative and judicial procedures, taking into account the limited remaining carbon budget;

E. The protective and preventative obligations concerning environmental and land rights defenders, as well as women, indigenous peoples and Afro-descendant communities; and

F. Shared and differentiated obligations and responsibilities in terms of the rights of States, the obligation of cooperation and given the impacts on human mobility (migration and forced displacement of people).

Extended summary of the request:
In their request to the IACtHR, the two governments submitted that they are already dealing with the consequences of the climate emergency, including the proliferation of droughts, floods, landslides and fires. These, they submitted, underscore the need for a response based on the principles of equity, justice, cooperation and sustainability, as well as human rights. The two governments noted that climate change is already putting humans and future generations at risk, but that its effects are not being experienced uniformly across the international community. Instead, given their geography, climatic conditions, socioeconomic conditions and infrastructure, they are particularly being felt in the most vulnerable communities, including several countries in the Americas. They emphasized that these effects are not proportionate to these countries’ and communities’ contribution to climate change.

The governments, in their request, emphasized the relevance of the right to a healthy environment, as well as other interrelated substantive and procedural rights (affecting life, human survival and future generations). They reviewed the existing scientific evidence concerning the impacts and progression of climate change from the IPCC, and noted the vulnerability of the Andean region. The two governments referred to the 2017 Advisory Opinion of the IACtHR, which recognized the right to a healthy environment as an autonomous and individual right, and referred to the negative effects of climate change. However, they argued, there is a need to further clarify the human rights impacts of climate change, and corresponding obligations. In this regard, they raised the existence also of collective rights for the protection of nature under international human rights and environmental law, and cited the need to protect fundamental biomes like the Amazon and to understand States’ shared but differentiated responsibilities in a way that copes with loss and damage. The two governments invited the Court to set out clear standards against the background of litigation and related developments.

Consultation procedure:
In accordance with the Rules of Procedure of the IACtHR (Art. 73(3)), all interested parties (individuals and organizations) are invited to present a written opinion on the issues covered in the advisory opinion request. The President of the Court has established 18 August 2023 as the deadline for doing so. More information is available here.

Advisory opinion of 3 July 2025:
On 3 July 2025, following an oral hearing, the IACtHR issued its advisory opinion in these proceedings (in Spanish, with the text in English to follow). In a 234-page opinion, the Court addressed the questions raised by the governments of Chile and Colombia in their request.

The advisory opinion covers a wide range of relevant issues and obligations, and provides in-depth clarifications of the legal issues raised. It covers, in short:

  • The procedure, competence of the Court and admissibility of the request, as well as a number of other preliminary considerations, including about the (scientific and other) sources used by the Court and the scope of the opinion.
  • The facts of the climate emergency, including its causes, differential contributions of different actors, and its impacts on natural systems, humans, vulnerable territories and ecosystems, as well as the need for urgent action, the possibilities and need for mitigation, the need for adaptation, and the seriousness of climate impacts.
  • The complexity of required responses, including discussions of resilience and sustainable development as a vehicle for protection of both human rights and the environment.
  • The international legal framework around climate change, applicable norms and frameworks, including international investment law, human rights, international environmental law and climate change treaties. The Court also reviewed the case-law of other adjudicators in the context of climate change.
  • The obligations of States in the context of the climate emergency, including the scope of human rights obligations to respect rights, protect rights (including a reinforced due diligence obligation), and the obligation to take measures to ensure progressive realization of economic, social and cultural rights. This includes discussion of various substantive rights, including particularly the right to a healthy environment but also the rights to life, physical integrity, health, private and family life, property and home, freedom of movement and residence, water and food, work and social security, culture and education. The advisory opinion also includes consideration of procedural rights and the link between these rights and democracy, the right to science and recognition of local knowledge, the right of access to information (and combatting disinformation), the right to political participation and access to justice as well as protection of environmental defenders and equality and non-discrimination norms. In this latter regard, the opinion considers the differential protection owed to children and youth, to Indigenous and tribal peoples, Afrodescendant communities, peasants and those involved in fisheries. It also considers the differential effect of climate change and the implications for fight against poverty.

Opinion of the Court:
Appended to the Court’s extensive consideration of the relevant issues and obligations is its concrete opinion, which reads as follows (translation from the original Spanish, to be replaced with the English-language translation by the Court once available):

THE COURT DECIDES
Unanimously, that:

It is competent to issue the present Advisory Opinion, in the terms of paragraphs 14 to 23.

AND IS OF THE OPINION
Unanimously, that:

  1. According to the best available science, the current situation constitutes a climate emergency due to the accelerated increase in global temperature, produced by diverse activities of anthropogenic origin, undertaken unequally by the States of the international community, which incrementally affect and seriously threaten humanity and, especially, the most vulnerable people. This climate emergency can only be adequately addressed through urgent and effective actions for mitigation, adaptation and progress towards sustainable development, articulated with a human rights perspective, and under the prism of resilience, in the terms of paragraphs 183 and 205 to 216.

    Unanimously, that:
  2. By virtue of the general obligation to respect rights, States have the obligations indicated in paragraphs 219 to 223.

    Unanimously, that:
  3. Under the general obligation to ensure rights, States have an obligation to act in accordance with a standard of enhanced due diligence to counteract the human causes of climate change and protect people under their jurisdiction from climate impacts, in particular those who are most vulnerable, in the terms of paragraphs 225 to 237.

    By six votes in favor and one against, that:
  4. By virtue of the general obligation to ensure the progressive development of economic, social, cultural and environmental rights, States must allocate the maximum available resources to protect persons and groups who, because they are in situations of vulnerability, are exposed to the most severe impacts of climate change, in the terms of paragraphs 238 to 243.
    Judge Patricia Pérez Goldberg dissents.

    Unanimously, that:
  5. By virtue of the general obligation to adopt domestic law provisions, States must integrate into their domestic legal framework the necessary regulations to ensure the respect, guarantee and progressive development of human rights in the context of the climate emergency, in the terms of paragraphs 244 to 246.

    Unanimously, that:
  6. By virtue of the obligation to cooperate, the States are obliged to cooperate in good faith to advance in the respect, guarantee and progressive development of human rights threatened or affected by the climate emergency, in the terms of paragraphs 247 to 265.

    By four votes in favor and three against, that:
  7. The recognition of Nature and its components as subjects of rights constitutes a normative development that makes it possible to reinforce the protection of the integrity and functionality of ecosystems in the long term, providing effective legal tools in the face of the triple planetary crisis and facilitating the prevention of existential damage before it becomes irreversible. This conception represents a contemporary manifestation of the principle of interdependence between human rights and the environment, and reflects a growing trend at the international level aimed at strengthening the protection of ecological systems against present and future threats, in accordance with paragraphs 279 to 286.
    Judge Nancy Hernández López, Judge Humberto Sierra Porto and Judge Patricia Pérez Goldberg dissenting.

    By four votes in favor and three against, that:
  8. By virtue of the principle of effectiveness, the imperative prohibition of anthropogenic conducts that may irreversibly affect the interdependence and vital balance of the common ecosystem that makes the life of the species possible constitutes a norm of jus cogens, in accordance with paragraphs 287 to 294.
    Judge Nancy Hernández López, Judge Humberto Sierra Porto and Judge Patricia Pérez Goldberg dissenting.

    By a vote of five in favor and two partially against, that:
  9. The right to a healthy climate, understood as a component of the right to a healthy environment, protects in its collective dimension the present and future humanity, as well as Nature, in the terms of paragraphs 298 to 316.
    Judge Nancy Hernández López and Judge Patricia Pérez Goldberg dissenting in part.

    By six votes in favor and one partially against, that:
  10. By virtue of the right to a healthy climate, States must protect the global climate system and prevent human rights violations derived from its alteration. Therefore, they must mitigate GHG emissions, which implies (i) adopting regulations on the matter that define a mitigation goal and a mitigation strategy based on human rights, as well as regulating the behavior of companies, in the terms of paragraphs 323 to 351; (ii) adopting mitigation supervision and control measures, in the terms of paragraphs 352 to 357, and (iii) determining the climate impact of projects and activities when appropriate, in the terms of paragraphs 358 to 363.
    Judge Patricia Pérez Goldberg dissenting in part.

  12. By virtue of the rights to life, personal integrity, health, private and family life, property and housing, freedom of residence and movement, water and food, work and social security, culture and education, as well as all other substantive rights threatened by climate impacts, States have an enforceability obligation, States have an immediately enforceable obligation to define and update, as ambitiously as possible, their national adaptation goal and plan, in the terms of paragraphs 384 to 391, as well as the duty to act with enhanced due diligence in compliance with the specific duties set forth in paragraphs 400 to 457.
    Judge Patricia Pérez Goldberg dissenting in part.

    Unanimously, that:
  13. By virtue of the democratic principle, the States must strengthen the democratic rule of law as an essential framework for the protection of human rights, the effectiveness of public action, and open and inclusive citizen participation, also ensuring the full exercise of procedural rights, in the terms of paragraphs 460 to 469.

    By six votes in favor and one partially against, that:
  14. By virtue of the human right to science and the recognition of local, traditional and indigenous knowledge, protected by Articles 26 of the Convention and 14.2 of the Protocol of San Salvador, all persons have the right to access the benefits of measures based on the best available science and on the recognition of local, traditional or indigenous knowledge, in the terms of paragraphs 471 to 487.
    Judge Patricia Pérez Goldberg dissenting in part.

    Unanimously, that:
  15. Under the right of access to information, States have obligations regarding (i) production of climate information, in the terms of paragraphs 501 to 518; (ii) disclosure of information relevant to the protection of human rights in the face of climate change, in the terms of paragraphs 519 to 523, and (iii) to adopt measures against disinformation, in the terms of paragraphs 524 to 527.

    Judge Nancy Hernández López, Judge Humberto Sierra Porto and Judge Patricia Pérez Goldberg dissenting in part.

    Unanimously, that:
  18. By virtue of the right to defend human rights, States have a special duty to protect environmental defenders that translates into specific obligations, among others, to protect them, investigate and, if necessary, punish attacks, threats or intimidations they suffer, and to counteract the “criminalization” of the defense of the environment, in the terms of paragraphs 566 to 567, and 575 to 587.

    Unanimously, that:
  19. States should adopt measures aimed at addressing the way in which the climate emergency exacerbates inequality and has a differentiated impact on people living in multidimensional poverty, in the terms of paragraphs 626 and 627.

    By four votes in favor and three partially against, that:

Children and young people Domestic court Emissions reductions/mitigation Imminent risk Non-discrimination Paris Agreement Right to a healthy environment Right to life South Korea

Do-Hyun Kim et al. v. South Korea

Summary:
On 13 March 2020, nineteen teenagers from across South Korea initiated proceedings against their government (the National Assembly of Korea and the President of Korea), arguing that insufficient emissions reductions efforts were violating their constitutional rights. They alleged that Korean climate legislation (originally Article 42(1)1 of the Framework Act on Low Carbon, Green Growth, and later also Article 8(1) of the domestic Carbon Neutrality Act (the “Carbon Neutrality and Green Growth Act” of 2021) was not compatible with their constitutional rights, bringing their case against the National Assembly for enacting the law and the government for implementing an administrative plan based on that law. Their constitutional complaint was combined with three other mitigation cases and decided by the Constitutional Court of the Republic of Korea on 29 August 2024.

The applicants in this case are part of the Korean Youth 4 Climate Action Group, which has led the Korean ‘School Strike for Climate’ movement. They argued that, by not taking action to prevent the threats posed by climate change, the government had violated the right of younger generations to life and the pursuit of happiness (Article 10 of the Constitution), which they argue also enshrines the right to resist against human extinction, along with the right to live in a healthy and pleasant environment (Article 35(1) of the Constitution). They also contested inter-generational inequalities under the constitutional prohibition of discrimination (Article 11 of the Constitution) and invoked the duty of the State to prevent environmental disasters (Article 34(e) of the Constitution). In doing so, the applicants invoked the fatal risk posed by climate change and the irrevocable damage to be suffered by younger generations. As a major emitter of greenhouse gas emissions, they argued, Korea has an obligation to protect its citizens from the effects of climate change by taking stronger emissions reductions action.

Relevant interim developments:
On 30 December 2022, the Korean National Human Rights Commission issued an official statement to the President of Korea regarding climate change and human rights. Citing IPCC reports, UN findings, other instances of climate litigation (such as Urgenda and Neubauer) and the existence of different vulnerabilities, it found that “[a]s the climate crisis has far-reaching impacts on multiple human rights, including the rights to life, food, health and housing, the government should regard protecting and promoting the rights of everyone in the midst of climate crisis as its fundamental obligation and reform related laws and systems to address the climate crisis from a human rights perspective.”

On 12 June 2023, it was announced that the National Human Rights Commission of Korea had decided to submit an opinion to South Korea’s Constitutional Court to oppose the country’s Carbon Neutrality Act (2021), which it considered to be unconstitutional and in violation of the constitutional rights of future generations because it sets out a greenhouse gas emissions reductions target that was too low. The Act sets out a 40% emissions reductions target by 2030 as compared to 2018 levels. This, the Commission found, did not respect the constitutional principle of equality, because it passed the burden of greenhouse gas emissions on to future generations.

Consolidation with three other cases:
The South Korean Constitutional Court decided to consolidate its first four climate cases (Do-Hyun Kim et al. v. South Korea (the present case), Woodpecker et al. v. South Korea (Baby Climate Litigation), Climate Crisis Emergency Action v. South Korea (a.k.a. Byung-In Kim et al. v. South Korea) and Min-A Park v. South Korea. Public hearings in the cases were held on 23 April 2024 and 21 May 2024.

These cases all alleged that the government’s inadequate greenhouse gas reduction targets violated citizens’ fundamental rights, particularly those of future generations. Together, the four cases comprised over 250 plaintiffs, including civil society, youth and children. The Constitutional Court issued a joint ruling in these cases on 29 August 2024.

Judgment of the constitutional court:
On 29 August 2024, the South Korean constitutional court ruled. It found a violation of constitutional rights in this case and three related cases. In an unanimous ruling, hailed as “the first decision of its kind in Asia“, the court found that the government’s response to the climate crisis was inadequate and threatened constitutional rights, noting that the country lacked legally binding long-term emissions reductions targets for the post-2031 period, which violated the constitutional rights of future generations by shifting an excessive reductions burden to the future. The court gave government and legislature 18 months (until 28 February 2026) to introduce the relevant targets.

In particular, the Court ruled that Article 8(1) of the South Korean Carbon Neutrality Basic Act was unconstitutional. Previously, the government had pledged a 40% reduction of its GHG emissions by 2030 compared to 2018 levels, but had failed to set any targets since. The Constitutional Court held that this “does not have the minimum character necessary as a protective measure corresponding to the dangerous situation of the climate crisis”, citing the “principle of non-underprotection”, which means that the State must take appropriate measures to effectively protect the constitutional rights of its citizens.

Simultaneously, the Court held that the government’s target for 2030 did not infringe constitutional rights.

Status of the case:
Decided. On 29 August 2024, the South Korean constitutional court found a violation of the constitutional rights of future generations in this case.

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.

ENVironnement JEUnesse v. Canada

Summary:
In 2018, the environmental NGO ENvironnement JEUnesse applied for leave to bring a class action case against the Canadian government on behalf of citizens of Québec aged 35 and under. The NGO sought a declaration from that the Canadian government had violated its obligation to protect these citizens’ fundamental rights under the Canadian Charter of Rights and Freedoms and the Québec Charter of Rights and Freedoms by setting insufficent greenhouse gas reduction targets and by failing to create an adequate plan to reach these targets. Specifically, they invoked their rights to life, to a healthy environment, and to equality. On 11 July 2019, the Superior Court of Quebec dismissed the motion to authorize the institution of a class action, finding that the proposed class, with its 35-year age limit, had been created arbitrarily. An appeal by ENVironnement JEUnesse was denied on 13 December 2021.

Remedies sought:
As well as a declaratory judgment, the NGO sought punitive damages and an order to cease interference with the plaintiffs’ rights.

Judgment:
In their judgment of 13 December 2021, the three judges of the Court of Appeal dismissed the appeal and denied the certification of the proposed class. They referred to the role of the legislature in making the complex social and economic choices required here. They also considered that the remedies sought by the applicants were not specific enough to be implemented by a court. Lastly, the judges upeld the previous instance’s finding concerning the arbitary constitution of the class, with its 35-year age limit.

Further procedural steps:
The applicants announced that they would launch an appeal to the Supreme Court of Canada.

Woodpecker et al. v. South Korea (‘Baby Climate Litigation’)

Summary:
In June 2022, a climate case was filed in South Korea by sixty-two babies and children under the age of 11, including a 20-week-old fetus nicknamed “Woodpecker”, who was born after the proceedings were launched. The claimants submitted that the State was violating the rights of future generations by failing to reduce its greenhouse gas emissions. At the time of filing, this was the fourth climate case challenging the constitutionality of the Korean climate policy, as contained in the country’s 2021 Carbon Neutrality Act (2021). In this case, the claimants argue that the mitigation measures set out in this Act (envisioning a 40% reduction of greenhouse gas emissions by 2030 as compared with 2018 levels) violates their constitutional rights to life, equality, property, and to live in a healthy and pleasant environment. To do so, they extensively discuss IPCC reports and successful domestic climate litigation in other jurisdictions (particularly the Urgenda and Neubauer judgments).

More specifically, the plaintiffs contested Article 3(1) of the 2022 Enforcement Decree of the 2021 domestic Carbon Neutrality Act, arguing that this provision was unconstitutional because it violated:

  • their right to life, pursuit of happiness and general freedom of action (Article 10 of the South Korean Constitution, ‘Guarantee of Human Dignity and Fundamental Rights’);
  • their right to equality (Article 11 of the Constitution);
  • their right to property (Article 23 of the Constitution);
  • thir right to live in a healthy and pleasant environment (Article 35 of the Constitution); and
  • the state’s obligation to prevent disasters and protect the people from the risk of environmental disasters (Article 34(6) and Article 35(2) of the Constitution).

According to the Guardian, this was the first climate case in which a foetus was listed as a claimant. Together, the four cases reportedly represent the first findings of their kind in Asia (i.e. the first time that a court has find that inadequate mitigation action violates fundamental rights).

Relevant developments:
On 12 June 2023, it was announced that the National Human Rights Commission of Korea had decided to submit an opinion to South Korea’s Constitutional Court to oppose the country’s Carbon Neutrality Act (2021), which it considered to be unconstitutional and in violation of the fundamental rights of future generations because it sets out a greenhouse gas emissions reductions target that was too low.

Luca Salis et al. v. Sachsen-Anhalt

Summary:
This constitutional complaint was brought by three young people against the German State (“Bundesland”) of Sachsen-Anhalt in the wake of the Neubauer v. Germany judgment of the German Bundesverfassungsgericht. It is one of ten separate constitutional complaints and one subsidiary popular complaint supported by the NGO Deutsche Umwelthilfe against ten Bundesländer. They contest the State’s failure to chart a course towards greenhouse gas emissions reductions by adopting legislation on climate protection. The state abandoned efforts to adopt such a law after an initiative in this regard failed in 2013, relying on the Paris Agreement and the German Constitution. Like in the eleven related cases, the plaintiffs here argue that the Bundesländer share responsibility for protecting their lives and civil liberties, along with those of future generations, within their respective spheres of competence. According to the plaintiffs, the lack of legislation on climate action on the state level violates the German Constitution and the reductions regime under the Paris Agreement. They also submit that they have a fundamental right to defend themselves against future rights impacts caused by the lack of climate measures.

On 18 January 2022, the First Senate of the Federal Constitutional Court dismissed all eleven complaints for lack of adequate prospects of success. In alignment with its argumentation in Neubauer v. Germany, the First Senate recognized that the burden of CO2 emissions reductions must not be unilaterally offloaded onto future generations. However, the First Senate stated the individual legislators of the Bundesländer have not been been given an overall reduction target to comply with, even at the expense of freedom protected by fundamental rights. Thus, according to the First Senate’s decision, a violation of the obligations to protect the complainants from the dangers of climate change cannot be established. As regards to the Bundesländer, the First Senate clarified that they still have a responsibility to protect the climate, particularly by virtue of Article 20a of the German Constitution.

Rights invoked:
The applicants invoked violations of freedoms guaranteed under the domestic Constitution, especially those in Art. 2(2) of the German Constitution (right to life and physical integrity and freedom of the person), in combination with Article 20a of the Constitution (protection of the natural foundations of life and of animals). They invoked these rights in their ‘intertemporal dimension’, i.e. taking on the framing of the Neubauer case, which considered that failure to act now on climate change means excessively impacting future freedoms.

Marlene Lemme et al. v. Bayern

Summary:
This case is one of ten separate constitutional complaints and one subsidiary popular complaint supported by the NGO Deutsche Umwelthilfe against ten German States (“Bundesländer”). It was brought by ten youth plaintiffs concerning the codification of the adjusted climate goals brought about in response to the Neubauer v. Germany judgment of the German Bundesverfassungsgericht. According to the applicants, in their constitutional claim, the German States (“Bundesländer”) share responsibility for protecting their lives and civil liberties, along with those of future generations, within their spheres of competence. They argue that the lack of legislation on climate action on the state level violates the German Constitution and the reductions regime under the Paris Agreement, and that they have a fundamental right to defend themselvse against future rights impacts caused by the lack of climate measures.

The Bavarian Climate Protection Act (Bayerisches Klimaschutzgesetz) aims to reduce greenhouse gas emissions by 55% compared to 1990 levels by 2030. It also aims to achieve net zero emissions by 2050, and requires Bavaria to offset emissions after 2030. This has been implemented through a climate protection program. According to the plaintiffs, the lack of a deadline of adaptation strategy, and the failure to provide differentiated targets or instruments for implementation of compliance, mean that the Bavarian law falls short of the Federal requirements on climate protection measures.

On 18 January 2022, the First Senate of the Federal Constitutional Court dismissed all eleven complaints for lack of adequate prospects of success. In alignment with its argumentation in Neubauer v. Germany, the First Senate recognized that the burden of CO2 emissions reductions must not be unilaterally offloaded onto future generations. However, the First Senate stated the individual legislators of the Bundesländer have not been been given an overall reduction target to comply with, even at the expense of freedom protected by fundamental rights. Thus, according to the First Senate’s decision, a violation of the obligations to protect the complainants from the dangers of climate change cannot be established. As regards to the Bundesländer, the First Senate clarified that they still have a responsibility to protect the climate, particularly by virtue of Article 20a of the German Constitution.

Rights invoked:
The applicants invoked violations of various freedoms guaranteed under the domestic Constitution, especially those in Art. 2(1) of the German Constitution (right to free development of one’s personality), in combination with Article 20a of the Constitution (protection of the natural foundations of life and of animals). They invoked these rights in their ‘intertemporal dimension’, i.e. taking on the framing of the Neubauer case, which considered that failure to act now on climate change means excessively impacting future freedoms.

Date of decision:
18 January 2022

Related proceedings:
In addition to the constitutional proceedings, a subsidiary popular complaint has been brought by the same group of applicants to contend that the Bavarian Climate Protection Act (Bayerisches Klimaschutzgesetz), along with the wider regulatory context, is in violation of constitutional rights.
