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.
