By September 2025, Switzerland must deliver:
✅ A clear, enforceable CO₂ ordinance
✅ A transparent national methodology for emissions reductions
✅ A quantified carbon budget or equivalent framework
✅ Adaptation measures and procedural safeguards

Switzerland still has to prove that its climate policies are strong enough to align with the 1.5°C global warming limit. Switzerland must now prove that its climate policies align with the 1.5°C warming limit—and that means more than vague promises.

✅ Customary international law emerges from consistent state practice & a belief that such practice is legally obligatory. Given the near-universal recognition of the right to a healthy environment & its link to other fundamental rights, its customary status is both legally & morally compelling.

✅ Recognition in international instruments: From the 1972 Stockholm Declaration to the Rio & Johannesburg Declarations, key international texts have consistently acknowledged this right. In 2022, the UNGA recognized it as fundamental, with overwhelming state support (161 votes in favor, 0 against).

✅ Widespread State practice : a vast majority of states have already recognized the right to a healthy environment, through international agreements or their own legal systems. 100+ countries have enshrined this right at the constitutional level, making it a cornerstone of their legal frameworks.

As we outlined in our amicus curia brief, there are strong legal grounds for asserting that this right has acquired customary international law status:

We demand States & the @coe.int ensure that Switzerland respects the judgment & meaningfully address the #ClimateCrisis.

30+ organizations are calling on Switzerland to step up & comply with the ECHR’s climate judgment to #ActOnClimate.
