This month, 141 countries voted at the UN General Assembly to support the International Court of Justice’s advisory opinion on climate duties. Secretary-General Guterres proudly stated, “The world’s highest court has spoken.” This moment is more than just a statement; it marks a significant change in how we view climate action, with real-world consequences for governments everywhere.
For years, commitments to protect the environment were seen as political choices. Without legal backing, governments could ignore or shift these responsibilities based on elections. However, a new wave of court rulings is changing this perspective. These decisions are turning political promises into legal obligations.
In recent rulings, courts have made it clear that inadequate climate action is a violation of rights. For example, in April 2024, the European Court of Human Rights ruled that Switzerland failed to protect its citizens’ right to a private life due to poor climate measures. In May 2025, the International Court of Justice (ICJ) declared that climate change is an urgent threat. It stated that countries must adhere to the 1.5°C target set by the Paris Agreement. Failure to do so could lead to reparations.
These cases show a growing legal framework holding governments accountable for climate action. According to a report by the Grantham Research Institute, there are over 2,900 climate-related legal cases worldwide. This indicates that the courtroom is becoming a vital space for ensuring government accountability on climate issues.
The impact of these rulings is most significant for five groups:
Vulnerable Nations: Small island countries, facing dire climate impacts, can now hold major polluters accountable more effectively. The reparation framework introduced by the ICJ helps these nations in their fight for justice.
Electoral Bodies: Elections have increasingly been disrupted by climate events. In 2024, at least 23 elections were affected by extreme weather. Many electoral bodies lack the legal and operational safeguards to manage these disruptions.
National Legislatures: Governments must now align domestic laws with international climate commitments, which shifts the legal landscape for legislators.
Human Rights Institutions: These bodies are pivotal in translating legal climate obligations into national action. Their effectiveness relies on their independence and capacity to hold governments accountable.
Judicial Systems: Courts are receiving more climate-related cases demanding clarity on laws related to damages caused by climate change.
Despite these advancements, there remains a significant gap between legal rulings and their real-world application. Legalities alone cannot drive change without robust democratic institutions to enforce them. This means that parliaments, courts, and human rights bodies need to work together effectively.
The political landscape presents challenges. Environmental policies often result in short-term sacrifices for long-term benefits, making them politically unappealing. Additionally, fossil fuel industries exert pressure on political agendas, complicating reform efforts.
International IDEA is focusing on bridging this gap. They emphasize that political issues, not just legal ones, hinder progress in climate action. The organization provides support aimed at fostering democratic innovation in climate policy, such as empowering citizen assemblies to enhance public participation in difficult decision-making.
As climate change poses growing threats, it is essential to strengthen not just legal frameworks but also democratic institutions capable of implementing them. The question now is whether the global community can match the urgency of legal expectations with institutional development.
By addressing these challenges, we can ensure that courts’ rulings lead to meaningful action on climate change, benefiting not just the present but also future generations.
