World’s Youth for Climate Justice (WYCJ) led a years-long global campaign to take climate change and human rights to the International Court of Justice (ICJ) to get an advisory opinion (AO) – and with success! On 23 July 2025, the ICJ delivered a historic climate ruling outlining States' obligations under international law regarding climate change. The Court set out the applicable law governing States' duties to address climate change and the legal consequences of inaction.
One year later, as governments, courts, civil society, communities, and advocates begin translating the ICJ AO and other landmark climate rulings into action, one question remains: what comes next?
World’s Youth for Climate Justice is bringing law from paper to people, for communities and generations to come. Through strategic legal interventions and litigation, youth capacity-building & coordination, and legal and policy framework implementation, we are advancing the implementation of the historic climate ruling from the world’s highest court.
