In a landmark moment for youth climate leadership, children and youth from all 10 Asean Member States formally presented the Asean Children & Youth Climate Declaration, known as the Langkawi Declaration to environment ministers during the 18th Asean Ministerial Meeting on the Environment (AMME). Speaking at the AMME, the Asean youth representatives pledged to raising awareness, driving community-based solutions, and holding themselves accountable as partners in climate action. For over three days in Langkawi, youth delegates worked together through dialogues, skills labs, and strategy sessions to craft a shared vision for the region’s climate future. The result is the Langkawi Declaration, a historic, youth-led blueprint that puts children’s rights at the heart of Asean’s climate agenda. The Langkawi Declaration aims to inform on-going national youth efforts and contribute to the region’s collective positioning ahead of COP30.
