Climate Week-3 (CW3) will take place from 21 to 25 April 2026 in Yeosu, Republic of Korea.
The event is part of the UNFCCC Climate Weeks series, which support the implementation of the UN Framework Convention on Climate Change and the Paris Agreement by connecting intergovernmental processes with practical climate action.
CW3 will bring together Party representatives and a wide range of stakeholders from the region and beyond, including businesses, financial institutions, cities, civil society organizations, and international partners. The event provides a platform for dialogue, collaboration, and the exchange of practical solutions that support the implementation of climate commitments and advance climate action on the ground.
The programme includes a number of UNFCCC mandated events, which are organized in accordance with their respective mandates under the Conference of the Parties and the Paris Agreement bodies. Information on nomination and registration procedures for these events is shared directly with Parties, observer organizations and UN/IGO institutions.
In addition, the programme includes public components such as the Implementation Forum, which focuses on practical and solution-oriented discussions bringing together policymakers, private sector actors, local authorities, youth and civil society to explore ways to accelerate climate implementation.
While mandated events are reserved for Party representatives, members of the media and registered participants are welcome to attend the open components of Climate Week Yeosu, including the opening session, the Implementation Forum sessions, and the closing segment presenting key outcomes.
Participation in the open components of Climate Week Yeosu is free of charge. Participants are responsible for their own travel arrangements and related costs, including flights and accommodation.
