Climate Weeks 2026
Building on the strong foundation laid in 2025 and past years, the 2026 Climate Weeks will continue to focus on accelerating the operationalization of decisions under the intergovernmental process into action on the ground and building momentum toward COP by facilitating targeted inputs to upcoming meetings.
In the format launched in 2025, the Climate Weeks bring together representatives of Parties and non-Party stakeholders in a global space that will combine several planned UNFCCC mandated meetings, as well as policy and high-impact dialogues, offering a unique opportunity to link the intergovernmental process and the discussions that will feed into COP with the real needs of implementation, while enabling the consolidation of activities to increase efficiency and impact.
The Climate Weeks are held twice a year in different regions, maintaining a global focus in scope and participation.
In 2026, the Climate Weeks are taking place as follows:
- Climate Week 3 was held in Yeosu, the Republic of Korea, from 21 to 25 April 2026
- Climate Week 4 will be held in Baku, Azerbaijan, from 7 - 11 September 2026
Climate weeks provide a structured yet flexible space for dialogue, capacity-building, and showcasing innovative solutions to support the intergovernmental process and urgent, inclusive, and coordinated climate action.
