Climathon: Become an organiser!

Climathon events bring citizens together to raise awareness and inspire local climate action.

A Climathon event is planned and coordinated by independent organisers and organisations. It can happen in-person, hybrid or virtually, and the event typically lasts 12-48 hours where participants collaborate to tackle local climate challenges.

Climathon has been organised since 2015 with about 600 organisers, 1,000 events and over 30,000 participants worldwide.

The call to become a Climathon organiser in 2025 is now official open! This year to amplify the impact of the movement, we’re introducing some new elements:

• Climathon organisers will join Climate KIC Community, a leading network of impact professionals granting access to events, networking and learning opportunities, resources, and more. You can find more about Climate KIC Community here.
• Global Climathon Days are back! We’re asking all organisers to plan their event on the week of 6-12 October 2025.

Applications close on 31 May 2025 at 23:59 CET.
