Tackle climate change from the ground up


We are a global community of climate-minded people working together to help our cities decarbonise.

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.
