Climathon is a worldwide movement of people who actively combat climate change. At the centre of the movement is a 24-hour climate hackathon, held in cities around the world, including Zurich. That is why this year’s Climathon Zurich is a fantastic opportunity for everybody who wants to drive Zurich’s net zero journey.

5 Challenges for 2022

Participate in Climathon 2022 and tackle one of this year’s impactful challenges together with your team


Let’s play: Gamification towards net-zero

How might we use games and gamification to incentivize citizens to join us on our net zero journey?


Better together: Empower citizens to be climate scientists

How might we enable citizens to contribute their knowledge and observations to fight climate change?


Repair: The new normal.

How might we boost and mainstream repair services in Zurich?


Potential unlocked: Rethink Zurich’s parcel stations

How might we turn the SalüBox into a lively place for goods exchange & last mile logistics?


Company challenge: Together towards net zero

Companies are invited to bring their own net-zero-relevant challenge which they want to tackle throughout Climathon.
