The climate hackathon, Climathon brings together the challenges of the world’s cities with the people who have the passion and ability to solve them.

Each city sets up scenarios reflecting their local urban climate challenges, including Urban Planning, Infrastructure, Housing, Water Use, Waste Removal, City Satellite Data, and more.

1. Solve real issues for your city.

2. Promote your idea nationally and internationally.
