While waiting for the 2019 registration to open, take a look at all the cities that worked hard to tackle their climate challenges during Climathon 2018.

What is Climathon?

Originally conceptualised as a 24-hour hackathon by Climate-KIC, Climathon has since taken off as a global movement, engaging citizens on climate action—and providing cities with continued support on the unique challenges they face.


Propose solutions & form teams

Citizens around the world take direct Climate action by coming up with innovative solutions to local climate change challenges.


Run experimetns to test your ideas

Students, start-ups, entrepreneurs, big thinkers and technical experts from major universities, research centers, government facilities and corporate offices around the world meet simultaneously for a 24-hour marathon session.


Present progress and win support

Teams present their solutions to a judging panel, who will determine which ideas are most appropriate for each of the available support packages.
