How does Climathon work?

Climathon is a global 24-hour climate change hackathon which takes place simultaneously in more than 100 cities around the world on 25 October 2019. It brings together the challenges of the world’s cities with the people who have the passion and ability to solve them.

Each city sets its own local climate challenge that reflects what affects their urban life the most. Challenges can vary from air quality, water and waste management or extreme weather events, etc.

Participants then tackle the set challenge for a full 24-hours, before pitching their ideas in front of relevant local stakeholders. These ideas can develop into tangible sustainable solutions, projects and businesses that address city climate challenges across the globe.


Who runs Climathon?

Climathon was founded by Climate-KIC Europe in 2015 in the run up to the historic Paris climate negotiations and since then facilitated in Australia by Climate-KIC Australia in collaboration with our many partners.

What to expect

Free to join, we will coach you through a set of workshops, feed and entertain you for two days, and there will be great prizes for the winning teams – including the opportunity to accelerate your idea through the ClimateLaunchpad program in 2020.

Climathon attracts innovators, entrepreneurs, students and professionals to create innovative solutions to cities’ climate challenges.
