30 winning Climathon solutions that could change the world!

More than 100 cities gathered this year to take part in the world’s largest climate action hackathon on 27 October 2017.

Thousands of people in major cities across the world united to accelerate our ability to respond to climate change on a global scale.

Organised by Climate-KIC, the EU’s initiative for climate innovation, Climathon brings together the challenges of the world’s cities with the people who have the passion and ability to solve them.

Each city participating in the global Climathon works on a climate change challenge that reflects what affects local urban life most. 

Anything from air pollution and waste management to transport and bio diversity is given the Climathon treatment. Below, you can find some of the best winning solutions that came out of Climathon this year.

Meet some Climathon winning teams!
