Infographics to show what Climathon is?

Climathon is a global 24-hour climate change hackathon which will take place simultaneously in major cities around the world on 26 October 2018.

It brings together the challenges of the world’s cities with the people who have the passion and ability to solve them. Climathon attracts innovators, entrepreneurs, students and professionals to create innovative solutions to cities climate challenges.

In cities with a 24 hour Climathon event, a Young Climathon can be set up for undergraduate students with a related challenge but with shorter time frame.

Now its fourth year of operation, the Climathon movement has grown tremendously over the past three years, encouraging more innovators across the globe to drive climate action.

Climathon has grown from 19 to 104 cities in the space of two years, operating across 6 continents, reaching 33 million people worldwide in 2017.


The Climathon Challenge

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, and extreme weather events, use of city satellite data, 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 and businesses that address city climate challenges across the globe.
