General information about the Climathon

Climathon offers you the chance to take action to create real solutions to your city’s climate challenges. You can also benefit from:

• Helping to make your city more resilient to climate change
• Networking with local leaders from academia, business, and public authorities
• Developing your skills in public speaking, innovative thinking, prioritisation, and exploring new tools and methodologies
• Joining forces with other like-minded entrepreneurs, students and developers
• Generating ideas and solutions to climate change that can become real-life businesses
• Becoming a part of a global community working together to take climate action!

Climathon is a global movement dedicated to solving the toughest climate challenges cities face today, which is manifested in a 24-hour hackathon taking place simultaneously in major cities around the world.

The basic process flow of the Climathon:

1. Setting the climate challenge: Cities identify their climate challenges and call on their citizens to come up with innovative solutions.
2. Coming up with solutions: Citizens, city officials, and sponsors connect under a shared vision for a healthier city, which is manifested in a 24-hour hackathon to find innovative city solutions.
3. Beyond the hackathon: Innovation happens when diverse perspectives are brought together—creating both tangible climate solutions for cities and empowered communities. Climathon is more than a hackathon, it's a movement.

The Climathon hackathon date is the 26 October 2018. As it’s a 24-hour event it will run into another day. Check your individual city page for the exact start and end time.
