Time for change, be the change. Join Climathon Lausanne!

Climate impacts are touching every part of the globe - but you know the climate challenges your community is facing the best.

Climathon is a global movement that organises locally; a city-based programme that offers a clear pathway to climate action.

Come and join the movement on February 12 and 13, 2021 - This event will take place 100% online!

At the core of the Climathon programme is a yearly ideathon that takes place in your city and in hundreds of other cities across many continents and time-zones.

Come and join a diverse group of participants, ranging from policymakers to hackers, youth to academics, students to business leaders. Together you will come to collaborate on forward-thinking ideas that tackle local climate challenges.

Take part and join a global community of thousands who want to act now, and rethink the cities we live in and the future we want as citizens.  

Ready for a unique experience? Get your chance to have an impact by taking on one of the three climate challenges provided by our Partners : 

  • Challenge 1 : Boosting the energy transition by snowball effect
  • Challenge 2 : Increasing the rate of building renovations
  • Challenge 3 : Imagine the role of the Transports publics lausannois in 2030
