At Impact Hub, we aim at making Geneva healthier and more sustainable. With this objective in mind, every year we co-organize with eqlosion the Climathon Geneva.


  • The objective of Climathon Geneva is to support the Cantonal Climate Plan, by bringing together citizens and organizations from the private and public sectors around the issue of climate change, in order to promote innovative solutions and support the creation of new projects.


  • The three challenges of this year’s Climathon are directly linked to the canton’s ambition to reduce its environmental footprint, notably by reducing greenhouse gas emissions by 60% by 2030 compared to 1990, and to aim for carbon neutrality by 2050.

What to expect for these 24 hours?


In teams of 4 to 5 people, you will follow a “Design Thinking” process, a human-centered innovation management methodology initiated at Stanford University, and you will be asked to support your concept in a pitch format.


Validated by a jury of local experts, the winning teams’ solutions are intended to be deployed on a real scale, with the support of the organisers and partners.

The challenges of the past 2021 edition:

📌 Challenge 1
“Imagining Geneva’s carbon-neutrality in 2050″

Despite the growing number of solutions for achieving carbon neutrality, the scale of the work required to reach this goal remains elusive.

It is therefore more than necessary to imagine what a world where humans emit virtually no greenhouse gases will look like in the future. 

After having consulted experts, the Canton is now turning to its citizens to imagine possible futures. It invites you to create and share your vision of a carbon-neutral future in 2050 during the 2021 edition of the Geneva Climathon.

Shifting polluting activities to less carbon-intensive sectors or changing social norms and consumption behaviours, you can move in the direction that speaks to you most in order to hack this challenge.

📌 Challenge 2
“Second-hand market: an opportunity to promote sustainable fashion”

The fashion industry generates about the same emissions as the entire global airline industry.  

The secondhand / vintage sector is increasingly challenged – and plays an important role – in providing solutions to reduce the global waste of natural resources and to reduce its CO2 footprint. 

With this challenge, you will have the opportunity to look at the circular economy, including sustainable fashion, through the second-hand market. More precisely, you will explore and find new ways to get more people interested in and excited about secondhand fashion. 

Through ideation, the objective is to find new solutions that keep vintage clothing into active use and thus reduce the need for new goods to be produced in the first place.  

📌 Challenge 3
“The Citizen Challenge”

With its 3 themes submitted to a crowdfunding process, in partnership with SIG-Impact, the Citizen’s Challenge gives voice to the citizens of Geneva so that you can decide your climate priority.

Support one of the 3 themes of this challenge :

  1. Urban agriculture in Geneva: the solution for the climate and social integration?
  2. How to engage Geneva’s major actors in the fight against climate change?
  3. What role can blockchains play in achieving the Sustainable Development Goals?

The challenge that first reaches the 100% funding target will become THE Citizen Challenge to hack at the 2021 edition of the Geneva Climathon.
