To tackle the climate crisis we need to keep fossil fuels in the ground. But governments that phase out coal, end gas production, or stop oil pipelines can be sued by corporations in private courts and be held liable for billions in damages. How? Under the Energy Charter Treaty (ECT). It is now up to European governments and the European Commission to pull out of the anti-climate ECT and stop its expansion to even more countries. Take action today to make this happen!


To European governments, parliaments, and EU institutions:

Pull out of the Energy Charter Treaty and stop its expansion to other countries! The treaty allows coal, oil, and gas corporations to obstruct the transition to a clean energy system. Disarm fossil fuel firms now, so they can no longer impede urgent climate action!

Take action to end the climate-killing Energy Charter Treaty



What are we?


CliMates is an international youth-led think-and-do tank on climate change gathering together volunteers, both students and young professionals.

The goal of our NGO (non-governmental organization) is to take on the climate challenge by :

  1. Developing and promoting innovative ideas and tools


    Training youth to become change-makers



    Influencing decision-makers

Who are we?

We are youthful souls: crazy and innovative, sharing a collective vision for a transition towards a low carbon society by informing, empowering and engaging youth in collaborative research, global advocacy, and grassroots mobilization.

CliMates gathers youth from all around the world who aim at facing climate challenges. Our global network represents various countries, identities, backgrounds, and cultures.


We want to stand up, shout out, be heard, and create something different through the alliance of thought and action!

Where are we?

CliMates’ project was born in France in 2011 and has spread all around the world with members in more than 30 countries. You can join us and/or collaborate with us from everywhere!


CliMates Mali, our first local branch, was created and registered in 2015. It demonstrates CliMates’ willingness to strengthen the structure of its international network in order to share our energies, visions and tools.


Reaching out larger audiences our second local branch, CliMates Nepal was launched in 2017.


Since the beginning of 2018, CliMates also has a presence in Austria and Indonesia with the creation of its third and fourth local branch.

‘Inspiring’ is the best word to describe CliMates and why it was created : 

an intense combination of excitement and frustration.

 Henri Landes & Margot Le Guen

CliMates' co-founders

What if the 2009 Copenhagen climate negotiations on climate change (COP 15) had gone differently?


To answer this question, in June 2011, 200 students participated in a simulation of this international conference. This innovative summer school project, called COP RW (Rewind and Rewrite), was co- organized by Sciences Po and the IDDRI (Institute of Sustainable Development and International Relations). During this simulation, young participants succeeded in reaching a more ambitious agreement than the one achieved by official governments. Both awakened and frustrated by this result, Henri Landes and Margot Le Guen wanted to go further. They decided to launch a think-and-do tank focusing on climate change.
