Why 2 tonnes?


Average emissions per French (tCO2e / pers. / Year)

Copie de Schéma de 11t à 2t.png

In 2050 :

2 tonnes

2 tonnes of CO2e equivalent per year is the amount of greenhouse gases emitted per person in a CO2 neutral world.

It is also the objective to be reached by 2050 in order to respect the commitments of the Paris Agreement : to keep the increase in global temperature at a level below 2 degrees.

Today, on average, each French person emits 9,5 tCO2e / year .

   "But what can be done to reduce it?

How to act effectively for the climate? "

Today :

9,6 tonnes

Which individual actions to prioritize?

Légumes organiques


Voiture électrique

Buy local or use an electric car?

What collective actions to invest in?




Deploy anaerobic digestion or wind turbines?

How to influence the debates and affect the others?




Raising awareness or acting for the Climate?


The 2tonne workshop invites participants to explore the future in teams and try to limit climate change by reaching the 2tonnes per year per person by 2050.


To allow a systemic understanding of the issues, the workshop takes into account the individual and collective dimensions of the subject, without forgetting the role of influence, a key issue in the transformation of society.


Aimed at both novices and experts on the subject of climate change, it is also a real serious game, designed to bring people together and debate together, so that everyone can have fun and express their opinions.


Have you always dreamed of putting yourself in the shoes of a Minister, or talking about the climate with Donald Trump? Take part in the game!


Your goal is ambitious, but your budget is limited! Will you be able to make the right choices?
