Humanity must face the ecological limits of the Earth. The distribution of spaces and resources today does not allow everyone to live in dignity and happiness. In addition, the resources available per person are diminishing, and threatening a large part of current and future generations in unlivable conditions. Finally, those who have a dignified lifestyle are not necessarily happy.

It is possible to change the conditions of human life to enable all future generations to live in dignity and to be happy. These conditions are possible and favored by a little disturbed climate.

This change should reduce climate change as much as possible, ie + 1.5 ° C in 2100. It should therefore reduce our GHG emissions. For example, this mainly involves emitting on average less than 2tCO2e / person in 2050.


Getting there, or getting closer to it, requires an effective, global and profound transition of our modes of development and our cultures, which must take place now.

But let's not wait until 2050 to be happy! Current generations can also improve their own living conditions and be happier now as they thrive in this transition.

This transition has already started. Our reason for being is to catalyze it. For the dignity and happiness of humanity who will live tomorrow, but also for those who live today.

We believe that the transition is an opportunity to be happy. That the climate is a challenge that can give meaning to what we do. That getting involved, taking action, in one way or another, makes you happy.

In addition to this, you need to know more about it.

We believe that 2 tons is not an indicator, but a social project, and that if we play down a bit, we can give everyone the freedom to join this project, expressing their singularity and being in control. of his choices.

In addition to this, you need to know more about it.

We believe that everyone's action counts and makes a difference. Whether the transition is possible and depends on us.

We believe that there is room for everyone in the transition, that we should not infantilize people, but trust them.


Our mission is to enable as many people and organizations as possible to become successful players in the transition to a low-carbon world.

In addition to this, you need to know more about it.

For this, we create, thanks to the 2tonnes workshop, immersive, allegorical and educational experiences for individuals in order to:

  • Make them responsible (and not make them feel guilty) and make them aware of their power of action

  • Make them want to act for an objective to which they adhere for its ambition and its values

  • Make them want to act because they thrive in action
