2Tonnes
2tonnes Workshop
A serious game that helps participants test pathways to 2050, compare individual and collective choices, and move from diagnosis toward action through a more advanced simulation format.
The 2tonnes Workshop is a serious game that brings together 6 to 15 participants for three hours to take on the climate challenge. Originally developed by François Laugier following feedback from Climate Fresk participants, and later refined in collaboration with Pierre-Alix Lloret, the workshop is now supported by both a nonprofit organization and a social economy company. Over 8 rounds representing 3 to 4 years each, participants make individual and collective decisions to try to move from the average carbon footprint down to 2 tonnes of CO2 equivalent per year by 2050, in line with the Paris Agreement. Using a real-time simulator and paper cards, the workshop quantifies the carbon benefits of each decision and helps participants understand orders of magnitude, prioritize actions, and unlock the transition from awareness to action. It also fits within a broader systems perspective that includes planetary boundaries and Kate Raworth’s Doughnut Theory, helping participants connect climate choices with the wider ecological and social transition. In 2024, more than 9,000 facilitators had been trained and more than 177,000 people had taken part in 2tonnes in over 50 countries.
-
“How can I reduce my carbon footprint by 2030? And after that?”
-
“What is the real impact of my choices on the climate, and how should I prioritize my actions?”
-
“How can we unlock action in the face of the climate emergency?”
These questions are at the heart of the concerns of many citizens, organizations, and decision-makers facing the ecological transition. The 2tonnes Workshop offers a concrete and engaging way to explore them. In 3 hours, participants simulate the evolution of emissions through to 2050, measure the impact of individual and collective decisions, and discover what it takes to reach the 2-tonne target. Beyond carbon, the workshop is an opportunity to reflect on a more fulfilling and fairer society while exploring how meeting the climate challenge can also address other ecological and social issues. That broader perspective is made more explicit through the Doughnut framing used by 2tonnes, which links climate action with social foundations and planetary boundaries. Recognized internationally, 2tonnes is a powerful tool to raise awareness, build commitment, and support action at every level.
- This workshop is developed by its own association. Ecogames helps organize it, include it in public events, and connect venues with trained facilitators.
- Ecogames distributes more than half of registration fees back to the workshops' supporting associations, funding their deployment, evolution, and updates.
