2Tonnes

2tonnes Workshop

An immersive three-hour workshop to simulate individual and collective choices through to 2050, understand their effects on emissions and identify the levers available for a low-carbon transition together.

The 2tonnes workshop offers a collective simulation of the choices involved in reducing greenhouse gas emissions through to 2050. Across several rounds, participants make individual and collective decisions and observe their effects through a simulator. Cards and results provide a basis for discussing orders of magnitude, comparing action levers and understanding their interactions. The experience connects everyday practices with wider changes in society. It helps participants reflect on priorities and opportunities for action while keeping the social and ecological dimensions of transition in view. The emphasis is on exploring choices together and understanding how their effects combine.

  • “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.
