The Climate Action Simulation is a highly interactive, role-playing game for groups that can be run online or in-person. It uses the En-ROADS simulation model to engage participants in exploring key technology and policy solutions for addressing global warming. The game is conducted as a simulated emergency climate summit organized by the United Nations that convenes global stakeholders to establish a concrete plan that limits warming to Paris Agreement goals. This game is a fun format for large groups to explore climate change solutions and see what it would really take to address this global challenge.
