The Climate Action Simulation and the World Climate Simulation are both group roleplaying games designed to help participants learn about climate change in an interactive way. 

The World Climate Simulation is a roleplaying exercise of the United Nations climate change negotiations. Through the simulation, participants play the role of country/regional delegates or additional conference attendees such as fossil fuel lobbyists or climate activists. They get to explore the necessary speed and level of action that nations must take to address global climate change. At the heart of the experience is the use of our interactive simulation model C-ROADS, which rapidly analyzes the results of the game play and provides feedback. 

The Climate Action Simulation is conducted as a simulated emergency climate summit organized by the United Nations, convening global stakeholders to establish a concrete plan that limits warming to Paris Agreement goals. Participants act as representatives from these stakeholder groups, such as Conventional Energy or Industry and Commerce. The simulation uses the En-ROADS simulation model to engage a wide range of participants in exploring key technology and policy solutions for addressing global warming.

Length of time to play

1-3 hours. Breakdown of different timelines available here

1.5 hours or more. 3 hours is suggested. Some facilitators break the game into 2 sessions held on different days. 

Facilitator experience required

Fairly limited. One-hour training webinar plus additional preparation and familiarizing yourself with the C-ROADS simulator.

More experience required. Familiarity with the En-ROADS simulator is strongly encouraged. Full training is the free Mastering En-ROADS course at, about 20 hours. If you’re not experienced with En-ROADS, we recommend enlisting the help of an experienced facilitator such as our 

En-ROADS Climate Ambassadors
