World Climate Simulation

The World Climate Simulation, from Climate Interactive, the MIT Sloan Sustainability Initiative, and U-Mass Lowell’s Climate Change Initiative, is an in-person role-playing exercise of the UN climate change negotiations. Through the simulation, participants 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 computer model C-ROADS, which is used to rapidly analyze the results of the game play. All the materials and tools for the game are available for free in multiple languages.

Tens of thousands of people around the world have participated in World Climate since its debut. Audiences have included Nobel Prize winning scientists, a former U.S. Secretary of State, (actual) UN climate negotiators, university presidents, European Union policymakers, oil executives, and countless students of all ages.

World Climate works best for groups of 8-50 people (although it has been adapted for as many as 500). A facilitator plays the role of a UN leader, while each participant plays the role of a delegate representing a specific nation, negotiating bloc, or, in some cases, an interest group. Everyone then works together to reach a global agreement that successfully keeps climate change well below 2˚C.

Simulation events vary in length, but most run 2-3 hours. Condensed versions have been run in as short as 45 minutes. During the event participants face the climate science, engage in the drama and tensions of global politics, test their ambitions against a climate-modeling tool used by actual climate negotiators, and then reflect on how the experience challenges their assumptions about climate action.
