In this Climate Solutions Workshop, Director of Programs Ellie Johnston shares the power of the En-ROADS Simulator and the interactive facilitation techniques we have pioneered to accompany the tool to provide interesting and engaging lessons on climate change science and solutions. Developed by Climate Interactive and MIT Sloan, En-ROADS is a system dynamics model carefully grounded in the best available science, calibrated against a wide range of integrated assessment model scenarios, and used by over a million people in more than 160 countries.
