The En-ROADS Climate Solutions Simulator is a fast, powerful climate solutions scenario tool for understanding how we can achieve our climate goals through changes in energy, land use, consumption, agriculture, and other policies. The simulator focuses on how changes in global GDP, energy efficiency, technological innovation, and carbon price influence carbon emissions, global temperature, and other factors. It is designed to provide a synthesis of the best available science on climate solutions and put it at the fingertips of groups in policy workshops and roleplaying games. These experiences enable people to explore the long-term climate impacts of global policy and investment decisions.

En-ROADS is being developed by Climate Interactive, Ventana Systems, UML Climate Change Initiative, and MIT Sloan.

This guide provides background on the dynamics of En-ROADS, tips for using the simulator, general descriptions, real-world examples, slider settings, and model structure notes for the different sliders in En-ROADS.

In addition to this User Guide there is:

• A general support knowledge base at support.climateinteractive.org with frequently asked questions and a contact form
• An in-depth online training on using En-ROADS that can be taken at anytime
• An extensive En-ROADS Technical Reference that covers model assumptions and structure, as well as references for data sources.
