Climate Rapid Overview and Decision Support (C-ROADS) Simulator

From Open Energy Information

C-ROADS is a computer simulation that helps understand the long-term climate impacts of emission reduction policy scenarios.

This tool is included in the Development Impacts Assessment (DIA) Toolkit from the LEDS Global Partnership.


C-ROADS translates climate mitigation scenarios and pledge levels into emissions, concentrations, temperature, and per-capita emissions outcomes at the global level. The model quickly runs real-time policy analysis on a computer. C-ROADS allows users to test “what if scenarios” and analyze up to 15 different nations or regions simultaneously.

When to Use This Tool

This tool is most useful for development impacts assessments focused on:
