C-Learn is designed for people learning about the impacts of carbon emissions and the level of action required by developed and developing countries to effectively address those impacts. It is the more often used climate simulation with World Climate. C-Learn is accessed through a web-based user interface. The three regions in C-Learn sufficiently represent the differences in global fossil fuel use to make World Climate effective without adding potentially distracting details to the exercise.
C-ROADS operates from a laptop computer and is useful if the exercise venue has no Internet connection. The additional complexity of six regions may be appropriate for some facilitators who wish to pursue more details about the climate simulation itself or about some of the major individual countries/regions—the US, EU, China and India. C-ROADS can be obtained by requesting a download from Climate Interactive. C-ROADS is not available for Mac operating systems directly but will operate in a Windows emulated environment on the Mac. C-ROADS requires Microsoft Excel.
En-ROADS is a global model that focuses on how changes in the energy, economic, and public policy systems could affect greenhouse gas emissions and climate outcomes. It uses C-ROADS for its underlying climate simulation. En-ROADS is currently under development, as is a “World Energy” exercise for use with En-ROADS. Check back for progress and availability.
