C-ROADS – Climate Simulation for Decision Makers

In partnership with the Sustainability Institute and MIT, Ventana Systems has developed “C-ROADS” (formerly called “Pangaea”), a decision-maker-oriented international climate simulator. C-ROADS helps users understand the long term climate impacts of various futures for fossil fuel emissions, other emissions, sequestration, and various uncertainties.C-ROADS simulation output: Regional EmissionsC-ROADS stands for “Climate Rapid Overview and Decision-support Simulator.” As opposed to most climate models, which take days or weeks to run and are designed for scientists, this simulator will be posted in its 3-region form as freeware on the internet, can be used by non-modelers, and runs in less than .1 second on a laptop. The simulator operates at three levels of regional disaggregation — 3, 7, or 14 global negotiating blocs, helping to answer questions such as “what if all countries follow their current commitments?” IE, what if the EU really reduces emissions 80% below 1990 by 2050, the US follows something like the Warner-Lieberman Act, Mexico drops 10% below 2004 by 2014, and China continues decreasing its emissions intensity and so on? In practice negotiations and in strategy conversations, C-ROADS has helped both technical and non-technical people quickly understand the long term implications (CO2 concentration, temperature, sea level rise) of climate agreements while considering per capita, cumulative, future, and current emissions as well as GDP, populations, and emissions intensity. In recent some uses,

  • Schlumberger’s science education program, SEED, created an animated simulation using C-ROADS, andPer Andersson of Ericsson in Sweden used the Schlumberger animated simulation in dozens of presentations in his company.
  • Morgan Stanley’s Office of Sustainability created a video for its employee education program on climate change issues.
  • Bill Moomaw of Tufts University used a slide deck created from the C-ROADS simulator in a presentation to an IPCC committee.
  • MIT’s Center for Collective Intelligence is creating an “argumentation and deliberation” program that will call upon C-ROADS, to help users debate climate solutions.

Potential uses range from private strategic planning sessions to “mock-U.N.” negotiations (at MIT, for European business leaders in Greenland, and for national security strategists in Washington DC with the Center for a New American Security) to posting the simulator globally in multiple languages to help global citizens understand and influence mitigation approaches.

Work on C-ROADS is part of Ventana’s broader efforts on energy, economy and climate policy interactions.
