About the Institute:
"A non-profit organization founded in 1996 by the late Donella (Dana) Meadows, the Sustainability Institute applies systems thinking, system dynamics modeling, and organizational learning to economic, environmental and social challenges."
About the climate tools:
"Our primary simulation — the one underneath most of our current work — is the Climate Rapid Overview and Decision-support Simulator (C-ROADS). The online, 3-region version of C-ROADS is called C-Learn and is available here online. And we also have a dynamic, Climate Momentum Simulation, based on multiple runs of our C-ROADS model. We have two much simpler animated simulations completed and available online — the Climate Bathtub Animation and MIT’s Greenhouse Gas Emissions Simulator."
