Many canonical integrated assessment models examining the relationship between energy, climate, economics, and public policy represent negative emissions interventions poorly and haphazardly, if these approaches to decarbonization are included at all in such models. This grant supports work by scholars at the Institute for Carbon Removal Law & Policy at American University to improve how negative emissions technologies are represented in two of the most often used integrated assessment models. One of these models, EnROADS, is a highly aggregated economy-climate-energy model. The other, the Global Change Assessment Model (GCAM), is one of the most widely used open source energy and climate models in the field. Grant funds will support two postdoctoral researchers, who will work to develop extensions of these two models to better account for the potential emergence of negative emissions (decarbonization) technologies over the coming decades.
