The Integrated Benefits Calculator (IBC) is a new application of the LEAP system developed by SEI in collaboration with US EPA and Daven Henze at the University of Colorado and with the support of the Climate and Clean Air Coalition (CCAC). LEAP-IBC combines emissions scenarios from LEAP with output from a global atmospheric chemistry transport model and with various exposure-response functions. It then produces national-scale estimates of avoided premature deaths and crop losses. LEAP-IBC also estimates the climate benefits of addressing short-lived climate pollutants (SLCPs), adopting air pollution reduction strategies and implementing greenhouse gas mitigation.
