The Long-range Energy Alternatives Planning - Integrated Benefits Calculator (LEAP-IBC) Factsheet

This factsheet describes the key features of the LEAP-IBC tool. The Long-range Energy Alternatives Planning (LEAP) - Integrated Benefits Calculator (IBC) is an integrated planning tool to help governments jointly assess greenhouse gases, short-lived climate pollutants (SLCPs) and other air pollutant emissions; build mitigation scenarios; and understand how emission reductions benefit climate, health and crops.

The Integrated Benefits Calculator (IBC) is a new application of the LEAP system developed by the Stockholm Environment Institute 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.
