Benefits Mapping and Analysis Program (BenMAP)

Reduced-Form Tools for Calculating PM2.5 Benefits

In situations in which the data needed to specify the BenMAP model is unavailable, reduced-form benefits tools can be used to quantify the expected health impacts of emission or air quality changes. Here we provide four reduced-form tools that enable users to relate changes in the emissions from certain classes of sources of direct or precursor emissions of PM2.5 to monetized health benefits.  We also provide a report comparing the changes in benefits, as well as concentrations where available, from several reduced-form tools as compared to those from full-form photochemcial modeling and BenMAP processing in five specific emissions scenario examples.
