Environmental 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 three 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. Also included is a county-level summary of the PM2.5 and ozone-related health impacts avoided as a result of a one µg/m3 reduction in annual mean PM2.5 levels or a 1 ppb reduction in average of the summer season daily 8hr maximum ozone levels:
- PM2.5 Benefit Per Ton Estimates - These tables relate changes in directly emitted PM2.5 and PM2.5 precursors from certain classes of sources to an estimate of the monetized PM2.5-related health benefits.
- PM2.5-related impacts of Electrical Generating Units in the Eastern U.S. (Excel file) (34k) - As a means of characterizing the variability in the PM2.5-related health impacts from Electrical Generating Units, EPA is making available a preliminary suite of impact per-ton estimates developed using source apportionment photochemical modeling techniques.
- PM2.5 and ozone impacts per unit change in air quality (zip file) (7.4 MB) - This spreadsheet summarizes the avoided health impacts estimated to occur as a result of a unit change in annual mean PM2.5 levels or summer ozone levels per person at each county in the Continental U.S. This analysis assumes that each person within each county receives the same level of air quality improvement.
