Sector-based PM2.5 Benefit Per Ton Estimates
The tables below report the PM2.5 and ozone benefit per ton values calculated using methods consistent with those described in Characterizing the PM2.5-related health benefits of emission reductions for 17 industrial, area and mobile emission sectors across the U.S. (Fann, Baker and Fulcher 2012). In October if 2021 EPA quantified the benefit per-ton of reducing directly emitted PM2.5, PM2.5 precursors and ozone precursors for 21 sectors. The estimates summarized in the table below are valued in 2016 dollars, reflect the use of a 3% discount rate, and are quantified using the Turner et al. (2015) PM2.5 mortality and ozone mortality risk estimates. The 2025 estimates account for population, baseline death rates, and income growth projected to the year 2025. Emissions and air quality modeling predictions for both analytical years are anchored to the year 2016. The methodology is discussed more completely in the Technical Support Document Estimating the Benefit per Ton of Reducing PM2.5 and Ozone Precursors from 21 Sectors, which includes: (1) a BPT for each sector below for the years 2025 and 2030; (2) a benefit per ton estimated using a 3% and 7% discount rate.
