Air Pollutant Emissions Inventory of Large-Scale Production of Selected Biofuels Feedstocks in 2022 supporting data

Data provided are numeric results used to plot the maps/figures presented in the paper ?Air Pollutant Emissions Inventory of Large-Scale Production of Selected Biofuels Feedstocks in 2022? ([DOI: 10.1002/bbb.1620](http://onlinelibrary.wiley.com/doi/10.1002/bbb.1620/full)).

Data for Figure 4a: List of counties with _R_ exceeding the thresholds with reference to non-attainment areas for 1997 or 2008 8-hour ozone National Ambient Air Quality Standards.

Data for Figure 4b: List of counties with _R_ exceeding the thresholds with reference to non-attainment areas for 1997 or 2006 PM2.5 National Ambient Air Quality Standards as well as 2012 PM2.5 National Ambient Air Quality Standard.

Data for Figure S9 reflects county-level feedstock biomass feedstock production (dry metric tons per square kilometer of county area) for the feedstock examined in our study in support of U.S. biofuel production to meet the updated Renewable Fuel Standard of the Energy Independence and Security Act of 2007 by 2022. Data represents the results for the specific scenario analyzed in the paper.

Data for Figures S10 ? S15 reflects county-level air emissions of nitrogen oxides (NOX), ammonia (NH3), carbon monoxide (CO), sulfur oxide (SOX), particulate matter smaller than 2.5?m and smaller than 10?m (PM2.5 and PM10) and volatile organic compounds (VOC) (kg of pollutant per square kilometer of county area) from the production of selected cellulosic biomass feedstock examined. Data represents the results for the specific scenario analyzed in the paper.
