2018v2 Emissions Modeling Platform

The 2018 Emissions Modeling Platform is based on the 2017 National Emissions Inventory released in the spring of 2020, including updates to specific sectors to represent emissions from 2018.  It was created in support of the 2024 particulate matter National Ambient Air Quality Standards (PM NAAQS). The modeling platform contains base year emissions inventories for 2018, spatial surrogates, and other ancillary files. This platform includes projected emissions for the year 2032.
