Welcome to the one-stop shop for NEI-based data, organized by Inventory Year.

Some inventory years do not include all of our data products. For example, the full National Emissions Inventory (NEI), which covers all data categories (point, nonpoint, onroad, and nonroad)  is currently done on a triennial basis, and the latest release is 2020. However, for modeling purposes, a 2022 platform was created, for which some of the latest 2022 data was incorporated.
