2022v1 Emissions Modeling Platform

The 2022 Emissions Modeling Platform is based on the 2020 National Emissions Inventory released in the spring of 2023 with updates to better represent the year 2022.  It is being created as a product of the National Emissions Inventory Collaborative and will support multiple regulatory and non-regulatory applications. The modeling platform contains emissions inventories for 2022, spatial surrogates, temporal profiles, and other ancillary files. Analytic year emissions inventories for the years 2026, 2032, and 2038 for Version 1 of the 2022 platform are currently being developed. Version 2 of the platform is scheduled to be developed in 2025.
