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 applications. The modeling platform contains emissions inventories for 2022, spatial surrogates, temporal profiles, and other ancillary files. Analytic year emissions inventories for the year 2026 are available. Version 2 of the platform is scheduled to be developed in 2025.
