ZEV reporting requirements
Automakers must submit a ZEV sales report that identifies the necessary delivery and placement data of all vehicles generating ZEV credits. Additional information about this requirement is available in Regulation 20, Part C, Section V.D.
Please submit your ZEV sales report directly to CDPHE by August 31 of the calendar year following the close of the model year. ZEV sales reports from model year 2023, for example, are due by August 31, 2024.
If you choose Option 2 to bank early action credits, then you must also submit sales reports for 2021 (due August 31, 2022) and 2022 (due August 31, 2023) to earn and bank early action credits.
Due to the limitation on how proportional credits can be used to meet ZEV sales requirements for model years 2023 through 2025, Colorado will use its own system for banking ZEV credits.

The second version must have confidential information redacted by the submitter. This second version will be available for release and disclosed publicly.
