Overview
In August 2021, the Colorado Air Quality Control Commission adopted modifications to Regulation 20, which established the Zero Emission Vehicles (ZEV) program. The changes took effect in January 2022 for model year 2023 and later. In October 2023, the commission adopted new ZEV requirements according to Regulation 20 for the model years 2027-2032, which took effect in December 2023.
Learn more about Regulation 20.
For model years 2023 through 2025, automakers must make a minimum percentage of ZEVs available for sale as part of their light-duty vehicle offerings in Colorado. Starting with model year 2027, automakers must make a minimum percentage of ZEVs available for sale as part of their light-duty vehicle offerings in Colorado. These requirements for manufacturers will help advance electric vehicle sales in Colorado and help the state meet its Greenhouse Gas reduction goals.
