Zero-Emission Transport Refrigeration Unit (TRU) Regulation
- As of October 1, 2022, the effective date of the 2022 Amendments, truck TRUs are no longer subject to the in-use performance standards and are required to meet a zero-emission fleet requirement.
- TRU owners are required to turnover at least 15 percent of their truck TRU fleet (defined as truck TRUs operating in California) to zero-emission technology by December 31, 2023, and each year thereafter for seven years.
- Model year 2014 and older truck TRU engines were required to comply with ultra-low emission TRU in-use performance standard on or before December 31, 2021, prior to the October 1, 2022, effective date of the 2022 Amendments. Therefore, model year 2014 and older truck TRU engines that do not meet the ultra-low emission TRU in-use performance standard (have a Level 3 filter or use a qualifying Alternative Technology) can be cited for non-compliance if they operate in California.
