On April 12, 2023, EPA announced a proposal for more stringent standards to reduce greenhouse gas emissions from HD vehicles beginning in model year (MY) 2027. The new standards would be applicable to HD vocational vehicles (such as delivery trucks, refuse haulers, public utility trucks, transit, shuttle, school buses, etc.) and tractors (such as day cabs and sleeper cabs on tractor-trailer trucks). Specifically, EPA proposed stronger CO2 standards for MY 2027 HD vehicles that go beyond the current standards that apply under the HD Phase 2 Greenhouse Gas program. EPA also proposed an additional set of CO2 standards for HD vehicles that would begin to apply in MY 2028, with progressively more stringent standards each model year through 2032. This proposed Phase 3” greenhouse gas program maintains the flexible structure created in EPA’s Phase 2 greenhouse gas program, which is designed to reflect the diverse nature of the heavy-duty industry. EPA has conducted outreach with a wide range of interested stakeholders to gather input which we have considered in developing this proposal, and we will continue to engage with the public and all interested stakeholders as part of our regulatory development process.
