Federal Regulators Formally Publish Phase 2 GHG Emissions-Reduction Proposal
Federal regulators on July 13 formally published their proposal in the Federal Register that would tighten greenhouse-gas emissions for trucks, improve their fuel economy and regulate trailer efficiency for the first time.
Details of the Phase 2 joint proposed rule were first announced June 19 by the U.S. Environmental Protection Agency and National Highway Traffic Safety Administration.
The proposal would phase in more stringent standards for heavy- and medium-duty trucks from 2021 through 2027. The more than 1,000-page main proposal includes separate standards for engines and vehicles. The trailer regulation would kick in Jan. 1, 2018, and then tighten in 2021 and 2024 before reaching its most stringent level in 2027.
The two agencies will accept comment on the proposal through Sept. 11.
