Biden Administration Finalizes Greenhouse Gas Target Rule That Is Likely To Draw Challenges

The Federal Highway Administration (FHWA) recently released a prepublication version of its final rule establishing a greenhouse gas (GHG) emissions measure. The final rule establishes a method for measurement of GHG emissions associated with transportation and requires state departments of transportation (State DOTs) and metropolitan planning organizations (MPOs) that have National Highway System (NHS) routes within their jurisdiction to establish targets for reducing GHG emissions from on-road sources and to report on their efforts to meet those targets. The rule will take effect thirty days after the date of its publication in the Federal Register. State DOTs are required to establish targets and report those targets by February 1, 2024. Subsequent targets would be established and reported by no later than October 1, 2026.
