Transportation Freedom Act Affects Emissions

A bill introduced in the U.S. Senate this month seeks to repeal heavy-duty emissions standards, eliminate new and existing emissions waivers granted to states, set a national standard for emissions and more.
The “Transportation Freedom Act,” as the legislation is known, was introduced by Sen. Bernie Moreno (R-Ohio) and co-sponsored by Sens. Tim Sheehy (R-Montana), Jim Banks (R-Indiana) and James Justice (R-West Virginia). It includes several provisions related to heavy-duty truck emissions standards, as well as provisions addressing light- and medium-duty vehicles.
Notably, the bill would repeal Phase 3 of the Environmental Protection Agency’s Greenhouse Gas Emissions Standards for Heavy-Duty Vehicles. The Phase 3 GHG rule, finalized last year, ramps up CO2 emissions standards for trucks between model years 2027 and 2032.
