The Environmental & Energy Law Program is tracking the environmental regulatory rollbacks of the Trump administration. Click here for the list of rules we are following.
Why it Matters
The National Highway Traffic Safety Administration (NHTSA) in the Department of Transportation (DOT) has set fuel efficiency standards for cars and light trucks since 1975. In a separate but related process, the Environmental Protection Agency (EPA) has issued greenhouse gas emission standards since in 2010. Transportation is the one of the largest greenhouse gas sources in the US, contributing more than one-quarter of all emissions. Improving the fuel economy of cars saves gas money and lowers emissions; a roll-back of standards increases fuel costs and pollution.
On August 2, 2018 EPA and NHTSA released new proposed standards for greenhouse gas emissions and fuel economy. The agencies propose maintaining the CAFE and CO2 standards applicable in model year 2020 for model years 2021-2026. The agencies propose withdrawing the permission granted to California to set its own greenhouse gas emissions standards, which a dozen other states also use. The Federal Register has published the Trump administration’s proposed fuel economy and greenhouse gas emissions standards for cars and light trucks. The comment period is open through October 23, 2018, and people can comment on a wide range of alternatives, including retaining existing CO2 standards and CAFE standards. NHTSA and EPA will jointly hold three public hearings on the proposed standards: September 24, 2018 in Fresno, California; September 25, 2018 in Dearborn, Michigan; and September 26, 2018 in Pittsburgh, Pennsylvania. The hearings will start at 10 a.m. local time and continue until 5:00 p.m. or until everyone has had a chance to speak.
