EPA Unveils New Emissions Standards Proposal

The Environmental Protection Agency (EPA) has proposed stricter standards for vehicle emissions, including ones for heavy-duty vehicles. 

The proposed rules are the third phase of the agency’s Clean Trucks Plan, according to an April 12 release, which takes effect with model year 2027. 

Besides adding to the existing plan, the EPA also proposed another set of CO2 standards for heavy-duty vehicles that would begin in model year 2028, “with progressively lower standards each model year through 2032.” 

The full 717-page document can be viewed online. 

New proposed standards are also on the way for light- and medium-duty vehicles, which are set to take effect for model year 2027 vehicles. 

An estimated 10 billion tons of CO2 would be eliminated by 2055 due to these standards, read the release. 

In a statement, EPA Administrator Michael S. Regan described the proposal as “the most ambitious pollution standards ever for cars and trucks.” 

EPA will hold a virtual public hearing for the proposal on May 2 and 3; those who wish to register must email EPA-HD-hearings@epa.gov.
