U.S. EPA proposing rules to cut emissions from heavy trucks

WASHINGTON, March 7 (Reuters) – The U.S. Environmental Protection Agency (EPA) on Monday said it was proposing new rules to cut smog-forming and greenhouse gas emissions from heavy duty vehicles.

The EPA is proposing to require cuts in nitrogen oxide emissions from heavy trucks of 47% to 60% by 2045. The new standards would begin in the 2027 model year.

The administration also proposes stricter new greenhouse gas emissions standards for some types of heavy vehicles.

The EPA said the rules would dramatically improve air quality and if the more stringent rules were finalized there would be up to 2,100 fewer premature deaths and 3.1 million fewer cases of asthma symptoms and other health issues.

EPA is proposing to tighten greenhouse standards starting in 2027 for 17 of the 33 subcategories like school buses, transit

buses, commercial delivery trucks, and short-haul tractors and is seeking comment on whether it should increase the stringency of standards through 2029.

Separately, the Transportation Department is announcing nearly $1.5 billion in funding for 2022 to help state and local governments purchase U.S.-built electric transit buses and low-emission models. The department is also announcing $2.2 billion in funding to 35 transit agencies across 18 states.
