New document: EPA proposes stricter emissions standards for heavy-duty vehicles
The Environmental Protection Agency is proposing stricter standards to reduce greenhouse gases and nitrogen oxide (NOx) emissions from model year (MY) 2027 and later heavy-duty vehicles and engines, and is seeking input on whether to issue even stricter rules in the future.
If finalized, the EPA estimates that the standards could cut truck NOx emissions by up to 60 percent in 2045, leading to as many as 2,100 fewer premature deaths, 6,700 fewer hospital admissions and emergency department visits, 78,000 fewer lost days of work, 18,000 fewer cases of asthma onset in children, and 1.1 fewer lost school days for children.
