Emissions standards for heavy vehicles set to be tightened in the U.S.
By Bradley Osborne - 1st April 2022
USA – The U.S. Environmental Protection Agency (EPA) has proposed the introduction of more stringent restrictions on the emission of nitrogen oxides (NOx) from heavy-duty gasoline and diesel engines. If passed, the new standards could take effect as soon as model year 2027 for some segments.
The EPA is proposing regulations that would reportedly reduce NOx emissions from heavy trucks by as much as 60% by 2045. It estimates that such measures could prevent up to 2,100 premature deaths per year due to respiratory diseases brought on by poor air quality. The EPA will also set new greenhouse gas emissions standards for heavy-duty vehicles by model year 2030.
