Trucking industry worried after EPA issues final rule on NOx emissions
The Environmental Protection Agency made good on its promise to issue a final rule on heavy-duty truck tailpipe emissions by the end of the year, but the first take on the rule from engine manufacturers and trucking organizations is that compliance will be difficult.
The agency earlier this year proposed two options for drastically reducing nitrous oxide (NOx) emissions: a two-step process with standards getting progressively tighter in model years (MY) 2027 and 2031, or a one-step standard in...
Trucking braces for new heavy-duty engine emission standards
The Biden administration will soon issue new tailpipe emissions standards for trucks that most truckers — from single owner-operators to owners of large fleets — warn could place heavy cost burdens onto the U.S. economy as a recession already looms.
As proposed by the U.S. Environmental Protection Agency in March, the new nitrous oxide (NOx) emissions standards for heavy-duty truck engines will be either a two- or one-step process.
The two-step process, Option 1, would set a stringency increase...
