The rule will ‘devastate’ the U.S. supply chain and raise costs for consumers, a plaintiff said.

The American Petroleum Institute (API) filed a lawsuit on June 18 against the Environmental Protection Agency (EPA) over the agency’s new rules that tighten emissions standards for heavy-duty vehicles.

In March, the EPA finalized new federal greenhouse gas emissions standards for heavy-duty vehicles, such as freight trucks and buses, with the regulations applicable to model years 2027 through 2032.
