Truck limits.

The U.S. Environmental Protection Agency imposes technology neutral, greenhouse gas limits on heavy duty trucks, shuttle buses, waste haulers and school buses for model years 2027 through 2032.

Manufacturers will be able to choose the emissions-control technology, be it battery electric, hydrogen, hybrid or advanced internal combustion engines, to meet the new standards.
