The U.S. Environmental Protection Agency (EPA) announced on Tuesday that new heavy truck makers will have to cut nitrogen oxide emissions by more than 80 percent, the latest move in an effort toward implementing the Biden administration’s “Clean Truck Plan.”

The new standards will go into effect from 2027.
