EPA, DOT Release Phase 2 Gas Emissions Regs for Heavy Duty Trucks
The 1,650-page final rule was created in an effort to further reduce greenhouse gas emissions and fuel-consumption from medium and heavy-duty vehicles and engines. The new rule focuses on four specific standards for each type of heavy-duty vehicle:
- combination tractors
- trailers used in combination with those tractors
- heavy-duty pickup trucks and vans
- vocational vehicles
The rule also outlines separate standards for engines that power combination tractors and vocational trucks, as well as natural gas engines.
