Heavy trucks — including vocational trucks, mostly in our case dumps  — future fuel mileage and emissions are coming under Washington’s control.

Proposed federal standards for greenhouse gas emissions and fuel economy for heavy-duty trucks announced Oct. 25 would reduce CO2 emissions and fuel consumption 20 percent by the 2018 model year.

For vocational vehicles the start year is 2014 with a proposed 10 percent reduction in fuel consumption and CO2 emission to be achieved by 2018. The vocational standards vary by weight class: Light Heavy (Class 3-5); Medium Heavy (Class 6-7); and Heavy Heavy (Class 8).
