This week is a big week for environment policy. On Monday, the President's Climate Action Plan celebrated its second birthday. That plan outlines a broad set of regulatory and diplomatic action to cut carbon emissions broadly from small passenger cars to large power plants. On Friday, the Administration could check off another box in their strategy as the U.S. Department of Transportation and the EPA issued the 1,600 page "Phase 2" proposed rule to advance fuel economy and reduce greenhouse gas emissions for medium and heavy-duty vehicles that was released last Friday afternoon. Those proposed rules kick-in beginning in model year 2021 and are anticipated to reduce carbon emissions by about 1 billion metric tons by 2027.
While diesel comes with a slightly higher price tag, this study confirms that diesel buyers will definitely get more for their money.
It takes over 60 new heavy-duty trucks to generate the same emissions as a single truck manufactured in 1988. In fact, emissions sensing technology has almost reached its current ability to detect criteria pollutants from the tailpipe of a new truck. Truck and engine manufacturers are now bringing to market further innovations that build on the emission reduction success by reducing fuel use.
