MJB&A has updated it analysis on cost savings associated with stringent GHG and fuel economy standards for medium- and heavy-duty trucks. MJB&A's original report, released in May 2014, was produced for the Environmental Defense Fund and Ceres. The updated analysis models significnatly lower future U.S. diesel prices based on new fuel cost projections by the Energy Information Administration, as well as lower costs for more efficient equipment based on information from the International Council on Clean Transportation. An EDF blog post provides additional information on the update.
A presentation on the updated analysis is available here.
