This white paper describes the U.S. regulatory agencies work on the second phase of heavy-duty vehicle greenhouse gas (GHG) and efficiency standards. Using a new 2010-emissions-compliant engine map and a detailed energy audit to model tractor-trailer technology, the authors find there are diverse technology approaches available, significant energy efficiency potential, existing regulatory procedures and technology potential in the mid-term and long-term that can reduce fuel use.
