EPA DEQ Model Updated to Include Alternative Fuel Emission Factors
The change is a partial victory for alternative fuel advocates but falls short of including the higher in-use emission factors for diesel vehicles that are included in several other government sponsored models such as AFLEET and HDVEC. Using the best and most up-to-date emission factors is important is ensuring that applicants submitting alternative fuel projects for federal or state funding are given full credit for benefits of their deployment of alternative fuel vehicles.
A number of states rely exclusively on the DEQ tool to evaluate DERA or Volkswagen Funding Opportunity. NGVAmerica has successfully argued that states should also allow applications to use the AFLEET or HDVEC tools when submitting project applications. A number of states have been receptive to this argument and now allow the use of these tools. See What’s New on the EPACleanDiesel page.
