The U.S. Environmental Protection Agency Office of Transportation and Air Quality (OTAQ) are currently developing a new mobile source emissions factor model called MOVES. This new model will estimate greenhouse gas (GHG) emissions for highway vehicles and will be incorporated into transportation GHG inventory development. Besides other improvements in the methodology, the model will use updated emission factors for nitrous oxide (N2O) and methane (CH4). While MOVES is somewhat behind schedule, data to update N2O and CH4 emission factors are available for this year's inventory. These revised emission factors will be incorporated into the model itself. |
