The EMission FACtors (EMFAC) model is used to calculate emission
rates from all motor vehicles, such as passenger cars to heavy-duty trucks, operating on highways, freeways and
local roads in California. EMFAC2007 is the most recent version of this model.

REVISION: Both
the EMFAC and OFFROAD Models develop CO2 and CH4 emission estimates; however, they are not currently used as the
basis for ARB's official GHG inventory which is based on fuel usage information The ARB's official GHG inventory
can be found at the link below:
http://www.arb.ca.gov/cc/inventory/inventory.htm
However, ARB is working
towards reconciling the emission estimates from the fuel usage approach and the models.
