EMFAC2011
EMFAC2011 is the latest installment of the EMFAC series of models, which is ARB's tool for estimating emissions from on-road vehicles. The model has been updated since EMFAC2007 and is now comprised of three separate modules. Because running the model is more complex now than for EMFAC2007, we recommend users obtain EMFAC2011 output from our new web-based data access tools provided below.
