This paper presents a review of existing literature on emission
factors, emission data collection
techniques, and
analytic approaches; presents the results of SAIC's analysis of available CO2 and CH4 GHG emission data from chassis dynamometer tests of heavy - duty vehicle exhaust; and provides suggestions for further reducing this uncertainty.
