Road freight transport is growing with the rapid growth of economic activities resulting in an increase of GHG emission and carbon-based fuels consumption. The sector has been responsible for 35% of the world’s transport energy use and diesel vehicles are the major fuel consumer in Asia [1]. Work towards more sustainable freight transportation should begin with a quantification of Vehicle Emissions (VE) and Fuel Consumption (FC) from the sector. Existing research on the Sri Lankan freight transport sector indicates a research gap in quantifying VE and FC at national level. The absence of a proper methodology to calculate VE and FC due to issues in calculation of diesel vehicle emissions has created this research gap. Based on a recently developed diesel emission calculation equation and previously developed petrol emission calculation method, this study attempts to achieve the following research aims: A. Development of a methodology to estimate VE and FC by road freight transport sector in Sri Lanka. B. Estimation of VE and FC of road freight transport sector in Sri Lanka
