Abstract

This paper quantifies the effect of a number of input parameters on the emission levels of road transport emissions calculated by means of a bottom-up methodology. The input parameters considered cover small diesel cars, calculation of additional fuel consumption due to the use of mobile air conditioning in passenger cars and light commercial vehicles, fine-tuning of trip lengths and definition of road types for Belgium in 2010. The effect is significant for CO2, and even more pronounced for other pollutants such as NOx, PM2.5, and VOCs.
