Our purpose is to understand the relative importance of industry, business unit and time on the profitability of Belgian companies described by 3 and 4-digit NACEBEL codes during this time period. Our results so far

As many as 235 different drive cycles, recorded from people participating in a survey, were imported in an emission simulation tool called Vehicle Transient Emissions Simulation Software (VeTESS). Emissions and fuel consumption were calculated with VeTESS using two different gear change assumptions (normal and aggressive). This paper reports on the differences in vehicle exhaust emissions between trips made with those two different settings.
