Abstract: Emissions Modelling: An Analysis of the Average Speed Emission Function with Copert Emission Factors in a Spreadsheet This research delivers distinctive improvement in emissions inventory by rendering the Copert average speed approach more robust. Copert average speed functions are compared with other emission tools with focus on how it is used in TREMOVE. Emission functions and correction algorithms have been utilised to construct the Copert model in Excel. The resulting tool, Copert in Excel, is very robust and efficient and allows for sensitivity analysis to various input parameters.A case application of the tool in Flanders clearly denotes how the robustness of emission factor generation is improved by applying speed distributions rather than a single average speed input. Cumulative gains from applying the research methodology were up to; 9.7% for particulate matter (PM2.5), 7.1% for carbon monoxide, 4.3% for nitrogen oxides and 2.3% for hydrocarbons.
