AEA road transport emissions and PEFA robustness

forthcoming

The project consists of 2 work packages. The first work package deals with the production of road transport tables for the air emission accounts (AEA). Up until now, the separate tables for the road transport tables in the AEA have not been calculated for Belgium. The current methodology to calculate and integrate road transport emissions of CO2, NOx, NMVOC, PM10 and PM2.5 into the AEA will be finetuned, so as to be able to fill the entire tables. The road transport emissions will be allocated to industries, households and non-residents, and for the emissions by residents the part emitted abroad will be reported separately as part of the bridging items. For carbon dioxide emissions a bridge has to be made to CRF 1A3b, as reported in the UNFCCC greenhouse gas emissions inventory. This implies that carbon dioxide emissions from biomass used for transport purposes are not included. For the other emissions a bridge has to be made to NFR 1A3b, as reported in the CLRTAP emissions inventory. The second work package aims at establishing a stamp of high quality on the Belgian Physical Energy Flow Accounts (PEFA) and guaranteeing that the results are comparable to the PEFA constructed by other countries on the basis of the Eurostat PEFA Builder. Currently, Belgium is using a method that makes use of detailed regional data. This implies that we cannot use the Eurostat PEFA Builder to generate the Belgian PEFA, because the PEFA Builder operates on the basis of national data provided to the International Energy Agency. These two sources of energy data are known not to be free of conflict. With a view of improving the quality of the Belgian PEFA, Belgium wants to assess to what extent the results between the 2 methods differ, and whether it is possible to tweak the PEFA Builder parameters in a fashion that reduces this difference. The comparison between the results of the two methodologies is to serve as a robustness test for the Belgian PEFA methodology.
