Elemental carbon emission factors of vehicles for dutch air-quality assessments
Since a number of years, indicative elemental carbon (EC) emission factors have been circulating in the Netherlands. These numbers had no official status, but grew from a collection of sources. Some important numbers in this collection were questionable, based on outdated test results, or different vehicle technology categories not applicable to new vehicle technologies. Most important GDI’s (gasoline direct injection) EC emissions test results were missing. From the Pollutant Release and Transfer Register (PRTR) there is an interest in the EC emission factors, since EC emissions are used as an estimate to report BC emissions to the Convention of Long-Range Transboundary Air Pollution (CLRTAP). The PRTR have requested this study, to make the results generally available. The Ministry of Infrastructure and the Environment provided additional sponsoring for the emission tests on GDI vehicles. In the process of giving EC emission factors a more official status in the Netherlands, additional tests and analyses were carried out, and this report summarizes aspects related to EC emissions and emission factors.
