Methods for calculating transport emissions in the Netherlands

31-05-2013 | Publication

This report describes the methodologies, emission factors and relevant activity data used to calculate the emission of environmental pollutants from mobile sources in the Netherlands. The emissions are calculated, annually, by the Task Force on Transportation of the Dutch Pollutant Release and Transfer Register (PRTR). The resulting emission data on greenhouse gases are reported, annually, in National Inventory Reports, and air polluting emissions are reported in Informative Inventory Reports. These reports also provide a brief description of the trends in emissions and the methodologies used for calculating emissions. These methodologies and underlying data are described in more detail in the present report.

The present report describes the methodologies used for calculating the emissions over the 1990–2011 time series, which are reported in the 2013 National Inventory Report and the 2013 Informative Inventory Report. It has been compiled by the Task Force on Transportation of the PRTR, which includes members of Statistics Netherlands, PBL Netherlands Environmental Assessment Agency, the Netherlands Organisation of Applied Scientific Research TNO and the RWS Centre for Transport and Navigation (DVS) of the Dutch Ministry of Infrastructure and the Environment. More general descriptions of the Dutch PRTR and the different task forces can be found on the international pages of the website of the Dutch PRTR (

Role of PBL Netherlands Environmental Assessment Agency in the national emission inventory

Until 2009, PBL Netherlands Environmental Assessment Agency was the coordinating institute for the Dutch emission inventory (emissieregistratie). This role has since been taken over by the National Institute for Public Health and the Environment (RIVM), while PBL continues to be a member of the various task forces of the Dutch PRTR. The PRTR comprises task forces for specific economic sectors, such as transport, industry and agriculture. Task forces both supply and assess emission estimates, guard the quality and robustness of methods, keep pace with new scientific insights and, where necessary, are responsible for implementing new methods. Involvement is important to PBL, in order to remain up to date on emission developments and to use this knowledge in its outlook studies, assessments, evaluations and calculations of policy options.
