Use of Models and Facility-Level Data in Greenhouse Gas Inventories Use of COPERT 4 for the compilation & sub-mission of road transport GHG inventories L. Ntziachristos ETC/ACC Invited Background Paper to the IPCC Experts Meeting, Sydney, Australia, 9 – 11 August 2010 IPCC Expert Meeting Report 120 TFI
Use of Models and Facility-Level Data in Greenhouse Gas Inventories Background COPERT 4 is a methodology and software that can be used for the compilation of national emission inventories in the framework of UNFCCC and CLRTAP. For UNFCCC submissions, COPERT may assist national experts in the compilation of their inventories by including the appropriate methodology and emission factors to calculate CO 2, N 2O, and CH 4 emissions from road transport. COPERT (software and/or methodology) is used by 18 out of the 27 EU countries for the preparation and submission of national inventories. Support for the official use of COPERT 4 in Europe is provided by the European Environmental Agency through the European Topic Centre on Air and Climate Change while its methodology development is coordinated by the ERMES group and is reviewed by TFEIP. The Laboratory of Applied Thermodynamics and their spin-off company EMISIA SA are responsible for the scientific and technical support of the program. Methodology The methodology of COPERT 4 is described as the Tier 3 method of the EMEP/EEA emission inventory guidebook, which is directly referenced in the IPCC2006GLs. COPERT 4 has also delivered the aggregated CH 4 and N 2O emission factors for European cars included in the 2006 Guidelines. Ultimate CO 2 emissions are estimated in COPERT 4 on the basis of fuel consumption only, assuming that the carbon content of the fuel is fully oxidised into CO 2. In the case of an oxygenated fuel described by the generic chemical formula C xH yO z the ratio of hydrogen to carbon atoms and the ratio of oxygen to carbon atoms are, respectively: r H : C = r O : C = y x z x If the fuel composition is known from ultimate chemical analysis, then the mass fractions of carbon, hydrogen and oxygen atoms in the fuel are c, h, and o correspondingly, where c + h + o = 1. In this case, the ratios of hydrogen to carbon and oxygen to carbon in the fuel are respectively calculated as: h r H : C = 11. 916 c o r O : C = 0. 7507 c With these ratios, the mass of CO 2 emitted by vehicles in category j, combusting fuel m can be calculated as: FC × (3) 16.000r CALC CALC j,m E CO 2 , j,m = 44.011 12.011+ 1.008rH:C,m + O:C,m Where FC CALC is the fuel consumption of those vehicles for the time period considered. Table 1 presents relevant hydrogen to carbon and oxygen to carbon ratios for different fuel types. (1) (2) IPCC Expert Meeting Report 121 TFI
