|Abstract:||CO2 emissions from fuel combustion represent the majority of anthropogenic GHG emissions. However, comprehensive analysis of emission trends considers other sources of CO2 as well as other gases, knowing that data on gases and sources other than CO2 from fuel combustion are much more uncertain. Country- specific estimates of CO2 from biomass burning and F-gas emissions are particularly difficult to ascertain. To complement work regarding the emissions of CO2 from fuel combustion, the IEA elected to include EDGAR data on other CO2 sources and on five other greenhouse gases; methane (CH4), nitrous oxide (N2O) and the fluorinated gases (or “F-gases”) HFCs, PFCs and SF6, all gases addressed by the Kyoto Protocol. Main changes in this edition are: (a) CO2 emissions from fuel combustion were calculated by the IEA using the default emission factors from the 2006 IPCC guidelines instead of the 1996 Guidelines, thereby increas- ing emissions by about 0.5% to 2%; (b) CO2 emissions from carbon released in fossil fuel use, labelled in the sectoral energy balance as ‘non-energy use’ or ‘chemical feedstock’, are now reported in the Tables under Industrial Processes and Others and taken from the EDGAR4.3.0 dataset (mainly based on the production of specific chemicals, whereas previously estimated by IEA using consumption of specific fuels and default fractions stored by fuel type); (c) CO2 emissions of fugitive nature (such as leakages, transformation losses, flaring) and of non-combustion emissions from industrial processes are also taken from the EDGAR4.3.0 dataset and reported in the Tables under Fugitives and Industrial Processes. The information in Part III (with the exception of CO2 emissions from fuel combustion) has been provided by Jos G.J. Olivier from the PBL Netherlands Environmental Assessment Agency and Greet Janssens- Maenhout from the Joint Research Centre (JRC) of the European Commission, using the EDGAR database (version 4.3.0 and 4.2FT2010) developed jointly by JRC and PBL. Please see Chapter 2 for further details on data sources and methodology.|
