 In past years, statistical fuel consumption data from the National Energy Balances for Germany was used (AGEB, 2019)[(Arbeitsgemeinschaft Energiebilanzen (Hrsg.): Energiebilanz für die Bundesrepublik Deutschland; URL: http://www.ag-energiebilanzen.de/7-1-Energy-Balance-2000-to-2015.html)]. But a comparison with data from German ETS (available as of 2005) exposed several inconsistencies within these statistics. In past years, statistical fuel consumption data from the National Energy Balances for Germany was used (AGEB, 2019)[(Arbeitsgemeinschaft Energiebilanzen (Hrsg.): Energiebilanz für die Bundesrepublik Deutschland; URL: http://www.ag-energiebilanzen.de/7-1-Energy-Balance-2000-to-2015.html)].

 The emission factors for pipeline comporessors have been taken from the research project "Determination and evaluation of emission factors for combustion systems in Germany for the years 1995, 2000 and 2010" (DFIU, 2002)[(Rentz, O.; Karl, U.; Peter, H.: Ermittlung und Evaluierung von Emissionsfaktoren für Feuerungsanlagen in Deutschland für die Jahre 1995, 2000 und 2010; Forschungsbericht 299 43 142 im Auftrag des Umweltbundesamtes; Dezember 2002.)]. A detailed description of the procedure is presented in Chapter: 1.A.1.a - Public Electricity And Heat Production. In 2018 and 2019emission factors were revised by using emission data from large combustion plants (UBA, 2019)[(Kristina Juhrich, Rolf Beckers: "Updating the Emission Factors for Large Combustion Plants": https://www.umweltbundesamt.de/publikationen/updating-emission-factors-large-combustion-plants)]. The emission factors for pipeline comporessors have been taken from the research project "Determination and evaluation of emission factors for combustion systems in Germany for the years 1995, 2000 and 2010" (DFIU, 2002)[(Rentz, O.; Karl, U.; Peter, H.: Ermittlung und Evaluierung von Emissionsfaktoren für Feuerungsanlagen in Deutschland für die Jahre 1995, 2000 und 2010; Forschungsbericht 299 43 142 im Auftrag des Umweltbundesamtes; Dezember 2002.)].

 Compressor stations, in Germany mostely gasturbines are responsible for maintaining a constant pressure in the pipline. Basically they work discontinuously which causes relatively high specific emissions. In order to reflect this point the German law allows exemptions for installations with a low level of utilization. Compressor stations, in Germany mostely gasturbines are responsible for maintaining a constant pressure in the pipline.
