 The category describes emissions from leakage in the industrial sector and in the residential and institutional/commercial sectors. The activity data is based on results of the German Association of Energy and Water Industries (BDEW) [(BDEW2016)] and of own surveys. The BDEW gas statistics appear with a time lag of up to three years. Data of the Working Group on Energy Balances (AGEB) [(AGEB2019a)] is used to bridge the resulting gap. The category describes emissions from leakage in the industrial sector and in the residential and institutional/commercial sectors.

 The emission factors are country-specific, and they were determined via the research project "Methane emissions via gas use in Germany from 1990 to 1997, with an outlook for 2010" ( Methanemissionen durch den Einsatz von Gas in Deutschland von 1990 bis 1997 mit einem Ausblick auf 2010) Fraunhofer ISI (2000) [(REICHERTSCHOEN2020)]. Pursuant to Arbeitsblatt [Worksheet] G 600(Technische Regel fuer Gasinstallationen [(DVGW2018)] of the German Technical and Scientific Association for Gas and Water (DVGW), a leakage rate of 0-1 l CH4/h has no affect on an installation's functionality. When a leak test shows that an installation is leaking a rate higher than that figure, the installation has to be repaired within the short term. National experts thus consider a value of 2 m³ CH4/year to be suitable. To receive appropriate NMVOC emission factors the gas composition was considered.  The emission factors are country-specific, and they were determined via the research project "Methane emissions via gas use in Germany from 1990 to 1997, with an outlook for 2010" ( Methanemissionen durch den Einsatz von Gas in Deutschland von 1990 bis 1997 mit einem Ausblick auf 2010) Fraunhofer ISI (2000) [(REICHERTSCHOEN2020)].
