-Emission factors used are default values from the EMEP/EEA air pollutant emission inventory guidebook 2016 [(EMEP/EEA air pollutant emission inventory guidebook 2016, Copenhagen, 2016)] as well as new national data for POPs from the research project "POP- und Hg-Emissionen aus abfallwirtschaftlichen Anlagen" - Teilvorhaben zum Globalvorhaben „Überprüfung des Standes der Technik der Emissionen prioritärer Schadstoffe für einzelne Industriebranchen (Kleinfeuerungsanlagen und abfallwirtschaftliche Anlagen)“ [(Stöcklein; Gass; Suritsch: "POP- und Hg-Emissionen aus abfallwirtschaftlichen Anlagen", Teilvorhaben zum Globalvorhaben „Überprüfung des Standes der Technik der Emissionen prioritärer Schadstoffe für einzelne Industriebranchen (Kleinfeuerungsanlagen und abfallwirtschaftliche Anlagen)“; URL: https://www.umweltbundesamt.de/sites/default/files/medien/378/publikationen/texte_38_2016_pop-und_hg-emissionen_aus_abfallwirtschaftlichen_anlagen.pdf; UBA-Texte 38/2016; im Auftrag des Umweltbundesamtes, April 2016)] .+Emission factors used are default values from the EMEP/EEA air pollutant emission inventory guidebook 2023 as well as national data for POPs from the research project "POP- und Hg-Emissionen aus abfallwirtschaftlichen Anlagen" - Teilvorhaben zum Globalvorhaben „Überprüfung des Standes der Technik der Emissionen prioritärer Schadstoffe für einzelne Industriebranchen (Kleinfeuerungsanlagen und abfallwirtschaftliche Anlagen)“ [(STOECKLEIN2016)] .
  
-In 2018 the TERT noted that the German Hg EF is 100 times smaller than the default value proposed in the 2016 EMEP/EEA Guidebook and the Cd and Pb EF are 1000 times smaller than the default values proposed in the 2016 EMEP/EEA Guidebook. However, the EF for Pb and Cd are based on national expert judgement: assumption that a) the emissions behave similarly to dust and b) the dust limit value of the air pollution control specification (27th BImSchV) is complied with (to be confirmed on the basis of the new measurement data from 5 crematoria with different exhaust gas cleaning systems). The Hg EF was calculated on the basis of the German report on “OSPAR Recommendation 2003/4 on controlling the dispersal of mercury from crematoria", but is under evaluation.+In 2018, the TERT noted that the German emission factor for Hg is 100 times smaller than the default value proposed in the 2016 EMEP/EEA Guidebook and the emission factors for Cd and Pb being 1,000 times smaller than the proposed default values. The EF set has now been updated.
  
-After the finalization of a research Project [(FKZ 3716 53 3021 „Umweltrelevanz und Stand der Technik bei Einäscherungsanlagen“ (Environmental relevance and state of the art for cremation plants); URL: https://www.umweltbundesamt.de/publikationen/umweltrelevanz-stand-technik-einaescherungsanlagen)] the Hg EF is revised. As part of the project, emission measurements were carried out at six cremation routes. According to OSPAR reporting 2010/2014, approx. 90% of the plants have effective Hg mitigation technology, whereas approx. 10% are not equipped with effective Hg mitigation technology. This ratio is roughly reflected in the 2020 project report, too. +In contrast, the country-specific emission factor for Hg was calculated on the basis of the German report on “OSPAR Recommendation 2003/4 on controlling the dispersal of mercury from crematoria" - and was revised after the finalization of the research project „Umweltrelevanz und Stand der Technik bei Einäscherungsanlagen“ (Environmental relevance and state of the art for cremation plants) [(SCHETTERBITTIG2020)].

-This results in the following weighted mean value: +Since the cremation duration is approximately one hour, the mean value per hour corresponds to the Hg load per cremation and is used accordingly for inventory calculation.
