-The procedure used to determine emission factors for the various glass types involved and the pertinent emissions is described in detail in reports of two research projects (2008: Report-No. 001264, 2021: Texte 45/2021). The emission factors were calculated for the various industry sectors. The factors vary over time in keeping with industry monitoring, not only as steady trends, but falling in most cases. The most recently EF are for different glass types the following:+The procedure used to determine emission factors for the various glass types involved and the pertinent emissions is described in detail in reports of two research projects (2008: Report-No. 001264[(UFoPlan FKZ 206 42 300/02: Teilvorhaben 02: „Providing up-to-date emission data for the glass and mineral fiber industry“ downloading via search “UBA-FB 001264” in (https://doku.uba.de ⇒ OPAC ⇒ use parameter ‘Signatur’)], 2021: Texte 45/2021[(ReFoPlan FKZ – 3719 52 1010: „Revision of emission factors for air pollutants in the cement clinker production and glass manufacturing sectors“ downloading via https://www.umweltbundesamt.de/sites/default/files/medien/5750/publikationen/2021-03-18_texte_45-2021_luftschadstoff_glasindustrie.pdf)]).
