 Germany's glass industry produces a wide range of different glass types that differ in their chemical composition. Germany's glass sector comprises the following sub-sectors: container glass, flat glass, domestic glass, special glass and mineral fibres (glass and stone wool). The largest production quantities are found in the sectors of container glass and flat glass. Further processing and treatment of glass and glass objects are not considered. Germany's glass industry produces a wide range of different glass types that differ in their chemical composition.

-The procedure used to determine emission factors for the various glass types involved and the pertinent emissions is described in detail in reports of research projects (Report-No. 001264, search "UBA-FB 001264" in ([[https://doku.uba.de]] => OPAC => Signatur). The emission factors were calculated for the various industry sectors. The factors vary annually in keeping with industry monitoring, not only as steady trends, but as time ranges. Ranges below are given as averages over all glass types for main pollutants, but as averages over time for heavy metals:+The procedure used to determine emission factors for the various glass types involved and the pertinent emissions is described in detail in reports of 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’)].

-Trends in emissions correspond to trends of emission factors and of activity data. The resulting trends are not constant, but a complex result of different EF for various glass types. So emissions of SO₂ could rising due to increased production Level of a relevant product.+Trends in emissions correspond to trends of emission factors and of production development. The resulting trends are not constant, as a result of different EF for various glass types. So emissions of SO₂ couldn't decrease due to increased production Level of a relevant product.
