+ | ===== Methodology ===== | ||
+ | |||
+ | The emissions are calculated via a higher Tier method resembling a Tier 2 method, as the activity rates are tied to specific emission factors for different glass types. | ||
+ | |||
+ | ==== Activity data ==== | ||
+ | |||
+ | The production figures are taken from the regularly appearing annual reports of the [[https:// | ||
+ | |||
+ | ==== Emission factors ==== | ||
+ | |||
+ | 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 " | ||

+ | ===== Trends in emissions ===== | ||
+ | |||
+ | 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. | ||

+ | ===== Recalculations ===== | ||
+ | |||
+ | Recalculations were necessary due to updated activity data for the last reported year. | ||
+ | |||
+ | <WRAP center round info 60%> | ||
+ | For pollutant-specific information on recalculated emission estimates for Base Year and 2018, please see the pollutant specific recalculation tables following [[general: | ||

+ | =====Planned improvements ===== | ||
+ | |||
+ | For purposes of updating the EF project has started in 2019, results are planned in 2020 [(ReFoPlan FKZ – 3719 52 1010: „Überarbeitung der Emissionsfaktoren für Luftschadstoffe in den Branchen Zementklinkerproduktion und Glasherstellung“)]. | ||
