+ | \\ | ||
+ | In Germany, soda ash is produced in three production facilities, all of which use the Solvay process. | ||
+ | |||
+ | |||
+ | ===== Methodology ===== | ||
+ | |||
+ | === Activity data === | ||
+ | |||
+ | The Federal Statistical Office determines the total amounts of soda ash produced in Germany, but only regarding confidentiality. | ||
+ | |||
+ | === Emission factor === | ||
+ | |||
+ | Emission factors (for TSP and NH,,3,,) are confidential regarding activity data restrictions. | ||
+ | |||
+ | === Discussion of emission Trends === | ||
+ | |||
+ | > The steep reduction especially for NH,,3,, at the beginning of the 1990s was due to closures in the eastern German industrial sector. For year 1990 for eastern Germany is in case of TSP pointed out the summary figure for the Chemical Industry as a whole. However, after 1992, emissions of NH3 occur at a lower level. | ||
+ | |||
+ | All trends in emissions correspond to trends of emission factors in table above. No rising trends are to identify. | ||

+ | === Recalculations === | ||
+ | |||
+ | With EF and AD remaining unrevised, recalculations were not necessary. | ||
