+ | In Germany, soda ash is produced in three production facilities, all of which use the Solvay process. The production data is thus confidential. | ||

+ | ===== Method ===== | ||
+ | |||
+ | === Activity data === | ||
+ | |||
+ | The Federal Statistical Office determines the total amounts of soda ash produced in Germany, but only in a way that respects confidentiality. | ||

+ | === Discussion of emission trends === | ||
+ | |||
+ | The steep reduction—especially for NH< | ||
+ | |||
+ | All trends in emissions correspond to trends of emission factors. No rising trends are to identify. | ||

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

+ | AD improvements are planned by using production figures of both german producers. |
