+ | In Germany, soda ash is produced in three production facilities, all of which use the Solvay process. The production data is thus confidential. | ||
- | In former years, facilities with higher ammonia emissions existed in the New German Länder. However, after 1992, emissions of NH,,3,, occur at a lower level. | ||

+ | The Federal Statistical Office has long time series for this area. Due to the presence of a nearly inexplicable trend in the data of the Federal Statistical Office for the period since 2015, the relevant producers were contacted, and in 2021 cooperation agreements were signed with both producers (for all three production sites). The German Environment Agency (UBA), which consolidates the relevant data, has decided that as of 2013 the pertinent time series is to be filled with the producers’ data (this overlaps with a comparison carried out for the period 2013 through 2021). | ||
+ | Since Germany has only two producers, the production-quantity data from the two sources must be kept confidential. | ||
