In September 2000 the German Cement Works Association presented the “Environmental Data of the German Cement Industry” for the first time. From 2005 on the data have been published in English as well.
Extent and contents remain largely unchanged.

In 2011 again all clinker producing works in Germany took part in the survey on which these figures are based. As a consequence, a complete documentation of both the results of continuous emission monitoring and of individual measurements of trace elements and organic exhaust gas constituents can be presented for the year 2011.
