Global cement emissions standards

Some of the earliest cement plant emission regulations were for dust. The German Cement Association (VDZ) set up a dust committee as early as the 1930s. As well as being the first emission type that was targeted by those outside the industry, cement companies in developing markets often target dust as their first pollutant to remove from the gas stream.
