To promote the use of green cement, the German Cement Works Association (VDZ) has introduced a voluntary CO2 label. The aim is to make the CO2 footprint of different cement products comparable. For example, it will indicate the CO2 content of the product on cement bags or shipping bills. „The new VDZ label can be cited in tenders so that the use of CO2-reduced cements becomes standard in construction,“ says Christian Knell, President of the VDZ.
