There are major challenges which the cement industry in Germany and the entire cement and concrete value chain is facing in their quest for climate neutrality. In recent months, VDZ has therefore drawn up a CO_2 roadmap in cooperation with its member companies, which describes possible scenarios and framework conditions on the way to climate neutrality. Since 1990 German cement manufacturers have managed to reduce CO_2 emissions by 20-25% in both specific and absolute terms. Alongside improvements in the area of thermal efficiency, two factors in particular have been crucial to achieving this success: Firstly, a reduction in the clinker content in cement, and secondly, the increased use of alternative fuels containing bio-mass as a substitute for the majority of fossil energy sources.
