Decarbonization
Large quantities of CO2 are released in the production of cement and its preliminary product cement clinker. Approximately two thirds of this can be attributed to raw material-induced process emissions from limestone calcination, and roughly one third to the energy-related CO2 emissions from the fuels used.
We, Buzzi and Dyckerhoff, are committed to further reducing CO2 emissions throughout our entire cement and concrete value chain, and have stated that in our roadmap "Our Journey to Net Zero“.
We are reducing energy-related CO2 emissions by optimizing the efficiency of our plants and increasingly using alternative fuels. To reduce raw material-induced process emissions, we are replacing part of the raw material mix with alternative raw materials containing calcium and already calcinated materials.
We base the measures to reduce our CO2 emissions on the 5C approach of the European cement association CEMBUREAU – Clinker, Cement, Concrete, Construction und (Re)Carbonation – towards a climate-neutral industry. The German association Verein Deutscher Zementwerke VDZ also builds on this approach in its jointly developed CO2 roadmap for the German cement industry.
The 5C approach describes our industry's path to completely reducing CO2 emissions by 2045 along the value chain stages clinker, cement, concrete, and building, as well as the recarbonation of CO2 into concrete during and after the use of a building component. We are committed to achieving the necessary objectives and course of action.
