CO2-Reduktion in der Zement- und Kalkindustrie – Wie vermeidet man unvermeidbare Emissionen?

CO2 reduction in the cement and lime industry - How to avoid unavoidable emissions? CO2 emissions of the cement and lime industry are an especially challenging topic for the climate policy debates, because the process emissions from these industries are unavoidable. To reach the goal of climate neutrality, it is necessary to minimize the consumption of cement clinker and other products made from lime stone, as well as to utilize Carbon Capture and Storage (CCS) to capture and permanently store CO2. In highly developed industrial countries with a projected reduction in population, such as Germany, the demand for cement could drop to half of current consumption. Worldwide, however, a constant demand is expected despite ambitious reduction measures. Therefore, implementation of CCS is key to achieving a climate neutral cement and lime industry. Technical questions are largely solved and main barriers to a fast and wide-spread implementation are mainly a lack of regulatory frame work and a low public acceptance of the technology.
