Cement Decarbonization Levers

Cement production is one of the hardest industries to decarbonize because most of its CO₂ doesn't come from energy at all — it comes from the chemistry of turning limestone into clinker. This simulator models a cement plant's net emissions per tonne of output as a function of the three real-world levers producers actually pull: substituting clinker with supplementary cementitious materials, switching kiln fuel toward biomass or waste-derived alternatives, and capturing flue-gas CO₂ with CCUS. Adjust each one and watch the flue-gas particle stream — and the live emissions balance — respond in real time, from a conventional ~835 kg CO₂/tonne baseline toward an aggressive low-carbon pathway.
