The Cement Industry can Achieve Greener Concrete and Curb Emissions Through Carbon Capture and Other Innovations Despite the Challenges

Cement production is a major source of global CO2 emissions, accounting for roughly 8%. A significant portion, up to 70%, stems from the chemical process of calcining calcium carbonate (CaCO3) into lime (CaO) to produce clinker, the primary component of cement. Fossil fuels used in blending, crushing, heating, and grinding clinker also contribute to emissions. While renewable energy is growing, decarbonizing the cement industry poses a considerable challenge. Achieving net zero in this sector, balancing emissions with removal or offsetting, is crucial for limiting global warming to 1.5°C and mitigating severe climate change impacts (Bhatia et al. 2024). This paper ultimately emphasizes the scopes and opportunities of cement industry in shaping a sustainable one. Net zero means balancing the amount of greenhouse gases released with the same amount stored or offset so that the temperature has no effect at all & we need to maintain the same during cement manufacturing.
