Clinker, an intermediary used as a binder in cement, is a core component of cement products, but its production process is highly emissive. Lower-carbon clinker uses CCUS technology to capture and manage these carbon emissions before they are released. 7 There is not yet an accepted industry-wide threshold for CO 2 content in green cement.

Cement production is an energy-intensive process consuming thermal energy of the order of 3.3 GJ/tonne of clinker produced. Electrical energy consumption is about 90 – 120 kWh/tonne of cement (Giddings, et al, 2000; European Commission [EC] 2001). Historically, the primary fuel used in cement industry is coal.
