Green Concrete


Concrete is the second most consumed material in the world (second only to water) and accounts for 8% of the global CO2e emissions. The permanent mineralisation of CO2 in concrete (sequestration) is used as a carbon capture utilisation and storage (CCUS) method. Concrete4Change Ltd. (C4C) aims to develop a technology capable of sequestering significant amounts of CO2 in concrete (up to 30%). The sequestration of CO2 results in the strength enhancement of concrete; hence, reducing the amount of cement required to produce equivalent-strength concrete. Both CO2 sequestration and cement reduction can contribute to the reduction of the concrete’s CO2 footprint – up to 60%. This technology has the potential to mitigate 2 billion tonnes of CO2e emissions, the equivalent of 4% of global CO2e emissions.

Key Benefits

Reduction of CO2 emissions of concrete, reduce cement consumption hence price of concrete
