The cement industry is responsible for about seven per cent of global greenhouse gas emissions. To encourage the decarbonisation of this industry, policymakers and the industry must find ways to incentivise reductions. A study from the Heriot-Watt University and the Institute for Advanced Sustainability Studies (IASS) gives us a first look at how CO2 mineralisation can reduce emissions from cement production by up to 33 per cent at no additional cost – under the right conditions.
