Adopting material efficiency strategies to optimise the use of cement can help reduce demand along the entire construction value chain, helping to cut CO2 emissions from cement production. Therefore, demand in 2030 in the Net Zero Emissions by 2050 Scenario is 6% lower than in a baseline scenario in which no steps are taken to reduce demand.
