Cement – Analysis - IEA

In the Net Zero Emissions by 2050 Scenario, the thermal energy intensity of clinker production declines 0.8% per year to a global average of 3.2 GJ/t, and the electricity intensity of cement production falls by 1.9% per year to 84 kWh/t. This excludes additional energy required for emissions reductions technologies such as CCUS.
