Cement – Analysis - IEA

The direct CO2 intensity of cement production increased % per year during 2014 18. To get on track with the SDS, a % annual decline is necessary to 2030. Sharper focus is needed in two key areas: reducing the clinker-to-cement ratio (including through greater uptake of blended cements) and deploying innovative technologies (including CCUS).
