Tracking progress 2020
The direct CO2 intensity of cement production increased 0.5% per year during 2014-18. To get on track with the SDS, a 0.8% 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). Governments can stimulate investment and innovation in these areas through funding RD&D and adopting mandatory CO2 emissions reduction policies.
