Cement

Reducing CO2 emissions while producing enough cement to meet demand is a global challenge, especially since demand growth is expected to resume.

Direct emissions intensity of cement production in the Net Zero Scenario, 2015-2030

Cement emissions continue to rise, more investment in new technologies is needed

The direct CO2 intensity of cement production increased about 1.5% per year during 2015-2021. In contrast, 3% annual declines to 2030 are necessary to get on track with the Net Zero Emissions by 2050 Scenario. 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, such as carbon capture and storage and clinkers made from alternative raw materials. Governments can stimulate investment and innovation in these areas by funding R&D and demonstration, creating demand for near zero emission cement and adopting mandatory CO2 emission reduction policies.
Our work

The IETS TCP focuses on energy use in a broad range of industry sectors with significant potential for emissions and cost savings. The IETS TCP work programme ranges from aspects relating to development of processes and energy technologies, to overall system analysis and energy efficiency in industry sectors.
