IEA (2009), "Technology Roadmap - Cement", IEA, Paris https://www.iea.org/reports/technology-roadmap-cement
Recognising the urgency of identifying technology to reduce the CO2 intensity of cement production, the IEA has worked together with the World Business Council for Sustainable Development (WBCSD) Cement Sustainability Initiative (CSI) to develop a technology roadmap for cement. This is currently the only industry-specific roadmap; others focus on specific technologies. This joint effort shows willingness to build on progress already made, as well as the industry’s understanding that further progress lies ahead. CO2 emissions from cement production currently represent about 5% of anthropogenic global CO2 emissions. The cement roadmap outlines a possible transition path for the industry to make continued contributions towards a halving of global CO2 emissions by 2050. As part of this contribution, this roadmap estimates that the cement industry could reduce their emissions 18% from current levels by 2050. A reduction of global emissions does not imply a linear reduction by the same percentage in all industries. This roadmap should be understood as a deep analysis of potentials and challenges in one industry.
