CO2 emissions from cement production currently represent about 5% of anthropogenic global CO2 emissions. Since 2002, CSI member companies have collectively made significant progress on measuring, reporting and mitigating their CO2 emissions, and
sharing their progress with the rest of the cement industry. This technological roadmap is a logical and complementary next step to promote effective action against climate change. 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 its direct 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.
