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.
The vision for such reductions is ambitious, yet the changes required must be practical, realistic and achievable. This roadmap is a first step. It is only attainable with a supportive policy framework, and appropriate financial resources invested over the long term. The roadmap outlines these policies, estimates financial requirements, and describes technical changes, along with recommendations to support research and development (R&D) and future investment decision-making.
Four distinct ”reduction levers” are available to the cement sector to reduce CO2 emissions:
Cement is a key material for building society’s infrastructure. Demand reduction and/or substitution are not realistic options given growth in developing countries, increasing urbanisation and climate change adaptation needs.
