Cement technology roadmap set to achieve 24% CO2 reductions

Published by

A new report by the International Energy Agency (IEA) and the Cement Sustainability Initiative (CSI) has stated that a combination of technology and policy solutions could provide a pathway to reduce direct carbon dioxide emissions from the cement industry by 24% below current levels by 2050.

Cement technology roadmap set to achieve 24% CO2 reductions

The technology roadmap, called Low-Carbon Transition in the Cement Industry, provides an update to the global Cement Technology Roadmap produced in 2009. The aim of the technology roadmap is to identify and develop international collaborative efforts and to provide robust evidence for decision making in both industry and policies to keep progressing towards a sustainable cement sector that contributes to the effort of limiting the global temperature increase to 2°C.

The roadmap uses a bottom-up approach to explore a possible transition pathway based on least-cost technology analysis for the cement industry to reduce its direct CO2 emissions in line with the IEA’s 2DS. Reaching this goal would require a combination of technology solutions, supportive policy, public-private collaboration, financing mechanisms, and social acceptance.

Improving energy efficiency and switching to alternative fuels, in combination with reducing the clinker content in cement and deploying emerging and innovative technologies like carbon capture and the use of alternative binding materials are the main carbon-mitigation methods available in cement manufacturing.

Further emissions savings can be achieved by taking into account the overall life cycle of cement and concrete. This can include optimising the use of concrete in construction by maximising design life of buildings and infrastructures, encouraging reuse and recycling, reducing waste and benefiting from concrete’s properties to minimise energy needs for the heating and cooling of buildings.
