Cement Technology Roadmap

The cement industry has already made significant progress in reducing CO2 emissions through the use of alternative fuels, improved energy efficiency and clinker substitution. However, these technologies must be more broadly applied to realize their full potential.

The roadmap provides a vision for cement industry emissions reductions up to 2050. It identifies the requirement for increased R&D commitment and investment, particularly in carbon capture and storage technologies, and the need for a clear policy framework.

Cement is a key material needed to build societies' infrastructure. The report acknowledges that, although cement production accounts for around 5% of global man-made CO2 emissions, there is no viable substitute; and reduction in demand is not a realistic option in view of the world's continued population growth and increasing rate of urbanization. The report states that; given the right policy frameworks at global, national and local levels, the cement industry could reduce its emissions by 18% by 2050; compared with 2005. However, carbon capture and storage will need to be implemented, if this target is to be met.
