CSI data shows increased carbon emission efficiency since 1990

Switzerland: Global cement producers have reduced CO2 emissions by 17% per tonne of cementitious product since 1990. Participating cement producers reduced their specific net CO2 emissions per tonne of cementitious product to 629kg/t in 2011 from 756kg/t in 2011. The World Business Council for Sustainable Development (WBCSD)'s Cement Sustainability Initiative (CSI) has published the data in its 'Getting the Numbers Right' (GNR) database update for 2011.

"GNR has become established as a valuable source of independently-verified emissions data, which is now used globally by the cement industry to improve energy efficiency and further reduce emissions," said Philippe Fonta, WBCSD managing director. The WBCSD added that the GNR figures provide evidence of the gradual decoupling of emissions and cement output, which demonstrates the significant progress made by the cement industry.

According to the data, the four main drivers for the reduction in emissions have been investment in more efficient kiln technology, increasing use of alternative fuels such as biomass, reduction in clinker content and an 8% decrease in electricity use per tonne of cement since 1990.

The 2011 GNR data comprised 55% of cement production outside of China, with 96% coverage in Europe spanning 967 individual facilities. The 2011 report included data from Thailand, Morocco, Philippines and Egypt for the first time.
