The World Business Council for Sustainable Development's (WBCSD) Cement Sustainability Initiative (CSI), founded and cochaired by Lafarge and Taiheiyo Cement, called the G8 members and the UNFCCC to accelerate the creation of effective sectoral approaches that reduce carbon emissions. The cement sector is adopting a sectoral approach on CO2 emissions, thanks to a CO2 measuring and reporting protocol developed by the CSI in 2002, which is now being used by 80% of the world's cement industry.
“As an industry, we are leading in the adoption of tools that can be used to target climate changes,” says Bruno Lafont, chairman and CEO of Lafarge. “Member companies of the CSI have set voluntary individual CO2 reduction targets which are delivering encouraging results and we have today announced a significant drop in emissions per tonne of cement produced by our members.”
These figures show that the average net specific emissions per tonne (metric ton) of cement of its 18 members have fallen from more than 760 kg CO2/tonne in 1990 to 670 kg in 2007. The reduction equals a CO2 savings of more than 70 million tonnes. “These results are encouraging and show that reducing the CO2 intensity in cement is possible,” says Lafont.
As part of its ongoing efforts to identify what cement manufactures can do to improve sustainability in the industry, the CSI developed the first global cement database, charting CO2 and energy, with independently verified data. Visit www.csiprogress2007.org.
