The Cement Sustainability Initiative (CSI) has released data for the 2011 Getting the Numbers Right (GNR) programme. The results reveal that specific net CO2 emissions/t of cementitious material fell by 17% from 756 kg/t in 1990 to 629 kg/t in 2011. Compared to 2010, real improvements in efficiency and emissions can be seen across the board:
The information for 2011 covers 888 million t of cement production (25% of global cement production or 55% of production outside of China). The 2011 data on China covers 106 million t of cement, which accounts for around 5%. In order to ensure that the database is a reliable source of information, 95% of the data is verified independently at participating company level.
This year, GNR also includes country reports on Thailand, Morocco, Philippines and Egypt, which outline emission mitigation initiatives on a national level.
"GNR demonstrates how an effective measuring, reporting and verification system can be developed and managed for and by an entire industry sector. 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. It is also accessed widely by policy-makers, analysts and other interested stakeholders," said Philippe Fonta, WBCSD Managing Director.
