The global cement sector has continued to reduce the amount of CO2 it emits per tonne of cement, according to new data published by the World Business Council for Sustainable Development’s Cement Sustainability Initiative (CSIi). Improvements in the sector have been attributed to modern blending methods, alternative fuels and improved new kilns.
As well as showing a reduction in CO2 per tonne of cement produced, the data also reveals a reduction in absolute CO2 emissions from companies reporting to the CSI database. These dropped for the first time since data has been gathered, from 596Mt in 2007 to 577Mt in 2008. This reduction reflects the impact of the economic downturn and global slowdown in construction activity.
The information gathered by the CSI covers cement production in 2008, as there is a one year embargo on data release to comply with anti-trust regulations. CSI’s voluntary database now covers a third of global cement production.
