Cement Sustainability Initiative data shows no change in CO2 emissions

Business News

2016 data published by the Cement Sustainability Initiative (CSI) from its “Getting the Numbers Right (GNR)” report shows no change in CO2 emissions in recent years.

The report uses information from 849 cement manufacturing plants around the world; both integrated and cement grinding units, representing 19% of global cement production.

Gross specific CO2 emissions from cementitious products rose slightly from 2014 and net specific emissions have remained the same.

However, the data shows considerable improvement since a baseline in 1990 with both metrics falling by over 15%.

Other notable figures from the latest report include an 11% year-on-year drop in clinker volumes to 606Mt in 2016 from 680Mt in 2015 and a 12% fall in cementitious volumes to 818Mt from 916Mt. Kiln fuel use, specific electricity use and the percentage of clinker in cement all rose slightly.

However, the percentage of alternative fuels used increased to 16.7% from 15.9%.

The GNR report presents information on energy efficiency and CO2 emissions from the worldwide cement industry. Participants use the CSI CO2 and Energy Accounting and Reporting Standard for the Cement Industry to provide information and 80% of the data provided is independently assured.
