Lafarge hit emissions target two years early

Global building materials group Lafarge, owners of the Blue Circle cement brand, have reached their first has CO2 emissions reduction objective two years in advance.

Absolute emissions in the industrialised countries have gone down 12.5% over the 1990-2008 period. The original objective was a 10% reduction between 1990 and 2010. The other objective - that of reducing net CO2 emissions per metric ton of cement by 20% - saw a reduction of 18.4% at the end of 2008, compared with 16% in 2007.

98% of Lafarge's CO2 emissions come from its cement business. These emissions come in part from the chemical reaction of lime to heat, while the other part comes from the fossil fuels used to fire the kiln.

Lafarge have committed to a policy of reducing their and among the measures taken are:
  • the continuous improvement of the energy performance of factories,
  • the use of alternative fuels such as industrial residues or biomass, partly replacing the fossil fuels used to fire cement kilns
  • and the use of cement additives that can partly replace clinker in cement production. Mostly, these are slag and fly ash, which are by-products of the steel industry and coal-fired power stations, respectively.
