published on our website by mid-2011.
Already in 2009, Holcim achieved its own target of
reducing net CO2 emissions per tonne of cement by
20 percent compared to 1990 levels. In 2010, emis-
sions were reduced by approximately 21 percent.
Holcim is committed to further progress: It has set
itself the target of reducing CO2 emissions per tonne
of cement by 25 percent until 2015 compared to the
reference year 1990.
Holcim is using alternative fuels and waste materials.
The recovery of energy and materials conserves natural
resources and reduces global CO2 emissions.

Data excludes own power generation.
Taking 2004 as reference year, Holcim has committed
itself to reducing specific emissions of dust and
nitrogen oxides (NOx) by 20 percent by 2012 and 2013,
respectively. By 2010, NOx emissions had already been
reduced by 17 percent. By 2010, specific sulfur dioxide
(SO2) emissions were reduced by 62 percent; the
original target of 20 percent was met as long ago as
2006.
New certification system for alternative fuels
and raw materials
Holcim is applying the most advanced technologies
to make use of alternative fuels and waste materials.
The recovery of energy and materials conserves natural
resources and reduces global CO2 emissions. At
the same time, it helps to lower production costs and
mitigate part of the waste problem, especially in the
