| Atmospheric emissions and other environmental impacts |
|
Monitoring and decreasing atmospheric emissions in cement manufacture are Group priorities. Our target, to reduce global average specific NOx, SO2 and dust emissions by 20% by 2010 compared to 2004 levels, encourages continuous improvement. |
||||
|
Controlling atmospheric emissions Ongoing investment to upgrade plant equipment as well as regular maintenance and training are required by our emissions monitoring and reporting (EMR) standard. At the end of 2007, the implementation rate of the continuous emission monitors at kiln stacks (excluding India) was 83% (2006: 83%). We make knowledge gained through this work available to local test houses and regulators. |

Other atmospheric emissions – dust, NOx, SO2 |
||||
|
||||
|
||||
We have already achieved a 20% reduction in specific SO2 emissions and are on track to achieve a 20% reduction in specific dust emissions by 2010, but have to increase our efforts to reduce our NOx emissions.

In line with our Cement Sustainability Initiative commitment, data are also reported on grams per tonne of clinker. |

Transport Given that cement and aggregates are heavy, low-price, bulk products, transport choices are controlled primarily by cost considerations. These increasingly take environmental aspects into account and where possible, Group companies embrace opportunities for optimizing their distribution channels. |
