SUSTAINABILITY REPORT 2011

Greenhouse gas emissions – CO
2
emissions
Climate change and global warming have broad implications. To address issues related to climate change and working to ensure its sustainable development,
MYTILINEOS Group is planning initiatives aimed, among others, at measuring and at controlling and reducing the volume of carbon dioxide (CO
2
) emissions from
its activities. During 2011, the Group continued its efforts to publish information on total CO
2
emissions for all its companies. The results, which are shown
in the table that follows, cover 60% of the Group Companies and fall short by 40% from the target which had been set in 2010. As a result, and until data
on carbon dioxide emissions from the other companies become available, it is not possible to set specific targets for the overall reduction of CO
2
emissions.
Detailed information on emissions CO
2
and on the methods used to determine them are presented in the Report’s individual Company sections on ALUMINIUM
S.A., DELPHI-DISTOMON S.A. and PROTERGIA S.A.
Significant spills
Our systematic efforts to prevent spillage of hazardous materials are directly related to the Group’s compliance with regulations, the financial risk from the loss
of raw materials, the cost of rehabilitation and to the risk of regulatory measures being imposed. During 2011, a total of 33 such incidents were recorded by
DELPHI-DISTOMON S.A., involving the spillage of lubricants on the soil in underground tunnels due to the breakdown of machinery weighing nearly 5 tons. The crew
and the machinery operators responded immediately, dealing with the incidents and collecting the contaminated soil. No high or medium gravity environmental
pollution incidents occurred and no incidents were reported involving the spillage of hazardous materials to the environment by any other Group company.
Waste disposal
The production processes of the Group Companies produce liquid and solid waste, which are separated at the source and collected by suitably licensed
professionals for management. During 2011, the Group Companies delivered around 1 million tons of waste to:
1 million tons of waste to:
1. Landfills (69.6%, down 3 percent points from 2010).
2. Disposal at sea (21%, down 1 percent point from 2010).
3. Utilisation / reuse (9%, up 5 percent points from 2010).
4. Recycling (0.3%, up 0.2 percent points from 2010).
In more detail, the categories and quantities of waste produced by the Group, by disposal method, are as follows:
