The environmental impacts of our activities are different for every operation and site we manage. Extracting diamonds from different kimberlite deposits requires a variety of mining methods. These include underground mining, open-pit mining, coastal and beach mining and deep-sea vessel mining. Kimberlite deposits and mines also exist in different ecosystem types. These include African savannah, the Karoo biome, Namib desert, the tundra of Canada and underwater marine ecosystems associated with coastal and deep sea mining in Africa. Our mines also vary significantly in age, as well as reserves and depletion rates. These different characteristics influence our environment impacts and therefore our environmental programmes and performance.
	This wide range of operating contexts means each mine needs its own unique environmental management strategy. In all cases these strategies are derived in accordance with our common Values, Principles and Environment Policy. Legal compliance is a minimum level of performance. A key challenge in 2006 and beyond is to build further consistency and learning across the family of companies and ensure continuous improvement in our environmental performance. Our key vehicle for addressing these challenges is our strategic environmental initiatives programme. Diamond mining is relatively less harmful to the environment than other extraction activities. Deposits tend to be naturally demarcated by the margins of the kimberlite pipe. Very few hazardous substances are used in the diamond production and treatment process. There have been no major environmental spills or fines at our operations since 2003.
