A monthly meeting is held by mine energy champions, during which<br />

progress against targets and new projects regarding energy and the<br />

environment are discussed.<br />

By the end of 2013, a climate adaptation plan for <strong>Kumba</strong>, detailing<br />

the risks and associated mitigation plans, will have been put in place.<br />

This will be supported by the development of a regional climate<br />

model to identify key site adaptation requirements.<br />

The total energy consumption for the group rose by 10.7% to<br />

7,046,889 gigajoules (GJ) in 2011 (2010: 6,365,277GJ), owing to<br />

rising waste stripping requirements and expansions. Energy intensity<br />

also rose by 20% to 0.177GJ per tonne of ore. Of the total energy<br />

consumed, electricity purchased accounted for 26% while 74% was<br />

generated from fossil fuels.<br />

Anglo American plc uses its Group Technical Standard as an energy<br />

and emissions management standard for the Group. Gap analyses<br />

for full compliance were conducted during the year by Anglo<br />

American Technical Services at all of <strong>Kumba</strong>’s operations.<br />

Sishen mine’s compliance was found to be 68% in March and 88%<br />

�� �������� ����� ���������� ������ ���������� ���� ���� ���<br />

to 68% over the same period, and Kolomela mine’s compliance<br />

increased from 28% to 40%. Full compliance is targeted for<br />

December 2012.<br />
