      Energy is becoming an increasingly important issue and is receiving increased interest due to the realization that fossil fuel resources required for energy generation are finite and that climate change is linked to carbon emissions (Baños, 2010). This realization has led not only to increases in energy costs (refer to Appendix 10.1 for rises in costs for XNA), but also to action to reduce energy consumption and greenhouse gas (GHG) emissions. In Australia, action has already commenced with the government agreeing to reduce Australia’s GHG emissions through the international agreement of the Kyoto Protocol. This has subsequently led to the implementation of government run energy and GHG reduction programs, as well as the government implementing financial incentives for businesses to reduce their carbon emissions through the impending carbon tax.

      For businesses, these reduction programs, rising energy costs and impending carbon tax are considerable reasons to become accountable for energy consumption and to reduce their GHG emissions. Mining companies, as highly energy intensive activities (Kenjile 2004), have even more reason to become accountable due to the significant associated capital costs (Environment Australia 2002). A mining company that uses a substantial amount of energy and therefore is interested in reducing their energy consumption and GHG emissions is Xstrata Nickel Australasia (XNA) for their Cosmos and Sinclair Nickel operations.
