The primary data have been collected from theReceived in revised formsustainability reports published by copper producing mines, operations and companies. The mines17 September 2012analysed in this paper are from Australia, Chile, Peru, Argentina, Laos, Papua New Guniea, South Africa,Accepted 20 September 2012Turkey, Finland, the USA and Canada. The typical range of energy intensity was found to be 10e70 GJ/Available online 3 October 2012t Cu, with an average of 22.2 GJ/t Cu. The range of GHG emissions was 1e9tCO -e/t Cu, with an2average of 2.6 t CO -e/t Cu. The large variation exists largely due to the form of copper produced, ore2Keywords:grade, sources of fuel and electrical energy, and to a lesser extent the reporting methods andCopperprocedures used by the companies. The water footprint averages 70.4 kL/t Cu but can range fromEmbodied energyseveral kilolitres to up to 350 kL/t Cu. Variation in water intensity is generally due to inconsistenciesGreenhouse gasesWater in reporting method, the geographical location of the mining operations, limited economies of scale ofLife cycle assessment production site, and the climate type (i.e. arid regions in Australia and Chile or temperate to sub-arctic climates in Canada or Finland).
