1

Other energy sources include for example heating oil, biofuel energy, propane and butane. The increased consumption of other energies in 2011 resulted from the inclusion of additional other energy sources (e.g. naphtha and methanol) into the indicator scope.

2

Water use in 2012 increased due to newly installed air separation plants in China, which mainly use sea water in their processes.

3

Water consumption relates to drinking water and industrial water used. Once-through water is drawn from a natural or other sources, solely warmed and ultimately piped back to the original source at a temperature not posing any risk to the surrounding ecosystem.
