Note: Water consumption data is collected under the categories of fresh water, brackish water and sea water. There has been no brackish water consumption since before 2011. Some fresh water used by Cairn’s activities is produced by reverse osmosis from sea water. This data is included under sea water as this is the source of the water.

Note: *The categorisation of some sea water data in 2011 and 2012 has been corrected, e.g. moved from brackish water to sea water for 2011 (it had previously been recorded under brackish/sea water and when the categories were broken down it was incorrectly categorised as brackish water) and moved from unspecified to surface water sources in 2012.

Note: There has been no hydrocarbon production since 2010.

 

Note: Water effluent data includes domestic water effluent discharged from vessels but not from taps in offices. Domestic water effluent discharge from vessels is usually based on estimation as vessels do not often have discharge metres.

Note: Data has been provided for individual countries where there has been relevant water consumption or effluent and discharges to water.
