In 2014 we changed the intensity ratio we report on from a financial to a production-based one. The ratio of our total GHG emissions reported on an operational control-based boundary to gross production was 0.25teCO2e/te production in 2014. Gross production comprises upstream production, refining throughput and petrochemicals produced. In 2013 we reported the ratio of our total GHG emissions on a BP equity-share basis to adjusted revenue of those entities or share of entities included in GHG reporting. This was 0.15kte/$million. Adjusted revenue reflects total revenues and other income, less gains on sales of businesses and fixed assets.
