For 2009 the data below has been formally verified by Lloyd's Register Quality Assurance (LRQA). Their assessment assures that data monitoring and calculation processes generate accurate and complete data, and that data management systems are robust. The LRQA assurance statement explains the assurance process and their conclusions.

Note:
(1) Emissions figures are based on net MWs owned during the year.
(2) The emissions intensity figures above take into account the significant quantities of energy used to produce desalinated water and steam at various plants. Figures for equivalent electricity output at these plants have been calculated to reflect this and provide a correct representation of our emissions intensity.
(3) Data on reportable environmental incidents and prosecutions is provided for those assets where we have operational control. In addition, note that the European Wind Portfolio is currently excluded from this reporting.
(4) Reportable environmental incidents are incidents where the reporting of an exceedance of emissions limits to the relevant authority resulted in a requirement to review existing operating practices.
(5) Data on accident frequency rates and fatalities is provided for those assets where we have operational control. In addition, note that the European Wind Portfolio is currently excluded from this reporting.
(6) 100% of all donations included for subsidiaries, joint ventures and associates, regardless of ownership percentage.
Prior to 2005 International Power presented all environmental data on a gross ownership basis. Since 2005 all data has been presented on a net ownership basis. View the historical gross data.
