Performance Summary – Environment
Environmental performance data is presented on a financial year basis from 1st April to 31st March (unless otherwise stated). Where necessary data has been restated, for example to reflect changes in the business (e.g. divestments and site closure), to take account of changes in best practice methodologies for calculating emissions or in response to recommendations made by our assurance provider.
Global warming potential (GWP) includes Scope 1 and Scope 2 emissions. GWP data for the last five years has been restated from that presented in the group’s Annual Report which was published in June 2010. These restatements have been included following recommendations made during the assurance process for this Sustainability Report. These recommendations included the use of North American regional carbon intensity values. GWP data presented in the Annual Report showed an increase from 2008/09 to 2009/10 whereas the restated data in this report shows GWP has fallen slightly. This is a result of the year to year change in the proportion of the group’s emissions from operations in North America.
