We follow the principles of the Greenhouse Gas (GHG) Protocol Corporate Standard to calculate Scope 1, 2 and 3 emissions from our worldwide operations.
The reporting period for emissions is October 2013 to September 2014, which is different to that of our Directors’ Report (January 2014 – December 2014). This is in line with Regulations in that the majority of the emissions reporting year falls within the period of the Directors’ Report.
We report emissions based on an operational control boundary. The scope of our reporting is in line with GHG Protocol, and covers Scope 1, Scope 2 and Scope 3 emissions. Reported Scope 1 emissions cover emissions generated from gas and oil used in Group buildings, emissions from UK company-owned vehicles used for business travel and emissions from the use of air conditioning and chiller/refrigerant plant. Reported Scope 2 emissions cover emissions generated from the use of electricity. Reported Scope 3 emissions relate to business travel undertaken by colleagues (by air, rail and in privately-owned or hire vehicles) and emissions associated with the extraction and distribution of each of our energy sources – electricity, gas and oil.
A detailed definition of these emissions can be found in our environmental criteria statement.
