⁽¹⁾ For 2008 calculations, the UK's grid rolling average conversion factor (DEFRA) was used for the first time. This change increases CO₂ as calculated from electricity by ~25%. As of 2007 this figure includes data from 100% of our UK occupied properties. An adjustment to meters newly installed in our London office has led to changes in data for 2007.

⁽²⁾ Employee numbers taken from average security headcount where available (recorded 11am at main offices) and from workstation numbers at smaller offices.

⁽³⁾ N/A = Not available

⁽⁴⁾ Live contracts are an indication of business on our books.

⁽⁵⁾ Data is collected from rail, air and road transport.

⁽⁶⁾ Occupied properties and business travel encompasses Legal & General's direct carbon footprint and is used for subsequent resulting overall CO₂. Resulting CO₂ per employee is based on total UK staff, not office based staff due to inclusion of travel CO₂.
