Travel and transport

Our most significant transport emissions occur through network maintenance, retail distribution – both undertaken by contractors – and business travel.

In the UK, we are working closely with our main logistics supplier DHL to reduce the impact of their road transport. This includes a new pilot project which will see our parcels being delivered by vehicles powered by bio-fuel.

In 2003/04 we began to measure the energy consumption of our main third-party contractors in the UK to better understand O2’s extended environmental effects.

Road transport - total km^a travelled and total CO₂ emissions^b

a) Data for company car use includes an element of private miles for Germany.

b) Conversion factors used: Medium petrol car (1.4 - 2.1 litres) 1 km = 0.19kg CO₂; average diesel car 1km = 01.7kg CO₂ (Defra 2005). Dual fuel/LPG vechicles have been assumed to produce approximately 20% less CO₂ than diesel vehicles (UK Dept for Transport). Diesel heavy goods vehicle 1km = 1.18kg CO₂ (Defra 2005).
