Fuel oil

Our consumption of fuel oil does not make a significant environmental impact.

We use fuel oil in two main ways:

• Diesel for our emergency generators at cell sites.
• Oil for heating our buildings.

Diesel generators are used only in emergencies or for very short periods of testing and the consumption is very low.

We have been trialling a much more efficient LPG-powered alternative generator at some of our cell sites.

Fuel oil consumption^a and CO₂ emissions^b (tonnes)

a) 2004/05 data for Manx Telecom and Airwave only. 2005/06 data for Manx Telecom, Airwave and O2 UK only.

b) Factors used to estimate CO₂ emissions: Diesel 1 litre = 2.63 kg CO₂; Fuel oil 1 litre = 2.69 kg CO₂ (Defra, 2005)
