O2 has become the first operator to be officially certified with the Carbon Trust Standard.
The operator said the reward was recognition of its commitment to reduce its carbon footprint and the 15 per cent reduction in energy consumption achieved over the past three years.
Over that period, O2 has made a £1.4 million investment in smart metering technology to accurately monitor real-time energy consumption across cell sites, retail premises and offices and installed more energy efficient technology in the O2 network.
It has also removed air conditioning on certain cell sites and replaced them with cooling fan boxes, used LED lighting in retail stores, advanced boiler controls for all main gas boilers and reduced PC monitor standby times.
As a result, 47,000 tonnes of CO2 have been saved.
Telefonica O2 UK chief executive Ronan Dunne said: “We saw some of our early wins from simple initiatives such as changing heating and cooling patterns in the offices and contact centres and our awareness raising ‘Flick the Switch’ campaign targeting energy wastage.
“The results improved our bottom line, without excessive expenditure. Really, it’s all about listening to your people and suppliers, and addressing their needs with minimal energy consumption.”
The Carbon Trust Standard is the world’s first carbon award that requires an organisation to measure, manage and reduce its carbon footprint and make real reductions year-on-year. Unlike other schemes, organisations are rewarded for actions they’ve taken to cut carbon across their own operations.
