O2 becomes the first network operator to certify carbon footprints with the Carbon Trust

25 June 2012 | News

O2 works together with the Carbon Trust to calculate and certify carbon emissions of voice and data services.

O2 carbon footprint

O2 has become the first mobile network operator to have carbon footprints independently verified by the Carbon Trust. Using our Footprint Expert software O2 calculated the greenhouse gas emissions embedded throughout the entire lifecycle of its voice and data services. 


Our aim is to develop the UK's most carbon-efficient network, putting our own operations under the microscope and looking for ways to reduce the footprint we leave on the world. By evaluating our impact in conjunction with the Carbon Trust we feel we are doing just that.

Gareth Rice, Head of Environment at O2

We congratulate O2 for becoming the first mobile network to have telecommunication service carbon footprints independently verified by the Carbon Trust. We look forward to supporting O2 in its Think Big ambitions.

Darran Messem, Managing Director of Certification at the Carbon Trust


Building on this work, O2 is planning to provide customers with the tools to calculate the CO2 associated with the services they use, providing comparisons with various activities, putting their every day CO2 impact into context.
