TalkTalk has significantly reduced the carbon footprint of its network, buildings and infrastructure over the last four years, it has been claimed.

Gary Steen, Chief Technology Officer at the broadband provider, explained that emissions were reduced from 29,143 tons of Co2 to 19,291 tons between 2010 and 2014 - a drop of 34 per cent.

"That’s 9,852 fewer tons of carbon emissions every year, the same amount of carbon as 4,782 ‘average’ households would generate in a year," he noted.

"During the last year the amount of energy we use - gas and electricity - fell by 8.3 per cent."

Mr Steen said TalkTalk has achieved this while increasing the capacity of its next-generation network to meet the ever-growing demand from broadband customers.

He revealed that, on average, TalkTalk homes now download 44GB of data every month, rising to more than 100GB for fibre customers.

Mr Steen added that, since 2010-2011, the firm has increased bandwidth by 218 per cent while still reducing the carbon footprint of its internal data centres and offices.

"This has been achieved by improving the way our buildings are run and keeping a close eye on energy usage, using free air cooling in data centres where available by switching from air conditioning to circulating filtered air from outside, and by getting everybody at TalkTalk to commit to energy saving measures," he noted.

Mr Steen said TalkTalk is committed to a 70 per cent reduction on its 2010-2011 carbon footprint by the end of the decade, as the company looks to bolster its green credentials.
