BT is taking it's green pledge further by encouraging more than a million customers to switch to online billing by the end of the month.

The telco uses 60 tonnes of paper each year and aims to reduce the impact on the environment. The company is also giving something back by planting more than 250,000 saplings - spanning the equivalent of 250 football pitches - around the UK.

BT partnered with the Woodland Trust in 2005 and pledged to plant a native sapling for every customer that signed up to the new service. The telco’s move to more digital dominated services represent the trend to move away from the need to produce paper documents.

"Many companies have started to conduct their customer communications via the Internet, including their billing, but the dramatic success of BT's e-billing scheme has been boosted by the support we've had from the Woodland Trust", said Gavin Patterson, managing director of BT Retail's consumer division.
