BT, the UK's biggest telecommunications operator, is to take part in and support the Green Touch initiative launched by Bell Labs to cut the energy use of the IT sector to one-thousandth of its present consumption.
Mike Galvin, managing director of research at BT, said the company is "delighted" to participate in and support Green Touch and will contribute to plans for reducing carbon emissions across the communications supply chain.
"To be able to rise to this significant challenge the industry needs to work together to produce radical solutions. We will be encouraging all those we work with to take part," he said.
BT has a history of environmental awareness. In 2004, it announced a deal with Npower worth several hundred million pounds for energy from sustainable resources.
It has also hosted events about how to reduce energy consumption and produced a guide to what businesses can do to cut and offset their energy use.
