The National Grid is rolling out audio and web conferencing to save money, boost productivity and cut carbon emissions.

Communications firm MeetingZone is working with the energy provider to promote the system to employees and encourage them to register for a conferencing account.

The tools have boosted collaboration and helped the company fulfill its environmental responsibility, said Sameira Ahmed from National Grid's IS and telecoms supply chain management.

“The system enables us to deliver business communications tools to approximately 12,000 of our employees in the UK, allowing them to quickly and easily communicate and collaborate with who they want, when they want, regardless of location," he said.

"We are committed to help tackle climate change and are continually looking at ways in which to make sure that business is sustainable and responsible. A reduction in business travel results in a reduction of our carbon footprint," he added.
