BT, as N3 Service Provider, has won the Innovation and progress: Sustainability category at the Guardian Public Services Awards 2011 for the N3 Managed Video Conferencing Service, which has reduced the NHS's greenhouse gas emissions by 150 tonnes and saved trusts more than £1m. The service links staff and patients remotely, avoiding the need for face-to-face consultations and expensive travel costs. It has been of particular use in connecting consultants working in multidisciplinary teams, such as cancer networks or stroke clinics.
