Nationwide is using a bespoke version of the Carbon Trust's 'Empower' tool, featuring virtual representations of locations, accompanied by energy efficiency tips tailored for the building society.

Advice will be provided across a variety of business areas, including branches and administration centres, as well as transport options for getting to and from work, details on teleconferencing, and recommendations on how employees can take action in their own homes.

The building society's 15,000 employees will be encouraged to pledge how they will cut carbon and be provided with additional learning tools such as quizzes and myth-busters. Information and reporting on pledges will be used to help Nationwide target the most effective places to change behaviour, as well as monitor expectations and progress.

Lynn Forrester, sustainability manager, Nationwide, says: "We are pleased to have had an opportunity to work with the Carbon Trust to develop a tailored programme which is relevant to Nationwide and we are confident 'Empower' will help actively engage and inspire our employees on our journey towards a lower carbon future."
