The Department has 112,000 staff in 1,221 buildings. Due to the scale of our operations we do not collect information on the commuting choices of our staff, and have no plans to do so. It is not possible to estimate the number of staff using public transport to commute, as this would be different in every building. But a variety of information is provided to staff to help them make personal choices about their commuting journeys, via our intranet site and Sustainable Development staff magazine—such as links to ‘Transport Direct’ and suggestions on car-sharing schemes. Businesses are encouraged to operate a green travel plan at those sites where one would be beneficial.
