DEFRA provide guidance on sustainable operations on the Government estate, on the estates pages of the Government's sustainable development website:
http://www.sustainable-development.gov.uk/government/estates/index.htm
Additional guidance is provided by other parts of DEFRA and by other Government Departments:
(a) New buildings
(b) Retrofitting existing buildings
Government guidance on public sector construction and property asset management includes sustainable development considerations. Both OGC's ‘High Performing Property’ programme and ‘Common Minimum Standards for the Built Environment’ documents reflect Government's environmental and sustainable development targets and standards. Departments are also mandated to work with the Carbon Trust, using their carbon management programme.

DEFRA would expect Government Departments and agencies to reflect planning policy in developing their estate.

DEFRA have set up a Civil Service Travel Group to identify Government travel practices, and to assist Departments to travel in a more sustainable way when doing business. It also aims to place sustainability at the heart of all Government travel procurement and contract management.
