Information on environmental performance is supplied to the Office of Government Commerce (OGC) and the Sustainable Development Commission (SDC), in accordance with the Government targets set for Sustainable Operations on the Government Estate (SOGE). Detailed information is available on the respective OGC and SDC websites. As a result of various measures taken by the Department for International Development (DFID), the carbon emissions after allowing for weather correction have reduced by 15 per cent. over the last two years. All energy is purchased via central Government framework contracts arranged by the Office of Government Commerce, and the variation in expenditure is partly attributable to the changes in unit costs under these contracts.
