My Department did not meet the sustainable operations target on the Government office estate to reverse the then upward trend in carbon emissions by April 2007. The target related to the Department’s offices which increased substantially in number through the inclusion in the figures of the national probation service estate. After allowing for this, an increase in emissions of 12 per cent. occurred. There are a range of other factors that need to be taken into account, including density of occupation, IT provision and use of air-conditioning across the estate.
