To ask the Prime Minister if he will list the flights he has taken since 2001; and what measures to offset the carbon emissions were taken for each flight.

The information requested could be provided only at disproportionate cost. All my travel is undertaken in accordance with the "Ministerial Code" and "Travel by Ministers", copies of which are available in the Library. Since 1999, the Government have published on an annual basis a list of all overseas visits by Cabinet Ministers costing in excess of £500. Copies of the lists are available in the Library. Information for 2005-06 is currently being compiled and will be published when it is ready.

All central Government ministerial and official air travel is being offset from 1 April 2006. Departmental aviation emissions are calculated on an annual basis and subsequently offset through payments to a central fund. The fund purchases Certified Emissions Reductions credits from energy efficiency and renewable energy projects with high sustainable development benefits, located in developing countries. In addition, offsetting my flights and those of Ministers in DEFRA has been backdated to 1 April 2005.
