The Treasury has been measuring the carbon emissions for the office estate since 1999.
The volume of emissions for the building for the last period measured (2005/06) was 1,189,241.93 kg C02, which is the weather corrected annual carbon emissions. All electricity used is generated from renewable sources.
Work is underway to accurately calculate emissions from air travel. The Treasury will contribute this year to the carbon-offsetting fund, coordinated by the Department for Environment, Food and Rural Affairs, to offset emissions from flights on departmental business from April 2006. On the basis of estimated air emissions of around 1,629 tonnes per annum, we would expect to pay £32,577 per annum.
Opportunities to offset other emissions will be explored once levels have been reduced as much as possible.
