Government buildings are emitting more carbon than ever before - with Gordon Brown's Treasury the worst offending department - according to research by the Liberal Democrats.
The results show:
Commenting, Liberal Democrat Shadow Environment Secretary, Chris Huhne MP, said "The Government needs to go green, not brown. The Chancellor likes to talk about climate change, as he did in the pre-budget report, but he is not practising what he preaches.
"Given all the Chancellor's hot air, it is particularly ironic that the Treasury has seen a big rise in it's own emissions.
"This is not just lousy for the environment, it is also bad news for taxpayers, as the Treasury is just burning money as it leaves lights, computers and heating on late to no purpose.
"Yet again Gordon Brown has failed to show the leadership on climate change which is needed.
"The Government urgently needs to make the green switch itself, starting at the top."
