The 639.4M tonnes carbon dioxide equivalent is down from 652.3M tonnes in 2006.
The statistics also show that in 2007, UK net emissions of Carbon Dioxide (CO2) were provisionally estimated to be 543.7M tonnes; two per cent lower than the 2006 figure of 554.5M tonnes.
The decrease in CO2 emissions resulted from fuel switching from coal to natural gas for electricity generation, combined with lower fossil
fuel consumption by households and industry.
"These figures show we are making progress in cutting emissions and are on target to go beyond our Kyoto targets," said Secretary of State for the Environment, the Rt. Hon. Hilary Benn.
"But there's much to do at home and abroad if we are to going to avert dangerous climate change. We need to see a major change across the whole of the UK economy if we are to meet the ambitious emissions reduction targets set in the Climate Change Bill.
To aid this, the Government will develop carbon markets and promote the development of low carbon technology, while continuing to work to get international agreement on global emissions targets."
