The latest figure was down 5.25% from the "base year" of 1990, the data show.
Emissions of all six greenhouse gases covered by the Kyoto Protocol were up about 0.5% from 2005.

The UK produced total greenhouse emissions of 658.10 million tonnes CO2 equivalent last year. This was down about 15% from the 1990 Kyoto Protocol base year figure of 775.20 million tonnes.
UK carbon dioxide emissions for 2005 showed a negligible difference from 2004, falling from 554.6 million tonnes to 554.2 million tonnes.
