The UK's greenhouse gas output climbed 3.1 percent in 2010 as people used more gas to heat their homes amid colder weather and more nuclear plants were closed for maintenance, according to final government estimates published Tuesday.

The country emitted 590.4 million tonnes of CO2 equivalent of the six greenhouse gases (GHGs) covered by the Kyoto Protocol, up from 572.5 million tonnes in 2009, said the government report, revising an initial estimate made last year of 582.4 million.
