Average Brit has already caused a Kenyan's annual carbon emissions
The average Briton has so far in 2012 been responsible for the same amount of emissions as a typical Kenyan will be over the whole year.
According to the World Development Movement (WDM) Kenya's annual per capita carbon emissions is 0.293 tons, while the UK's are 8.351 tons.
So by today (January 13) the average British resident will overtake their average Kenyan counterpart.
The charity used figures from the US Energy Information Administration to work out per capita carbon dioxide emissions for the two countries.
WDM director, Deborah Doane, said: "This is a stark reminder of the UK's responsibility for climate change.
"Developing countries like Kenya make almost no contribution to the problem, yet they face the worst consequences.
"Meanwhile the UK is failing to make sufficient emissions cuts or to meet its obligations to help poorer countries cope with the effects of climate change."
The campaigning group is calling on the UK government to honour its promise to be the 'greenest government ever' by meeting its commitments to reducing emissions under the Climate Change Act.
