County Down Britain's worst polluter
Updated on 23 November 2007
Britain's worst polluting local authority has been revealed as County Down, in Northern Ireland.
A study by the Energy Saving Trust combined its own figures on car emissions with Defra's figures on the amount of carbon produced by individual households to measure the emissions of every local authority in the UK.
County Down has an average carbon emissions of 14.5 tonnes a year for every household. At the other end of the scale, the City of London is the cleanest in the country, producing just 4.6 tonnes of carbon emissions a year.
