Most of Britain's major cities pledge to run on green energy by 2050

Leaders of more than 50 Labour-run councils sign pledge to eradicate carbon emissions ahead of Paris climate talks

Most of Britain's major cities will be run entirely on green energy by 2050, after the leaders of more than 50 Labour-run councils made pledges to eradicate carbon emissions in their areas.

In a highly significant move, council leaders in Edinburgh, Manchester, Newcastle, Liverpool, Leeds, Nottingham, Glasgow and many others signed up to the promise ahead of the crucial international climate talks that will take place next month in Paris. Labour said this would cut the UK's carbon footprint by 10%.
