Leaders of more than 50 Labour - run councils in the UK , including Glasgow , Birmingham , Manchester , Liverpool , have made a pledge to eradicate carbon emissions in their areas by 2050 by sourcing 100 % green energy , a move which Labour believes will cut the UK 's carbon footprint by 10 % . The pledge will mean green transport , an end to gas heating and a commitment to insulate homes in cities across the UK . Miliband, who was energy secretary under Gordon Brown, said Britain should show leadership and send a clear signal to businesses by building on its existing target of cutting emissions by 80% by 2050 under the Climate Change Act. " Where Labour is in power we will push for a clean energy boom even if the government will not " , says Lisa Nandy , Shadow Energy Change and Climate Secretary , who is coordinating the pledge . Some Labour - led London boroughs , including Southwark , Lambeth and Croydon have also signed the promise and similar pledges have been signed by leaders of other towns and cities worldwide including New York , Sydney and Copenhagen .
