Upon becoming Greater Manchester’s first elected mayor, Andy Burnham announced his ambition to make the city-region one of the greenest in Europe. In his Mayor’s manifesto, the former MP and Labour leadership candidate, committed to “a new, accelerated ambition for Greater Manchester on the green economy and carbon neutrality”. If achieved, Manchester would be transformed from one-time poster city for Britain’s dirty past to a decarbonised oasis in the post-industrial north-west of England. What it will take to realise this vision is the topic of a “Green Summit” to be held in Manchester on March 21.
