More than 40 towns and cities in the UK have unsafe air pollution levels, according to the World Health Organisation. Not just a problem for our climate, but for public health too.

On this week's episode of Sky News ClimateCast Katerina Vittozzi takes Anna Jones on a trip around Greater Manchester.

It comes as the region's leaders ask the government to pause and review parts of the Clean Air Zone plan. Katerina explores why, as she visits Shepherdess Jade Hutchinson (and her sheep) who has been protesting against the zone.

12-year-old Maksim however, says air pollution is hindering his asthma and the clean air zone is needed now more than ever.

So, can Manchester and other cities make the green transition without damaging livelihoods? We ask Mayor of Greater Manchester Andy Burnham.
