I was reading about the upcoming Manchester CAZ the other day which doesn't come into effect until May 2022 as to give local hauliers/taxi/coach firms & van fleets time to upgrade their fleets to cleaner compliant vehicles.
Private cars are not being banned in the Manchester CAZ.
Van operators can now access up to £4,500 towards the replacement of a vehicle – £1,000 more than initially proposed – and Greater Manchester Hackney Cabs can get up to £10,000. HGVs can now get up to £12,000 towards replacement, nearly three times more than was initially offered, and coaches are now eligible for £32,000.
What I did find interesting was they've already made an extension to the CAZ before it even begins to incorporate the Trans-Pennine routes A426 Snake pass & A57 Woodhead Pass which will carry the same restrictions as the city centre for older non compliant vehicles which will have to go the long way round using the M62
