This article in yesterdays paper gives the evidence for low emission zones. I live in Bromley, one of the outer London boroughs effected. I support the scheme and was financially effected by it. We had two 20+ years old cars, we kept on the road because I could still work on them.
But living by a busy road I am very aware of how bad air quality can be and seeing the effect of it on people with respiratory issues I realise how selfish I was.
I replaced the cars with one and spent £6k, fortunately I could afford that. I scraped the old cars and got £600.
I’m old enough to remember the smog in the 50s , going to school with a scarf over my mouth and the dirty patch in front of where I’d been breathing through. That smog killed lots of elderly people. The gases ULEZ is going to reduce are invisible but just as deadly to vulnerable individuals.
