"ban diesel, as 60 years ago coal was banned successfullly"

Simon Birkett, Founder and Director of Clean Air in London, said:

"Frankly, the only way to protect public health and comply fully with legal limits is to ban diesel from the "most-polluted areas.  Let’s do so positively, by encouraging positive measures such as active travel (e.g. walking and cycling) and triggering a massive shift to fewer, cleaner and greener vehicles.  By doing so, the UK can be a world leader again as it was so successfully 60 years ago after banning coal burning in cities."
