If we are aiming to increase air quality, then geographic taxes seem fine. And by that I mean hike London's congestion zone charge up x10 for all vehicles with emissions. And expand it back to cover a more sensible portion. And then have every city implement the same thing. And when the lobbying starts against it, how about someone holds their nerve for a change. Yes businesses need deliveries but they don't need to make them with polluting vehicles, that's a choice influenced by cost. EDIT: BY incredible coincidence I just received an email from TfL on exactly this! ULEZ is coming to central London in the same area as the Congestion Charging zone from 8 April 2019. It will operate 24 hours a day, every day of the year. Vehicles will need to meet the new stricter emission standards, or you will need to pay the daily ULEZ charge. This is in addition to the weekday Congestion Charge. £12.50 per day for cars, motorcycles and vans (under 3.5 tonnes) £100.00 per day for heavier vehicles, including lorries (over 3.5 tonnes) and buses/coaches (over 5 tonnes) From 25 October 2021, the ULEZ will be expanded to include the inner London area bounded by the North and South Circular roads. Great news!
