At last, it appears, someone in the UK is getting serious about air quality. It has been reported (https://www.bbc.co.uk/news/uk-england-birmingham-44524898) that Birmingham is to introduce charges for people entering specified clean air  zones with high polluting vehicles (particularly certain cars, trucks and buses) on the calculation that the polluter should pay. Although this is a reasonable step (air quality causes premature deaths, expensive-to-manage illnesses and lost economic activity) it might well be seen by the relatively wealthy as simply a local 'tax' (and people in some shops have already complained that it might hit trade). Certainly, there needs to be a rapid improvement in non-polluting public transport in the area. The Scandinavians, as is often the case,  established this type of arrangement years ago!
