London Air Pollution

Air pollution causes serious disease and early deaths. All Londoners currently live with air quality below WHO standards. Most of London's air quality problems are linked to vehicular transport. Poor people living, studying and working by major roads, are particularly at risk. Sadiq Khan and Maria Neira (Mayor of London and WHO Director, Public Health, Environment and Social Determinants of Health) opine that the greatly expanded ultra low emissions zone (ulez) will greatly improve air quality in the capital (https://www.theguardian.com/commentisfree/2021/oct/24/death-and-illness-from-toxic-emissions-are-avoidable-cop26-must-deliver-bold-action). Khan and Neira hope that the new ulez will get more people cycling, walking, using public transport and/or investing in electric vehicles. It is to be hoped, of course, that people with physical challenges (who cannot cycle, walk, use public transport or drive) will also be catered for. One must, however, note that not every city/town in the UK, has London's scope for change. I also seem to remember a previous mayor of London who sat on air pollution figures in the capital. Pollution was especially bad around schools. I wonder what happened to him?
