This month I published a report evaluating the improvements in London’s air quality between 2016 and 2020 using data from London’s air quality monitoring network and modelling from King’s College London. The requested data is included in this report and is available online here: https://www.london.gov.uk/what-we-do/environment/pollution-and-air-quality/air-quality-london-2016-2020.
Key findings from the report include that since February 2017 there has been a 44 per cent reduction in roadside nitrogen dioxide (NO2) pollution in the central London ULEZ, with 44,100 fewer polluting cars being driven in the zone daily. There has also been a 97 per cent reduction in the number of state primary and secondary schools that are in areas exceeding legal limits for NO2, falling from 455 in 2016 to just 14 in 2019. For the first time, parts of London meet the World Health Organization (WHO) recommended limit for particulate matter (PM2.5).
