There was an interesting article just published by Shazad Sheikh on measuring air quality in London. He purchased an ELITech Air Monitoring device and used it on the streets of central London and in underground and train stations. The device measures particulates (PM 2.5 and PM10) which are known to be air pollutants that are the most hazardous to health and the results were most interesting – see his article here: https://browncarguy.com/2023/07/03/ulez-air-quality-test-pt-1-2/
It shows that in general the air quality on the streets is unlikely to be a major health hazard as Sadiq Khan claims but the contrary is true in stations.
Note that the device does not measure NOX gasses but these are unlikely to be a health hazard anyway despite what some people claim because they are easier to measure.
You can purchase one of these devices and test the local air quality in your own neighbourhood which I plan to do (Shazad provides a discount code you can use).
Meanwhile Sadiq Khan ignores the problem of very bad air pollution on London’s underground while wanting to penalise car drivers when they are not a significant problem. This is driven by money considerations of course. He can extract money from drivers with ULEZ schemes while cleaning up underground air quality would cost him money.
The Plan to Stop Driving in London
It is very clear that Sadiq Khan and his supporters in the environmental lobbyists are on a mission to stop all driving in London. This was made clear in a document entitled “Next steps for reducing emissions from road transport” published by TfL last year but not widely publicised – see https://content.tfl.gov.uk/next-steps-for-reducing-emissions-from-road-transport.pdf .
This is a call to stop all CO2 emissions from transport in the name of stopping climate change – an impossible task. The document tries to justify expansion of the ULEZ, charges on all vehicles other than zero emission ones and pay per mile charging on all vehicles. It’s an unscientific attack on the use of road transport in general. Read it and be horrified by what is planned!
Only removing Sadiq Khan and the current management of TfL will stop, this unjustified attempt to change our way of life.
Meanwhile the hearing in the High Court of the judicial review challenging the ULEZ expansion commences today (see https://www.bbc.co.uk/news/uk-england-london-66094244 ). It could be some weeks before a judgement is given and the outcome is uncertain.
