Latest Air Quality in Bromley Data Shows No Need for ULEZ Expansion

Posted on by

The latest Air Quality Annual Status Report for the London Borough of Bromley which has just been published shows there is no justification for the expansion of the ULEZ scheme to outer London boroughs like Bromley.

To quote from a Council report: “There were no monitored exceedances of the annual or daily mean for Particulate Matter (PM10) in 2021. The annual average was 15.4μgm-3 . This is well below the national limit of 40μgm-3 .

The annual mean for Particulate Matter (PM2.5) concentration in 2021 was 9.7μgm-3 . This was also well below the national limit of 20μgm-3 .

Historically, the trend in Nitrogen Dioxide (NO2) concentration at the Harwood Avenue permanent continuous monitoring station, shows a decreasing trend. There was a slight increase from 2020 to 2021. This was due to life returning to normal following the changes to traffic levels during the COVID-19 pandemic and related lockdowns. The trends in NO2 concentrations for diffusion tube monitoring sites (for those with more than one year of data) for the 2015 – 2021 period also show evidence of a decreasing trend and all sites were below the national limit”.

In summary the measured pollution levels are well below national standards even on busy roads and the trend is downwards. There are unlikely to be any negative health impacts from the current levels of air pollution.

Manchester Campaign Against CAZ and Bromley Air Quality

While Mayor of London, Sadiq Khan, plans to expand his ULEZ scheme, in Manchester there has been a very effective campaign against their proposed CAZ scheme. Mayor Andy Burnham is now back-tracking on the proposals.

Daily charges for the most polluting vehicles that don’t meet emission standards – HGVs, buses, non-Greater Manchester licensed taxis and Private Hire Vehicles (PHVs) – had been due to begin on 30 May 2022 but will now not go ahead. The withdrawn legal direction would have led to charges for non-compliant vans, Greater Manchester-licensed taxis and private hire vehicles (PHVs) from June 2023. Private cars, motorcycles and mopeds were exempt. Concerns about financial hardship for local people and the availability of compliant vehicles led the Mayor of Greater Manchester and Greater Manchester local authority leaders to ask government to lift its legal direction. Greater Manchester’s 10 local authorities have until 1 July 2022 to work with government to develop a new plan that will clean up the air while protecting livelihoods.

The campaign against the Manchester CAZ has 90,000 supporters under the banner Rethink GM. Go here for more information: www.rethinkgm.co.uk and to register support.

Meanwhile the London Borough of Bromley have shown that it is not necessary to impose expensive ULEZ or CAZ schemes to clean up the air (most of that borough is outside the London ULEZ scheme). A press release from Bromley reports that updated data from the London Atmospheric Emissions Inventory shows that between 2016 and 2019 there was a 23% decline in NO2 across the borough, a 19% decline in PM2.5 and a 28% decline in PM10 particulates.

Bromley claims to now be the “cleanest and greenest borough in London”.

Comment: Bromley has of course ignored demands for LTNs and road closures and is keen to keep traffic moving. But they have pursued positive initiatives such as electric bus trials. Unlike many Labour controlled boroughs in London they have taken a more empirical and less dogmatic approach to the air quality issue.

Readers are reminded that the London ULEZ did little to contribute to improvements in air quality so why is the Mayor wanting to expand it? See https://freedomfordrivers.blog/2021/11/17/ulez-had-minimal-impact-on-air-pollution/ . It will cost a great deal to install hundreds of new cameras to expand the zone and high operating costs, apart from the impact on residents who will need to buy new vehicles or pay £12.50 per day. Although the Mayor says he has abandoned the idea of a boundary charge for people driving into London from outside, the extra cameras will make it very easy to introduce such a scheme!
