Claims, one by one

The text below is copied verbatim from the published record. Each claim names the source dossiers that carry it; caveats stay attached to the claim they qualify.

Claim 1 clm-25a20970ae225a6d descriptive
Greater Manchester's Clean Air Zone was to be a Category C charging zone across all ten boroughs of the city-region, including the City of Manchester
Published field
snippet · verbatim

What the mapping says
The combined authority's report names May 2022 and the vehicles affected (non-compliant HGVs, buses and non-GM-registered taxis and private hire vehicles); the trade press gives the scheduled start as 30 May.
Caveat
Vans and other light goods vehicles were to follow in a later phase; the first phase covered heavier vehicles and taxis.

Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
The government press release of 23 January 2025 says Defra and DfT concluded the investment-led plan will meet legal obligations, ruling out a zone, and lists funding for buses, traffic management and taxi upgrades; the combined authority's report records the acceptance of an investment-led, non-charging plan.

What the mapping says
The combined authority says the cameras helped develop the approved plan by showing TfGM the age and location of higher-polluting vehicles.

impact · verbatim
Mapping

What the mapping says
The committee report's table of Clean Air Plan exceedances (above 40.4 µg/m3) gives a total of 129 in 2019 and 11 in 2025, and for Manchester 65 and 9.
Caveat
The same table records 29 exceedances in 2018 and 16 in 2020, and the report does not give the number of sites monitored each year, so the counts are not a like-for-like series. Manchester's 2025 count includes the A34 Bridge Street continuous monitor, where nearby diffusion tubes no longer exceed.

What the mapping says
The report gives expenditure of £110.7m to the end of March 2026 and, in its budget table, £7.8m, £20.7m and £17.8m spent under Clean Air Zone development, implementation and operation.
Caveat
The programme's FAQ attaches the £110.7m to the Clean Air Zone service contract; the committee's table shows it is the whole plan's spending, including vehicle grants and the new investment-led measures.

What the mapping says
The NAO report says the pandemic's impact on supply chains, and its effect on the price and availability of second-hand vehicles, was a reason given for the February 2022 decision to let Greater Manchester delay.
Caveat
Press reports from the time also describe a public backlash against the charges and the size of the zone.

Newsletter briefing: the original plan would have charged non-compliant vehicles up to £60 a day; it was paused in February 2022 after intense public backlash against the charges and the region-wide size of the zone; the then environment secretary had said there was 'little robust evidence' that incentives would work; a mayoral candidate vowed to take down the cameras.
