According to Public Health England, air pollution is the biggest environmental threat to health in the UK, with between 28,000 and 36,000 deaths a year attributed to long-term exposure.

There is strong evidence that air pollution causes the development of coronary heart disease, stroke, respiratory disease and lung cancer, and exacerbates asthma.

The UK government has spent the past few years locked in a legal wrangle with environmental law firm ClientEarth, accused of not acting swiftly enough to tackle poor air quality.

As a result of ClientEarth’s success in the courtroom, the government has been forced to produce two new air quality strategies to tackle illegal breaches of nitrogen oxides (NOx) in urban areas.

This has seen a series of mandates rolled out to more than 60 local authorities in England to either submit clean air zone (CAZ) plans, or carry out feasibility studies to assess if one may be needed to tackle pollution hotspots.

Alongside this, both the Welsh Assembly and Scottish Government have been working on their own emissions-reduction policies for affected cities.

The Scottish government has tasked its four major cities: Aberdeen, Dundee, Edinburgh and Glasgow to implement Low Emission Zones (LEZ) by 2020 and into other air pollution hotspots by 2023.

The Welsh government has instructed Cardiff and Caerphilly councils to explore CAZ potential as part of its wider air quality strategy.

 

So what is a clean air zone?

According to the government’s definition, a CAZ is an area “where targeted action is taken to improve air quality and resources co-ordinated in order to shape the urban environment in a way that delivers improved health benefits and supports economic growth”.

Each CAZ will be expected to fulfil a number of minimum requirements before being approved, such as establishing a clearly defined air-quality issue; supporting uptake of ultra-low- emission vehicles (ULEVs); and local authority leadership through own fleet use of ULEVs and procurement standards to support the zone.

CAZs can take the form of a non-charging geographic area that includes a series of air quality improvement measures and incentives, or the more widely-known charging model, where vehicles must meet an emissions standard or pay a fee to enter.

They are categorised according to the vehicles brought into scope in each plan  (see below).

All CAZs would require a minimum of Euro-4 petrol or Euro-6 diesel vehicles

  • Class A: Bus, coach, taxi and private hire
  • Class B: Bus, coach, HGV, taxi and private hire
  • Class C: Bus, coach, HGV, large vans, minibus, small vans, taxi and private hire
  • Class D: Bus, coach, HGV, large vans, minibus, small vans, cars, taxis, private hire, motorcycles and mopeds (optional Euro-3)

 

What is happening in each city?

Since the government issued its mandate to local authorities to improve air quality, they have been measuring pollution levels, identifying hotspots and taking steps to reduce emissions.

For some, legal levels have already been brought under control or they are on track to achieve targets within the required timeframe; for others, full-scale CAZ plans have been developed.

Motor Transport has compiled a list of those councils instructed to assess their air pollution levels, with handy links to relevant local authority pages.

Please bear in mind that many councils’ timelines are currently disrupted by the covid-19 pandemic, so make sure to click through to their sites for the latest updates.
