Poor air quality is one of the biggest environmental and public health challenges of our time. The UK government has recognized the urgency of addressing this issue and has implemented several strategies to reduce air pollution, including the creation of Clean Air Zones.
What Are Clean Air Zones?
Clean Air Zones, or CAZs, are areas designated by local authorities in the UK that aim to reduce pollution levels by discouraging or restricting the use of high-emission vehicles. These zones are typically located in urban areas with high traffic volumes and poor air quality. The main goal of Clean Air Zones is to reduce levels of nitrogen dioxide and particulate matter, which are the most harmful pollutants to human health.
There are currently four types of Clean Air Zones in the UK, each with its own set of requirements and restrictions:
- Class A – charges are levied on non-compliant buses, coaches, and HGVs.
- Class B – charges are levied on non-compliant taxis, private hire vehicles, and light goods vehicles.
- Class C – charges are levied on all non-compliant vehicles, including private cars.
- Class D – charges are levied on the heaviest-polluting vehicles, such as lorries, buses, and coaches, that enter a specific area.
Why Exactly Do We Need Them?
The World Health Organisation (WHO) has classified air pollution as the largest environmental health risk and linked it to heart disease, respiratory disease, and cancer. Air pollution affects our most vulnerable populations, including children, the elderly, and those with pre-existing health conditions. The cost of air pollution in the UK is estimated to be around £20 billion yearly.
The transport sector is a significant contributor to air pollution in the UK, with diesel vehicles being the largest source of NOx in urban areas. A study conducted by the Royal College of Physicians and the Royal College of Paediatrics and Child Health estimated that air pollution caused by diesel emissions could account for around 40,000 premature deaths in the UK. In recent times, prominent automakers have found themselves caught in diesel emission scandals. Volkswagen has incurred substantial fines as compensation for customers, while another automaker has confessed to falsely reporting Nissan emission levels. Clean Air Zones are necessary because they provide a concrete solution to reduce air pollution levels while promoting sustainability.
How Do Clean Air Zones Work?
Clean Air Zones work by discouraging or restricting the use of high-emission vehicles within their designated boundaries. This is typically achieved through the implementation of a range of measures, such as charges, fines, and low-emission zones.
To assess which vehicles are compliant with the Clean Air Zone regulations, vehicles must meet specific emissions standards. These standards are set by the European Union and adopted by the UK government. Vehicles that meet these standards are classified as Euro 6 for diesel vehicles and Euro 4 for petrol vehicles.
Non-compliant vehicles are subject to daily charges or fines, which can vary depending on the type of CAZ and the level of non-compliance. In some cases, drivers are given a grace period of several months before the charges are enforced.
What Benefits Do Clean Air Zones Offer?
The benefits of Clean Air Zones include a reduction in exposure to harmful pollutants and an improvement in health. A study found that exposure to NO2 pollution was linked to deaths from heart disease. Implementing CAZs would, therefore, reduce exposure to NO2 and, in turn, reduce the risk of heart disease.
Reducing air pollution also has economic benefits. A report by the UK100, an alliance of local government leaders, found that the introduction of Clean Air Zones has the potential to deliver £13.7 billion in economic benefits to the UK, mostly from healthcare savings and increased productivity due to fewer sick days.
Implementing Clean Air Zones in urban areas can also reduce congestion, encourage active travel, and promote sustainable development. This, in turn, can help transform the urban environment into a cleaner, greener, and more liveable space, benefiting both citizens and the environment.
What Challenges Do Clean Air Zones Face?
While Clean Air Zones offer many benefits, they also face several challenges and criticisms. One of the main challenges is the cost of implementation, which can be high due to the need to install new infrastructure and enforce compliance. This can be especially challenging for smaller local authorities with limited resources.
In addition, Clean Air Zones can also face opposition from businesses and residents who are concerned about the impact of charges and restrictions on their operations and daily lives. This can result in pushback against the implementation of the zones and the need for difficult conversations between local authorities and stakeholders.
