In an effort to combat air pollution and improve air quality, cities around the world are implementing Clean Air Initiatives. One such initiative is the Ultra Low Emission Zone (ULEZ) in London, which was introduced in April 2019.
The ULEZ in London sets strict emission standards for vehicles entering central London. It requires vehicles to meet Euro 6 emission standards for petrol cars, and Euro 4 for diesel cars. Vehicles that do not meet these standards are required to pay a daily charge to enter the zone. The aim of the ULEZ is to reduce harmful emissions from vehicles and improve air quality.
Since its implementation, the ULEZ has had a significant impact on air pollution in London. According to data from Transport for London, there has been a 44% reduction in roadside nitrogen dioxide (NO2) concentrations in the central zone, and a 20% reduction in nitrogen oxides (NOx) emissions from road transport in the whole ULEZ area. This has resulted in cleaner and healthier air for Londoners.
The ULEZ has also had positive implications for public health. Air pollution is a major health risk, contributing to respiratory diseases, heart conditions, and even premature death. By reducing air pollution, the ULEZ is helping to improve public health and save lives. Researchers estimate that the ULEZ could prevent approximately 300 premature deaths in the first year alone. However, the ULEZ does have implications for drivers and businesses.
