Rewrite this text; The Ultra Low Emission Zone (ULEZ) is a policy implemented in certain areas to reduce air pollution by charging vehicles that do not meet specific emission standards. To provide a summary of the main changes brought in by ULEZ, I will refer to the information from the BBC News article and the research briefing from the UK Parliament's Commons Library. According to the BBC News article, the ULEZ policy was introduced in London in April 2019 and expanded in October 2021. The main change brought by ULEZ is the requirement for vehicles entering the zone to meet strict emission standards. Petrol vehicles must meet Euro 4 standards, while diesel vehicles must meet Euro 6 standards. Non-compliant vehicles are subject to a daily charge. The ULEZ policy aims to improve air quality and reduce harmful emissions, particularly nitrogen dioxide and particulate matter. One potential benefit expected to arise from the introduction of ULEZ is the improvement in air quality. The Commons Library research briefing highlights that ULEZ has led to a significant reduction in nitrogen dioxide levels in central London. This benefit is related to both equity and efficiency concerns. From an equity perspective, improved air quality can have a positive impact on public health, benefiting all individuals, especially those vulnerable to respiratory issues. From an efficiency perspective, reduced air pollution can lead to lower healthcare costs and increased productivity due to improved overall health. However, there are also potential costs associated with the introduction of ULEZ. The BBC News article mentions that some critics argue that ULEZ disproportionately affects low-income individuals who may own older, non-compliant vehicles. This cost is related to equity concerns. The Commons Library research briefing further explains that the cost of upgrading vehicles to meet the emission standards can be a burden for individuals with limited financial resources. This highlights the potential equity implications of the ULEZ policy, as it may place a disproportionate burden on certain socio-economic groups. In summary, the main changes brought in by ULEZ include the requirement for vehicles to meet strict emission standards and the introduction of daily charges for non-compliant vehicles. One potential benefit of ULEZ is the improvement in air quality, which addresses both equity and efficiency concerns. However, there are also potential costs associated with the policy, particularly related to equity concerns, as it may disproportionately affect low-income individuals. It is important to consider both the benefits and costs when evaluating the impact of ULEZ.
