Air pollution in the United Kingdom has long been considered a significant health issue. Many areas, including major cities like London are found to be significantly and regularly above legal and recommended levels. Air pollution in the UK is a major cause of diseases such as asthma, lung disease, stroke, and heart disease, and is estimated to cause forty thousand premature deaths each year, which is about 8.3% of deaths, while costing around £40 billion each year.[1][2]
