Thank you for that answer, Minister. Air pollution is a silent killer, contributing to almost 1,400 early deaths and costing the Welsh NHS millions every year. It's something that we must tackle urgently and I fully support the Welsh Government's commitment to a clean air Act. However, Asthma UK and the British Lung Foundation Wales are concerned that current proposals indicate that we might not see new regulations until the seventh Senedd term. While the White Paper sets out to improve air quality levels to be better than the World Health Organization recommended levels, what consideration has the Minister made to including regulating air pollutant levels during the progression of the Bill so that residents in some of the worst affected areas can gain the benefits as soon as possible?
