Thank you, Deputy Presiding Officer. I'm delighted to move the motion tabled in the name of Darren Millar. During the debate today the Welsh Conservatives will demonstrate that not only does Wales currently have the worst air quality in the UK—a damning statistic in itself—but it's further compounded by the awful reality that 6 per cent of deaths annually in Wales are as a result of poor air quality and the impact that poor air quality has on asthma, lung conditions and heart and circulatory conditions. And this is why it's vital for the Assembly to prioritise bringing forward a clean air Bill before the end of the fifth assembly.

Breathing problems affect one in five of the population. Whilst charities and medical professionals are working hard to find new and innovative ways of treating and preventing respiratory diseases, they are fighting a battle against ever worsening air quality. A Public Health Wales report in 2014 estimated that over 13,500 life years were lost in Wales. What a tortured sentence that is. It's not actually people, but it's the amount of years that they could have lived if they hadn't had these awful diseases because of poor air quality. And 13,500 life years are an awful lot of life years. They also describe air pollution as second only to smoking as a public health priority. It is estimated that the cost to NHS Wales from health service costs and lost work days because of air pollution is over £1 billion per year. That's 11 per cent of the 2019-20 Welsh NHS budget.

An air pollutant is defined as any substance in the air that can harm people. Particulate matter and nitrogen dioxide are two pollutants. Particulate matter is a mix of solids and liquids, which includes carbon, sulphates, nitrates, mineral dust and water suspended in the air. The UK Government's air quality expert group states that half of particle pollution from road transport is made up from particles to do with brake wear, tyre and road surface degradation, which are enormous contributing factors. It is surprising that Wales has some of the worst air quality in the UK, considering our relatively low population density and our smaller cities. But, Cardiff and Port Talbot both have higher levels of some pollutants than Birmingham or Manchester, and part of Caerphilly is classed as the most polluted road in the UK outside of London.

This is down to us. The vast majority of air pollutants are man-made and the rising levels are a result of the choices that Governments and citizens make every day. We must accept our decisions—[Interruption.]
