Thank you for that answer, Cabinet Secretary. The A472 in Crumlin: according to Government data, the levels of nitrogen dioxide here are the highest recorded in the UK outside London. The levels are exceeded in England only by a similar monitor on Marylebone Road in central London, and according to Asthma UK Cymru, 314,000 people have asthma in Wales, including 59,000 children: almost one child in 10. A report from NHS Wales and the Welsh Government, published in 2015, said the percentage of patients registered with their GP for asthma and COPD, chronic obstructive pulmonary disease, was greater than in England, and there had been a slight increase in recent years. What urgent action can the Welsh Government take to work with Caerphilly County Borough Council and other stakeholders to lift the scourge of air pollution?
