Air pollution is responsible for 2,000 deaths per year in this country. It's a public health crisis, and it's your Labour Government's environmental legacy. That's why Plaid Cymru this week has launched a campaign, clean air week, and my colleague Simon Thomas yesterday launched a comprehensive report on hydrogen's role in the decarbonisation of transport. Now, I would urge the First Minister to read this expert-led, in-depth report and to take heed of its recommendations.

First Minister, this crisis warrants urgent action. Given that a road in Caerphilly is the most polluted outside of London, will you support our calls for a clean air Act for Wales that would phase out the sale of diesel and petrol-only vehicles by 2030?
