Diolch, Llywydd. Improving air quality is a key priority in the Welsh Government's national strategy, 'Prosperity for All', and it is likewise a key portfolio priority for me. Taking steps to improve our air quality contributes significantly to the majority of the well-being goals in our future generations legislation and I'm firmly committed to taking forward action in this area. The need for urgent action is not just about compliance with the law, it's essential and the right thing to do for the health and well-being of our people and communities. There is not one single solution to the challenge, but there is a collective responsibility on all of us and a role for Government across the piece—local, UK and here in Wales. I hope to use today's debate to take forward the discussion on the cross-Government actions needed to improve the quality of our air in Wales.
