First, I absolutely join the hon. Gentleman in celebrating Europe Day. European nations are our friends and neighbours and we have a strong and long-term relationship with them. He raises an important point about air pollution and is right to do so. I can tell him that air pollution has reduced significantly since 2010. Emissions of toxic nitrogen oxides have fallen by 29% and are at their lowest level since records began. Of course, we have to take action. We have put in place a £3.5 billion plan to reduce harmful emissions from road transport and, as he points out, we will end the sale of new conventional diesel and petrol cars and vans by 2040. Very importantly, we are implementing our new world-leading clean air strategy, and we will absolutely be tackling the very real concerns we all have about the quality of the air we are breathing.
