We need to get those targets right. In the Environment Bill, which should be back in this place shortly, we have committed to setting a target, but it is important that we get the evidence right to set the right targets. Those targets will be based on evidence. We are currently reviewing the air quality strategy. We will be looking at a revised strategy in 2023. The PM2 target is on a population basis. We also need the population exposure targets so that in areas such as hers, where we know that there are hotter spots, we can work directly with local authorities—we all own this challenge—to get the right targeted measure in the right areas. The overall target is important, but so are those targeted, individual approaches.
