As the hon. Lady will be aware, the Government have published a number of strategies that are kept under constant review. In my own area—business and industry—“The Road to Zero” was published about a year ago, and it talks about phasing out all petrol and diesel cars by 2040, which is something we need to keep under review. Many hon. Members on both sides of the House think we should do it faster and, as we roll out charging points, invest in industry and take various other steps, we should always keep these things under review as we seek to decarbonise transport, home heating and all sectors of our economy.
