I commend that plan as a good example of the work that can be done to pull through change. We have increased our support for the transition to zero-emission vehicles across the country to more than £1.5 billion, which will fund charging points, some support for buyers, and the transition to clean mass public transport. I would welcome conversations both with the hon. Lady and with colleagues from other Departments. If we are to accelerate this process, we need to do that first in areas where it will make a real difference to air quality.
