The hon. Lady is absolutely right about the need to invest in cycling and walking infrastructure. Both of us, with many colleagues, participated in a debate in this Chamber on that very subject. The Government asked the Committee on Climate Change to consider what plans they need to put in place to enable us to reach that target; they are actively considering those plans and the Treasury is looking at the cost.
I have every confidence that the Government will produce detailed plans on how we are to reach the 2050 target, but I want them to set out clear milestones for the intervening period. Judging by conversations this morning with protestors, people think we will wait until 2050 to take any action, but we have already taken significant action, and the ambition is there to go further and faster. To give people hope and clarity, we need to set out the plans and milestones in detail so that people can see what is going on.
