Q In our previous session, we had an interesting and thoughtful discussion with witnesses about how the planning system might help us to respond to the climate and environment emergency. I will finish with a question that I asked in our second session. You will know that nowhere in legislation is the purpose of the planning system set down. Do you think there is any value in more clearly defining in legislation the aims of the planning system on climate change and other issues? Is the Bill an opportunity do to that, and if so, what would that look like?
