I thank the hon. Lady for her comments and for the leadership she has shown on the Environmental Audit Committee. I will come on to how the independent Committee on Climate Change produced its response, but it set out clearly a range of scenarios involving a net zero transition and what action would be needed in industry, within society and among individuals to go from 80% to 100%.
We have set carbon budgets 1 to 5 to take us to 2032. Carbon budget 6, which will lead to 2037, will be set by June 2021 at the latest. It is important to recognise that we all have a role. Government especially have a role not only in legislating today, to ensure that we set the policy framework for achieving net zero, but in demonstrating each and every one of its Departments’ commitment to net zero. Her Majesty’s Treasury will conduct a review over the summer, as we move towards the spending review, of the impacts on business, society and across the public sector of the need to decarbonise swiftly and securely.
As part of that progress and the pathway towards net zero, we will be publishing an energy White Paper in the summer. A variety of different documents will be published, but I take the hon. Lady’s point; when it comes to the public sector, we will need to show leadership. We will need to be able to explain or change and to set out how all different areas of society will meet future carbon budgets—whether that is carbon budget 6, 7 or 8—on the road towards net zero.
