The Climate Emergency

I thank the Secretary of State for giving way; she is making a powerful speech and being very generous with her time. Will she support my call that we introduce a net zero test so that we can ensure that at every fiscal event—Budgets and comprehensive spending reviews—we are investing to deliver, and perhaps we could get the Office for Budget Responsibility to scrutinise that so that everyone has confidence, as I do, that the Government are absolutely committed to delivering net zero?
