Environmental Audit Committee Inquiry on parliament.uk ↗
Inquiry scope (the committee's words)
The Environmental Audit Committee is examining the role of HM Treasury in shaping the UK’s response to climate change, nature loss and wider environmental sustainability. The Government’s economic policy objective includes a commitment to “accelerate the transition to a climate resilient, nature positive and net zero economy”. [1] This inquiry will explore how HM Treasury influences the Government’s approach to climate change, nature loss and environmental sustainability through economic policy, appraisal frameworks and funding decisions. It will also assess the extent to which these objectives are reflected in practice, including whether climate, nature and environmental sustainability are recognised as contributors to long term growth and resilience. In addition, the inquiry will consider how effectively climate and environment related risks and opportunities are assessed within economic and fiscal decisions, and what impact HM Treasury has in addressing them. [1] Remit for the Monetary Policy Committee Read the call for evidence for more information about this inquiry, and to find out how to submit written evidence through the Committee's online evidence submission portal.
