Question to the Department for Business, Energy and Industrial Strategy:

To ask His Majesty's Government, further to the Written Answer by Lord Callanan on 16 December (HL3971), what assessment they have made of the cost to the UK of following the advice of (1) the IPCC, and (2) the World Climate Declaration; and over what period of time they will take advice from both organisations.

The IPCC assesses the latest and most policy-relevant climate science, but does not make specific policy recommendations or directly advise governments. The IPCC's assessments are used on an ongoing basis to inform government decision making, including the UK Net Zero Strategy. The Government has not made an assessment of the World Climate Declaration.
