Asked by: Baroness Jones of Moulsecoomb (Green Party - Life peer)
Question to the Department for Business, Energy and Industrial Strategy:
To ask Her Majesty's Government what are their projections for additional greenhouse gas emissions arising from the thawing of the Arctic permafrost between now and 2100; and whether these projections have been taken into account in the COP26 negotiations on reducing national carbon budgets.
Answered by Lord Callanan - Parliamentary Under Secretary of State (Department for Energy Security and Net Zero)
The projections used by Her Majesty’s Government for additional greenhouse gas emissions arising from permafrost thaw between now and 2100 are those provided by the Intergovernmental Panel on Climate Change and amount to 76 [range of 14-177] gigatonne carbon dioxide equivalent per degree of warming globally, by 2100. These estimates were included in the Panel’s Sixth Assessment Report, which was officially welcomed by the UNFCCC at COP26, and taken into account in the negotiations.

Question to the Department for Business, Energy and Industrial Strategy:
To ask Her Majesty's Government whether their assessment of rising sea levels is based on a rise in average global temperatures, or includes modelling of Arctic and Antarctic ice melt taking into account the accelerated rise in regional temperatures at the poles.
Answered by Lord Callanan - Parliamentary Under Secretary of State (Department for Energy Security and Net Zero)
Our assessment of rising sea levels, derived from the Sixth Assessment Report of the Intergovernmental Panel on Climate Change, includes modelling of the Arctic and Antarctic ice melt and takes accelerated rise in regional temperatures at the poles into account.

Question to the Department for Business, Energy and Industrial Strategy:
To ask Her Majesty's Government whether their projections for additional greenhouse gas emissions from the thawing of the Arctic permafrost are based on a global rise in temperatures or a projected rise in the temperature of the Arctic region.
Answered by Lord Callanan - Parliamentary Under Secretary of State (Department for Energy Security and Net Zero)
The projections of additional greenhouse gas emissions from the thawing of the Arctic permafrost that are used to inform government policy are taken from the Intergovernmental Panel on Climate Change Sixth Assessment Report and take Arctic regional warming rates, including effects such as polar amplification, into account.
