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.
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.
