Yr ateb y cytunwyd arno yw bod Lywodraeth y DU yn diwygio Rheoliadau Arwerthu Cynllun Masnachu Allyriadau Nwyon Tŷ Gwydr 2021 (y "Rheoliadau Arwerthu") trwy bŵer galluogi o dan Ddeddf Cyllid 2020, nes y gellir gwneud y newidiadau o dan Ddeddf 2008.
The solution agreed is for the UK Government to amend the Greenhouse Gas Emissions Trading Scheme Auctioning Regulations 2021 (the “Auctioning Regulations”) through an enabling power under the Finance Act 2020, until the changes can be made under the 2008 Act.
