Ymhlith pethau eraill, trafodwyd y negodiadau diweddaraf rhwng y DU a’r UE ar y cytundeb masnach.  Gofynnais i Lywodraeth y DU ymrwymo i Gynllun Masnachu Allyriadau (ETS) wedi’i gysylltu ag ETS yr UE ac os na fyddai hynny’n bosibl, dadleuais yn gryf o blaid ETS annibynnol ar gyfer y DU. Byddai’n hynny’n well na Threth Allyriadau Carbon, sy’n bolisi a ddargedwir y mae Llywodraeth y DU yn mynd amdano yr un pryd ac sy’n bolisi na fyddai gan Weinidogion a Senedd Cymru unrhyw gyfrifoldeb amdano na dylanwad arno. Gofynnais am gadarnhad pryd y câi penderfyniad ei wneud a sut y byddai Llywodraeth Cymru’n cyfrannu at y penderfyniad hwnnw.  Ni chefais ateb gan Weinidog y DU i’r cwestiynau hyn ac ni cheisiodd chwaith â thawelu fy ofnau yn y cyfarfod.
The meeting included discussion of the latest UK-EU trade negotiations. I sought commitment from the UK Government to implement a UK Emissions Trading Scheme (ETS) linked to the EU ETS. If this is not possible, I made a strong case for a stand-alone UK ETS to be pursued in preference to a Carbon Emissions Tax, a reserved policy which the UK Government is pursuing in parallel and over which Welsh Ministers and the Senedd would have no responsibility or influence. I sought confirmation as to when this decision would be taken and how the Welsh Government would be involved in that decision. The UK Minister did not answer these questions or provide the reassurance I was seeking during the meeting.
