If the revenue is shared, is it going to be shared on a population basis? Is it going to be Barnettised? Is it going to reflect the fact that 9 per cent of the installations subject to the scheme are based in Wales, or that 15 per cent, I think, of the UK emissions within the scheme come from Wales? ETS participants account for 46 per cent of total Welsh emissions and 30 per cent of UK emissions. So, without answers to these questions, there is a risk that we will disproportionately lose out here in Wales.

Now, a UK ETS scheme linked to an EU ETS scheme is the right way forward, but I share many of the concerns, particularly the concerns expressed by the Chair of the climate change committee, around the level of ambition here, especially in relation to the emissions cap and the scope of the scheme. The UK Committee on Climate Change, as we've heard, tells us that the proposals are inconsistent with our net zero ambitions. Yet, here we are today, ploughing on regardless, waving this through, potentially, during climate week, of all weeks—how ironic is that?

Now, I appreciate that not all of this is the Welsh Government's fault; it's more a reflection of the shambolic way that the UK Government is handling its preparations for the end of the transition period. But this is being rushed through. It is being brought before us in a piecemeal manner. And, of course, as we've heard, there's a very strong likelihood that there won't be an emission trading scheme anyway, because the UK Government is now suggesting that their preferred option is a carbon emissions tax. So, all of this could be redundant in a matter of weeks. And, you know, whilst we support the principle of a linked ETS, this really represents everything that's wrong about the process, on an inter-governmental level, certainly, but on a Senedd level as well. It's not ideal; this is a 15-minute debate, and, of course, it's been brought forward before the climate change committee has had the opportunity to consider and complete its deliberations on the matter. So, it's frustrating, and I'm afraid that Plaid Cymru will have no choice but to abstain.
