The first is to, supposedly, use UK oil and gas as we transition to sustainability.
That, however, makes little sense when all the oil and gas produced will be traded in international markets, so at best, the aim of the exercise is to support the pound as we transition to sustainability, which is a lot more pragmatic and much less strategic, and considerably more uncertain as an outcome.
If it’s produced here then out government gets the mineral royalties. If it’s produced somewhere else then some other government does. But apparently the tax expert doesn’t know this.
