So, we've got so many leases up there for gas projects to go ahead, and at the moment a lot of gas projects are going ahead and can be taken up at any time. Under this legislation, will they be forced or told they must take up carbon capture or storage? How does it work? Just tell me how they counteract their carbon emissions that they are releasing at the moment? How are you dealing with the North West Shelf and what they're doing up there?
