I'm somewhat less enthusiastic about CCUS, because we have not seen a demonstration of anything approaching the scale that would be required to make a difference on the climate side. Cost remains a big problem. There are questions about effectiveness and how sequestered things really are.
Then the other big problem is the question of geology. You can't do this in large parts of the country. If you were going to do CCUS in Alberta, it's probably relatively well suited. In somewhere like Ontario or Quebec, geological candidates are, to put it mildly, rather more limited. Those are factors. I'm concerned that we have an awful lot of eggs in the CCUS basket at the moment.
