Professor Barry McMullin:

First, they can do CCS. It is just more expensive. It is not a great location for CCS but they could do it. Second, as long as the price in the emissions trading system, ETS, remains low, which, relatively speaking, is still the case, the penalty for not following the ETS route, which is the only way of enforcing that penalty to make CCS happen in the current policy framework, it will not impact on them excessively.
