Essentially, whether or not a project proceeds is a matter for proponents, and that is an assessment that proponents make. In doing so they base their assessment on a range of factors including regulatory certainty but also, of course, finance and their assessment of the business case for the project at hand.

In the course of the debate, I have previously made reference to four projects that the government is aware of where there is a proposal to import carbon dioxide utilising the framework and the mechanisms, if they were available, that would be put in place under this bill. I've listed them previously. They are carbon capture and storage projects.
