I think you can do a number of things. You have the carbon pricing regime, which you can apply at the border and you could apply to exports. You could use the clean fuel standard to impose a greater demand on the oil and gas sector, if that's what you want, on sectors of the oil and gas sector.
You have all the mechanisms in hand already to drive whatever outcomes you want to see and, of course, the tax code policies that you've already talked about in the previous budget, on carbon capture and storage, are an option. You have energy policies, so you have the tools in your tool kit. We don't need to start talking about and developing a new tool.
