Of course, the huge leap forward under this Parliament, and one that this Budget will actually see, is the emissions trading scheme reforms, which James Shaw came and talked about in front of the select committee. At last, we have a cap-and-trade scheme with a cap, one where we can effectively price carbon. Carbon is not costless. If you look at coastal communities that are being inundated with flooding, they're the ones that are bearing the costs of carbon emissions elsewhere. It's only right that we now have a cap-and-trade scheme, an emissions trading scheme which correctly prices carbon, and that we have a sinking lid on carbon emissions where, finally, the genuine price of carbon will, in fact, be paid.
