I do think it's worth just tracking back a little bit to the why—why it is we are moving forward with this policy. It goes back to the fact that we have this enormous challenge in front of us, one that this entire House, virtually, has accepted: the challenge of actually taking decisive action on climate change. We know that we have to take up that challenge if we want to reach net zero by 2050 and, barring one party currently in this House, every party represented here, including the National Party, voted to try and reach net zero by 2050, voted to set up an independent climate commission, and voted to set up five-yearly carbon budgets to ratchet down our emissions to reach those targets. Well, having done that, we can't just sit on our fine words as a House; we actually have to introduce the policies that will make the difference, and that is a challenge for every party in this House as they come to vote on this piece of legislation tonight.
