I agree with you entirely. I also come from the business community, so I understand the importance of certainty with respect to business investment. Certainly it has been very clear, and this government has been very clear and most other parties in Parliament have been very clear that there is a need for enhanced ambition. That's not new. That's something that people have been talking about for years. It is in line with science and what science tells us we must do, so there's no big surprise here.
However, what I would say is that they do require certainty with respect to major policy instruments. That's why I was very pleased a few weeks ago to see the Conservative Party actually endorse a carbon tax and a clean fuel standard, two policies they have been fighting for the past number of years and things that are really important in terms of having certainty. Therefore, I welcome the Conservative Party actually coming to the party.
