Shaw JamesJAMES SHAW (Co-Leader—Green): I rise to advise the House that the report from Vivid Economics on New Zealand's emissions mitigation potential has been completed and was released publicly yesterday. The report is entitled Net Zero in New Zealand: Scenarios to achieve domestic emissions neutrality in the second half of the century. It was commissioned by GLOBE New Zealand a cross-party group of 35 MPs—one in four MPs in this House—drawn from every single political party represented. The group is chaired by my colleague Dr Kennedy Graham and has an executive committee composed of the Hon Peter Dunne Marama Fox Tracey Martin Scott Simpson and Dr Megan Woods.In my first speech as co-leader of the Green Party of Aotearoa New Zealand I said that our climate cannot wait while politicians squabble over how to fix it. Let us build common cause on climate change. We should talk to each other rather than past each other and agree on an ambitious target that New Zealanders can be proud of. New Zealanders want their politicians to work together and act on common interest. Let us find common interest on climate change. That was my challenge to John Key back in the middle of 2014.The debate has moved on. It is hard to imagine that only about 10 years ago a National Party MP was driving a tractor up the steps of Parliament to protest the idea that you would put a price on carbon pollution. There are four stages of the debate that countries pass through. The first is whether or not climate change is actually happening—people say it is not happening. The second stage is to say: Well if it is happening it's not us. It's not humans." The third stage is to say: "Well if it is us it's actually not that bad." The final stage is to say: "Well if it is that bad there's nothing we can do about it." Those are the four stages of climate denialism that we have been passing through over the course of the last 25 years in this country. Of course the antidote to those is that it is happening that it is us that it is bad and that we can do something about it. The report that was released yesterday shows that the debate has finally finally finally moved through all three of those first stages to the final stage of what we can do about it.I would like to take a moment just to talk about the sort of non-partisan nature of the report and of the committee that has pulled it together. The Hon Paula Bennett in her speech at the launch yesterday said that Dr Kennedy Graham was a dog with a bone. I really want to acknowledge his leadership and his tenacity in pulling together that group of people—that committee of 35 members of Parliament who are concerned about climate change—and in commissioning what has been a very significant report.I would also like to acknowledge the Hon Paula Bennett because I have to say that without her acquiescence at the very least it would not have been possible for National MPs to safely participate in that group. In fact it was not until after she became the Minister that National MPs could join the GLOBE group. I recognised the political difficulty—the risk that some members of the House have had to take in order to be able to participate in a non-partisan cross-party parliamentary group on climate change. So I want to acknowledge her leadership in that role and in particular Scott Simpson who has really led the National MPs on that committee in order to make it a truly cross-party cross-Parliament committee. I also would like to acknowledge Vivid Economics and all of the officials businesses and NGOs that contributed to the report because it is a substantial and substantive piece of work.For half my life—more than half my entire life—we have been debating climate change. There have been reports and reports and reports and targets that have been met but New Zealand's emissions have relentlessly climbed for decades and they are still climbing. It is now time for us to move to action and urgent action if we are to prevent dangerous climate change. I welcome this report. It gives us an opportunity to debate what we do about it and the time for that action is now."
