Now, I would like to just start with the genesis of this legislation, just to remind the House where this has come from. As it happens, I was at the conference of the parties in Paris. I was in Opposition at the time. I was there as a guest of the then climate change Minister Tim Groser. He had started what is now a longstanding approach to bipartisan participation in the United Nations Framework Convention on Climate Change process. Of course, I have continued that in extending the invitations to the Opposition spokesperson to join us along on those, and unfortunately it's been somewhat ungraciously declined this year, which I think is a signal of the kind of backward steps that the National Party are taking when it comes to climate change, desperately trying to get themselves out of the bipartisan consensus that their predecessors were involved in starting.
