They've pulled out of Kyoto.
Moana Mackey describes National's disgraceful action best:
"“This is a day of shame for New Zealand, our reputation as a good international citizen has taken a massive hit. To pull out of Kyoto the same day that Australia committed is humiliating. Australia’s position used to be essential to Government policy when it suited National. But now that Australia is tackling the critical issue of climate change, National is silent. National doesn’t take climate change seriously. It has gutted the emissions trading scheme and has now withdrawn from Kyoto commitments."
