Prime Minister John Key is preparing to leave for Denmark on Tuesday where he will join Climate Change Minister Nick Smith at the Copenhagen climate conference.
Smith is among dozens of environment ministers arriving in Copenhagen on Monday as the United Nations summit gears up for a second week of talks.
But analysts have reported little progress in replacing the
current treaty, the Kyoto Protocol, which expires in 2012.
Documents prepared so far call on developed nations to cut
greenhouse gas emissions by between 25% and 45% of 1990 levels by
2020.
One Hundred and fifteen world leaders, including Key, are due to sign an accord to tackle global warming on Friday.
Meanwhile, the Green Party is attacking the government's record on climate change.
Greens co-leader Metiria Turei says Solid Energy's coal production is going up at the same time the government is claiming it can do nothing to reduce carbon emissions.
She is also scathing that national air quality standards are under review, meaning moves to phase out the use of coal fires in homes may be delayed.
