New Zealand can do better in the fight against climate change than the international agreed goal, Prime Minister John Key says.
On Saturday, 196 countries reached a historic agreement to curb carbon emissions and restrict global warming to "well below" 2degC, with an aspirational goal of 1.5degC.
The outcome was "remarkable" and a "momentous occasion", Mr Key said.
"In New Zealand's case I actually think we're capable of doing more.
"We just need a bit of help from science and technology," he told the Paul Henry programme this morning.
The agreement is predicted to limit warming to around 2.7degC, but Mr Key said more needed to be done and technological advances would help.
"The world's not a static place - it's dynamic and I think that's why these countries can achieve more.
"The science certainly supports the need to achieve a lower level of increase than 2 degrees and 1.5 is probably more appropriate."
It's the first global climate deal and the first legally binding climate agreement since the Kyoto Protocol.
New Zealand's 2030 target is to reduce emissions to 30 percent below 2005 levels.
