New Zealand's Climate Change Minister James Shaw has ruled out his nation using carryover credits to count against its Paris climate target, saying such a move would make it challenging for the world to meet the important goal of reducing emissions.

Mr Shaw made the comments to Australasian journalists in a conference call on Tuesday after meeting his Australian counterpart Melissa Price during the climate talks in Katowice, Poland.

As the Herald has reported, Ms Price and her environment department have refused to exclude use of any surplus credit generated during the soon-to-be concluded Kyoto Protocol against Australia's Paris emissions pledges.

Federal Labor also said it won't rule out the use of Kyoto credits until it has received advice.
