International media singled out Australia's insistence it be allowed to count"over-achievement"during the 2012-20 Kyoto Protocol period to reduce its abatement task during the 2021-30 Paris accord as one brake on progress.
Sweden's TT News Agencyblamed the stalled talks on Australia,Saudi Arabia and Brazil.
John Connor,chief executive of the Carbon Markets Institute,said a ban on Australia's use of so-called Kyoto carry-over credits remained an option in final drafts.
The use of a"surplus"– effectively halving Australia's Paris pledge of reducing 2005-levels of emissions by 26 per cent by 2030 – opened the door to India and former Soviet nations to cut their ambition too,he said.
"Other countries definitely care ... because the Kyoto carryover is a card only developed countries,who had carbon budget commitments under the Kyoto protocol,can play,"Mr Connor said."To date it remains that only Australia is willing to play that card and it’s not winning them friends."
The Carbon Markets Institute said 76 per cent of Australian businesses are opposed to the Morrison government's plan to use Kyoto credits to cut the Paris abatement task,citing survey results it will release on Monday.
