"I would be extremely surprised if this is a repeat of a Copenhagen fiasco. Of course one can never say anything is too big to fail, so it's possible that it could fail, but i would be extremely surprised if that is the case, because we have a further evolution of political opinion since Copenhagen on climate change," Tim Groser said.
The Paris Climate Agreement should be legally binding just in some of its provisions, but not in defining how much states should contribute to emissions' reduction, Tim Groser said.
Paris Climate Agreement has been the aim of climate talks over the past six years. On Saturday, an updated text of the draft climate deal was released
"It's not about whether the actual deal has legally binding elements, but some bits of it are legally binding. In particular, where it becomes very controversial is the issue of the next set of commitments [of emission reductions]," Groser said.
According to the minister, issues arise with making the deal legally binding as the US Congress is likely to oppose it.
The Paris talks aim to reach a legally binding agreement that would replace the 1997 Kyoto Protocol, dealing with the reduction of greenhouse gas emissions. The participating countries submitted their goals for reducing emissions ahead of the conference.
