As concerns grow that US president-elect Donald Trump could withdraw the US from the Paris climate deal, Australia has ratified its greenhouse gas emission targets. Trump previously said global warming is a "hoax."
"Ratification of the agreement confirms Australia's ambitious and responsible target to reduce emissions by 26 to 28 percent below 2005 levels by 2030," Prime Minister Malcolm Turnbull said in a joint statement with the two ministers.
With its relatively small population of 24 million and continued heavy use of coal-based energy, Australia is considered one of the world's worst per capita greenhouse gas polluters.
The US is among the 140 countries to have already ratified the agreement which account for 70 percent of the world's emissions and three-quarters of global GDP.
Prior to his election on Wednesday, Trump called global warming a "hoax," raising concerns among environmentalists and climate scientists that the US would once again pull out of an international climate deal.
The US currently produces 13 percent of global emissions, making it the world's second-largest greenhouse gas polluter after China.
France's environment minister and outgoing head of the UN climate forum Segolene Royal said on Wednesday, however, that Trump "cannot prevent the implementation" of the pact.
"He cannot - contrary to his assertions - undo the Paris Agreement," she told French radio station RTL.
UN climate change talks are currently underway in Morocco where the Paris agreement is due to be discussed next week.
