The Federal Government has ratified the Paris climate agreement, amid concerns US President-elect Donald Trump will withdraw support for the agreement once in office.
Prime Minister Malcolm Turnbull told reporters Australia had ratified the agreement, which came into force earlier this month.
The agreement commits signatory countries to a pledge to limit global warming to two degrees and set five-yearly targets for cutting emissions.
“Almost a year from the Paris conference, it is clear the agreement was a watershed, a turning point and the adoption of a comprehensive strategy has galvanised the international community and spurred on global action," he said.
"We look forward to actively and fully implementing our obligations and our commitments under the agreement.
Trump has infamously said he'll withdraw America from the Paris agreement and stop funding UN climate change programmes – a move the Prime Minister has asserted Australia will not be following.
"When Australia makes a commitment to a global agreement, we follow through and that is exactly what we are doing," he said.
Foreign Minister Julie Bishop said the Government had determined that ratifying the Paris Agreement was in the country's national interests and would provide opportunities for Australian businesses.
"Australia joins 103 other countries at this point in ratifying the Paris Agreement. This accounts for over 70% of the world's emissions, over 75% of the global GDP and 85% of Australia's two-way trade," she said.
