Australia will contribute $A200 million to a global fund to help poorer nations tackle climate change.
Foreign Minister Julie Bishop will announce the funding for the green climate fund at the UN climate summit in Lima today.
The money will come out of the foreign aid budget.
Prime Minister Tony Abbott said it was fair and reasonable for the government to pledge a contribution despite having ruled it out at the G20 summit in Brisbane.
"We've seen things develop over the last few months," he told reporters in Melbourne.
