Australia’s new government has backed a crucial a push for developed countries to make deep cuts to their greenhouse gas emissions by 2020, a report said on Thursday.

Canberra’s representatives at key climate talks in Bali said Canberra now fully backs a proposal for the nations to cut emissions by up to 40 percent in the next 12 years, the Sydney Morning Herald said.

Australia’s new Prime Minister Kevin Rudd ratified the Kyoto Protocol on climate change as his first act in office on Monday, but did not state his position on getting developed countries to set emissions cuts targets.
