Australia is moving "towards a new energy future", powered by unprecedented investments in renewable energy, Environment Minister Melissa Price has told a summit in Poland even as the country earned a "fossil of the day award for its poor climate policies.

In a speech on Wednesday at the COP24 climate talks in Katowice, Ms Price said Australia was "committed to the Paris Agreement" and the development of a "robust rulebook" to implement the global pact agreed in 2015.

"The clear message from the dialogue is that we must act, and act together, because climate change affects us all, and Australia must play its part," Ms Price said.

"Our clean energy finance corporation, the world’s largest green bank, has leveraged nearly $20 billion in low-emissions technology investment," she said, adding that Australia would also help "fuel the battery storage revolution" with its large reserves of lithium.
