New figures released today will deepen Australia's embarrassment at the UN Climate Summit, confirming the Abbott government has proudly dismantled a policy that was working to bring down pollution.

The latest Greenhouse Gas Inventory report shows nationwide emissions fell 1.1 per cent in the year to March 2014, smashing the previous record of -0.8 per cent, set in the year to December 2013.

"Under the carbon price that Tony Abbott repealed, Australia's emissions were falling faster and faster," says Greens Leader Christine Milne.

The Australian Greens say it's no surprise that a review led by a climate sceptic has trashed the Renewable Energy Target, saying both options the report presents will destroy renewable energy in Australia.

"I'm glad this dangerous and ignorant report is finally public, so everyone can see it for the climate denier drivel it is. The outcome was determined long ago," said Greens Leader Senator Christine Milne.

"It's now time to give the industry certainty by retaining and expanding the Renewable Energy Target.

Australian Greens Leader Christine Milne says a little-known creature native to tropical north Queensland should be recognised as a symbol of the serious and immediate threat to life presented by global warming.

A brooch modelled on the White Lemuroid Ringtail Possum has been unveiled today at the Association for Tropical Biology and Conservation (ATBC) conference at James Cook University in Cairns, to raise awareness of its plight.

The Australian Greens say the repeal of the price on pollution will be remembered as a monumental blunder in an era of dangerous climate change and a massive blow to Australian innovation, jobs and families. The Greens will now lead a campaign to restore genuine action on global warming.

"This is a tragic day for Australia and the planet but the Greens will lead the campaign to make the big polluters pay for global warming," Greens Leader Christine Milne said.

The Australian Greens say communities will lose out now, and in the future, if the Abbott government totally abandons the carbon price and mining tax.

"Tony Abbott will go down in history as the Prime Minister for the big end of town. He's shamelessly making life harder for everyday Australians to boost the profits of the big miners and big polluters," said Greens Leader Christine Milne.

The Australian Greens have called on the Palmer United Political Party to clarify their position on upcoming votes on the clean energy package and the Abbott Government's Direct Action proposal.

"Clive Palmer must not flip-flop on this. We need real action on climate change, not the joke that is the Abbott government's plan," said Australian Greens Leader Christine Milne.

"Direct Action means no action to stop the impacts of global warming on our communities and our environment, no-one voted for that.

The Australian Greens are calling to halt unconventional gas extraction right across the country after the contamination of groundwater from Santos' operation in north-western NSW.

"20 times the safe limit of uranium in the water there. That's a shocking finding that demonstrates the extreme danger to communities posed by coal seam gas extraction," said Greens Leader Christine Milne.

"The community has been told endlessly that there will be no contamination of aquifers, but now there is proof.
