The Australian Greens Leader, Senator Christine Milne, introduces a motion into the Senate to congratulate the United Nations Climate Summit and to recognise the 700 000 people who took part in the People's climate Marches across the world.

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"Under the carbon price that Tony Abbott repealed, Australia's emissions were falling faster and faster," says Greens Leader Christine Milne.

China's new coal import rules make it clear Australia is becoming a rust-bucket economy under the Abbott government, said Greens Leader Christine Milne.

"There's China moving to cut pollution while in Australia we have a policy vacuum and a Prime Minister who wants our economy to be reliant on exporting coal pollution to the world," said Senator Milne.

"Tony Abbott is putting his hands over his ears and refusing to hear the loud message that investing in coal, and building coal ports and railways, will lead to stranded assets and is jeopardising our future prosperity.

Australian Greens Leader Christine Milne says the Abbott government has today admitted it is undermining renewable energy to protect the old coal-fired generators, after comments by Industry Minister Ian Macfarlane on morning radio.

"The Industry Minister has belled the cat on the RET review. He's made it clear this attack on renewable energy is nothing more than a cynical move to prop up old coal-fired power stations," Senator Milne said.

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.
