Australian Greens Leader Christine Milne has commended the leaders of the European Union for today setting an emissions reduction target of 40 per cent by 2030, saying Australia's 2020 target is disastrously inadequate and must be drastically increased for 2030.

"For the health of our communities and the health of our economy, Tony Abbott needs to pull his head out of the sand and get real about action on climate change," said Senator Milne.

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"Under the carbon price that Tony Abbott repealed, Australia's emissions were falling faster and faster," says Greens Leader Christine Milne.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 Australian business have an opportunity to help end the global warming policy farce and avoid Mr Palmer's yellow tape by supporting emissions trading.

"The Abbott government is incompetent, incapable of negotiating with the Senate, and so bloody-minded that they've agreed to push through an amended law without any consultation or any understanding of what those amendments will do," Greens Leader Christine Milne said.

"What sort of government gets so desperate that it says it will support a law without understanding what it means?

Responding to President Obama's new and more ambitious climate policy, the Greens say Australia is being leapfrogged by the US when it comes to taking action to reduce carbon pollution, because of Tony Abbott's last century and anti-science policy to abolish the price on pollution.

"President Obama has shown up the Prime Minister as completely out of step on global warming. Barrack is moving forward but Tony is stuck in reverse," Greens Leader Christine Milne said.

The Australian Greens are accusing the Abbott government of selective hearing, as the new National Greenhouse Accounts out today show emissions are continuing to drop.

"The data is up on the Environment Department website but you won't hear about it from the Minister, because the figures don't fit with the Abbott government's rhetoric," said Greens Leader Christine Milne.

"Every one of these quarterly reports has seen emissions drop in areas covered by the carbon price, since it kicked in on July 1, 2012. In this latest report, energy emissions are down 5 per cent.

"Prime Minister Rudd has to stop pretending that former Prime Minister Gillard didn't achieve an Emissions Trading Scheme," Australian Greens Leader Senator Christine Milne said.

"She did what he couldn't do.

"Julia Gillard negotiated with the Greens and got a great result.

"Rudd negotiated with the Coalition and failed.

"I would be delighted to debate Mr Rudd at the Press Club on climate change."
