The Australian Greens condemn the Turnbull Government for overseeing the censorship of a UN climate change report to remove all mention of the Great Barrier Reef and call on Minister Hunt to explain his role.

Qld Senator Larissa Waters, Australian Greens Deputy Leader and climate change spokesperson, said:

UNSW's world-leading research, announced today, which breaks a world record for solar efficiency, is funded through the Australian Renewable Energy Agency, which both the old parties want to cut by $1 billion.

Senator Larissa Waters, Australian Greens Deputy Leader and climate change spokesperson, called on Malcolm Turnbull and Bill Shorten to scrap their plans to gut ARENA's funding.

Confirmation from Cape Grim that atmospheric carbon dioxide has reached 400 parts per million and another poll showing Australians want action on global warming show the old parties are out of touch with the science and the community.

"Reaching this dangerous threshold of carbon pollution in the atmosphere, the highest in human existence, must act as a global wake-up call," Senator Larissa Waters, Australian Greens climate change spokesperson, said.

The Australian Greens are calling for the release of a Climate Change Authority report recommending a carbon price, which the Authority decided to delay until after the election - a decision the Minister's Office said made it 'very happy'.

The Liberals' budget fails the environment and the Great Barrier Reef, cuts billions from clean energy and tops up the billions in hand outs to the fossil fuel industry with another $100 million.

Qld Senator Larissa Waters, Australian Greens climate change and environment spokesperson, said:

"Our Reef is suffering record coral bleaching driven by global warming but the Liberals are ripping out a billion dollars from clean energy, and funding for work on Reef water quality comes from cutting Landcare.

The Liberal Government's budget fails to provide public transport or clean energy jobs in Queensland and instead focuses on military spending in other states.

"This budget is a let-down, especially for Queensland," Qld Senator Larissa Waters, Australian Greens Deputy Leader, said.

"While Sydney and Melbourne get billions for infrastructure, the Turnbull Government is denying Brisbane funding for the much-needed Cross River Rail because Queenslanders have voted against asset sales.

With Labor announcing a climate policy that seems to largely lock in the Abbott/Turnbull $1.3 billion cut from the Australian Renewable Energy Agency, the Greens are today submitting a Senate motion calling for ARENA's currently legislated funding to retained.

Senator Larissa Waters, Australian Greens climate change spokesperson, who will submit the motion today for a vote tomorrow, said:

"Labor's climate policy appears to lock in most of the Liberal Party's cuts to ARENA, leaving Australia with a $1 billion black hole in clean-energy funding.

The Environment Minister's announcement of $50 million in Reef Trust projects today is a re-announcement of existing Reef funding and is undermined by the Government's cut in 2014 of $40 million from a long-standing, water-quality program.  

Qld Senator Larissa Waters, Australian Greens Deputy Leader and climate change spokesperson, said:

"The Turnbull Government is desperately shuffling around existing Reef funding in an attempt to distract from its inadequate climate policies and continued coal mine approvals, which are cooking the Reef.

With Cabinet Ministers questioning climate science, the world will have little confidence in Greg Hunt's signature on the Paris climate agreement when he signs it in New York tonight.

"We have climate deniers running the country at a time when the world's chances of surviving global warming are at a tipping point," Senator Larissa Waters, Australian Greens Deputy Leader and climate change spokesperson, said.

The Australian Greens have joined with over 90 Greens parties around the world in committing to implement the Paris Agreement, reached at the UN climate summit, to stabilise global warming at 1.5°C above pre-industrial levels.
