South Australia stands to lose almost $3 billion of investment if Tony Abbott dumps the Renewable Energy Target, says SA Greens Senator Penny Wright.

New figures compiled by Senator Wright show South Australia will suffer more than any other state if the popular RET is scrapped.

“South Australia cannot afford to lose the RET,” Senator Wright said. “If the RET goes, $2.9 billion of investments in clean energy will go overseas instead.

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' National Council has this weekend determined to lead a vigorous and focussed campaign to ensure that Australia joins the rest of the world in securing a global treaty in 2015 and that big polluters are not allowed to impose the costs of global warming onto everyone else.

"Companies are now free to pollute in Tony Abbott's Australia, but not for long. The resurgence in support for pricing pollution and genuine action on global warming begins now," said Greens Leader Christine Milne.

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.

Questioning by the Australian Greens during Senate debate today has confirmed the Abbott government cannot guarantee families will be financially better off without a price on pollution.

"Not only will households have to deal with global warming, but the $550 they now think they're getting? Forget it. It's a mirage," said Greens Leader Christine Milne.

"In the Senate today, Finance Minister Cormann couldn't answer even the most basic questions about what the legislation will do. Either he doesn't know or he doesn't care.

Australian Greens Leader Christine Milne has today welcomed the Senate's agreement that members must be reappointed to the board of the Australian Renewable Energy Agency.

"After Clive Palmer excluded ARENA from his announcement, the Greens have worked with other crossbenchers to secure both the funding and the future of the organisation," said Senator Milne.
