The war between environmentalists and Prime Minister Tony Abbott's new conservative Government has begun in earnest.
Abbott has come under increasing fire for his plans to dump carbon pricing and an emissions trading scheme, axe an independent scientific commission on climate change, and hew through other climate bodies set up by the former Labor Administration.
He will face tough opposition in the Upper House, where the Greens will hold the balance of power until the new Senate convenes next July.
And his decision to jettison the Climate Commission - seen by opponents as an attempt to stifle debate - has prompted the former commissioners to continue as a new Climate Council funded by public donations. Abbott, who once called climate change science "absolute crap", has since accepted that human activity influences the Earth's climate but opposes carbon pricing and has pushed the issue well down his political agenda.
Government policy now embraces a range of measures, key among them a A$2.5 billion ($2.8 billion) plan to pay polluters to reduce greenhouse emissions. Abbott has kept Labor's target of cutting emissions by 5 per cent of 2000 levels by the end of the decade.
