The Government has stopped even pretending it is serious about combating climate change, the Green Party says.
A bill introduced to Parliament on Thursday will implement previously announced changes to the emissions trading scheme (ETS) and the Greens say it is a "self-defeatist piece of legislation".
The bill indefinitely defers bringing agriculture under the ETS and freezes the price the scheme puts on carbon emissions.
The Government says it can't afford to impose burdens on the economy during tight financial times.
"This is business as usual for the government - they don't want to deal with climate change and so, just as with the brain drain to Australia, unemployment and housing unaffordability, they are simply ignoring it," the Greens' climate change spokesman Kennedy Graham said on Thursday.
"The ETS was already weak but will be irrelevant after these changes go through."
Dr Graham says the effect of the bill means taxpayers will have to keep subsidising polluters as the Government meets its international climate change obligations.
