The Prime Minister and cabinet have signed off on tomorrow's Green Paper which will take the country a step closer toward an emissions trading scheme.
The Green Paper will begin drawing the outlines of Australia's first emissions trading scheme.
Today cabinet met and approved the documents which have been framed with families, the environment and the economy in mind.
The Rudd government wants bipartisan support on emissions trading but in a curious twist the opposition has been excluded from tomorrow's media lock-up.
Opposition climate change spokesman Greg Hunt said the decision made a mockery of attempts to achieve bipartisanship on climate change.
Mr Hunt said the opposition's repeated requests to attend the lock-up had been ignored by the government.
"The Australian opposition has been locked out of the green paper lock-up."
"Our message is it makes a mockery of attempts for bipartisanship."
Climate change minister Penny Wong is making no apologies for the oversight.
"The Opposition on this issue has been all at sea."
Senator Wong said the government was sticking with its choice of a "cap and trade" ETS, and with its position that climate change was a serious issue which had to be tackled soon.
"We as a nation have a lot to lose from climate change, this is something we have to tackle for our current and for our future prosperity," Senator Wong said.
"This is a very important reform for the government, it's a very important reform for the nation and the future of the nation."
However Ms Wong now says the Opposition will be given a special briefing if it is required.
