Federal Opposition Leader Bill Shorten says Labor will be sticking to its position that action on climate change must be taken sooner rather than later.
But Mr Shorten wouldn't speculate on the prospect of a double dissolution election if Labor and the Greens combined in the Senate to thwart the government's plans to repeal the carbon tax.
"We have yet to see the extended debate about what it all means and the detail of the government's legislation," the leader told reporters in Canberra on Friday.
"I will work with our team and I will take the advice of our team."
Labor's fundamental principle was that climate change was real, carbon pollution contributed to global warming and that there should be a price on carbon emissions.
"There's a lot of detail to wait and see but that is our basic principled position which we will be sticking to," he said.
"We don't change our views. We are not a weather vane on climate change. In terms of our specific policies, we will work on them in the lead up to the next election."
Mr Shorten said the government's Direct Action policy was a "clunker", which would impose a $1300 tax on every household and fail to reduce emissions in line with government targets.
"The government must be the only people in political history who tell you they are decreasing the cost on households by putting more costs on households. It doesn't add up," he said.
He noted Labor's pre-election promise to move from a fixed carbon price to a floating one under an emissions trading scheme in mid-2014.
