Greens Leader Bob Brown says his five-point plan is the best way to break the stalemate on climate action, after Labor twice failed to get its carbon pollution reduction scheme through the Senate.
The Greens want a $23 per tonne price on carbon to be in place by July 2011, based on the work of government adviser Professor Ross Garnaut.

Ms Gillard's options would be left open for a future emissions trading scheme and emissions reductions targets, Senator Brown told ABC Radio on Tuesday.
"She cited getting a carbon price in her first speech on Thursday as one of her priorities," he said.
"She knows like all of us do that quick action on climate change is wanted."
Under ousted prime minister Kevin Rudd, the government was marked down by voters because it backed away from an election promise to take action on climate change, Senator Brown said.
He revealed Ms Gillard had contacted him on the weekend to flag her announcement to change the population portfolio to "sustainable population", and he looked forward to meeting with her in person soon.
