THE Australian Greens have secured a deputy chair position on a new parliamentary climate change committee, Prime Minister Julia Gillard announced.

The committee will receive independent advice from four experts - Ross Garnaut, Will Steffen, Rod Sims and Patricia Faulkner.

Ms Gillard will chair the committee while Climate Change Minister Greg Combet and Greens climate spokeswomen Christine Milne will serve as co-deputy chairs.

Ms Gillard said the committee would start from the position that a carbon price was required to reduce pollution and encourage investment in low-emission technologies.

Labor will invite two members of the coalition to sit on the committee. There will also be two Greens and representation from the independent MPs.

Independent Tony Windsor already has indicated his willingness to be a member of the committee.

"Parliamentary members of the committee will be drawn from those who are committed to tackling climate change and who acknowledge that effectively reducing carbon pollution by 2020 will require a carbon price," Ms Gillard said.

The multi-party committee will report to Cabinet through Mr Combet.

Its deliberations would be "broadly limited" to the issue of carbon pricing, Ms Gillard said.

The committee will consider mechanisms for introducing a carbon price, including a broad-based emissions trading scheme, carbon levy, or a hybrid of both.

Under the committee's terms of reference, decisions will be reached by consensus.

However, if no agreement can be reached, the decision will be put before Cabinet.
