Australia has today joined New Zealand in imposing a price on carbon emissions across its economy in a bitterly contested reform that may cost the Prime Minister her job.
Australia's biggest polluters, from coal-fired power stations to smelters, will initially pay AUD$23 a tonne of carbon dioxide emitted.
That's more than twice the cost of carbon pollution in the European Union, which currently trades at about AUD$10 a tonne.
Prime Minister Julia Gillard says the plan is needed to fight climate change and curb greenhouse gas pollution.
But the opposition vowing to repeal it if they win power in elections due by late next year.
