Polluters 'should pay carbon tax'
The Australian government has proposed a carbon tax for its biggest industrial polluters from next year as a means of reducing the nation's greenhouse gas emissions.
The proposal to introduce a tax from July 1, 2012, has the support of the key Greens party and independent politicians but faces a battle in the Senate, where opposition parliamentarians argue polluters should remain free to emit carbon gas.
The most contentious details have not been decided in an outline of the proposal released by prime minister Julia Gillard.
Those include the price per ton of carbon tax and the amount of compensation that the government would pay to industry and householders.
