Premier Colin Barnett says it's not too late for the Federal Government to halve its carbon price "to something around $10 a tonne", even though he does not believe it will reduce greenhouse gases.
While the outspoken Liberal Premier said he was opposed to any carbon price, he said Prime Minister Julia Gillard should at least reduce its impact.
"To bring in a carbon tax at $23 a tonne, when the market price in Europe is about $7 a tonne, is just crazy," Mr Barnett said.
"The sensible thing that Julia Gillard should have done, at a minimum, (is) just halve the rate."
Even if the government did cut its carbon price in line with other nations, Mr Barnett said it would do little to reduce emissions.
"We have a capacity in Australia to dramatically reduce greenhouse gas emissions by simply using more gas in power generation and less coal," he said.
"But I think it's very evident the introduction of this carbon tax is not going to see some of the dirtier coal power stations close down.
"The federal government is actually giving them subsidies to continue."
The premier said it was probably a moot point anyway, as Mr Abbott would remove any carbon pricing mechanism if he wins power.
"If there's a change of government, the carbon tax will be gone," Mr Barnett said.
The premier claimed most people in WA would be worse off under the new polluter-pays regime, saying it would add "a nine per cent tax on every electricity bill for householders and businesses" in the state.
He also claimed WA would also be hit hard by the new minerals resource rent tax that comes into effect on Sunday.
"Imposing a carbon tax on every employer, every industry, every consumer and then putting a heavy mining tax onto the successful states of Western Australia and Queensland just means you're going to see a lot more jobs lost in this country over the next 12 months."
