Clive Palmer has announced that his Palmer United party (PUP) senators will vote to repeal the carbon tax if savings are passed on to the average Australian, and will support an emissions trading scheme (ETS).

In a joint press conference with former US presidential candidate Al Gore, Palmer said his party would move to amend the repeal legislation to force producers to pass on savings to consumers.

Palmer said his party would move an amendment for an ETS – a floating price on carbon – and would also vote to retain the Climate Change Authority.

He said the party would not support a change to the Renewable Energy Target until after the 2016 election.
