Whatever they’ve agreed to - for the moment - the Greens, and key independents Rob Oakeshott and Tony Windsor, all want petrol included in a carbon tax.

The Greens policy says they want all sectors and all major sources of emissions covered by a carbon price.

Rob Oakeshott voted three times for a carbon tax on petrol when he voted three times for Kevin Rudd’s Carbon Pollution Reduction Scheme, which offered relief for just one year.

Tony Windsor’s 2008 Climate Protection Bill called for a tax on all major sources of emissions and, like the Greens, and end to fuel rebates for industry – including agriculture.

“Rob Oakeshott and Tony Windsor have tried to make themselves the heroes of the piece in terms of the omission of petrol from the initial stages of their carbon tax,” Senator Boswell said.

“But the reality is that they, and the Greens, all want it in - and they have the whip hand over Julia Gillard.

“An extension of the tax to petrol, and an attack on fuel rebates for industry, including agriculture, is only a matter of time.”
