Will a carbon tax double the price of petrol?

Possible future petrol prices under different oil market/carbon price scenarios (CSIRO)

Tony Abbott made a surprising claim on Sunday that a $40/tonne carbon tax would increase the retail price of electricity by 100%. Fortunately, John Quiggin has ‘done the maths’ on Abbott’s assertion and points out that it would result in a much lower increase in the retail price to households – around 20%.

So let’s look at the likely effect of a carbon tax on the price of petrol. This CSIRO report, Fuel for Thought, estimates that a $40/tonne emissions permit would only increase the retail price of petrol by 10 cents per litre. So the additional cost of the $23/tonne carbon price touted by the Greens would seem to be no more than the weekly fluctuations in price at my local servo!

That’s hardly a great big new tax. But what’s important from a policy perspective is that a price on carbon of this order isn’t really going to have a significant effect on what we drive and how we drive. Read the rest of this entry »

Is Cash for Clunkers a great big new mistake?

Clunker - 1992 Nissan Pulsar

Did Julia Gillard read my post last Thursday arguing that she should take action in the election campaign to improve the fuel efficiency of Australia’s cars? Possibly not, but I wish now I’d left in the sentence saying that whatever happens, please don’t make the same mistake as President Obama and bring in a poorly-designed “cash for clunkers” program!

Now the PM has announced today her own Cash for Clunkers initiative (here and here) with the ostensible purpose of saving one million tonnes in carbon emissions (this is not an annual saving but the total over the life of the scheme).

The scheme will be financed by cutting back other programs, including the solar and carbon capture and storage programs, and the renewable energy bonus scheme (see here).

President Obama at least had the excuse that his scheme was primarily a pump-priming exercise designed to lift consumer spending in the wake of the GFC. In our context however, Cash for Clunkers looks like seriously bad policy. Even on the skimpy detail released today, it is evident there are clear failings. Read the rest of this entry »
