Gillard’s decision to introduce a carbon tax deserves credit. It is a brave move and it is the right idea, poorly executed. I say this as someone partial to a carbon tax over emissions trading. A carbon tax is a more direct economic strategy in the early stages of energy market transformation. To explain why, I need to give a bit of background. Forgive me if I put you to sleep.
Carbon trading works by putting environmental standards front and centre and letting the carbon price bob like a volley ball around it. This is potentially dangerous as it can create an enormous amount of instability in investment decisions. (When things are unstable, people tend to do nothing.) It only works when you have a flurry of commercially viable low carbon energy technologies at hand. In these cases, it only takes a slim carbon price to change energy behavior at the margins.
A carbon tax, by contrast, is geared directly at investment decisions. You can slowly and steadily increase the tax until the floodgates for technology are unleashed.
So what? Gillard would have been better off sticking to a carbon tax instead of locking in an ETS in 3-5 years time. Nonetheless there is a bigger elephant in the room: nuclear technology. Labour’s decision to embargo nuclear is like trying to solve a problem while hiding the answer. Technologies take decades to mature and nuclear is far more technically and commercially mature as a technology than wind or solar.
In my opinion, it is no longer credible in the modern age to be serious about de-risking climate change and be against nuclear energy in this country or anywhere else.
