I am happy to quit while I am ahead. The reality is that the Liberal Party used to believe in markets. The carbon price we introduced was all about achieving a market mechanism. That is what we need to do. We need to make sure we change behaviours. The best possible way to do that is by putting a price on the businesses that emit the most. Having bureaucrats in Canberra pick the best possible mechanism is a very risky game. Putting all your faith in that magic dirt that scientists have said will not produce the offsets that we need is a very risky game. I ask those opposite to understand our principal position in terms of pricing carbon.
