I don't think so. I think any intervention leads to a distortion. That might be a distortion you're trying to achieve. For example, the government decided in budget 2019 that it wanted to encourage businesses to acquire zero-emission vehicles, so it allowed an immediate writeoff. There's a clear objective there. We can measure the reduction in the cost of acquiring those. We look at that and there are efficiencies and inefficiencies in it, but on balance we consider it to be an efficient tax measure to achieve a very clear objective, which was to encourage the purchase of zero-emission vehicles by businesses.
When we look at the fossil fuel subsidies, we have to measure all of the costs and benefits associated with them and, on balance, whether those are efficient or inefficient in achieving the objective.
