I understand your opinions on this. I'm sorry. You're here as an expert witness, and I'm trying to understand your expertise in gauging the impact of climate policies on the environment. I know there are a lot of rumours or shared beliefs about this, but I just want to ascertain that you have not done research or that you do not have any basis, other than your beliefs, to believe that this doesn't work. We have seen emissions go down by 8%, and 300 experts in climate science and economics have shown that this is one of the most effective ways to reduce pollution.
On another front, I'm wondering about the price on pollution, which we're talking about. Ninety-three per cent of farm fuels are exempt from the carbon levy. Do you know how much of your fuels are taxed and what your carbon tax would be compared to your overall expenses?
