I think it's a valid question, and I don't think it's about penalizing anyone. Clearly, most of us, hopefully all of us, around this table understand that climate change is a major challenge and a huge risk to society. The solution involves changes. The best solution involves changes that have the least disruption to people's lives and provides the most benefits. That's why carbon pricing is the prime policy option that I've heard of. It allows people to choose. It gives them the incentive to choose the options that work best for them.
