Thank you. I'll be very fast. It's a great question.
The aluminum industry is interesting in that there are investments in new high-efficiency facilities like in Kitimat--$2 billion, which is reducing emissions significantly. Those emissions can be used through a trading mechanism to help their sectoral colleagues in Quebec to meet targets. So here's a good example of flexibility in trading, where there might not be such a big hit.
The other interesting thing about aluminum is that the technology is improving to reduce those emissions. It has improved significantly, and it continues to improve. With an emission price, the deployment of that sort of technology improvement may be accelerated. The aluminum industry may not be the best example for talking about impact, because there are opportunities in the next while to reduce the cost of possible carbon dioxide.
