I could take a shot at the beginning. Maybe you can repeat the second part of the question.
Certainly in terms of the aluminum production that you refer to, and the steel production, cement production, our electricity-generation capacity and how clean that all is, you can look at our supply chain and how close we are to the United States of America. There are also the transportation greenhouse emissions between Canada and the U.S. compared with bringing materials offshore. We have an opportunity to leverage this green procurement of infrastructure and the manufacturing of American goods, and I think that might be the sweet spot. I would agree with you, and I think the Canadian embassy and others are working on that.
There are all kinds of examples. In terms of lithium battery supply, we're the fourth-largest lithium battery supply manufacturer in the world and the greenest. There are all kinds of aspects of Canadian industry that are greener and provide better alternatives to production in the United States, and they should be exempt from buy America policies.
