No. Those are all voluntary.
As you know, the first thing about improving performance is to measure. We entered the carbon disclosure project because we started measuring our greenhouse gases. Once you measure them, then you look down and ask what you can do. “Towards sustainable mining” is a systematic way of managing the most important risk you have—the tailings.
We've recently included biodiversity. In Nunavut, biodiversity is very important. The caribou is very important to the Inuit because they still need it. It's a main staple of their diet. So if it's important to them, it's important to us. That's why we're putting money and effort into understanding the caribou migration patterns. In fact, in our Meliadine project, we changed the location of the site because it could have been interfering with the migration pattern. You live in that territory if you have a mine there, so you have to protect what's important to the Inuit, and the caribou is very important.
