I'll say a few words and then maybe I'll ask Michel to talk a little bit about ISSB. He's been quite involved, and it is important. It's important for an investor to have consistent reproducible measurements. Think about the carbon intensity in different companies and, as we've talked about already, the ability to compare companies across geographies, across industries. It's critically important. Just as an example, in our portfolio we do publish, in our annual report, the carbon intensity of our portfolio, but of that, only around 30% to 35% of the numbers we have are actually reported by companies. For 60% to 70% of the numbers in there, we are using industry averages. We're proxying to get to what we believe is a representation of our portfolio, and it moves around. It's volatile, because every quarter—and this is a good thing—more companies come out and disclose more information and there are restatements and people refine the methodology, but it adds volatility.
As we think about the transition to net zero when we have stable, consistent, comparable measures, it will be really important, which is one of the reasons that as a firm we're actually dedicating time to being involved and trying to be part of this process.
