The reason why—and it is unusual, of course, for business to say, yes, actually we would like a mandatory regime that we can all be a part of—is because actually it is now widely understood that climate change does represent a real material risk to business. But it is difficult on a voluntary basis for companies to report, because, in showing the risks that they are exposed to, if their competitor businesses don't also do that then that company, no matter how good its intentions, is exposing itself in ways that its competitors are not. So the reason why mandatory reporting was so widely supported in the private sector was because people felt that it would introduce a level playing field and actually make it easier for them to report. And obviously the financial sector fund managers, analysts, directors and so on are also very interested in ensuring that this information comes to light, because of the very material risks.
