Vanguard Group said Monday it has urged companies to disclose how climate change could affect their business and asset valuations, reflecting how the environment has become a priority for the investment industry. Vanguard does not have a history of supporting climate activists, but Glenn Booraem, Vanguard's investment stewardship officer, said the issue and shareholder proposals have evolved. "Our support for these proposals is not a matter of ideology, it's a matter of economics," he said. "To the extent there are significant risks to a company's long-term value proposition, we want to make sure there is long-term disclosure of those risks to the market."
