For example, in his 2021 letter to CEOs, BlackRock's Fink asked companies to disclose a "plan for how their business model will be compatible with a net zero economy"—that is, "one that emits no more carbon dioxide than it removes from the atmosphere by 2050, the scientifically-established threshold necessary to keep global warming well below 2ºC." (See this PubCo post .) And BlackRock Investment Stewardship has stated that, "where corporate disclosures are insufficient to make a thorough assessment, or a company has not provided a credible plan to transition its business model to a low-carbon economy, including short- medium- and long-term targets, we may vote against the directors we consider responsible for climate risk oversight."
