Daniel Yergin is the Pulitzer-winning author of The Prize, the definitive work on the modern oil oligopoly, and one of the world’s leading authorities on the fossil fuel industry. He’s also a vice-chairman of IHSMarkit, the large data company, which is in the process of completing a massive $44 billion merger with S&P Global (regulators willing) to create a financial data powerhouse to compete with the likes of Bloomberg, Reuters, and DowJones. When that merger closes, expected in December, Yergin will be a vice-chairman of the combined company. He is also a leading intellectual, who sits on the boards of both the Council on Foreign Relations, where I am a member, and the Brookings Institution.
