As the only person not representing a country, Bloomberg, in his new role as the U.N.’s special envoy for climate action, seemed like a substitute for American leadership—an alternative to the climate-denying Trump Administration, which Bloomberg called “a meshuggener.” But he immediately brushed aside the idea that the federal government, in this country, at least, can have a major impact on fuel sources or climate policy. “Coal will go away in any place where there’s a free market, for sure, because the market just forces that, the economics force it. OK, the federal government can change some environmental regulations, but companies are going to put in the environmental safeguards anyway. Their stockholders are insisting on it, their employees are insisting on it, their customers are insisting on it, and, at the state level, they’re insisting on it.” Of greater concern are countries in which “the government has set the price for coal or whatever and is subsidizing it.” Last fall, McKenna and Perry founded the Powering Past Coal Alliance, which aims, in part, to help these countries adopt cleaner fuels. 60 nations, states, cities, and companies have so far joined its polyglot roster.
