People say, well, we've got gridlock in Congress, and we have an effective institution that maybe could do something to bring us toward greener equilibriums. And that's really a fundamental question that is about climate change, but it's also about, you know, American democracy. By making the Fed wade into more politicized territory, like choosing which companies to lend to based on their climate credentials, you're making those decisions in a place less bound by politicians and elections, less bound by democracy. You're also risking the very thing that makes the Fed special - its independence. But others argue, in a crisis, maybe the ends justify the means. (NPR)
