Week in Green: What ESG Actually Means

This week, we’re going to work our way from large, philosophical problems (what makes an investment ethical?) to the small and practical (why does Florida have so many iguanas, and how can we get rid of them?)

Sustainable investing is one of the hottest trends on Wall Street. Trillions of dollars are rushing in as consulting firms and private foundations spread the gospel. But no one is entirely sure what ESG is beyond the literal (environmental, social and governance) or exactly how to define it. Metrics are self-reported and often hard to measure, tracking everything from carbon emissions to boardroom diversity. Greenwashing is a perennial concern.
