One of Wall Street's newest strategies is to invest according to Environmental, Social and Governance issues, better known as ESG. It's a way to invest according to a certain ethical philosophy.
"Environmental, social and governance (ESG) criteria are a set of standards for a company’s operations that socially conscious investors use to screen potential investments. Environmental criteria consider how a company performs as a steward of nature. Social criteria examine how it manages relationships with employees, suppliers, customers, and the communities where it operates. Governance deals with a company’s leadership, executive pay, audits, internal controls, and shareholder rights," according to Investopedia.
