What is SRI for ESG?

Good article at Newground, on socially responsible investing with on emphasis on shareholder activism, such as voting proxies to pressure companies to do better on ESG - Environmental, Social, and Governance factors.  Stakeholders become stockholders and vote their shares to influence management. Seems like Capitalism with a twist for the better. Ownership has it priviliges. And we can pool dollars to own and vote shares through intermediaries, like a socially conscious investment fund.
