Under an ESG model, companies are not only rated using traditional metrics, such as revenues and the quality of goods and services offered, but also on a variety of social justice metrics, such as their carbon footprint, air quality of a business' supply chain, and having the "right" ratio of Asians to Hispanics working in the company, among many other factors.
Thousands of companies have already adopted ESG standards around the world, including an estimated 82% of large companies in the United States, and to this point, they have done so voluntarily.
