ESG companies meet one or more of the widely accepted environmental, social, or governance criteria. Depending upon the ESG certification platform, the company will receive a specific score that is based upon the rating criteria. It is important to dig into the criteria to understand how companies are being evaluated and avoid greenwashing. Various ESG tracking organizations provide lists of ESG companies. You won’t find tobacco companies on an ESG company list due to the health risks of smoking. Companies who make firearms are also usually omitted. A quick internet search will yield multiple lists of ESG companies to use as a springboard for your ESG company research.
