The ESG ranking measures a company's exposure to long-term environmental, social, and governance risks. These risks -- involving issues such as energy efficiency, worker safety, and board independence -- have financial implications.
The financial rating is generated by analyzing the market behavior of major stocks and compares them on a common scale of performance.
