The Harvard Business Review (HBR) recently published its 2016 list of the world’s top 100 CEOs. As in the past, HBR’s staff looked at the financial and ESG (environment, social, governance) performance of the CEOs of 1,200 large companies. They used a measure of financial performance developed by a team of Harvard academics for 80% of their score. The remaining 20% came from averaging two overall measures of corporate sustainability performance, including CSRHub.
