Last year, Amazon CEO Jeff Bezos ranked No. 1 on Harvard Business Review‘s list of the world’s 100 best-performing CEOs. This year, however, Bezos comes in at No. 87.
The reason for this precipitous drop, HBR says, is that, unlike previous years’ lists, the 2015 ranking judges CEOs on their environmental, social, and political impacts, as well as financial success. So while Bezos remains the top-performing CEO when it comes to financial measures, Amazon received poor marks for social responsibility.
In recent years, Amazon has been criticized for its treatment of warehouse workers, for the cutthroat corporate culture at its Seattle headquarters, and for paying low taxes in Europe.
