Effective ESG (Environmental, Social, and Governance) leaders possess seven key qualities: a strong moral compass, curiosity to understand problems thoroughly, unwavering commitment, creativity to harness sustainable practices for revenue generation, courage to drive large-scale organizational changes, the ability to cooperate and form networks, and consistency in applying high standards to both employees and themselves. These qualities enable them to lead organizations successfully through ESG transitions, driven by a genuine belief in ethical responsibility rather than just attracting investors. Such leaders are crucial in addressing the significant sustainability challenges faced by both public and private sectors.
