Understanding the significance of board composition is crucial for evaluating a company's ESG score. The size of the board affects functionality and dynamics, with a moderate-sized board between 8 to 15 members generally striking a good balance. Legal requirements vary, but best practices suggest a mix of skills, experience, age, and cultural backgrounds for a well-rounded governance framework. Accurately reporting board composition requires transparency, detailing independent and executive directors, and employee representatives where applicable. The rationale behind the board's composition should reflect effective governance and plans for evolving the board in line with strategic goals and ESG criteria for a stronger ESG score.
