This PhD project addresses a critical research gap by exploring the relatively unexamined relationship between board diversity and Corporate Social Responsibility (CSR) in European companies. It aims to understand how diverse characteristics of board members, such as gender, nationality, and professional background, influence CSR initiatives. The project's purpose is to provide new insights into the efficacy of corporate governance in driving CSR efforts, especially in the context of Europe's unique regulatory and societal landscape. This research is significant for enhancing our understanding of the interplay between board diversity and CSR in the European corporate sector.
