In recent years, Environmental, Social, and Governance (ESG) principles have become a cornerstone in the corporate landscape, influencing decision-making and operations across various sectors. As investors, consumers, and regulatory bodies place increasing emphasis on sustainable and ethical practices, US companies have recognized the strategic and reputational value of adopting ESG frameworks (Paapa, 2024). This shift has prompted the establishment of dedicated ESG departments to manage and streamline these principles, aligning corporate actions with broader societal and environmental expectations. The role of these departments extends beyond compliance; they help embed sustainability and ethical governance within the core corporate structure, creating value for both the organization and its stakeholders. This article examines the purpose, function, and impact of ESG departments within corporations. We will explore how these departments integrate into existing corporate structures, the key policies they champion, and the benefits and challenges they bring to modern organizations. By understanding the transformative influence of ESG departments, we can better appreciate their role in shaping the future of responsible business practices in the US (Tariq, 2024).
