This chapter provides a comprehensive analysis of ethical frameworks and guidelines for the responsible development, deployment, and governance of artificial intelligence (AI). The chapter examines global initiatives, including frameworks from organizations such as the European Union (EU), IEEE, NIST, UNESCO, the United Nations (UN), and more, emphasizing their core principles such as transparency, accountability, inclusivity, fairness, and human-centred values.
