Discussing cutting-edge debates in the field of international ethics, this key volume builds on existing work in the normative study of international relations. It responds to a substantial appetite for scholarship that challenges established approaches and examines new perspectives on international ethics, and that appraises the ethical implications of problems occupying students and scholars of international relations in the twenty-first century. The contributions, written by a team of international scholars, provide authoritative surveys and interventions into the field of international ethics. Focusing on new and emerging ethical challenges to international relations, and approaching existing challenges through the lens of new theoretical and methodological frameworks, the book is structured around five themes: • New directions in international ethics • Ethical actors and practices in international relations • The ethics of climate change, globalization, and health • Technology and ethics in international relations • The ethics of global security Interdisciplinary in its scope, this book will be an important resource for scholars and students in the fields of politics and international relations, philosophy, law and sociology, and a useful reference for anyone who wishes to acquire ‘ethical competence’ in the area of international relations.
