Abstract Issue/Problem The World Health Organisation (WHO) and Association of Schools of Public Health in the European Region (ASPHER) roadmap for the professionalisation of the public health workforce has noted ethics as a pillar for professionalisation. It also highlights the need for code of ethics and professional conduct for all public health professionals and institutions. The Global Network for Academic Public Health (GNAPH), in collaboration with EUPHA, ASPHER, and the UK Faculty of Public Health has been working together for a code of ethics. Description of the problem The WHO/ASPHER group asked for a framework to be developed by the expert group as part of the rollout of the professionalisation agenda. The objective of this work was to develop a guide that is applicable to different countries within Europe to develop their own of code of ethics and conduct. A modified Delphi approach to building consensus amongst professionals in ethics included law, academia, and public health professionals. The questions sought to be answered were what and how to develop a framework and what should be included in the guide for creating a public health code of ethics. Results Throughout this method we developed five values, and twelve principles that are essential for the development of a code of ethics through a consensus building exercise. This framework was the first of its kind as part of the professionalisation agenda for different regions. There will be ongoing work piloting this framework in practice with various professional groups and institutions. Lessons Throughout this process, the need and demand across the public health community for ethical education and development of code of ethics was made evident. Collaboration between academics, ethicist, lawyers, and public health professionals and policy makers were key in developing a public health code of ethics. Identifying the challenges with monitoring and evaluating of its implementation a public health code of ethics. Key messages • Ethics, and a code of ethics are an essential component of the professionalisation agenda of the public health workforce. • There is need for continued collaboration and partnership with public health professionals and institutions in enacting its implementation and evaluation.
