Abstract
Engineering ethics concerns the decisions and actions of engineers, individually as well as collectively. It exists as a field of teaching and research since the 1980s. The professional approach to engineering ethics that initially was dominant in the field is discussed, and codes of ethics are explained. Various general ethical issues in engineering like whistle-blowing, loyalty, conflicts of interests, risk and safety, and the environment and sustainability are highlighted. Attention is also paid to recent developments in engineering ethics, in particular to how new technologies may give rise to new ethical issues, and to more proactive approaches to engineering ethics, like value-sensitive design and responsible innovation.
