Engineering ethics is the field of applied ethics which examines and sets standards for engineers' obligations to the public, their clients, employers and the profession. This article addresses the subject for both professional engineers and other engineers. Engineering does not have a single uniform system, or standard, of ethical conduct across the entire profession. Ethical approaches vary somewhat by discipline and jurisdiction, but are most influenced by whether the engineers are independently providing professional services to clients, or the public if employed in government service; or if they are employees of an enterprise creating products for sale. In the United States the first are usually licensed Professional engineers, are governed by statute, and have generally consistent codes of professional ethics. The latter, working as engineers in industry, are governed by various laws including whistleblowing, and product liability laws, and often rely on principles of business ethics rather than engineering ethics.
