This article explores the role of ethics committees in ensuring ethical research and innovation, which is essential for maintaining trust in science and innovation. The paper argues that the ethics infrastructure must function at the levels of research and innovation institutions, as well as regional and national levels, and should follow agreed-upon rules and requirements. The changing role of ethics committees is discussed, emphasizing their involvement in investigating potential research misconduct and coordinating the activities of all ethics committees within an institution. The article concludes that for a research and innovation institution, it is of crucial importance to consider the entire ethics infrastructure, including the functions of different ethics committees and ways of implementation through transparency, involvement, policies, procedures, and communication to safeguard that both researchers and the public have trust in ethics infrastructure and ethics committees.
