The European Astronomical Society (EAS) is a society of professional astronomers working in Europe, with currently around 2500 members. It is supported by a network of affiliated societies: close to 30 national societies in most countries in Europe. Among other activities, the EAS organises an annual meeting which attracts well over 1000 participants and provides a forum for both scientific discussions and collaborations, and discussions about issues of science policy. The EAS Council formally adopted, in January 2018, the report produced by the EAS Ethics Working Group entitled EAS Ethics Statement and Guidelines for Good Practice. It is being used by organisers and participants of the EAS Annual Meeting, and is promoted as a tool for discussion and good practice throughout our field. The Ethics Statement covers a very wide range of topics, including Conduct towards others, Research, Publication and authorship, Peer review, Conflicts of interest, Organisation of and professional conduct at conferences and meetings, Fair recruiting, Widening access to our profession, Recommendations for fair employment practices, and Ethics in publishing. We will outline the history and contents of the EAS Ethics Statement and how it will be further developed, and thus illustrate how a scientific society can provide guidance.
