Building and maintaining trust in organisations is a common concern among institutions with activities that involve the management of hazardous materials or contaminated sites, or have the potential for exposure both to workers and members of the public. This subject was identified and discussed at the first Workshop of the RWMC Forum on Stakeholder Confidence, and highlighted by the CRPPH Villigen workshops, and was then judged to merit further elucidation. To carry discussions about this important topic forward, the RWMC and the CRPPH agreed to hold a joint topical session on the subject. The session was designed to enrich the reflection that is being made in the stakeholder area within the two committees, and to stimulate the open exchange of views to provide additional bases for further analysis. This document comprises the papers presented at the meeting, held in Paris, France on 13 March 2002.
