In 2015, WIOMSA achieved another milestone through its accreditation with UNEP as a major stakeholder after going through a rigorous review process. Accreditation brings many advantages with respect to participation in the work of UNEP’s Governing Bodies, such as the United Nations Environment Assembly (UNEA) and its subsidiary bodies. The purpose of accreditation is to provide non-governmental organizations with observer status to the UNEA and its subsidiary bodies according to Rule 70 of the rules of procedure of the UNEA.
