The World Commission on Environmental Law is led by a Steering Committee consisting of the Chair, the Deputy Chair and the Steering Committee Members. The Director of the Environmental Law Centre is an ex officio member of the Steering Committee. The Steering Committee meets at least once a year to discuss the implementation of the IUCN Law Programme and to decide on the future of Commission initiatives. The Commission is primarily supported by a WCEL Executive Officer and by the staff of the IUCN Environmental Law Centre, especially the Legal Officers.
The word "interdisciplinary" best characterises the Commission and its structure: environmental law involves many intertwined disciplines and this has been accommodated in the Commission by a loose, theme-oriented structure. Specialist Groups are organised to meet demands of a special effort in promoting conceptual work in environmental law. In addition, individual members collaborate on projects arising from their respective areas of expertise through the organisation of consultations, internet discussion fora and ad hoc Working Groups.
Members of the Commission come from diverse areas of expertise within environmental law and policy, but all share a commitment to work actively towards the progress of conservation law. They serve in their personal capacity, although they might come from governmental or non-governmental organisations, might be active in private law practice, attached to a university or an international organisation. They represent every region of the world and their interests and expertise span the full spectrum of environmental law from pollution issues to those related to biological diversity conservation.
