The World Commission on Environmental Law (WCEL) is a network of environmental law and policy experts from all regions of the world who volunteer their knowledge and services to IUCN activities, especially to those of the IUCN Law Programme. WCEL functions as an integral part of the IUCN Environmental Law Programme (ELP), which includes the World Commission on Environmental Law and the Environmental Law Centre.
With a worldwide membership, WCEL not only takes the lead in projects of its own, but also provides a source of expertise for the Environmental Law Centre and other parts of IUCN. The Commission thus serves as the principal source of legal technical advice to the Union, its members and its collaborating institutions on all aspects of environmental law. It supports action by international governmental organisations, governments and non-governmental organisations to improve or develop legal and institutional infrastructure best attuned to natural resources conservation in the context of sustainable development. WCEL's goal is to demonstrate the vital importance of such infrastructure within national and international strategies for environmental conservation, including the sustainable use of natural resources within and beyond national jurisdictions.
