The International Council of Environmental Law (ICEL) is a world-wide association of senior environmental law experts, who play a role in the formation of international environmental law. Founded in 1969, ICEL celebrated its 50th anniversary in 2019. The need for deploying ICEL expertise is greater now more than ever, as environmental degradation trends worsen, and the face of the Anthropocene epoch is ever more visible. ICEL was accredited by the UN Economic and Social Council, ECOSOC, in 1973, and maintains “General Consultative Status” as observer. ICEL regularly presents expert opinions to UN bodies and organs. The status allows ICEL members access to the UN meetings and premises. ICEL is also accredited to the UN Environment, the UN Framework Convention on Climate Change Secretariat, the Convention on Migratory Species Secretariat, and other international organizations. It is a member of the International Union for the Conservation of Nature (IUCN). ICEL maintains representatives in Bonn, Geneva, Nairobi, and New York. Because of its ECOSOC status and UN accreditations, ICEL is allowed to participate in the current negotiations such as the intergovernmental conference to draft a new treaty on the conservation and sustainable use of marine biological diversity in areas beyond national jurisdiction (BBNJ) under the UN Convention on the Law of the Sea, and the UN General Assembly consultations to strengthen the implementation of international environmental law, “towards a Global Pact for the environment”.
