World Federation of Engineering Organizations

The World Federation of Engineering Organizations (French: Federation Mondiale des Organisations d'Ingenieurs; WFEO) is an international, non-governmental organization representing the engineering profession worldwide.

Founded in 1968 by a group of regional engineering organizations, under the auspices of the United Nations Educational, Scientific and Cultural Organizations (UNESCO) in Paris, WFEO is a non governmental international organization that brings together national engineering organizations from over 90 nations and represents some 20 million engineers from around the world. WFEO is part of the United Nations system as an NGO in official relations with UNESCO (associate status) since its foundation, and as taking part in the work of its main bodies, mainly the United Nations Economic and Social Council (ECOSOC) and its specialized agencies, notably the United Nations Industrial Development Organization, the United Nations Environment Programme. At the UN ECOSOC, WFEO co-organizes with the International Science Council the Scientific and Technological Community Major Group.

In 2019, based on proposal by WFEO, the UNESCO's General Conference approved the creation of the UNESCO World Engineering Day for Sustainable Development, to be celebrated on 4 March of each year. Since then, WFEO has been coordinating the related celebrations around the world, through its membership and partnering institutions.
