In July 2002, the International Conference of Women Engineers and Scientists (ICWES12) delegates supported the creation of the International Network of Women Engineers and Scientists (INWES). The vote from representatives of 30 countries was unanimous. The following April 2003, INWES was incorporated as a non-profit corporation under the laws of Canada.
