The United Nations Industrial Development Organization (UNIDO) (French/Spanish acronym: ONUDI) is a specialized agency of the United Nations that assists countries in economic and industrial development. It is headquartered at the UN Office in Vienna, Austria, with a permanent presence in over 60 countries As of April 2019, UNIDO comprises 170 member states, which together set the organization's policies, programs, and principles through the biannual General Conference.UNIDO was established in 1966 by the UN General Assembly to promote and accelerate the industrialization of developing countries, which were emerging from decolonization in record numbers and with little to no industrial base. In 1979 it became one of the 15 specialized agencies of the UN, with its new constitution coming into force in 1985. Since its founding, the organization has restructured and reformed several times; the 2013 Lima Declaration expanded its mission to include promoting "inclusive and sustainable industrial development" (ISID), defined as benefiting greater numbers of people while safeguarding the environment.UNIDO is a member of the United Nations Development Group, a coalition of UN entities aimed at fulfilling the Sustainable Development Goals.
