Nations existed and were integrated into the system, others were created by the League of Nations and were integrated by its successor, while others were created by the United Nations itself to meet emerging needs. The following is a list of the specialized agencies reporting to the Council: Food and Agriculture Organization (FAO) International Civil Aviation Organization (ICAO) International Fund for Agricultural Development (IFAD) International Labour Organization (ILO) International Monetary Fund (IMF) International Maritime Organization (IMO) International Telecommunication Union (ITU) United Nations Educational, Scientific and Cultural Organization (UNESCO) United Nations Industrial Development Organization (UNIDO) United Nations World Tourism Organization (UNWTO) Universal Postal Union (UPU) World Bank Group (WBG) International Bank for Reconstruction and Development (IBRD) International Development Association (IDA) International Finance Corporation (IFC) Multilateral Investment Guarantee Agency (MIGA) International Centre for Settlement of Investment Disputes (ICSID) World Health Organization (WHO) World Intellectual Property Organization (WIPO) World Meteorological Organization (WMO) "World Economic and Social Survey 2011: The Great Green Technological Transformation" In a report issued in early July 2011, the UN called for spending nearly US$2 trillion on green technologies to prevent what it termed "a major planetary catastrophe", warning that "It is rapidly expanding energy use, mainly driven by fossil fuels, that explains why humanity is on the verge of breaching planetary sustainability boundaries through global warming, biodiversity loss, and disturbance of the nitrogen-cycle balance and other measures of the sustainability of the earth's ecosystem". UN Secretary-General Ban Ki-moon added: "Rather than viewing growth and sustainability as competing goals on a collision course, we must see them as complementary and mutually supportive imperatives".
