This conference of 74 nations sponsored by the International Atomic Energy Agency and the Organization for Economic Cooperation and Development affirmed nuclear energy's contribution to environmental protection and sustainable development. "A vast majority of participants affirmed that nuclear power can make a major contribution to meeting energy needs and sustaining the world's development in the 21st century, for a large number of both developed and developing countries," because "nuclear power does not generate air pollution or greenhouse gas emissions," it "provides competitively priced electricity, ...contributes to security of supply and to the stability of energy prices," and can produce "potable water and hydrogen."
