The International Atomic Energy Agency [3], which promotes nuclear power, concluded that "even under the most favourable circumstances," nuclear power wouldn't slow global warming [4]. An IAEA report predicted that global warming would decrease more if "no new [nuclear plants were] built beyond those already planned," because "the world would have to be so prosperous to afford" a significant increase in nuclear plants that greenhouse gas emissions "from fossil fuels would have grown even faster." The IAEA's findings undercut the Nuclear Energy Institute [5]'s claims that "nuclear energy ... helps to keep the air clean, preserve the Earth's climate, avoid ground-level ozone formation and prevent acid rain."
