Portfolio 21 will invest only in energy companies that have limited capital investments dedicated to the expansion of new nuclear generation. We do not support the expansion of nuclear power because we consider the cost of new nuclear installations to be high relative to the environmental, health, and safety risks associated with nuclear reactors and waste. A typical reactor will generate 20 to 30 tons of high-level nuclear waste annually. There is no known way to safely dispose of this waste, which remains dangerously radioactive until it naturally decays, which according to the U.S. Environmental Protection Agency is approximately 10,000 years.
