Life-Cycle Emissions

Nuclear energy’s life-cycle carbon emissions are comparable to those of renewable energy sources.

Independent studies show that nuclear energy’s “life-cycle” emissions of carbon dioxide are about the same as wind and geothermal power and significantly less than other electricity sources. A life-cycle measurement takes into account the facility’s construction, the mining and processing of fuel, routine operation, disposal of used fuel and the ultimate dismantling of the facility—in other words, its entire life cycle.

Which of these electricity sources has the lowest life-cycle emissions of carbon dioxide?

  1. Coal
  2. Natural gas
  3. Nuclear energy

Answer: 3. Over its entire life-cycle, including manufacturing and construction, coal and natural gas have more than twice the carbon dioxide emissions of nuclear energy.
