The Environment Needs Nuclear

Part 2:
Because nuclear reactors are virtually greenhouse gas emissions-free, using them to generate electricity can help arrest the planetary danger of global warming and radical climate change. Any realistic strategy to avert this unprecedented threat requires nuclear energy.

Carbon dioxide (CO2) is the main substance associated with the greenhouse effect and global warming. Fossil fuels (coal, oil and gas) - whether used for electricity or to power vehicles - disperse CO2 directly into the air. Nuclear energy produces almost no emissions of CO2 or any other greenhouse gas.

Climate experts warn that we must cut overall global CO2 emissions from 25 billion tonnes annually to 10 billion, even as overall energy production increases.

Today's nuclear reactors (when viewed as an alternative to coal-generated electricity) are already preventing emissions of 2.5 billion tonnes per year of CO2 - which is about half the CO2 emitted by the world's motor vehicles. Expanded use of nuclear energy could do far more.

Nuclear energy also relieves general air and surface pollution. Reactors emit neither the smoke that causes smog and respiratory problems nor any of the gases responsible for the acid rain that kills forests and lakes.

When evaluated for life cycle ecological impact - weighing resource use, health effects and consequences of waste - nuclear energy outranks all other major power options and is on a par with the best renewables.
