Nuclear power plant construction CO2 emissions?

Is is true that building one nuclear plant emits the same amount of carbon dioxide as one coal plant operating for 100 years or so?

Everyone talks about how much CO2 various energy sources emit when in operation, but what about the entire life cycle emissions of each energy source, including the carbon emissions of building the power plant, solar panel, wind turbine, etc.? Can anyone list the CO2 emissions for building each of the various energy sources as well as their operating emissions?

Utter rubbish.

Studies have already been done that look at the carbon footprint over the complete lifecycle for various energy generation types. Here’s a summary, in gCO2/kWh:

Coal: > 1000
Coal gasification: 800
Oil: 650
Gas: 500
Biomass: 25 to 93
Photovoltaics: 35 to 58
Wave/tidal: 25 to 50
Hydroelectric (reservoir): 10 to 30
Hyroelectric (run of river): 5
Wind: 5
Nuclear: 5

Nuclear power has one of the lowest carbon footprints available, and is the only low-footprint baseload technology that can be deployed anywhere, regardless of local weather conditions. Coal produces 200 times the carbon footprint of nuclear on a watt-for-watt basis.

Nobody who is serious about stopping global warming should be against nuclear power.
