The findings are presented in units of global warming potential per unit of electrical energy generated by that source. The scale uses the global warming potential unit, the carbon dioxide equivalent (CO 2 e), and the unit of electrical energy, the kilowatt hour (kWh). The goal of such assessments is to cover the full life of the source, from ...
Nuclear energy produces about 10 grams of carbon dioxide per kilowatt hour, compared to about 500 for fossil gas and 1000 for coal. Like all energy sources, various life cycle analysis (LCA) studies have led to a range of estimates on the median value for nuclear power, with most comparisons of carbon dioxide emissions showing that nuclear ...
The Intergovernmental Panel on Climate Change found a median value of 12 g (0.42 oz) equivalent lifecycle carbon dioxide emissions per kilowatt hour (kWh) for nuclear power, being one of the lowest among all energy sources and comparable only with wind power.
As a percentage of all anthropogenic greenhouse gas emissions, carbon dioxide (CO 2) accounts for 72 percent (see Greenhouse gas), and has increased in concentration in the atmosphere from 315 parts per million (ppm) in 1958 to more than 375 ppm in 2005. [63] Emissions from energy make up more than 61.4 percent of all greenhouse gas emissions. [64]
Older nuclear power plants, like ones using second-generation reactors, produce approximately the same amount of carbon dioxide during the whole life cycle of nuclear power plants for an average of about 11g/kWh, as much power generated by wind, which is about 1/3 of solar and 1/45 of natural gas and 1/75 of coal.

That legislation requires the N.C. Utilities Commission to approve a plan every two years that targets a goal of a 70% reduction in carbon dioxide emissions from Duke Energy’s 2005 levels by ...
An emission intensity (also carbon intensity or C.I.) is the emission rate of a given pollutant relative to the intensity of a specific activity, or an industrial production process; for example grams of carbon dioxide released per megajoule of energy produced, or the ratio of greenhouse gas emissions produced to gross domestic product (GDP).
