* The aggregated total for nuclear power is only about two-thirds of the UK “average” figure. This is because nuclear power is supplied disproportionately to industry rather than domestic customers. Aggregated coal and gas figures are both slightly higher than the average figures.
Other impacts
Coal power plants also emit sulphur dioxide which leads to acid rain, as well as other pollutants.
Note that the figures for carbon dioxide emissions are for emissions directly related to electricity generation and take no account of lifecycle emisions.
For nuclear power in particular there are carbon dioxide emissions related to construction and the mining and processing of the uranium fuel.
The nuclear waste figure does not include intermediate and low-level nuclear waste. Though less radioactive, these lower level wastes are created in much larger volumes, are still dangerous, and represent a disposal problem.
