Carbon Dioxide Emissions
As part of the fuel mix disclosure, suppliers also have to show the carbon dioxide emissions resulting from the electricity that they supply to customers.
CO2 emissions are a major contributor to global climate change, the most serious environmental threat facing the world today.
Electricity generation is currently the biggest single source of CO2 emissions in the UK, responsible for approximately a third of total emissions.
CO2 from nuclear
Note that the figures shown on this page are for carbon dioxide emissions directly related to electricity generation and take no account of lifecycle emissions.
For nuclear power in particular there are carbon dioxide emissions related to construction of the power station and mining and processing of the uranium fuel.
An interesting assessment of these emissions is given in World warms to nuclear power by Dr Nigel Mortimer.
