The Parliamentary Office of Science and Technology, which is Parliament's in-house source of independent, balanced and accessible analysis of public policy issues related to science and technology, has produced a briefing note setting out lifecycle carbon emissions of electricity generating technologies. This briefing note states that from a series of peer-reviewed studies, most estimates of nuclear lifecycle emissions internationally are below 26 grams of carbon dioxide equivalent per kilowatt-hour of electricity generated. Some studies referenced in the note place these values much lower even than 26gCO2eq/kWh, with cited UK nuclear generation estimated to be between 5.5 and 7gCO2eq/kWh. These figures are comparable to those for offshore wind generation, stated to be between 5.2 and 13gCO2eq/kWh. Nuclear generation has been a proven, reliable source of electricity generation in the UK and worldwide for decades. The full note on lifecycle carbon emissions is available online at the following address:
