IEA: Nuke retirements could lead to 4 billion metric tons of extra CO2 emissions

A report released today by the International Energy Agency (IEA) warns world leaders that—without support for new nuclear power or lifetime extensions for existing nuclear power plants—the world’s climate goals are at risk.

“The lack of further lifetime extensions of existing nuclear plants and new projects could result in an additional four billion tonnes of CO₂ emissions,” a press release from the IEA noted.

The report is the IEA’s first report on nuclear power in two decades, and it paints a picture of low-carbon power being lost through attrition (due to the retirement of aging plants) or due to economics (extremely cheap natural gas as well as wind and solar undercutting more expensive nuclear power for years in some regions).
