14 May 2021 Share World leaders have a critical opportunity at the G7 and Pre-COP summits "to set a bold new direction" in the fight against climate change, six nuclear industry groups say in an open letter published today. The letter was signed by the heads of the Canadian Nuclear Association, Europe's Foratom, the Japan Atomic Industrial Forum, the USA's Nuclear Energy Institute, the UK's Nuclear Industry Association and World Nuclear Association - respectively, John Gorman, Yves Desbazeille, Shiro Arai, Maria Korsnick, Tom Greatrex and Sama Bilbao y León. Nuclear power is currently the biggest source of low-carbon electricity in developed economies and the second largest globally, but by 2040 more than 100 gigawatts of nuclear capacity is due to retire. Over the same period, global electricity demand is expected to increase by 50%. The choice policymakers face then is: risk "the single greatest loss of clean power in world history", or preserve and expand nuclear energy's proven contribution to curbing emissions.
