Greenpeace has criticized EDF, a major French energy company, for its ongoing business relationship with Russia, particularly in the nuclear sector. On September 15, the environmental organization sent a formal letter to EDF under the "duty of vigilance" law, which requires companies to monitor and address potential human rights and environmental risks in their supply chains. Greenpeace accuses EDF of maintaining commercial ties with Rosatom, the Russian state nuclear corporation, four years after Russia's invasion of Ukraine. The NGO argues that EDF continues to send spent nuclear fuel—known as used radioactive material (URT)—to the Seversk site in Siberia, where it is processed. The Seversk facility, operated by Rosatom, has been described as outdated by France’s High Committee for Transparency and Information on Nuclear Safety (HCTISN). Since its opening in 1953, the plant has been involved in several accidents that led to radioactive leaks into the environment. The most severe incident occurred in 1993, when contamination spread up to 28 kilometers from the site. Greenpeace France warns that these operations pose serious risks to the environment, public health, and the safety of workers and local residents. It also claims that EDF’s commercial ties with Russia may indirectly fund atrocities committed in Ukraine, including the illegal occupation of the Zaporijia nuclear power plant. Greenpeace further highlights that EDF has not included its nuclear dealings with Russia in its 2024 and 2025 vigilance plans, which are meant to identify and address potential risks. Roger Spautz, a campaign manager for energy transition and nuclear issues at Greenpeace France, argues that EDF cannot promote its uranium cycle as part of a circular economy while ignoring the environmental and human costs, especially when these occur abroad. In May 2026, Greenpeace had already raised concerns about the lack of European sanctions targeting Russian nuclear activities, even as oil and gas imports from Russia were banned. In addition to the shipment of spent nuclear fuel to Siberia, France imports natural uranium from Kazakhstan and Uzbekistan, some of which passes through logistics networks linked to Russia. This highlights the complex and interconnected nature of global nuclear supply chains, raising questions about the extent to which European countries are indirectly supporting Russian nuclear operations.
