However, the group’s entire activities, in Mining, Front End, and Back End of the cycle, participate in the value chain of nuclear power generation, which is a source of reliable, controllable, and decarbonized energy necessary for the energy transition. These activities are therefore essential for the operation of the nuclear sector, itself eligible for the Taxonomy according to the European Union amending delegated act 2022/1214.
