Swiss Parliament Lifts Nuclear Ban, Triggers Referendum Campaign June 20

Switzerland’s National Council voted to lift the ban on new nuclear power plants on June 19, 2026, reversing a long-standing policy. The decision came from a conservative coalition of the SVP, FDP, and centrist members who argue nuclear power is essential for climate goals and electricity supply. A left-green alliance backed by parts of the center party is already campaigning for a referendum to overturn the decision.

How Parliament Voted on Nuclear Power

The National Council approved lifting the technology ban on new nuclear power plants before the final summer session ended on June 20. A conservative majority pushed the bill through despite opposition from the Socialist Party, Green Party, and some centrist members. The decision reverses a popular vote on phasing out nuclear power that took place years earlier.

Why the Left Opposes the Change

Socialist Co-President Mattea Meyer called the decision a win for the nuclear lobby and rejected the technology as too dangerous and expensive. Green Party leader Greta Gysin argued that history shows nuclear power is too big a challenge for humanity. She said the focus should shift to expanding renewable energy instead. Center Party spokesperson Stefan Müller-Altermatt also criticized the bill as unbalanced, noting that nothing is known about financing and safety of new plants.

Why Conservatives Back Nuclear Energy

The conservative majority argues that nuclear power is the only realistic option to meet long-term electricity demand and climate goals. SVP member Christian Imark stated that Switzerland needs existing nuclear plants to operate longer and probably new ones as well. FDP member Damien Cottier warned against closing off options, saying Switzerland must remain pragmatic and realistic to produce enough electricity in the coming decades.

The Referendum Fight Begins

The referendum campaign against the nuclear decision has already started, even before the National Council’s final approval. A left-green alliance supported by parts of the centrist party will lead the fight. Under Swiss law, the public will have the final say on whether new nuclear power stations can be built. The outcome of the referendum will determine if Switzerland reverses its decades-long nuclear phase-out policy.

Final Thoughts

Switzerland’s Parliament voted to end the nuclear ban, but voters will decide the issue through referendum. The battle over energy policy will now shift from Parliament to the ballot box.
