We do not need nuclear power.

Welcome to the Clamshell Alliance website. The Clamshell opposes nuclear power, a false solution to the climate emergency. The New England-based Clamshell Alliance inspired the national anti-nuclear movement in the 1970s. The Clamshell experience, which drew on the wisdom of generations of struggles, speaks to the world’s current crises. We persist in saying “No Nukes” as we all continue to strive for justice, joyfully, on many fronts.
