Building a future
beyond nuclear fear.
We are a hub where thought leaders, innovators, campaigners, and activists convene and take action to move us closer to a world free from nuclear threats.
Ploughshares is a relentless force committed to eliminating the threat of nuclear weapons. As the largest foundation singularly focused on reducing this danger, we grow and amplify the impact of the most effective advocates and organizations in the world through critical funding and trusted field building support.
Nuclear war affects everyone. We raise much-needed awareness to the perils of nuclear weapons development, testing, and use.
Women Transforming Global Security (WTGS) represents an unprecedented collaboration between The Elders, Ploughshares, and Horizon 2045—organizations united in their commitment to women’s leadership and breakthrough thinking at the intersection of global challenges.
WTGS unites the expertise of former heads of state, senior policymakers, and emerging leaders to advance feminist principles of collaborative problem-solving, long-term thinking, and collective intelligence in service of human and planetary security.
