We educate and advocate for a just and peaceful world, one that is free of nuclear weapons.
Founded in 1982, we are a non-profit, non-partisan 501C(3), with consultative status to the United Nations
Economic and Social Council, recognized by the United Nations as a Peace Messenger Organization.
Based in Santa Barbara and New York, we work on advancing the Treaty on the Prohibition of Nuclear Weapons and other nuclear disarmament, nuclear justice, and peace initiatives.
RECENT EVENTS
“The clouds that parted following the end of the Cold War are gathering once more. We have been extraordinarily lucky so far. But luck is not a strategy. Nor is it a shield from geopolitical tensions boiling over into nuclear conflict. Today, humanity is just one misunderstanding, one miscalculation away from nuclear annihilation.”
António Guterres, Secretary-General of the United Nations
Nuclear Non-Proliferation Treaty 10th Review Conference, August 1, 2022

WHAT IS THE TPNW?
The Treaty on the Prohibition of Nuclear Weapons (TPNW) is a historic international agreement among states concerned about the welfare of humanity. The treaty prohibits the possession, development, deployment, use, and threat of use of nuclear weapons. The TPNW also contains a robust framework for assisting victims of nuclear weapons and remediating contaminated environments. It entered into force on January 22, 2021 and the First Meeting of States Parties was held in Vienna, Austria on June 21-23, 2022… Read More
WHY IT MATTERS
Nuclear weapons threaten everything we have ever known, everything we love. They threaten the existence of human civilization and even of humanity itself. We must get rid of nuclear weapons before they get rid of us.
WHAT WE DO
With the TPNW in force, we work with states and NGO colleagues and partners, like ICAN, on strengthening the treaty, from getting more states to join it, to implementation of provisions to address past humanitarian consequences.
DID YOU KNOW?
There are over 12,000 nuclear warheads in the world.
Most of them are 10 to 100 times more powerful than the Hiroshima bomb.
All of the nuclear weapons states are modernizing their nuclear weapons arsenals.
The US plans up to $2 trillion on its nuclear arsenal modernization.
