Campaign overview

The International Campaign to Abolish Nuclear Weapons (ICAN) is a global campaign coalition working to mobilize people in all countries to inspire, persuade and pressure their governments to initiate and support negotiations for a treaty banning nuclear weapons. We call on states, international organizations, civil society organizations and other actors to:

  • Acknowledge that any use of nuclear weapons would cause catastrophic humanitarian and environmental harm.
  • Acknowledge that there is a universal humanitarian imperative to ban nuclear weapons, even for states that do not possess them.
  • Acknowledge that the nuclear-armed states have an obligation to eliminate their nuclear weapons completely.
  • Take immediate action to support a multilateral process of negotiations for a treaty banning nuclear weapons.

Our campaign brings together humanitarian, environmental, human rights, peace and development organizations in more than 90 countries to seize the historic opportunity that exists to outlaw and eliminate nuclear weapons. Prominent individuals such as anti-apartheid leader Desmond Tutu, the Dalai Lama, Yoko Ono and Martin Sheen have lent their support to the campaign.
