International Campaign to Abolish Nuclear Weapons (ICAN)
The International Campaign to Abolish Nuclear Weapons (ICAN) is a coalition of non-governmental organisations in one hundred countries promoting adherence to and implementation of the United Nations Treaty on the Prohibition of Nuclear Weapons (TPNW).
ICAN works to promote adherence to and full implementation of TPNW. The campaign helped bring about this treaty. ICAN was launched in 2007 and counts 607 partner organizations in 106 countries as of 2021.
The campaign received the 2017 Nobel Peace Prize “for its work to draw attention to the catastrophic humanitarian consequences of any use of nuclear weapons and for its ground-breaking efforts to achieve a treaty-based prohibition of such weapons.”
