What work does Nobel Peace-winning organisation ICAN do?

Founded in 2007, the International Campaign to Abolish Nuclear Weapons (ICAN) "promotes adherence to and implementation of United Nations' Treaty on the Prohibition of Nuclear Weapons". Headquartered in Geneva, it comprises 468 NGOs across 101 countries. ICAN, working with the Red Cross, has been a driving force behind 122 UN member states acceding to the Treaty in July 2017.
