Nuclear weapons and international efforts to control them have been at the core of SIPRI’s research since the founding of the institute. Our work includes looking at legal, political, technical and historical aspects of nuclear disarmament, arms control and non-proliferation, including the implementation and verification of relevant international treaties.
An important part of SIPRI's work on nuclear weapons is its world nuclear forces data, which reveals annual estimates on the number and types of nuclear weapons held around the world.
SIPRI is one of four institutes managing the EU Non-Proliferation and Disarmament Consortium, a group of research centres and think tanks that promotes the non-proliferation of weapons of mass destruction.
SIPRI follows the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), which is officially reviewed every 5 years.
