Nuclear weapons have been one of the core areas of SIPRI’s research programme since the founding of the institute. Together with biological and chemical weapons, SIPRI promotes their non-proliferation and disarmament. Our work includes looking at legal, political, technical and historical aspects of biological, chemical and nuclear warfare prevention, including the verification of weapons and the implementation of 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.
Additionally, SIPRI is one of four institutes managing the EU Nonproliferation 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.
