Weapons proliferation

We're working around the world to promote and implement the UK Government's policies on nuclear weapons, chemical and biological weapons, conventional weapons, export controls and ambition for an arms trade treaty.

How is the UK preventing the spread of weapons?

We work closely with the Department for Business, Enterprise and Regulatory Reform (BERR) and the Ministry of Defence (MOD) and our international partners to tackle this threat.

The UK has committed up to US$750m over 10 years through our Global Threat Reduction Programme for projects which:

improve the security of fissile materials, dangerous biological agents and chemical weapon stocks
reduce the number of sites containing radioactive material
work towards closure of reactors still producing plutonium
improve nuclear safety, to reduce the risk of further Chernobyl-type incidents
construct facilities for destroying chemical weapons stocks
provide sustainable employment for former weapon scientists whose expertise could be misused.

The UK is currently supporting projects to:

dismantle nuclear submarines in North-West Russia and make safe their spent nuclear fuel
dispose of 34 tonnes of plutonium in Russia
destroy Russia's stocks of chemical weapons (a total of 40,000 tonnes)
create sustainable employment for former Soviet weapons scientists.

International cooperation

Inspections by organisations such as International Atomic Energy Agency (IAEA) and the Organisation for the Prevention of Chemical Weapons (OPCW) help to enforce arms control.

Chemical and biological weapons

We're working to enforce the ban on chemical and biological weapons through international treaties and conventions.

Nuclear weapons

We're working to counter the continued threat of the proliferation of nuclear weapons. The UK retains a minimum nuclear deterrent.

Controlling the export of weapons

We're working to improve the international standard of export controls for weapons and the technology and material required to develop them.

Arms Trade Treaty

The UK supports a global Arms Trade Treaty ATT to curb the irresponsible trade and transfer of arms that are used to undermine stability, democracy, development and human rights.

Conventional weapons

We're working closely with other countries and international organisations such as the UN to develop an arms trade treaty to control the proliferation of conventional weapons.
