In signing and ratifying the Comprehensive
Nuclear-Test-Ban Treaty (CTBT), a State joins a group of
like-minded countries that are dedicated to strengthening
the international nuclear non-proliferation and
Banning nuclear explosions of any kind is an important step towards making the world a safer place.
• The CTBT is essential for nuclear non-proliferation since it limits the ability of countries that do not have nuclear weapons to develop these weapons.
• The CTBT is also essential for nuclear disarmament since it curbs the development of new types and new designs of nuclear weapons.
• The CTBT is crucial in a world in which we see the resurgence of nuclear energy. A legally binding Treaty banning nuclear test explosions provide a clear and visible barrier between prohibited and permitted nuclear activities.
• The CTBT is a strong confidence- and security building measure – internationally, regionally and bilaterally.
• The CTBT also protects against the devastating effects of nuclear testing on human health and the environment.

Although the CTBT has not yet entered into force, it has already helped to create a de facto international norm. As of April 2012, 183 countries have signed the Treaty, of which 157 have also ratified it. Over 2000 nuclear test explosions were conducted between 1945 and 1996; about half a dozen tests have been conducted since 1996.
