What Is the A/CPPNM and Why Is It Important?

| Mar. 28, 2022

This week in Vienna, experts from the Nuclear Threat Initiative are joining government officials and experts from international organizations, non-governmental organizations, academia, and the nuclear industry for the first-ever review of the only legally binding treaty on nuclear security—the amended Convention on the Physical Protection of Nuclear Materials (A/CPPNM). The Conference of Parties to the A/CPPNMfrom March 28-April 1, 2022 at the International Atomic Energy Agency (IAEA), will review the implementation of the A/CPPNM, assess its adequacy, and consider current threats to the security of nuclear materials.

The gathering comes at a pivotal moment for strengthening norms and laws that promote strong security at nuclear facilities around the world. High-level attention to this issue has waned in recent years, progress to reduce risks has slowed, and cooperation between the countries that face the greatest risks has faded. Additionally, Russia’s recent attacks on Ukrainian nuclear facilities run contrary to international law, shatter existing norms, and raise important questions around the future of international nuclear security cooperation.
