[en] On 8 May 2016, the Amendment to the Convention on the Physical Protection of Nuclear Material (CPPNM) finally entered into force, almost eleven years after its adoption. The world will be a more secure place as a result of the commitments that States party to the Amendment have made. The Amendment establishes legally binding commitments for countries to protect nuclear facilities as well as nuclear material in domestic use, storage and transport. Under the Amendment, countries are required to establish appropriate physical protection regimes for nuclear material. They also take on new obligations to share information on sabotage, including on credible threats of sabotage. The entry into force of the Amendment demonstrates the international community’s resolve to act together to strengthen nuclear security globally. It also helps reduce the risk of an attack involving nuclear material, which could have catastrophic consequences.
