The Cartagena Protocol on Biosafety is an international agreement adopted in 2000 as part of the Convention on Biological Diversity. It specifically addresses the safe handling, transport, and use of living modified organisms (LMOs), commonly known as genetically modified (GM) organisms. While GM foods (A) are related, the protocol's scope is broader biosafety. Chemical weapons (B) and greenhouse gases (D) are covered by other treaties.
