International treaties frequently include definitions of relevant terms. Definitions of key terms can play an important role in facilitating and supporting treaty negotiations and are often critical for implementing a treaty after its ratification. The Compilation examines over 100 terms that may be relevant for the plastics treaty, offering examples of where those terms appear in other Multilateral Environmental Agreements, as well as the European Union, the Organisation for Economic Co-operation and Development (OECD), and other bodies such as the International Union of Pure and Applied Chemistry (IUPAC), the Group of Experts on the Scientific Aspects of Marine Environmental Protection (GESAMP) and the International Standardisation Organisation (ISO).
