Structure and Elements of International Legal Instruments

The document compares substantive, hybrid, and framework conventions, arguing that a substantive treaty with clear national obligations is necessary for the future plastics treaty to avoid delays in urgent action.

• The document identifies three primary treaty structures: substantive conventions, which are specific and unambiguous in obligations; framework conventions, which are typically general and broad and leave specific obligations to future protocols; and hybrid conventions, which combine elements of both.
• Framework conventions often achieve high participation because they lack meaningful obligations, but they can significantly delay the implementation of concrete obligations.
• The author recommends that the future plastics treaty be a substantive treaty with clear national obligations, explicitly advising against a framework convention as it would "significantly delay urgent action".
• The document highlights the importance of annexes for treaty flexibility, noting that amending them is usually the easiest way to strengthen a treaty over time, provided the treaty first contains concrete obligations.
• Analysis of past instruments shows that the Montreal Protocol is regarded as highly successful because it includes binding obligations with enforcement and financial mechanisms, whereas the Kyoto Protocol failed to stop global emissions increases because major emitting Parties did not join or were not required to reduce emissions.
