Analysis of the Definition and Scope of Plastic in the Context of the Global Plastics Treaty

Plastic pollution is a hotspot in current environmental governance, with significant attention directed towards the global plastics treaty mandated by the United Nations Environment Assembly (UNEA). As a key term of the treaty, the definition and particularly the scope of plastic, is critical to how the treaty addresses plastic pollution. However, discussions on this issue remain inadequate. This perspective analyzes the definition and scope of plastic in the context of the global plastics treaty. It first introduces the process of the ongoing negotiation of the Intergovernmental Negotiating Committee (INC). It subsequently discusses the processing and mechanical properties within the definition of plastic, the distinction between plastic and resin, and biodegradable plastics. Finally, it posits that the treaty should take the following issues into consider: (1) it should be based on broader participation and consensus; (2) as an international legally binding instrument, it should include a standalone provision of definition; (3) it should scientifically and accurately define plastic, clarifying that fibers and rubbers are not included, and distinguishing between plastic and resin. Only by ensuring that appropriate entities are regulated without intentionally broadening the scope could the treaty genuinely advance international cooperation in addressing plastic pollution.
