Editing Plastic production (mass) (section)

== Monitoring and Measurement ==
Monitoring plastic production involves compiling data from industrial reports, trade statistics, and material flow analyses. Scientific institutions and industry organizations track production volumes periodically, often on an annual basis, using standardized measurement conventions. Recent advances in trade-linked material flow analysis provide detailed insights into the complexities of the global plastics supply chain, enabling more accurate quantification of production volumes. These methods support the assessment of plastic production as a driver of environmental change and facilitate integration with other environmental monitoring frameworks.

Within the SIGNAL system, this phenomenon is treated as a defined environmental signal whose boundaries and measurement conventions are described below.
