{{SignalTerm|type=DS|id=DS-00070|label=Plastic production (mass)}} refers to the total global quantity of synthetic polymer materials manufactured for commercial and industrial use. This phenomenon represents a significant driver within the human domain, influencing environmental systems through its role as a pressure or stressor. The production of plastics has increased substantially over recent decades, reflecting growing demand across multiple sectors including packaging, construction, automotive, and consumer goods. Understanding the scale and dynamics of plastic production is essential for assessing its environmental impacts and for contextualizing related damage signals such as plastic waste leakage into natural ecosystems. Plastic production is commonly measured in metric tonnes (t), providing a standardized unit for global assessments.

== Geographic / System Context ==
Plastic production is a global phenomenon, with manufacturing facilities distributed across diverse geographic regions. Major production hubs are concentrated in industrialized and emerging economies, reflecting patterns of economic development, resource availability, and trade networks. The global plastic production system is interconnected through complex supply chains that span continents, linking raw material extraction, polymer synthesis, product manufacturing, and consumption. This geographic distribution influences the environmental footprint of plastic production, including associated emissions and waste generation, and shapes regional and global environmental pressures.

== 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.

== Signal Definition ==
The Plastic production (mass) signal quantifies the total mass of synthetic polymer materials produced globally over a defined time period. It captures the aggregate quantity of plastics manufactured, expressed in metric tonnes (t), representing a primary human-induced pressure within environmental systems. This signal is derived from the Observable Type 'Plastic production (mass)' and serves as an indicator of the scale of plastic-related human activities affecting the environment.

== Boundary Conditions ==
Boundary inclusions encompass all synthetic polymer materials produced for commercial, industrial, and consumer applications worldwide, including thermoplastics, thermosetting plastics, and elastomers. Boundary exclusions include biodegradable polymers produced in quantities not classified as conventional plastics, recycled plastic materials not accounted as new production, and plastic additives or fillers measured separately. The signal excludes plastic waste generation, leakage, or environmental accumulation, focusing solely on production volumes.

== Aggregation Semantics ==
Geographically, plastic production data are aggregated at global and regional scales, reflecting the distribution of manufacturing activities and trade flows. Temporal aggregation is periodic, typically annual, enabling trend analysis and comparison across time intervals. Cross-signal aggregation involves integration with related environmental signals such as plastic waste leakage to the marine environment, facilitating comprehensive assessments of plastic's environmental impacts. Aggregation notes emphasize the importance of consistent units (metric tonnes) and standardized reporting periods to maintain data comparability.

== Observational Status ==
Current monitoring of plastic production relies on periodic data collection from industrial and trade sources, with ongoing efforts to refine measurement methodologies through material flow analyses. Data coverage is global but may vary in resolution and completeness depending on regional reporting practices. Future SIGNAL releases may incorporate enhanced data integration, improved temporal resolution, and linkage with downstream environmental impact signals to provide a more holistic understanding of plastic production's role within the Earth system.
