Lifecycle Carbon Intensity of PET Bottles Across Production Stages (g CO2e per Bottle)

This chart visualizes the estimated carbon intensity (in grams CO2 equivalent per bottle) of a standard 500 mL PET plastic bottle across seven key lifecycle stages: Concept, Polymer Production, Preform Molding, Bottle Blow Molding, Filling & Capping, Distribution, and Retail Readiness. The dataset is synthetic but grounded in typical industry patterns: polymer production contributes a large initial emissions burden due to feedstock processing and energy use; molding stages add moderate process emissions; filling and capping include both hygienic and thermal processes; distribution often adds a pronounced emissions peak because of transportation energy and refrigeration where applicable; retail readiness slightly decreases per-bottle emissions due to aggregation efficiencies and economies of scale. Interpreting the line, note the steep rise from Concept to Polymer Production, reflecting the material-intense nature of PET manufacturing. A plateau through molding stages indicates process-controlled incremental emissions. The sample dataset shows a secondary peak at Distribution, which underscores the importance of logistics optimization, modal shifts to lower-carbon transport, and increased vehicle fill rates. Retail Readiness shows a mild decline per bottle as distribution efficiencies and packaging consolidation reduce the per-unit footprint. Use cases for this visualization include lifecycle assessments, supply chain decarbonization planning, and comparative scenario modeling (e.g., recycled content, renewable energy use in production, or localizing supply chains). Planners can overlay interventions—such as increasing recycled PET share or switching to electric fleets—to simulate potential emission reductions. While values here are illustrative, the pattern highlights where interventions yield the largest marginal gains: upstream material choices and downstream logistics. For precise decision-making, replace synthetic values with measured data from suppliers, transport providers, and production facilities to quantify real-world savings and prioritize investments. Additional analyses can segment data by bottle size, recycled content percentage, regional energy mix, and transport mode to provide tailored mitigation roadmaps for stakeholders across the value chain.
