This dictionary focuses on decision quality: each term includes what it means, where it can mislead, and how to apply it in real purchasing or policy choices.
Each entry includes definition, trade-off lens, and published date to show how the concept evolved.

Published: May 15, 2026
A chain-of-custody model where recycled or biobased feedstock is tracked through a production system in proportion to output claims, rather than physical batch segregation.
Decision tip: confirm which standard applies (e.g. ISCC PLUS, RSB) and whether the claim is product-level or site-level.
Published: May 15, 2026
A verified, life-cycle-based summary of environmental impacts for a product or material, usually following ISO 14025 and relevant product category rules (PCR).
Decision tip: compare functional units, system boundaries, and data age—do not rank materials from headline numbers alone.
Published: May 15, 2026
Policy frameworks that shift end-of-life collection, sorting, and financing obligations toward producers and importers, often affecting packaging design and labeling requirements.
Decision tip: map obligations by market and material class; EPR fees can change incentives faster than consumer-facing green labels.
Published: Jan 6, 2025
A material option with lower life-cycle greenhouse gas intensity than a conventional baseline, considering production energy, transport, durability, and end-of-life.
Decision tip: compare functional equivalence (same performance lifespan) rather than comparing raw kg-to-kg numbers only.
Published: Nov 30, 2024
Indicates intentional exclusion of per- and polyfluoroalkyl substances, often used in grease/water-resistant products. Scope and detection limits matter.
Decision tip: request test method, threshold, and whether replacement chemistry was assessed.
Published: Aug 21, 2024
Compostability depends on test standard and operating conditions. Industrial composting and home composting have very different thresholds.
Decision tip: only treat as compostable if your local system accepts that specific certified format.
Published: May 9, 2024
Derived partly or fully from biomass (corn, sugarcane, cellulose, etc.). Biobased does not automatically mean biodegradable.
Decision tip: separate feedstock origin, land-use impact, and end-of-life pathway before choosing.
Published: Feb 18, 2024
Percentage of material sourced from recovered waste streams. Post-consumer content generally indicates stronger circularity impact than pre-consumer scrap.
Decision tip: ask for third-party verification (GRS/RCS or equivalent) and clarify mass-balance vs physical segregation.
