Overview

EN ISO 22526-3:2021 - Plastics - Carbon and environmental footprint of biobased plastics - Part 3: Process carbon footprint (P‑CFP) - specifies requirements and guidelines for quantifying and reporting the process carbon footprint of biobased plastics. Aligned with ISO 14067 and consistent with life cycle assessment standards (ISO 14040 / ISO 14044), this document defines how to perform a partial carbon footprint study (cradle-to-gate perspective) for plastic materials. The standard applies whether results are intended for internal use or public reporting. Offsetting is outside the scope.

Key Topics and Requirements

• Scope and purpose: Defines P‑CFP as a partial carbon footprint of a bioplastic product and sets rules for quantification and reporting.
• Principles: Emphasizes life cycle perspective, cradle-to-gate boundaries, use of a functional unit, iterative study design, and priority of approaches to data and modelling.
• Quality criteria: Requirements for relevance, completeness, consistency, coherence, accuracy and transparency, and avoidance of double-counting.
• Methodology for CFP quantification:
  • Use of product category rules (CFP‑PCR) where applicable.
  • Clear goal and scope definition for each P‑CFP study.
  • Life cycle inventory (LCI) requirements specific to biobased plastics, including treatment of biogenic carbon flows.
  • Impact assessment aligned with ISO 14067 methods for greenhouse gas (GHG) quantification.
  • Iterative interpretation to address data gaps and uncertainties.
• Reporting: Mandatory and optional information to ensure transparency and credibility when P‑CFP results are reported (including GHG values and methodological choices).
• Critical review: Guidance on independent review processes to support credibility for externally communicated results.

Applications and Users

This standard is intended for:

• Plastics manufacturers and converters producing or specifying biobased plastics.
• LCA practitioners and sustainability consultants conducting partial carbon footprint or product carbon footprint studies.
• Product managers and procurement teams assessing carbon impacts of materials.
• Regulatory bodies, ecolabel developers, and auditors requiring a standardized approach to P‑CFP of biobased plastics. Practical uses include internal environmental performance tracking, supply‑chain reporting, PCR development, and comparative assessments of biobased vs. fossil‑based materials.

ISO 22526-3:2020(E)
Introduction
Increased use of biomass resources for manufacturing plastic products can be effective in reducing
global warming and the depletion of fossil resources.
Current plastic products are composed of biobased synthetic polymers, fossil-based synthetic polymers,
natural polymers and additives that can include biobased materials.
Biobased plastics refer to plastics that contain materials wholly or partly of biogenic origin.
