Overview
IEC TR 62725:2013 - "Analysis of quantification methodologies of greenhouse gas emissions for electrical and electronic products and systems" is a Technical Report from the International Electrotechnical Commission (IEC). It provides guidance to understand, compare and evaluate methodologies for quantifying the carbon footprint (CFP) and greenhouse gas (GHG) emissions of electrical and electronic (EE) products using life‑cycle thinking. The report is industry‑focused, based on a comparative study of existing international CFP and LCA approaches, and is applicable to new and modified EE products (including reconditioned or upgraded items).
Key topics and technical requirements
IEC TR 62725 organizes practical guidance around LCA‑based CFP studies and highlights critical methodological elements:
- Life Cycle Thinking (LCT) and alignment with LCA principles for cradle‑to‑grave assessment.
- Goal and scope definition, including clear unit of analysis and intended use of results.
- Unit of analysis and system boundary selection (life‑cycle stages, process maps, attributional vs consequential approaches, time boundaries, GHG sources/sinks).
- Data collection & quality assessment: primary vs secondary data, applicable databases, and data quality criteria.
- Quantification framework: calculation approaches, allocation methods, emission factors per life‑cycle stage.
- Cut‑off criteria and trial estimation for deciding excluded flows.
- Uncertainty analysis, maintenance/use scenarios and end‑of‑life treatment.
- Documentation, communication and verification: CFP reporting, Product Category Rules (PCRs), and options for third‑party assurance.
- Annexes with database examples, comparative study results, PCR examples and guidance on uncertainty.
Practical applications
IEC TR 62725 is practical for organizations that need to measure or communicate product‑level climate impacts:
- Supporting early eco‑design decisions to reduce product GHG profiles.
- Developing product carbon footprint (PCF) declarations, ecolabels or sustainability marketing claims.
- Informing supply chain GHG reporting, procurement specifications and supplier engagement.
- Harmonizing methods for comparative studies between products or design options.
- Preparing documentation for verification and assurance against CFP/LCA standards.
Who should use this standard
- Product designers and environmental engineers in the EE industry
- LCA practitioners and sustainability consultants
- Environmental compliance and CSR teams
- Procurement, supply‑chain and product‑stewardship managers
- Policy makers and certification bodies evaluating product‑level GHG methods
Related standards
- ISO 14067 (Product carbon footprint - principles, requirements and guidelines)
- ISO 14040 / ISO 14044 (Life Cycle Assessment standards)
- Product Category Rules (PCRs) and sector‑specific guidance referenced in the TR
IEC TR 62725 helps align CFP studies for electrical and electronic products with accepted LCA practices, offering practical, industry‑specific guidance to improve consistency, transparency and credibility of product GHG quantification.
