IEC TR 62921:2016(E) provides specific guidance for the use of streamlining techniques that minimize cost and resources needed to complete greenhouse gas emissions quantifications. In addition, the product category rules (PCR) section of this Technical Report recommends "state-of-the-art" process and data assumptions in order to reduce uncertainty. Lastly, this Technical Report provides an example of how a calculation could be performed.

Overview

IEC TR 62921:2016 - Quantification methodology for greenhouse gas emissions for computers and monitors - is a Technical Report from the International Electrotechnical Commission (IEC) that provides guidance for calculating product carbon footprints (PCF) and greenhouse gas (GHG) emissions specifically for computers and monitors. The report focuses on streamlined CFP (product carbon footprint) techniques to reduce cost and resource burdens, recommends state‑of‑the‑art process and data assumptions to lower uncertainty, and includes a worked example of a calculation.

Key Topics

Streamlined CFP approaches: Practical methods to simplify data collection and processing while maintaining comparability with comprehensive life cycle assessments (LCA).

Product category rules (PCR): Recommended rules and assumptions tailored for computers and monitors to harmonize scope, allocation and data use.

Life cycle stages: Guidance on which stages to include or exclude (production, assembly, distribution, use, end-of-life) and how to treat each stage for ICT products.

Data quality and uncertainty: Recommendations on primary vs. secondary data, aggregated datasets, and strategies to reduce uncertainty in emissions estimates.

State‑of‑the‑art calculations: Component‑level guidance (chassis, PWBs, ICs, displays, storage devices, PSUs, batteries, packaging) with considerations for input data.

Databases and references: Examples of relevant LCA/economic databases and energy consumption sources (e.g., Ecoinvent, GaBi, ELCD) presented in informative annexes.

Example calculation: Annex material includes a generic streamlined CFP process and an example calculation for a notebook computer.

Applications

IEC TR 62921 is practical for organizations that need credible, cost‑effective GHG quantification for computers and monitors:

Manufacturers and product designers use it to estimate the carbon footprint of new and existing models for design trade‑offs and supply‑chain decisions.

Sustainability and LCA practitioners apply the streamlined methods and PCR recommendations to generate consistent, comparable CFPs.

Procurement and corporate reporting teams use the methodology for supplier engagement, carbon reporting, and product‑level environmental disclosure.

Regulators, ecolabeling and verification bodies can adopt the PCRs and documented assumptions to assess conformity and reduce variability in claims.
