Overview
ISO 14021:2016/Amd 1:2021 is an important amendment to the international standard focused on environmental labels and declarations, specifically addressing self-declared environmental claims (Type II environmental labelling). This update incorporates critical guidance on carbon footprint and carbon neutrality to provide clear, standardized communication about greenhouse gas (GHG) emissions related to products.
Developed by ISO Technical Committee ISO/TC 207 and its Subcommittee SC 3 on Environmental Labelling, in collaboration with the European Committee for Standardization (CEN), this amendment ensures transparency and consistency in environmental claims. The standard guides organizations in accurately quantifying, reporting, and communicating carbon-related assertions - such as carbon footprint of a product and carbon neutral claims.
Key Topics
-
Carbon Footprint of a Product (CFP):
Defined as the total greenhouse gas emissions and removals associated with a product system, expressed in CO₂ equivalents. It is based on a life cycle assessment (LCA) of climate change impact, following the requirements of ISO 14067.
-
Partial Carbon Footprint of a Product:
Focuses on GHG emissions and removals from selected stages or processes within a product’s life cycle, allowing for more specific footprint information modules based on one or more processes.
-
Carbon Neutral Claims:
A product is considered carbon neutral if its total carbon footprint is zero or if emissions have been reduced to zero through verified offsetting mechanisms. Claimants must clearly specify which life cycle stages are accounted for, describe offsetting methods used, and provide transparent access to offset program details.
-
Quantification and Communication Methods:
Quantification of CFP and partial CFP must comply with ISO 14067, while communication should adhere to ISO 14026 principles for footprint information. This ensures credibility and prevents misleading or unqualified environmental claims.
-
Guidance on Claim Usage:
All carbon-related environmental claims must be specific, verifiable, and include qualifiers that explain emission reductions or offsetting strategies. General or unqualified claims of carbon neutrality are not permitted to maintain consumer trust and compliance with best practices.
Applications
ISO 14021:2016/Amd 1:2021 is widely applicable for:
-
Manufacturers and Product Developers:
To assess and communicate the carbon footprint of products, improving environmental responsibility and meeting regulatory or consumer demands for sustainability transparency.
-
Brand Owners and Retailers:
To verify environmental claims on labels, marketing materials, and declarations, fostering authenticity in carbon neutrality statements and enabling informed purchasing decisions.
-
Environmental Consultants and Auditors:
To support clients in preparing compliant environmental claims and ensuring proper documentation and communication per international standards.
-
Policy Makers and Regulators:
To establish consistent frameworks for environmental labelling laws and guidelines related to carbon footprint and neutrality claims in the marketplace.
-
Consumers and Advocacy Groups:
To better understand and trust carbon-related environmental information on products, aiding decisions that promote reduced climate impact.
