Which of the following actions best reflects a compliant approach to address these challenges according to ISO 14067:2018?

Accepted Answer

EcoChic should apply allocation rules based on the economic value of the cotton relative to the other crops produced by the cooperative, and should include consumer washing and drying habits within the system boundary if these activities represent a significant portion of the product's life cycle emissions.

Question 30

EcoSolutions Inc., a manufacturer of biodegradable packaging, is seeking ISO 14067:2018 certification for its new line of compostable food containers. During the carbon footprint assessment, the company\'s sustainability team discovers that the transportation of raw materials from a specific supplier contributes significantly to the overall GHG emissions. To improve the perceived environmental performance of their product and attract environmentally conscious consumers, the team decides to exclude the emissions associated with this particular transportation phase from the system boundary, arguing that it is a minor contributor compared to the manufacturing process itself, even though it accounts for 15% of the total emissions. The company proceeds with the certification process without disclosing this exclusion in their documentation.

Which principle of ISO 14067:2018 has EcoSolutions Inc. violated, and why is this action considered non-compliant?

Accepted Answer

The company has violated the transparency and completeness principles of ISO 14067:2018 because intentionally excluding a significant emission source to present a lower carbon footprint undermines the credibility and comparability of the CFP result.
