ISO 14067 provides a standardized methodology for calculating the CFP, ensuring consistency and comparability between products and organizations. Assessing a product’s GHG emissions should include ISO 14040 and ISO 14044’s life cycle analysis techniques.
Crucially, using ISO 14067 to calculate the CFP can ensure that product life cycle analysis is complete and all relevant product information considered.
There are two complementary approaches. An iterative approach provides consistency in the results and refines them until the best results are obtained. A scientific approach includes, where possible, physical, chemical, biological and other information and data for product life cycle analysis.
Organizations must show that results are consistent, accurate and, if the outcome of the analysis is communicated externally, transparent, so interested third parties can be confident in the results.
