Greenhouse gases — Quantification methods and requirements for product carbon footprint — Rare earth permanent magnet materials
1 Scope
This document specifies the goal and scope definition, life cycle inventory analysis, impact assessment, interpretation, and product carbon footprint report for quantifying the carbon footprint of rare earth permanent magnet materials.
This document applies to the quantification of the product carbon footprint of rare earth permanent magnet materials. The results can serve as references for various applications such as product carbon footprint performance evaluation, product carbon footprint information disclosure, and environmental information disclosure. It applies to a single environmental impact category: climate change.
NOTE: Carbon offsetting is not within the scope of product carbon footprint quantification.
This document is not applicable for evaluating other potential environmental impacts generated during the product life cycle, nor is it applicable for evaluating potential social and economic impacts that may occur during the product life cycle.
