IEC 62125:2019 provides methodologies addressing environmental evaluation and communication related to cables in normal use. It includes an environmental checklist for power cables, the method for life cycle assessment (LCA) and a methodology for conductor size optimization. The results obtained by applying such methodologies can be used for external communication. Environmental communication can also include other topics, such as material declaration.
