Abstract Emergy analysis (EmA) is the quantitative sustainability method that analyses materials, energy resources, goods, or services under a common unit of solar emergy (seJ). Meanwhile, life cycle assessment (LCA) one popular tools to evaluate environmental impacts. Both methods have been widely used in various applications, hence, idea co‐jointing these two has increasing optimize assessment's inclusivity. However, existing integrated LCA–EmA are applied segmentally with minimal data integration, which limited potential co‐benefits accounting. This research proposes more comprehensive integration between LCA and EmA, known as (LCEmA). The process fully integrated, detailed methodological approach presented demonstrate process. Diaper manufacturing selected case study validate functionality proposed LCEmA approach. inclusion foreground background offered considers backend processes such electricity generation for activities. shifted hotspot from raw material extraction demonstrates can perform promising alternative methods.

Proton-exchange membrane fuel cells (PEMFCs) are highly regarded as a promising technology for renewable energy generation; however, the environmental burden in their life cycle is subject of concern. This study aimed to assess impact producing 1 kW PEMFC by well-detailed cradle-to-gate evaluation, using mid-point and end-point assessment methods. The impacts related extraction raw materials, consumption energy, transportation processes. Mid-point analysis shows that materials processing have significant share some impacts, including freshwater eutrophication, human carcinogenic toxicity, terrestrial acidification. On other hand, consumed cell production plays role categories fossil resource depletion global warming. highest attributed health (0.000866 DALY), followed damage ecosystems (1.04 × 10−6 species/yr) resources (USD2013 6.16844). Normalization results further strengthen importance necessity solve problems regarding toxicity. this work can provide directions toward enhancing sustainability present case adopting holistic approach looking across technology.
