Summary of "Emerging technologies upscaling: a framework for matching LCA practices with upscaling archetypes."


Purpose: Society asks engineers and designers, though sustainability targets, to be highly concerned with socio-technical and environmental consequences generated by the technology they develop or use in products. Regarding technology upscaling, we proposed in previous research five related archetypes in engineering: upsizing, mass-producing, deploying, integrating a complex system, and down-limiting (Riondet et al., 2022). However, these five facets of the upscaling of technology are not explicitly associated with LCA practices. More precisely, usual upscaling technology LCA guidelines mainly focus only on the two first archetypes. Clarifying LCA approaches available in the literature is, therefore, necessary to match LCA practices with the five upscaling archetypes. Methods: This research paper is based on the characterization framework for upscaling assessment presented in previous research, completed by an LCA practices literature review in terms of addressed questions, theoretical basement, required expertise, and applicability issues. Then, this characterization of available LCA approaches and their applicability is confronted concerning a given goal of upscaling environmental assessments. The sorted references have been characterized in terms of "engineering field" to identify whether any guidelines they provide are generic or attached to a specific discipline or a type of product. Results: This literature review produced three main results: first, fifteen LCA modes are characterized in terms of definition, addressed questions, studied objects, the expertise required, scope specificities, and structuring references. Second, guidelines have been extracted from selected case studies or reviews from different engineering fields (e.g. chemistry, energy, transport). This constitutes a generic LCA framework to environmentally assess each upscaling archetype. Third, the LCA references are ranked by the related engineering fields. Finally, the challenges of extending these three results are discussed, especially concerning the emergence of new LCA modes in reaction to specific needs for environmental assessments (e.g. transition LCA) and in an eco-design perspective based on environmental upscaling assessment. Conclusions: The proposed synthesis, guidelines, and representation provide practical recommendations for LCA practitioners considering the upscaling of emerging technologies. This overview can be completed with currently adopted LCA practices in literature and companies. This work paves the way for two kinds of further research: first, to refine theoretical and practical LCA modes compatibility based on developments by LCA experts. Second, to produce operational guidelines for LCA practitioners to transfer ongoing and future LCA developments and bring comprehensiveness to the environmental assessment of upscaling.
