Purpose
The aim of this study is to develop and test the applicability of a new subcategory assessment method (SAM) for social life cycle assessment using a case study on high-density polyethylene (HDPE) production by Dow Chemical Canada facility in Alberta, Canada.Methods
The methodology is characterized by six steps: (1) definition of the goal and scope of the assessment; (2) life cycle inventory data collection including context data at country level and company-specific data for foreground processes; (3) impact assessment where the subcategories’ results for foreground processes at company level are evaluated using a new SAM developed and the country social performance in the different subcategories is evaluated using some assessment intervals; (4) comparing the social performance of foreground processes to the social background context in sector or country; (5) evaluating the social performance of background processes using sector performance evaluation from Product Social Impact Life Cycle Assessment (PSILCA) database or country performance evaluation conducted in the study; (6) and discussion and conclusion.Results and discussion
The method developed was able to identify the subcategories that need high level or some level of improvements along the cradle-to-gate life cycle of HDPE. In addition, the stakeholders with high negative effect were highlighted in every life cycle stage. Through this approach, Dow Chemical Canada is able to prioritize its actions and focus on the areas where its performance is still low compared to its peers in the sector or compared to the situation in the country. Moreover, through using PSILCA database or country performance evaluation to investigate the social performance of background processes, Dow Chemical Canada can determine the social hotspots areas that need more focus from its suppliers.Conclusions
Applying the new subcategory assessment approach proposed in this study provides an objective way to assess the subcategories while differentiating between two levels of assessment: (1) the commitment to the social subcategory in the company’s policy (defined as cutoff requirement) and (2) the evidence of good/bad practices of the subcategory. In addition, the comparison of performance of the companies in foreground processes to the social background in sector or country has improved the objectivity further.4.

Life cycle sustainability assessment (LCSA) can be used as a tool to understand how products and operating systems can meet the United Nations’ Sustainable Development Goals (SDGs). However, existing linkages between SDGs and LCSA are limited and an analysis of coverage in literature is needed. In this paper, we propose a generic methodological framework establishing connections between LCSA categories at micro-level and SDGs at macro-level based on derivation from the literature. The qualitative heuristic research method developed builds on keyword literature search, bibliometric analysis, mapping, and narrative literature review for connection rationales. By using qualitative assessment levels, an assessment of linkages between LCSA categories and SDGs reveal that “technology development,” “public commitment to sustainability issues,” “access to material resources,” and “education provided in the local community” have the highest number of reported relationships with SDGs. Twenty-two LCSA categories were found with no direct/indirect connection with any SDG; reasons include absence of life cycle thinking perspective in SDGs and lack of sustainability-based discussion for workers, consumers, and value chain actors' stakeholder groups. Despite these gaps, the results provide new insights for industries looking to measure the contribution of their product systems along their life cycle in the context of SDGs supporting them to some extent, to select LCSA categories with either highest number of identified relationships to SDGs or that contribute to prioritized list of SDGs. The approach provides a starting point to improve transparency and consistency of reporting of sustainability performance of product systems by connecting LCSA to the global agenda for sustainable development. 相似文献
