The environmental impacts of various systems of production and consumption have been studied for several decades by developing and applying life cycle assessment (LCA) with its own ISO standard. However, the assessment of social sustainability, and its integration with economic and environmental sustainability, are still in the developmental stage. Life cycle sustainability assessment adds economic and social inventories and indicators to the environmental framework, or going further, integrates them. LCSA methodology is being increasingly applied and developed, as charted in a past special issue in this journal (https://onlinelibrary.wiley.com/toc/15309290/2017/21/6)
More recently, the 2030 Agenda for SDGs adopted by the United Nations Sustainable Development Summit aims to achieve a balance between people, planet and prosperity. LCSA methodology is currently gaining momentum beyond case studies toward its potential use as a policy tool to achieve UN SDGs. An example of a question answered by LCSA is “to what extent does a product system and/or the large-scale adoption of a product/service help in achieving (or not miss) SDG targets better than another one?” While various studies have explored this integration, the Journal of Industrial Ecology seeks new research for this special issue to promote the use of LCSA for the cohesive achievement of the SDG framework.
The goals of the special include:
- Promoting original research that applies or develops quantitative and/or qualitative LCSA-related methodologies to support decision-making related to multiple (at least 2) SDGs in different economic sectors/industries/systems, and at different temporal and geospatial scales, including the local versus global dimension. Authors need to identify research gaps in literature and articulate the intellectual contributions of the work.
- Encouraging the integration of LCA with other advanced modeling techniques to better incorporate social, environmental, and economic considerations for improved LCSA methodology in support of various SDGs.
- Exploring how LCSA can contribute to the achievement of the SDG framework as a whole. For example, submissions are encouraged to show how SDGs can be achieved by holistically assessing environmental, social, and economic impacts and by uncovering hidden relationships between goals and targets. LCSA has the potential to serve as a systematic framework to cultivate and foster cross-disciplinary research for scholars who may be interested in a particular dimension of the SDGs or a global governance scheme. Submissions demonstrating the broader leadership of LCSA in supporting inter/cross-disciplinary research are encouraged.
- Further developing the assessment and coverage of interlinkages, trade-offs and prioritization of SDGs in LCSA methodology. In light of this, the characterization of positive impacts, such as product benefit or handprint assessment, and how to aggregate them with negative impacts is also key. Moreover, the relationship with conventional areas of LCSA-methodology should be explored with (re)consideration of the ethical backbone, such as social justice or equity issues. A potential gap between the current research focus of LCSA and SDGs is scale—the product itself may have negligible direct contributions to SDGs but could have significant impacts at a large-scale production and/or consumption. Submissions focusing on specific products or technologies should take this into consideration.
- Considering further developments in the SDG community, such as a possible revision of the SDG framework (https://www.nature.com/articles/d41586-020-02002-3), and studying how these possible adaptations could be flexibly covered in LCSA methodology. Submissions are encouraged to discuss policy and governance implications beyond achieving and revisiting SDGs based on LCA evidence. For example, how can science-based evidence obtained from LCSA and SDGs research support decision-making in policy and determining social priorities?
Case studies that focus on the application of LCSA methods need to demonstrate and highlight the innovations with respect to methodology, new knowledge, or new data.
Submissions are welcome on the development and/or application of LCSA-based indicators that are relevant for policy and planning purposes by a variety of stakeholders within the framework of the SDGs.
