Introduction

Social Life Cycle Assessment (SLCA) is a methodology used to evaluate the social impacts associated with the life cycle of a product or service. This field has been evolving, with researchers and practitioners continuously refining its methodologies and applications. The following synthesis presents the latest trends and developments in SLCA research.

Key Insights

Methodological Refinement and Critical Analysis:
- SLCA methodologies are undergoing in-depth and critical analysis to define the epistemological and methodological aspects, moving beyond the initial UNEP/SETAC Guidelines .
- There is a need for a scientifically accepted SLCA method, with current methods being inherently different and lacking standardization.
Development of New SLCA Methods:
- New SLCA methods, such as performance reference point and impact pathways methods, are being proposed to address the gaps in existing guidelines.
- Combining different methods, like performance reference points and impact pathways, is suggested as a future research direction to enhance SLCA methodologies.
Application and Case Studies:
- Case studies play a crucial role in understanding the application of SLCA and identifying its strengths and weaknesses .
- The results from case studies can significantly influence decision-makers and help in refining SLCA methodologies.
Focus on Social Hotspots:
- Refining the social hotspots database and the social hotspot index calculation method is identified as a key area for future research.
Flexibility and Applicability:
- SLCA is recognized for its flexibility and ability to quantify social impacts, making it a powerful tool in sustainability science.
- The method can effectively measure social impacts and provide a sound basis for decision-making.

Conclusion

Recent research in Social Life Cycle Assessment (SLCA) highlights the ongoing refinement of methodologies and the critical analysis of existing guidelines. New methods are being developed to address current gaps, with a focus on combining different approaches for better standardization. Case studies continue to be essential in understanding and improving SLCA applications, while the refinement of social hotspots databases remains a key area for future research. Overall, SLCA is evolving as a flexible and powerful tool for assessing social impacts in sustainability science.
