Advancing Social Life Cycle Assessment: A Novel Approach to Uncertainty Analysis
Beatriz Cassuriaga, Andreia Santos, Ana Carvalho
TL;DR
This paper introduces a new method to account for uncertainty in social life cycle assessments, improving the reliability of social risk evaluations in manufacturing.
Contribution
The paper proposes a novel uncertainty analysis methodology for social life cycle assessment characterization factors.
Findings
The cellulose-based material showed lower social impacts in ship counter bars compared to conventional materials.
The methodology is easily applicable and provides consistent results across different case studies.
Uncertainty modeling enhances the transparency and robustness of social performance evaluations.
Abstract
Social life cycle assessment is gaining importance, being recognized as a well-established methodology to evaluate potential social risks that might occur in value chains. Several studies have been conducted in applying traditional social databases (e.g., Social Hotspot Database) to assess social risks, but these studies generally do not consider the uncertainty associated with the characterization factors used in the models. This type of uncertainty is intrinsic to social risk modeling, as the underlying indicators and expert-based assessments are inherently variable. Therefore, this paper aims to address this literature gap by proposing an uncertainty analysis methodology that explicitly accounts for the uncertainty associated with the characterization factors. It represents one of the first studies to model such uncertainty directly within the context of the Social Life Cycle…
