Social sustainability is often overlooked in the fast fashion industry because it's hard to measure. This study looked at how social sustainability in fast fashion companies can be turned into measurable goals. By analyzing sustainability reports from major companies like H&M and Inditex, the researchers found that measuring social sustainability varies between companies. Some challenges include sharing data, data availability, and the qualitative nature of the information. However, there are already ways to improve how social sustainability is measured in fast fashion companies.
