The cosmetic industry has a significant lack of data on sustainability practices. The global market for cosmetics is expected to grow from $288 billion in 2021 to $415 billion in 2028 as more people populate the globe (Cosmetics Market Size, Share, & COVID-19 Impact Analysis, 2022). This research paper analyzes sustainability within the cosmetic industry. Specifically, comparing the practices between The Body Shop and Bath & Body Works. To test the hypothesis that The Body Shop is more sustainable than Bath & Body Works, a case study analysis was conducted to measure the companies’ performance in the environmental, economic, and social sectors. Comparable metrics were selected, and a pairwise comparison was completed to weigh the different metrics. To analyze the results, the Analytic Hierarchy Process (AHP) was used to ensure consistency in metric weights, and a Mann-Whitney U test was used to analyze the sector's final weights. The results verified the hypothesis that The Body Shop was more sustainable than Bath & Body Works. In all, the results support the idea that the cosmetic industry needs stronger regulations and oversight of cosmetic companies’ sustainability impact. One of the most prevalent limitations of this study is the lack of transparency and information from cosmetic companies. Moving forward, it is recommended to use data from multiple years with key performance indicators (KPIs) to assess sustainability performance more accurately.
