Fashion Footprint is a Chrome Extension that addresses the information gap in fashion sustainability influenced by YouTube content. Our project provides real-time sustainability scores for clothing items featured in fashion-related YouTube videos. By scraping and analyzing data from sustainability rating platforms and combining existing scores, we offer transparent insights into brand practices and material compositions. Our results show that brands frequently mentioned in YouTube videos often have poor sustainability ratings. By highlighting these issues, our project empowers consumers to reflect on their purchasing habits and make more informed, eco-friendly decisions and aims to reduce overconsumption driven by influencers on YouTube.
