Sustainability Score
52%
While MLB has made some efforts toward sustainability with their MLB Green program, the shop's practices show room for improvement. Limited transparency regarding supply chain and manufacturing processes is concerning. Some positive steps include using recycled materials in select products and implementing energy-efficient shipping practices, but labor conditions in manufacturing facilities need better documentation and verification. The organization could improve by establishing clearer sustainability goals and providing detailed reporting on environmental impact.
