In this article, scientists look at how creating customized products on a large scale can impact the environment. They focused on the carbon footprint of personalized items to see if they are sustainable. By using a method called Life Cycle Assessment, they studied two examples involving personalized products and eco-friendly car choices. The research suggests that while making personalized items can better meet customer needs, it might also lead to more environmental harm due to increased variability and production efforts. The study indicates that considering environmental impacts in the design of personalized products can help improve sustainability in manufacturing processes.
