Nike’s Considered line refers to the process it has undergone to consider its mammoth carbon footprint, and minimize it on all levels. Their line of Considered products has a special emphasis on using sustainable materials, but they’ve also implemented eco-conscious change across the board. In Nike Air products, they’ve switched from the greenhouse gas sulfur hexafluoride to climate-neutral nitrogen, eliminating 80% of the metric tonnage of their greenhouse gas emissions. They’ve made a 95% reduction in VOC usage across the business, and best of all, collect old sneakers (Nike and other brands) and recycle them into a material called Nike Grind, which they donate as a sports surface used to make tennis courts, playground surfaces, running tracks, and more. Considering that it takes 75,000 pairs to make a running track, that’s a lot of sneakers not ending up in landfills.
