In 2021, Nike announced they were working with Newlight Technologies to find more eco-friendly materials for their sneakers. They specifically mentioned Newlight’s AirCarbon product which is a bioplastic that can be used to make shoes. The bioplastic is used as a replacement to leather, plastic, and other materials that are like that. ^[1]Newlight was reported saying that the goal is to reduce Nike’s carbon footprint. ^[2]They also are planning to make a 30% cut in their supply chain by the year 2030. Back in 2016 Nike started to use water free dyeing materials so that they can help reduce their water use in their Southeast Asian factories. ^[3] Nike France made their Reuse-A-Shoe program available online so that they could make it easier for consumers to send in their old shoes.   ^[4] They contributed 3,002,529 metric tons of Carbon Dioxide in 2017 combined from different sectors in the company like retail, manufacturing, management, and more. In 2017, it was estimated that 28,000,000 shoes were collected since its start in 1993.  Nike limited the mail-in option of the program because they are aware that the emissions from shipping would offset the good, they are trying to do.  They work with the National Recycling Coalition to help limit transportation of recycled shoes.  During transportation most of the vehicles that are used are using diesel or fuel oil. ^[5] Diesel oil emits 22.44 pounds of Carbon Dioxide per gallon. ^[6]
