Studio Display and Studio Display XDR were built with the environment in mind, and bring Apple even closer to reaching its ambitious plan to be carbon neutral across its entire footprint by 2030. Both are made with recycled content, including 100 percent recycled aluminum in the stand and 80 percent recycled glass in the standard glass option. Studio Display and Studio Display XDR are designed to be durable, repairable, and also offer industry-leading software support, while meeting Apple’s high standards for energy efficiency and safe chemistry. The paper packaging is 100 percent fiber-based and was designed to collapse so it can be easily recycled.4
