Apple today announced it has nearly doubled the number of suppliers that have committed to run their Apple-specific production on 100 percent renewable energy, bringing the total number to 44.
The list of newly committed suppliers includes, among others, Gorilla Glass maker Corning, Face ID module provider Finisar, A-series chipmaker TSMC, Apple Watch manufacturer Quanta Computer, AirPods assembler Luxshare, and iPhone assemblers Foxconn, Pegatron, and Wistron.
Apple now expects to add five gigawatts of renewable energy to its supply chain by 2020, exceeding its goal of four gigawatts in that timeframe.
Apple says that manufacturing makes up 74 percent of its carbon footprint. To address this, Apple and its suppliers have invested in or procured a mix of clean energy technology, including wind and solar. Apple has also further expanded its supplier education and support initiatives.
Apple also announced that it has allocated all of its $2.5 billion in green bonds, the largest amount of any U.S. corporation. Through this, the company says it has contributed to 40 environmental initiatives around the world, including projects Apple has created to cover its entire electricity load.
Apple's Green Bonds also support environmental research and innovation. Projects include solar rooftops in Japan, an aquifer to conserve water in Oregon, and the creation of a custom alloy made of 100 percent recycled aluminum that is now found in the latest MacBook Air and Mac mini.
A year ago, Apple announced that its global facilities, including retail stores, offices, and data centers, are now powered with 100 percent renewable energy.
