Digital sustainability refers to the practice of designing, developing, deploying, and maintaining digital technologies, software systems, and data infrastructures in an environmentally, economically, and socially responsible manner. It involves minimizing the carbon footprint and energy consumption of data centers, extending hardware device life cycles through efficient software design, reducing electronic waste, and leveraging advanced digital innovations to solve broader ecological and climate challenges. The overarching goal is to ensure that digital transformation accelerates green transitions rather than compounding global resource depletion.
