The carbon footprint of computing systems spans their entire lifecycle, including manufacturing, operation, transportation, and recycling. Notably, the widespread use of billions of hand-held devices, such as smartphones and tablets, along with essential web services, plays a significant role in global warming. Currently, the combined carbon emissions from computing and networking devices contribute about 2% to global carbon emissions—a figure projected to double in the next decade. Given the escalating production and consumption of digital data globally, it’s crucial to deeply understand and address the emissions from personal devices, data centers, and networking infrastructure within the Information and Communication Technologies (ICT) sector.
