Over the past two decades, the world has witnessed a dramatic rise in computing across data centers, mobile, and communication technologies. As of 2015 information computing technology (ICT) accounts for up to 5% of the global energy demand. Unfortunately, as the demand for computing grows with new applications and platforms so will its energy demand. Many technology companies, including Microsoft, Google, Facebook, Apple, and Amazon, have pledged to reduce their carbon footprints over the next decade. Meeting these pledges and enabling sustainable computing requires immediate action from the systems and architecture community.

Jay Chen is a Senior Researcher at ICSI who spent over 15 years designing and deploying ICTs in a variety of development contexts, from urban slums to rural areas — working with individuals, development organizations, and other stakeholders. He is a co-organizer of the LIMITS workshop, which concerns the role of computing in the face of real-world limits that are seldom discussed in contemporary computing research.
Profile photo of John MirandaJohn Miranda is a Director in Intel’s Data Center Group’s Strategy Office who has been advancing sustainability initiatives across Intel and its ecosystem partners.  This advocacy is motivated by the view that sustainability will be an imperative for the technology ecosystem to address over the coming decade.  John’s prior background includes running software engineering teams at Intel.  John is a guest lecturer at University of Arizona Eller Business School, and a board advisor to TTI Vanguard Advanced Technology Research Group.
Jordan TseJordan Tse is a Sustainability Program Manager at Facebook.  She leads the environmental work under the Responsible Supply Chain program, which supports the electronics supply chain for both Infrastructure and FB Reality Labs (e.g. Oculus & Portal).  
Photo of Josiah HesterJosiah Hester is the Breed Chair of Design and Assistant Professor of Computer Engineering at Northwestern University. He designs, builds and deploys tiny computers that last for decades, supporting applications in healthcare, conservation, and interactivity. He works towards a sustainable future for computing informed by his Native Hawaiian (Kanaka maoli) heritage. He applies his work to health wearables, interactive devices, and large-scale sensing for sustainability and conservation, supported by multiple grants from the NSF, NIH, DARPA, and 3M. He won the 3M Non-tenured Faculty Award in 2021. His work has received a Best Paper Award and Best Paper Nomination from ACM SenSys, and has been covered by the Wall Street Journal, The Verge, CNET, the BBC, and others.
