Lowering the environmental impact of digital services and technologies is becoming a priority for both the operation of existing digital services and the design of future digital infrastructures. Energy consumption and carbon footprint are the two most talked about environmental impacts, and indeed, digital infrastructures today contribute 3 to 4% of the total greenhouse gas (GHG) emissions in the world, with a growth of 8% per year. In particular, the part of the networking infrastructure alone is responsible for 2 to 14% of digital impacts, according to various sources, mainly due to their electricity consumption. This session will discuss the current status, the challenges, the research and industrial solutions that the community could explore.
