Lower energy consumption was already an important design criterion in the course of 5G research and development. But with climate change progressing, this requirement is becoming even more important for the design of 6G. Thus, another question to address is the environmental sustainability of 6G. We discuss this topic in two different chapters, showing two complementary viewpoints. In Chapter 4, authors look at technical solutions to provide more sustainable cellular networks, relying on an intensive use of AI mechanisms. First, they identify the main factors of energy consumption in mobile networks. They then provide a holistic approach for defining a more sustainable 6G based on AI training executed at the edge of the network. Authors of Chapter 5 argue that reducing network energy consumption per byte transferred is not a sufficient path when the bandwidth consumption is continuously increasing (rebound effect). The question of sustainability is therefore not only a technical question but also a social and societal issue. Here, marketing will be an important point, along with consumers’ rising awareness of the impact of information technologies on global warming. Beside the eco‐design of networks and services, the question of changing the way we consume network and service offers should be addressed, with a possible trend toward more digital sobriety.
