The concepts of the Metaverse and Web 3.0 have grown in popularity as "the successor to the mobile Internet". The Web 3.0 is a paradigm shift of the Internet towards user-centric decentralization. The primary principles of Web 3.0 will be especially realized in the Metaverse, which is the next stage in the development of the Internet. The Metaverse is expected to be a seamless and interoperable integration of Artificial Intelligence (AI) driven virtual worlds populated by user generated contents (UGCs), and accessible through virtual/augmented reality (VR/AR) technologies.

Currently, many of these enabling technologies are energy hungry. Firstly, the physical-virtual world synchronization for world building in the Metaverse requires high resolution streaming of 3D objects and real-time execution of the perception-actuation loop on the Internet of Things (IoT). B5G/6G or next-generation WiFi would be the edge tools, with the basic technologies, such as large-scale antennae, ultra-dense networking, new multiple access technology, full spectrum access, etc. Secondly, the training of and inference using AI models are computationally intensive. Thirdly, the energy consumption per transaction on major blockchains still outweighs that of traditional payment systems. These problems are exacerbated when computation operations are pushed to the network edge across edge devices that have heterogeneous and dynamic constraints. The around-the-clock maintenance of the Metaverse will require intensive computation load and heavy data traffic. Therefore, network densification would have to continuously increase, with the strict constraints of data rates and latency, as well as the extreme bandwidth requirements for Metaverse applications. Under these circumstances, green technologies will have to be explored to realize the sustainable development of the Metaverse. Consequently, the topics of interest include, but are not limited to, the following:

New Architectures for green technologies for the Metaverse in Future Networking and Communications
Physical layer Technologies, such as MIMO, ultra-dense networking, etc., helped by Artificial Intelligence for green technologies for the Metaverse
