• Keynote 1: 14:30 - 15:06 Speaker Chiara Lombardo (CNIT)
  Title: 6Green - Green Technologies for 5/6G Service-Based Architectures
  Abstract: The SDN and NFV paradigms have paved the way to a revolutionary wave in ICT technologies, which have heavily relied on virtualization more and more in the last decade and counting. Not only they have enabled new classes of applications and network services, and consequently shaped 5G, but for a long time it has also been implied that their adoption would result in a reduction of the power consumption/carbon footprint ascribable to the networks. However, updated forecasts have pointed out a noticeable usage and deployment increase of computing resources, increasing the associated infrastructure OpEx and CapEx, and, consequently, their carbon footprint and energy requirements in the last several years.
  In order to act upon the upcoming 6G technologies in a timely manner, several EU projects have been funded to address the sustainability issues of radio mobile networks and edge computing technologies. In particular, this keynote presents the 6Green Project, which aims to conceive, design, and realize an innovative service-based and holistic ecosystem able to promote energy efficiency across the whole 5/6G value-chain. 6Green aims to exploit and extend state-of-the-art cloud-native technologies and the B5G Service-Based Architecture to enable all the 5/6G stakeholders (from the ones acting at the infrastructure and network platform to vertical industries) reducing their carbon footprint by becoming integral parts of a win-win green-economy business, so that 5/6G networks and vertical applications would be able to reduce their carbon footprint by a factor of 10 or more.

14:30 –  16:00 Session S5: Sustainability

Chair: Timothy O’Farrell (University of Sheffield)

• Keynote 2: 14:30 - 15:06: Speaker: Esteban Selva (Orange),
  Title: Towards a 6G embedding sustainability
  Abstract: From its conception, 6G is being designed with a particular focus on sustainability. The general philosophy of the H2020 Hexa-X project work on sustainability in 6G is based on two principles: to reduce direct negative life cycle impacts of 6G systems as much as possible (Sustainable 6G) and to analyze use cases that maximize positive environmental, social, and economic effects in other sectors of society (6G for Sustainability or its enablement effect). To apply this philosophy, Hexa-X is designing 6G with three sustainability objectives in mind: to enable the reduction of emissions in 6G-powered sectors of society, to reduce the total cost of ownership and to improve energy efficiency. This keynote describes these objectives, their associated KPIs and quantitative targets, and the levers to reach them. An opening towards new holistic considerations on environmental sustainability to be brought forward in Hexa-X's sequel project, Hexa-X-II, is introduced.
  Speaker Bio: Esteban Selva is a research engineer in Sustainable Telecommunications at Orange, in the Orange Innovation Networks department. His research interests include modelling carbon emissions of telecommunication networks and bringing sustainability into the development of new telecommunication standards.
