The telecommunications industry is undergoing a transformation towards sustainability, as evidenced by this year’s edition of MWC that drew over 100,000 participants from around the world. While 5G was a major theme, there was less emphasis on 6G than expected, and satellite communication and the Metaverse were prominent. Robots, AI, and wireless sensing were also highlighted as key features of the future of telecommunications. 
One of the most important takeaways from the conference was the role that green ICT can play in protecting the environment. During the keynote speech, top executives from major telco companies such as Telefonica and Orange emphasised the key role of the connectivity industry in shaping a more inclusive, resilient, and sustainable future. They acknowledged, however, that achieving sustainability requires consistent investments and the full engagement of all stakeholders in the telco value chain. 
The European Commission delegation, headed by the Commissioner Thierry Breton, also reiterated Europe’s strong commitment to leading the connectivity revolution in an environmentally friendly manner. They highlighted the opportunities available to all telco operators to contribute to building a sustainable future. As the industry continues to evolve, it is clear that sustainability and green ICT will remain crucial considerations for all stakeholders.
