Telefónica and Huawei are part of the EU-funded EXIGENCE consortium, which aims to address the environmental impact of digital devices as the world moves towards 6G technology. This initiative, involving ten organizations across seven EU nations, focuses on reducing the carbon footprint of telecommunications through energy consumption measurement, service optimization, and promoting sustainable user behavior. With the anticipated surge in energy consumption from connected devices, the project emphasizes the importance of integrating sustainability into digital transformation to meet the European Green Deal's climate neutrality goals by 2050.
