Debate: Sustainable Networks are More than Just Energy Efficient

Start date: Tue, May 24th 2022 3:00 PM CET

In many countries, telecoms networks account for 3 to 5% of total energy usage, and with expected growth in cellular coverage, density and capacity only drastic changes in energy efficiency will prevent digital infrastructure being a leading carbon emitter. While a business case for reducing energy costs has supported a focus on energy efficiency so far, this is very different from suggesting that the networks are sustainable or even carbon-neutral. Should the industry continue to focus its priorities on energy efficiency? If not, how does it find a balance (and financial justification) between energy efficiency and a broader sustainability?
