Sustainability in telecommunications spans the value chain, from energy-efficient network operation and data-center design to device security and lifecycle replacement decisions. Explore how metrics like energy per bit help track progress, and review global signals on net-zero commitments, efficiency initiatives, and renewables procurement. We also examine where the biggest gaps remain in mobile energy use, cooling, and policy standards as data traffic grows with 5G.
Key Takeaways
- 45% reduction in operational energy intensity for data centers is targeted by some operators adopting best-practice guidelines (e.g., ASHRAE/IEA aligned targets) by 2030
- 161 countries and 21% of global GDP reported net-zero targets as of 2024
- 12% of mobile network energy consumption reduction potential remains untapped according to the ITU-T L.1470 energy efficiency recommendations assessment
- 54% of network infrastructure decision-makers reported having a sustainability strategy for their telecom networks
- 65% of telecommunications operators said they have begun implementing energy-efficiency initiatives
- The ETSI standard EN 303 645 requires reasonable security—impacting sustainability via reduced lifecycle device replacements
- 17% annual growth is forecast for global mobile data traffic between 2022 and 2028
- 5G will account for 60% of global mobile subscriptions by 2026
- Liquid cooling deployments were forecast to grow to 25% of enterprise data center deployments by 2028
- Telecommunications is listed among the sectors with the highest share of climate-aligned lending opportunities in 2024 by the OECD
- 30% of IT and telecom companies reported using renewable electricity procurement instruments such as PPAs in 2023
- 1.2 GW of renewable power capacity was added by telecom and data center operators globally in 2023 (cumulative renewable procurement)
- 18.4% of global electricity was generated from renewable sources in 2022
- 2.0 million data centers worldwide are estimated, reflecting the scale of embodied and operational impacts that sustainability programs target
- 0.9% of global electricity demand was from data centers in 2022 (International Energy Agency estimate)
Telecoms are cutting energy use, but faster action on efficiency, renewables, and longer equipment lifecycles is crucial.
