GSMA: Mobile networks cut operational emissions as data traffic quadruples
The GSMA says mobile operators reduced operational emissions by 13% while connections rose 10% and mobile data traffic more than quadrupled, but access to renewable energy remains critical.
Mobile networks are carrying dramatically more data without a matching rise in operational emissions, according to the GSMA’s latest climate assessment. In its announcement about the Mobile Net Zero 2026 report, the industry body says operators reduced operational emissions by 13% between 2019 and 2024. During the same period, the number of mobile connections increased by 10%, while mobile data traffic more than quadrupled.
The result is an important signal for an industry that is expanding both its network footprint and its computing workload. Smartphones, video services, cloud applications and connected devices are all placing heavier demands on mobile infrastructure. The GSMA’s findings suggest that efficiency measures are already offsetting part of that growth, but they also make clear that the transition is not complete.
Efficiency gains are keeping emissions under pressure
The report covers operational emissions from mobile operators, rather than the full carbon footprint of every device, network supplier or customer activity. The GSMA estimates that operators’ operational emissions stood at about 115 million tonnes of carbon dioxide equivalent in 2024, representing roughly 0.2% of global greenhouse-gas emissions.
That figure is not a reason to dismiss the sector’s environmental impact. Mobile networks operate continuously, and their electricity demand is tied to coverage, capacity, radio equipment, cooling, transport and data-centre infrastructure. As traffic grows, operators must increase capacity while keeping energy use under control. The reduction since 2019 therefore reflects a combination of more efficient equipment, improved network management and a gradual shift toward lower-carbon electricity.
The full GSMA Mobile Net Zero 2026 report also tracks how operators are setting formal climate targets. It says 81 operators have near-term science-based targets, with 77 validated by the Science Based Targets initiative. Fifty operators have committed to net-zero targets, including 46 with validated targets.
Renewable electricity is the next major constraint
The GSMA’s central warning is that efficiency alone will not deliver the industry’s long-term climate goals. Operators need greater access to affordable, reliable renewable energy, particularly in emerging markets where grid availability, energy pricing and infrastructure can vary substantially.
This matters because a mobile network can become more efficient without becoming low-carbon if the electricity powering it still comes largely from fossil fuels. The report therefore treats renewable access as both a climate issue and an operational one. Stable clean electricity can reduce emissions, improve energy security and make it easier for operators to plan network investment over the long term.
For network users, this is less visible than a new phone feature or a faster modem. The benefit appears indirectly through networks that can expand capacity without increasing energy demand at the same rate. In areas exposed to power interruptions, cleaner and more resilient energy systems can also support more dependable service. Those effects will depend on local infrastructure and operator execution rather than on a single global technology rollout.
AI could reduce network waste, but it can also increase demand
The report identifies artificial intelligence as a potential tool for improving network efficiency. AI-assisted systems can help operators forecast traffic, balance loads, place equipment into lower-power states when demand falls and adjust network resources dynamically. These techniques could reduce energy use while preserving service quality.
There is a counterweight. If operators build substantially more capacity in anticipation of future AI-driven traffic, the infrastructure required to support that growth could increase energy consumption before efficiency gains arrive. The GSMA therefore presents AI as neither an automatic solution nor an automatic problem. Its effect will depend on how accurately operators match capacity to real demand and how carefully they manage the energy cost of new computing workloads.
That distinction is especially relevant as AI features move closer to the mobile edge. Smartphones, smart glasses and other connected devices increasingly rely on rapid exchanges between local hardware, radio networks and cloud services. Better network intelligence may help those services respond more consistently, but the underlying infrastructure still needs electricity, cooling and maintenance.
Why the announcement matters now
The GSMA’s announcement does not announce a new consumer tariff, handset requirement or universal network upgrade. It is an industry assessment, backed by data and recommendations for operators, suppliers and policymakers. Its practical message is that mobile growth and climate progress can coexist, but only if efficiency improvements are paired with faster access to renewable electricity.
For operators, that means continuing to reduce energy use per unit of traffic while improving emissions reporting and working with suppliers on the wider equipment footprint. For governments and regulators, it means making clean power easier to procure and expanding the infrastructure needed to support reliable renewable generation. For suppliers, it increases pressure to deliver radios, core systems and data-centre equipment that consume less power without compromising coverage or performance.
Mobile connectivity is now essential infrastructure, so reducing its environmental cost is not separate from improving the user experience. The GSMA’s figures show that progress is possible even as usage accelerates. They also show why the next phase will require decisions about energy supply, network design and AI capacity—not just faster phones.
