The mobile industry has achieved a 13% reduction in carbon emissions over the past five years, even as global data traffic more than doubled, according to a new report from the GSMA, the trade body representing mobile network operators worldwide. The finding underscores significant energy efficiency improvements across the sector.
Emission Reduction Amid Traffic Growth
The GSMA's annual 'Mobile Net Zero' report, released on July 15, 2026, reveals that total carbon emissions from mobile operators fell from 245 million tonnes of CO2 equivalent in 2021 to 213 million tonnes in 2025. During the same period, mobile data traffic surged by over 120%, driven by the proliferation of video streaming, social media, and IoT applications.
"This achievement demonstrates that decoupling emissions growth from traffic growth is possible," said John Giusti, Chief Regulatory Officer at the GSMA. "Operators have invested heavily in renewable energy, network modernization, and AI-driven energy management systems."
Key Drivers of Emission Cuts
The report attributes the emission reductions to three main factors. First, the adoption of renewable energy sources has accelerated, with operators sourcing 28% of their electricity from renewables in 2025, up from 18% in 2021. Second, network equipment upgrades, including the deployment of 5G and more efficient base stations, have reduced energy consumption per gigabyte of data by 35%. Third, AI-powered network optimization has allowed operators to dynamically adjust power usage based on demand, cutting waste during off-peak hours.
"Energy efficiency is not just an environmental imperative but a business one," added Giusti. "Lower energy costs improve profitability, especially as data traffic continues to grow exponentially."
Scope 1, 2, and 3 Emissions
The report breaks down emissions into three scopes. Scope 1 emissions (direct from owned sources) fell by 11%, Scope 2 emissions (from purchased electricity) dropped by 15%, and Scope 3 emissions (from supply chain) decreased by 8%. The GSMA notes that Scope 3 remains the most challenging area, as it includes emissions from device manufacturing and network construction.
"We are working with suppliers to set science-based targets, but progress is slower than we would like," said Giusti. "Collaboration across the value chain is essential."
Regional Variations
Emission reductions varied by region. Europe and North America led with reductions of 18% and 16% respectively, thanks to strong policy support and corporate renewable energy procurement. Asia-Pacific saw a 10% reduction, while Africa and the Middle East recorded a 7% decline, constrained by limited renewable energy infrastructure and rapid network expansion.
The GSMA report also highlights that operators in developing markets face unique challenges, including unreliable grid power and higher reliance on diesel generators. However, the report notes that off-grid solar and battery solutions are gaining traction in these regions.
Industry Targets and Future Outlook
The GSMA has set a target for the mobile industry to reach net-zero emissions by 2050, with an interim goal of a 50% reduction in absolute emissions by 2030 compared to 2020 levels. The report indicates the industry is on track to meet this target, provided current trends continue.
"The next five years will be critical," Giusti emphasized. "We need to accelerate the deployment of renewable energy, especially in emerging markets, and continue to innovate in energy-efficient technologies."
The report also calls for supportive government policies, including streamlined permitting for renewable energy projects and incentives for green network infrastructure. The GSMA estimates that achieving the 2030 target will require cumulative investments of $50 billion in energy efficiency and renewable energy across the industry.
Impact on Consumers and Digital Inclusion
The emission reductions have not come at the expense of service quality. Mobile data speeds have improved by 40% globally since 2021, and the number of mobile internet users has grown by 800 million to reach 5.2 billion. The GSMA argues that sustainable network expansion is essential for bridging the digital divide without exacerbating climate change.
"We can have both connectivity and climate action," Giusti concluded. "This report proves that it is possible."
