Telecom’s Green Revolution: How Mobile Networks Are Cleaning Up the Digital Age
By Matthew Eloyi
For decades, the growth of telecommunications has been measured by the number of people connected, the speed of networks and the volume of data transmitted. But as the world confronts the realities of climate change, a new measure of success is emerging — how sustainably the digital world can expand.
A new report by the Global System for Mobile Communications Association (GSMA) has revealed that the mobile industry is making significant progress in reducing its environmental impact, cutting operational emissions by 13 per cent between 2019 and 2024 despite a 10 per cent rise in mobile connections globally.
The findings contained in the GSMA Mobile Net Zero 2026 State of the Industry on Climate Action Report indicate that the telecommunications sector is gradually rewriting the narrative that technological advancement must come at the expense of the environment.
The report, which examined energy and emissions data from more than 110 mobile operators covering 85 per cent of the world’s mobile connections, showed that operators achieved their fastest annual reduction in emissions in five years, recording a five per cent decline in operational emissions in 2024.
The development comes at a time when global demand for digital services continues to surge. Between 2019 and 2024, data traffic more than quadrupled, driven by increased smartphone usage, digital services, artificial intelligence applications, cloud computing and the expansion of online economies.
Yet, despite this unprecedented growth, telecom operators have succeeded in reducing emissions through improved energy efficiency, network upgrades and increased reliance on renewable power.
According to the GSMA, the industry’s transition towards cleaner energy has become the foundation of its climate strategy, with renewable electricity emerging as the single largest contributor to emissions reduction.
Mobile operators purchased or generated about 70 terawatt hours of renewable electricity in 2024, helping increase the share of renewable energy in their electricity mix from 10 per cent in 2019 to 24 per cent five years later.
The progress reflects a broader shift in the telecommunications sector, where companies are increasingly investing in solar power, battery storage, energy-efficient infrastructure and modernised networks to reduce dependence on fossil fuels.
However, the GSMA warned that the journey towards a low-carbon digital economy remains challenging, particularly as the industry works towards its target of reducing emissions by 45 per cent by 2030 and achieving net zero emissions by 2050.
The association stressed that government support would be critical in sustaining the momentum.
“We urge governments to expand renewable energy access to keep the mobile industry on course for net zero emissions by 2050,” the report stated.
It called for reforms that would modernise electricity markets, encourage renewable energy investments and simplify approval processes for clean energy infrastructure.
For John Giusti, GSMA Chief Regulatory Officer, the progress made by telecom operators demonstrates that economic growth and environmental responsibility can coexist.
“Operators are connecting more people, carrying more data and supporting digital economies around the world while still reducing emissions,” he said.
Giusti noted that access to affordable and reliable renewable energy would determine how quickly the industry could accelerate its decarbonisation efforts.
“Policymakers have a vital role in creating the conditions that enable investment in clean energy infrastructure and accelerate the transition to net zero,” he added.
Beyond climate benefits, the GSMA said renewable-powered networks could strengthen energy security, improve infrastructure resilience and support sustainable economic development, especially in emerging markets where energy reliability remains a challenge.
The report also highlighted growing commitments among telecom companies to climate action. As of June 2026, 81 mobile operators had adopted near-term science-based climate targets, representing nearly half of all global mobile connections.
Additionally, 50 operators had committed to net zero goals, while 46 had received validation from the Science-Based Targets initiative.
Despite these achievements, the GSMA identified supply chain emissions as the biggest obstacle to achieving deeper reductions. Known as scope three emissions, these account for about 75 per cent of the mobile industry’s total carbon footprint.
The association said operators would need stronger partnerships with suppliers and greater adoption of circular economy practices to address emissions generated from manufacturing, transportation and equipment disposal.
Another major area of concern is the energy consumption of telecommunications towers. The GSMA noted that the world’s 100 largest tower companies consumed more than two billion litres of diesel in 2024.
The association believes that replacing diesel-powered systems with solar energy, battery storage and smarter energy management solutions could significantly reduce emissions from tower operations.
Meanwhile, the rapid rise of artificial intelligence is creating new questions about the future energy demands of digital infrastructure. While AI has increased electricity consumption in data centres, the GSMA said its direct impact on mobile network energy use remains limited.
However, it urged continued monitoring as AI becomes more deeply integrated into communication networks and digital services.
The report also emphasised the growing importance of climate resilience, as telecom operators face increasing threats from floods, storms, heatwaves and other extreme weather events.
With communication networks becoming essential to modern life — from financial services and healthcare to education and emergency response — ensuring their sustainability has become a global priority.
The GSMA’s findings suggest that the future of telecommunications will not only be defined by faster connections and wider coverage but also by the industry’s ability to deliver a greener, more sustainable digital world.
As billions of people continue to depend on mobile technology, the race is now on to ensure that the digital revolution does not leave behind an environmental burden.
