Road to Net Zero: GHG Emission Reduction Strategies

Globe’s Scope 1 emissions are primarily from fuel consumption from facility gensets, fleet vehicles, and refrigerant consumption from cooling systems.

Globe has implemented multiple enterprise-wide programs to decrease fuel consumption for its gensets, successfully saving over one million liters of fuel in 2025 and generating approximately ₱153 million in cost savings. These results were achieved despite the compounded impact of severe natural calamities that hit the Philippines in 2025.

Globe drove this significant decrease in fuel consumption through key initiatives such as Genset Rationalization and Power Modernization, which strategically transitions sites from diesel-reliant gensets to permanent commercial grid power. The company also optimized its site energy storage by replacing traditional lead-acid batteries with Lithium-ion and non-toxic sodium-nickel (SoNick) "Molten Salt" alternatives.

Genset Rationalization

To optimize resource allocation and minimize unnecessary fuel consumption, Globe has strategically discontinued genset fuel delivery to sites with historically minimal power outages. Analysis of historical data indicates that backup battery systems can reliably sustain these sites during outages of less than four hours, rendering genset deployment unnecessary in such instances.

Impact: This rationalization saved over one million liters of fuel in 2025 and generated approximately ₱153 million in cost savings.

Hybrid and Electric Vehicle (EV) Roll-Out 

Globe has started integrating clean mobility into its operations, scaling up its sourcing of electric and hybrid vehicles for its company fleet, car plans, and employee shuttles.  

Impact: By the end of 2025, Globe successfully deployed 245 hybrid and fully electric vehicles (representing 6.85% of its combined fleet and car plans). This puts the company on track for its target of 500 EVs by 2030 for its fleet, which is projected to save ₱100 million in fuel costs and avoid 5 million kg of CO₂e over the initial 5-year use of the vehicles. 

Site Solarization

Globe is transitioning some of its access and core sites to solar power systems, not only in response to operational challenges, such as fuel price increases and fluctuations and supply disruptions from extreme weather, but also to reduce GHG emissions. This move seeks to lower dependence on fossil-based fuel and the use of diesel generators. 

Impact: As of end-2025, 179 cell sites are powered entirely by on-site solar PV installations, while another 15 sites are powered by a hybrid of on-site solar and off-site renewable energy through the Retail Aggregation Program (RAP).

Globe’s Scope 2 emissions arise from the purchase of electricity to power cell sites, core network facilities, data centers, corporate offices, and mixed-use facilities.

Renewable Energy Scale-Up

Globe initiated its transition to renewable energy in 2019, leveraging Power Purchase Agreements (PPAs) under the Department of Energy’s Green Energy Option Program (GEOP) and Retail Competition and Open Access (RCOA) frameworks. These enable facilities to directly contract with Retail Electricity Suppliers (RES)—with GEOP for facilities with a monthly average peak demand of 100 kilowatts or greater, and RCOA for those with 500 kilowatts or greater. By engaging directly with RES, Globe is able to source renewable energy, such as from solar PV or geothermal power plants. This strategic approach not only reduces Globe’s GHG footprint but also stimulates further investment in clean energy infrastructure, contributing to the Philippines’ commitments under the Paris Agreement through its Nationally Determined Contribution. 

Starting in 2025, Globe accelerated its transition to clean energy by leveraging the Retail Aggregation Program (RAP), which allowed Globe to integrate distributed assets, such as cell sites and small facilities, into its renewable energy sourcing program. Globe plans to expand RE sourcing via RAP by transitioning at least 3,000 sites by 2028, which is estimated to avoid 5.5 million kg of CO₂e annually once completed.

Impact: A twelve-fold increase in the number of sites powered by renewables was seen in 2025, expanding from 29 sites in 2024 to 358 sites in 2025. Renewable energy accounted for 34% of Globe's total electricity consumption. 

Green Network Equipment and AI

Globe has started replacing traditional cooling systems and equipment in select sites with intelligent, energy-saving infrastructure. This includes deploying Free Cooling systems that leverage ambient air to reduce mechanical refrigeration, and utilizing Artificial Intelligence (AI) and Machine Learning (ML) to optimize power consumption dynamically.

Impact: Globe achieved 20,800 new deployments of energy-saving solutions in 2025. One of these solutions include usage of AI that calibrates energy used based on real-time demand, which resulted in up to a 6.5% reduction in energy consumption, leading to electricity savings exceeding 15,848 MWh.

Chiller Optimization

Globe uses an energy management device called External Digital Demand Response Technology, or EDD-RT, that leverages AI and Internet of Things (IoT) to regulate cooling of piping systems and minimize electricity consumption without compromising preset facility conditions.

Impact: Globe has observed approximately 20-30% annual energy savings in using this technology.

Energy Management System 

Globe established an enterprise-wide Energy Management System (EnMS) in 2021, achieving ISO 50001:2018 certification in 2022, a first for the Philippine telecommunications sector. This ISO framework provides a robust structure for identifying major energy-consuming sites, proactively implementing energy conservation and efficiency projects, and rigorously measuring their impact. This EnMS is incorporated into Globe’s updated Environmental Sustainability Policy and promotes energy efficiency, conservation, and the use of alternative energy sources, in accordance with Republic Act 11285 (the Energy Efficiency and Conservation Act).

Globe’s Scope 3 greenhouse gas (GHG) emissions, which encompass indirect emissions from its value chain, are predominantly attributed to four categories: Capital Goods (Category 2), Upstream Leased Assets (Category 8), Purchased Goods and Services (Category 1), and Fuel- and Energy-Related Activities (Category 3). Capital Goods account for the largest share, followed by Upstream Leased Assets, reflecting the emissions linked to leased infrastructure. Purchased Goods and Services contribute significantly, mainly from the procurement of power and communication structures, IT devices, and other materials. Fuel and Energy-Related Activities make up a significant portion, stemming from upstream emissions associated with fuel and electricity consumption.

Category 1 (Purchase Goods and Services) and Category 2 (Capital Goods)

Internal Carbon Pricing

Globe initiated an Internal Carbon Pricing (ICP) pilot program in 2024 to proactively address its carbon footprint and drive sustainable business practices. Progressing from its pilot phase, Globe actively applied a shadow price of USD 20 per tonne of CO2 in 2025. This successfully steered procurement capital away from internal combustion engine (ICE) vehicles toward hybrid electric fleets and higher-efficiency inverter cooling system. ICP assigns a monetary value to GHG emissions, promotes informed decision-making, and encourages emissions reduction. Globe anticipates that this will encourage energy efficiency, reinforce decision-making with sustainability considerations, and stimulate green innovation across business units.

Paperless Transactions

Globe leverages digital platforms like MemoApp and AppSheet to automate workflows and minimize resource consumption. In 2025, these tools collectively saved approximately 365 reams of paper, which is equivalent to 182,410 sheets of paper or 22 full-grown trees. AppSheet currently has 6,767 active apps running, empowering employees to create custom applications for customer-facing queuing and inventory management without the need for developer support.

Take Back Program for Employee Service Units

Globe’s iOwn Program empowers employees to take ownership of their assigned devices for free at the end of their use. Laptops that are not purchased are systematically assessed for a second life either as internal loaner devices or as donations to schools and NGOs. In 2025, over 79% of unpurchased laptops were designated for internal reuse, effectively narrowing the demand for new hardware. 

Category 3 (Fuel- and Energy-Related Activities) 

To reduce Globe’s indirect energy footprint, Globe’s is transitioning away from internal combustion engine vehicles toward hybrid electric vehicles (HEVs) and fully electric vehicles (EVs) to reduce fuel consumption. Simultaneously, Globe’s genset rationalization initiative transitions cell sites from diesel-reliant generator sets to permanent commercial grid power.

Category 7 (Employee Commuting)

Use of Electric Vehicle Shuttles for Employees 

In partnership with Global Electric Transportation (GET), Globe operates a fleet of three electric vehicles (EVs) dedicated to employee transport during peak hours from Monday to Thursday, with each trip accommodating up to 30 employees. 

Category 8 (Upstream Leased Assets)

Globe collaborates with tower companies, or TowerCos, to build greener cell sites, focusing on integrating more renewable energy. Furthermore, Globe has incorporated Artificial Intelligence and Machine Learning power-saving capabilities into cell sites sold to TowerCos, facilitating additional electricity savings and decarbonization.

Category 11 (Use of Sold Products) and Category 12 (End-of-Life Treatment of Sold Products)

Responsible Disposal, Donation, Reuse, or Resale 

Returned devices are assessed for responsible disposal, donation, reuse within Globe, or resale (post-refurbishment). This approach prioritizes maximizing the lifecycle of each device, reducing electronic waste, and supporting a circular economy for mobile technology. Defective mobile phones returned by customers undergo rigorous assessment for refurbishment and resale to prioritize life-extension. In 2025, 743 units were successfully refurbished and reintroduced to the market, avoiding an estimated 726 kg CO2e in lifecycle emissions, which is approximately equal to the emissions of five average Filipino households for a month.

Device Trade-In Program

The Globe Device Trade-In Program empowers Postpaid customers to responsibly retire their old devices while enjoying added value. Customers can begin the trade-in process online by answering questions about their device’s condition to receive an estimated trade-in value, which is applied as cashback on their postpaid bill. Devices are then collected by Globe’s partner for final assessment. Alternatively, customers can opt for an in-store evaluation at participating Globe locations. 

The Globe Trade-In Program allows Postpaid customers to give their old smartphones, tablets, or watches a second life in exchange for bill credits. This initiative successfully facilitated 613 device trade-ins in 2025, an 11% increase from the 552 devices traded in 2024. 

Gadget Exchange 

The Gadget XChange Program provides crucial support to Globe Postpaid customers, extending device lifespans by offering repair services for damaged devices. Furthermore, it offers replacements for lost or stolen devices and facilitates seamless device swaps for customers wishing to change colors or upgrade within a similar price range. The program helps reduce the environmental impact of discarded devices and promotes circularity. In 2025, the program saw a remarkable 357% increase in active subscribers, growing from 19,507 in 2024 to 89,186. 

eSIM and EcoSIM

Globe pioneered eSIM adoption in the Philippines in 2018, and adoption has grown exponentially since. In 2025, eSIM downloads surged by 133% to 597,559, preventing the production of approximately 2,390 kg of plastic. Globe also issued 365,276 Postpaid EcoSIM units and expanded the initiative to its Prepaid and TM markets by distributing 16,342,174 EcoSIMs in a half-card format to reduce plastic weight. Made from 100% recycled plastics, this enterprise-wide rollout avoided 34.15 tonnes of virgin plastic consumption in 2025

Paperless Billing

Since 2010, Globe has been advocating for paperless billing to limit the volume of paper consumption. By transitioning Globe Postpaid, Broadband, and Globe Business customers to email-based statements, the company has successfully saved over 122,707,344 sheets of paper in 2025. 

Recyclable and Upcyclable Packaging

In 2025, Globe released 58,100 recyclable and upcyclable GFiber Prepaid and GOMO Fiber broadband boxes. Engineered for an extended lifespan, made from responsibly sourced materials, and printed with non-toxic inks, these boxes eliminate plastic pouches and can be repurposed into durable laptop stands. Additionally, Globe deployed 260,000 kraft paper bags across its nationwide retail stores to replace coated glossy paper bags, saving approximately 22 full-grown trees.

Through Globe’s decarbonization strategy, the company achieved a 15.13% absolute year-on-year reduction for its gross Scope 1 and 2 GHG emissions in 2025. 

Scope 1 and 2 GHG Emissions in tCO2e (Gross, Absolute)

Globe’s Scope 1 emissions are primarily driven by the consumption of fuel for facility gensets and fleet vehicles, as well as fugitive refrigerant gases used for cooling systems. Globe’s Scope 2 emissions arise from the purchase of electricity to power cell sites, core network facilities, data centers, corporate offices, and mixed-use facilities.

Greenhouse gas emissions specifically measured by the organization, and included in the SBTi target, are CO₂ (Carbon Dioxide), CH₄ (Methane), and N₂O (Nitrous Oxide).
