TelkomGroup takes an active role in realizing a greener ecosystem through the implementation of sustainable business practices and responsible operational impact management. Focusing on climate, energy, and waste risk management is the cornerstone of maintaining business sustainability during changing environmental dynamics. Other aspects of environmental management, such as water management and biodiversity, are always managed in accordance with applicable regulations and standards.
Telkom has developed a sustainability and emissions reduction strategy based on six decarbonization levers: energy efficiency and equipment modernization, electrification and the transition to electric vehicles (EVs), renewable energy and energy storage, market-based instruments such as REC/PPA, carbon credits and Nature-Based Solutions (NBS), as well as support for government initiatives to reduce energy consumption and emissions.
Energy efficiency and equipment modernization focus on improving lighting efficiency, optimizing cooling management, and upgrading infrastructure. Electrification efforts aim to reduce reliance on fossil fuels by replacing diesel generators with electricity from PLN and transitioning operational vehicles to electric vehicles (EVs).
To promote renewable energy, Telkom is developing solar photovoltaic (Solar PV) installations, adopting hydrogen fuel cells, and utilizing lithium batteries as backup power systems. To manage indirect emissions (Scope 2), Telkom uses REC/PPA as instruments to support the verified use of renewable energy. Remaining emissions that cannot be eliminated are addressed through Carbon Offset initiatives, including the purchase of carbon units and investments in Nature-Based Solutions. These strategies are also aligned with government efforts to support the energy transition, increase the biodiesel mix, and adopt low-GWP refrigerants in accordance with the I-NCAP sustainable cooling roadmap.
As part of the implementation of this strategy, Telkom uses Renewable Energy Certificates (RECs) as one of the instruments to support the use of renewable energy and achieve its energy transition targets. The use of RECs is supported by a retirement certificate recorded in the TIGR Registry, with a total of 25,864 RECs retired on behalf of PT Telkom Indonesia (Persero) Tbk to support the Company’s renewable energy goals.

The six levers are translated into a Transition Pathway that outlines TelkomGroup’s journey to reduce Scope 1 and Scope 2 emissions and achieve Net Zero Emissions by 2060. This transition pathway is structured into three time periods: short term (2023–2030), medium term (2040–2050), and long term (up to 2060).
During the initial period of 2023–2030, Telkom targets a 20% reduction in emissions from the baseline through energy efficiency and network modernization, including the implementation of AI-powered RAN, liquid cooling, and outdoorization. During this phase, Telkom will also begin developing solar PV with a target capacity of more than 14 MWp by 2030.
Entering the 2030–2040 period, emission reduction efforts will be further intensified, with the target increasing to a 40% reduction in emissions by 2040. At this stage, Telkom will begin electrifying its entire operational vehicle fleet by transitioning to EVs. Solar PV capacity will also be expanded to more than 20 MWp, while more than half of the electricity demand of data centers is planned to be supplied by renewable energy.
Subsequently, during the 2040–2050 period, Telkom will further strengthen its commitment by targeting a 70% reduction in emissions. Solar PV capacity will continue to increase to more than 30 MWp, while the share of data center electricity sourced from renewable energy is targeted to exceed 60%.
By 2060, Telkom targets net-zero emissions, meaning that residual emissions will be minimized and fully balanced through offsets. Consistent implementation of this Transition Pathway demonstrates Telkom’s commitment to supporting the vision of sustainable development and achieving Net Zero Emissions by 2060.
In line with the Transition Pathway, the figure above illustrates the TelkomGroup Emission Pathway toward Net Zero Emissions by 2060.
The upward red line represents the business-as-usual scenario, while the area below it illustrates the contribution of various Telkom decarbonization initiatives to reducing Greenhouse Gas (GHG) emissions. Starting from a baseline of approximately 2 million tCO?e in 2023, the initial emission reductions through 2030 are driven by energy efficiency, the replacement of high-GWP refrigerants, and the utilization of solar PV.
TelkomGroup recognizes that the telecommunications industry is increasingly exposed to climate change challenges, particularly due to its heavy reliance on energy-intensive infrastructure such as telecom networks, base transceiver stations (BTS), and data centers. Climate-related risks—including flooding, extreme rainfall, and rising temperatures—are considered to have the potential to affect operational resilience and service continuity. Therefore, TelkomGroup has integrated climate change management into its corporate sustainability governance through the Sustainability Committee and the Climate Change and Energy Management Working Group. Climate management is carried out using an identify, assess, respond, and monitor framework to systematically identify climate-related risks and opportunities, evaluate their impacts on the business, develop mitigation and adaptation strategies, and monitor progress against targets on a regular basis.
As part of its low-carbon transition strategy, TelkomGroup launched its Climate Transition Plan in 2025 as a strategic roadmap toward low-carbon operations and the achievement of net zero emissions by 2060. Telkom has set a target to reduce Scope 1 and Scope 2 greenhouse gas (GHG) emissions by 20% by 2030, compared to the 2023 baseline. In 2025, TelkomGroup’s total GHG emissions reached 4,153,661.3 tCO2e (market-based), comprising 1% Scope 1, 52% Scope 2, and 47% Scope 3 emissions. A 45% reduction in Scope 1 emissions was achieved through the use of biodiesel blends (B40, B30, B20, and B10), while Scope 2 emissions increased by 6% due to asset expansion and the growing operational scope of data centers.
TelkomGroup’s commitment to energy efficiency is reflected in various modernization and energy-saving initiatives. One of the key programs is the implementation of the Integrated Smart Device for Advancing Energy Efficiency (iSave), an Internet of Things (IoT)-based system that enables real-time monitoring and control of building electricity consumption. In addition, Telkom has been implementing the Gerakan Peduli Efisiensi Energi (GePEE) program since 2023 to encourage collective energy-saving efforts across the organization. Other efficiency measures include the modernization of energy-efficient equipment, the adoption of more efficient cooling systems, the implementation of hybrid technology in BTS operations, and the development of greener data centers.
To support the transition to clean energy, TelkomGroup is also expanding the use of renewable energy through the installation of solar photovoltaic (PV) systems at operational facilities and data centers, with a target capacity of more than 14 MWp by 2030. Furthermore, the company aims for more than 50% of its data centers to be powered by renewable energy by 2040 and for 100% of its operational vehicle fleet to transition to electric vehicles by the same year. Telkom is also implementing independent and hybrid energy solutions at BTS sites to reduce reliance on the power grid, particularly in areas vulnerable to extreme weather disruptions.
As a telecommunications service provider, TelkomGroup’s operations rely heavily on network infrastructure and data centers, which require the use of various resources. These activities inevitably generate waste that must be managed responsibly to minimize operational impacts while creating long-term sustainability value for the business, stakeholders, and the environment.
In 2025, the total waste generated by TelkomGroup reached 41,157.5 tons, consisting of both hazardous and non-hazardous waste. One of the key priorities in waste management is electronic waste, including fiber optic cable waste. As of 2025, TIF successfully diverted 166.9 tons of fiber optic cable waste from final disposal, equivalent to approximately 73% of the total cable waste managed.
Telkom also continues to promote digitalization through the implementation of digital memos, virtual meetings, document-sharing systems, online surveys, and IT-based HR services to reduce paper consumption. In addition, TelkomGroup implements electronic waste management programs through initiatives such as Eduvice, the use of environmentally friendly packaging, and the provision of Reverse Vending Machines (RVMs) to support the sustainable application of a circular economy.
TelkomGroup proactively manages water resources by mapping scarcity risks using the WRI’s AQUEDUCT Tool, identifying 12.9% of its operational areas are in the category of extremely high-water stress, while the other 29.9% are in the category of high-water stress. With a total third-party water withdrawal of 3,728 ML in 2025, the company ensures environmental sustainability by operating Sewage Treatment Plant (STP) facilities at major buildings, adhering to Ministry of Environment and Forestry (KemenLHK) standards. Furthermore, the Telkom Hub office complex has adopted circularity principles through wastewater recycling management. Specifically at the TLT Building, treated wastewater from the STP and condensation from Air Handling Units (AHU) are repurposed for cooling systems and landscape irrigation.
Beyond operations, Telkom contributes to SDG 6 by expanding access to clean water and proper sanitation in infrastructure-limited areas. Collaborating with local governments and partners, Telkom builds boreholes, water treatment plants, and sanitation facilities (MCK), while providing hygiene education. In 2025, this initiative was successfully implemented across 99 locations in 17 provinces, benefiting over 58,501 individuals.
Additionally, TelkomGroup is committed to biodiversity preservation through pentahelix collaborations focused on ecosystem restoration and community empowerment. By 2025, the company has planted 80,800 trees across 8.1 hectares in various "Hutan Binaan Digital," achieving a 70% survival rate. To ensure transparent monitoring, Telkom utilizes WebGIS (Telkom Green Digital) technology to provide public access to spatial visualizations of conservation areas.
In marine ecosystems, Telkom has planted 110,042 mangroves and seagrasses, and transplanted 780 coral reef substrates. This initiative also involves comprehensive carbon stock measurements in collaboration with Telkom University, following the SNI 7725:2019 standard.
