Save Our Planet
Telkom has developed a sustainability and emission reduction strategy based on six decarbonization levers. The initiatives begin with energy savings and equipment modernization, including improving lighting efficiency, enhancing the cooling management system, and upgrading technology to boost operational efficiency.
These efforts are strengthened through electrification, such as replacing diesel gensets with PLN electricity and transitioning ICE vehicles to electric vehicles. Telkom also expands clean energy use through solar PV installation, hydrogen fuel cell gensets, and lithium battery energy storage.
Market based instruments like REC and PPA are utilized to verify renewable energy use, while carbon offsets through carbon credit purchases and NBS initiatives address remaining emissions. These actions align with government efforts on PLN’s renewable energy transition, biodiesel mandates, and the low GWP refrigerant roadmap, forming a strong foundation for Telkom’s sustainable energy transition.
The six levers are translated into a Transition Pathway that outlines TelkomGroup’s journey to reducing Scope 1 and Scope 2 emissions and achieving Net Zero Emissions by 2060. This transition pathway is structured into three timeframes: the short term (2023-2030), the medium term (2030-2050), and the long term (up to 2060).
During the initial period of 2023-2030, Telkom targets up to a 20% reduction in emissions from the baseline through energy efficiency measures and network modernization, including the implementation of RAN AI, liquid cooling, and outdoorization. In this phase, Telkom also begins the development of solar PV installations, with a target capacity exceeding 14 MWp before 2030.
Entering the 2030-2040 period, emission reduction efforts are further strengthened, with a new target of achieving a 40% reduction by 2040. At this stage, Telkom initiates the electrification of its entire operational vehicle fleet, transitioning fully to electric vehicles (EVs). Solar PV capacity is expanded to more than 20 MWp, and over half of the electricity demand of data centers is planned to be sourced from renewable energy.
In the 2040-2050 period, Telkom deepens its commitment with a goal of achieving a 70% reduction in emissions. Solar PV capacity continues to increase to more than 30 MWp, while data centers powered by renewable electricity are expected to exceed 60%.
By 2060, Telkom aims to reach a state of net-zero emissions, meaning the remaining emissions will be minimal and fully offset. Consistent execution of this Transition Pathway underscores Telkom’s commitment to supporting sustainable development goals and achieving Net Zero Emissions by 2060.
Aligned with the Transition Pathway, the graphic above illustrates TelkomGroup’s Emission Pathway toward achieving Net Zero Emissions by 2060.
The rising red line represents the business-as-usual (BaU) scenario, while the shaded area below it shows the contribution of Telkom’s various decarbonization initiatives in reducing Greenhouse Gas (GHG) emissions. Starting from a baseline of around 2 million tCO?e in 2023, the initial reduction up to 2030 is driven by energy efficiency efforts, the replacement of high-GWP refrigerants, and the utilization of solar PV.
Entering the 2030–2050 period, emission reductions become more significant in line with the decarbonization of the national grid, where PLN’s cleaner energy mix plays a major role in lowering Telkom’s electricity-related emissions. At the same time, the electrification of operational fleets becomes mandatory, with a target for all vehicles to transition to EVs before 2040. The combination of renewable energy (RE), REC/PPA mechanisms, and building efficiency further strengthens the reduction in emissions.
Toward 2060, all these initiatives lead TelkomGroup to achieve a 100% reduction in emissions, with carbon offsets used only for residual emissions that cannot be technically eliminated. These residual emissions will continue to be managed even beyond 2060 to maintain net-zero status. The graphic underscores TelkomGroup’s commitment to a comprehensive decarbonization journey driven by technology, government policy, and sustainable operational transformation.
TelkomGroup acknowledges the increasing risk of climate change and its potential impact on all business lines, including service quality for customers. In response, Telkom initiated a climate risk assessment in 2023, incorporating the identification of climate risks and opportunities, as well as climate scenario analysis, to guide adaptation strategies. The methodologies, processes, results, limitations, and assumptions are detailed in the 2023 Climate Risk Report, in alignment with the IFRS S2 disclosure framework. Telkom has established a strategy to enhance business resilience to climate risks, including setting key metrics and targets, with GHG emissions as a main metric, which will be continuously monitored. Telkom’s target includes Scope 1 and 2 emissions reduction by 20% by 2030, compared to the 2023 base year, and achieve net zero for Scope 1 and 2 emissions by 2030.
TelkomGroup’s commitment to energy efficiency is reflected in its investment, covering the procurement and retrofitting of LED lights, energy-efficient refrigerants, batteries, and low-energy monitors. As part of its commitment to transitioning toward a net zero emission, Telkom Group has deployed renewable energy at BTS and public facilities. TelkomGroup has also expanded its use of electric vehicles (EVs) to support operational activities, complemented by providing EV charging station points. Currently, 17% of Telkom’s total operational vehicle fleet consists of EVs.
Telkom’s core operations rely on material resources, such as communication support equipment, to ensure the seamless delivery of services to customers. In the process, these activities produce waste that requires responsible management following sustainability principles.
One of the wastes generated by TelkomGroup's operational activities is fiber optic cable waste. Telkom targets a minimum of 70% of fiber optic cable waste to be diverted from final disposal by 2030. Until 2024, it is recorded that the amount of fiber optic cable waste diverted from final disposal by TIF is 176,046 kg or 80% of the total cable waste. This figure is calculated by comparing the amount of cable waste that can and has been reused to the cable waste collected by TIF.
Telkom promotes digitalization by implementing a policy on the use and distribution of information through online system, such as online official memo, virtual meetings, joint files, online surveys, and IT-based HR services. This aims to maximize the digitalization efforts and IT adoption to reduce use of paper.
TelkomGroup sources its water supply from the Regional Drinking Water Company (PDAM). Recognizing the potential environmental impacts associated with water use, TelkomGroup is committed to implementing responsible water management practices across its operational buildings. To support this initiative, TelkomGroup operates Sewage Treatment Plant (STP) facilities that process liquid waste through filtration stages. This ensures that wastewater discharged into urban sewer systems or recycled for reuse meets safety standards and does not contain grey or black water.
TelkomGroup recognizes the environmental impact of its business operations, including GHG emissions and waste, as outlined in the previous section. As part of its commitment to environmental responsibility, Telkom actively participates in biodiversity conservation, despite not having operational areas directly in the conservation zones. Our responsibility is further reflected in the absence of public complaints related to environmental issues arising from Telkom’s operations in 2024.
In 2024, Telkom facilitated the planting of 102,450 trees across a total area of 4.6 hectares, in partnership with local communities through Telkom’s Hutan Binaan Digital program. In addition to terrestrial ecosystem conservation, Telkom is actively engaged in marine ecosystem restoration initiatives. In 2024, Telkom planted 62,250 mangrove trees (Rhizophora mucronata) and transplanted 896 coral reef substrates (Acropora sp and Porites sp) across multiple coastal areas in Indonesia.
