Our environment
NetLink strives to reduce our environmental footprint, improve resource efficiency, and ensure our operations remain resilient to climate change risks.
NetLink aims to reduce our Scope 1 and 2 emissions by 50% by FY30 (using FY22 as a baseline) and achieve net zero by 2050.
NetLink recognises the severity of climate change impacts on humanity, and we are committed to reducing our environmental impact by focusing on energy efficiency and sustainable practices throughout our operations and supply chain.
Our new Seletar Central Office (CO), which achieved operational readiness in April 2025, was awarded Platinum certification under the Green Mark for Data Centres Scheme (2024). Our other existing COs have transitioned to LED lighting and implemented detection systems to enhance our monitoring of refrigerant leaks, a source of Scope 1 emissions.
We continue our efforts towards sustainable asset renewal, including upgrading the chiller systems of our existing COs to more energy-efficient models, as well as progressive electrification of our company vehicle fleet.
We have also adopted the Task Force on Climate-related Financial Disclosures (TCFD) recommendations to guide our reporting and assessment of climate change risk. With the enhanced sustainability reporting regime introduced by SGX RegCo, from FY25 we have started to progressively incorporate the climate-related disclosure requirements of the IFRS Sustainability Disclosure Standards (IFRS SDS) published by the International Sustainability Standards Board (ISSB) in our sustainability reporting. As we improve the quality of our climate disclosures, we seek to provide our key stakeholders with a better understanding of the business and financial impacts of climate change on our operations and the steps we have taken to mitigate climate-related risks and opportunities identified.
Target: Reduce Scope 1 and 2 emissions by 50% by FY30 (using FY22 as a baseline) and achieve net zero by 2050.

Given the limited availability of resources in Singapore, we are committed to optimising and conserving our resources without compromising efficiency. Our primary focus areas in resource management include effective waste and water management.
Waste management
Our major sources of waste are fibre scraps (excess cable from fibre cable installation that are too short to be reused) and recovered used fibre cables from diversion projects (cable diversion is required, for example, due to road works or building demolition). The waste is disposed in compliance with the National Environment Agency (NEA) requirements. To minimise fibre scrap generation, calculations are made to optimise the length of fibre cable required for each installation work.
Water management
Potable water is primarily used for operational needs and to cool our COs facilities. The used water is discharged as wastewater into the municipal sewerage system. While our water consumption is relatively low compared to other water-intensive industries, we acknowledge that water is an important and scarce resource in Singapore due to the country's limited freshwater resource. Besides daily inspection at our COs to ensure no water leakage, our chiller replacement initiative also take into consideration water efficiency in addition to energy efficiency.
Target:
- Maintain zero incidents of non-compliance with the relevant laws and regulations on waste disposal practices.
- Keep fibre scrapped within 2% of total fibre cable issued.
- Complete rectification of the water systems for five COs to meet PUB’s Water Efficient Building (Basic) Certification requirements.

Managing the supply chain and ensuring sustainability throughout the value chain are fundamental components of our decarbonisation efforts. We recognise that environmental and social impacts such as the depletion of natural resources, health impacts on workers due to exposure to hazardous materials and poor labour conditions can potentially arise at various stages of our supply chain, including the sourcing of raw materials, manufacturing processes, and the transportation of purchased fibre cables. The key stakeholders in NetLink’s supply chain include our fibre cable manufacturers and local contractors responsible for the construction and maintenance of NetLink’s fibre network infrastructure.
All our suppliers and contractors are required to abide by the Supplier Code of Conduct which includes clauses to minimise environmental and social impacts, such as compliance with environmental laws, upholding of human rights and prohibition of discriminatory practices. All suppliers and contractors must also abide by NetLink's zero-tolerance stance on corruption, the requirement to act ethically and observe all relevant laws and regulations in their operations.
Looking to the future, NetLink remains committed to deepening our engagement with suppliers, contractors, and customers of our COs, to gain a comprehensive understanding of our Scope 3 emissions and to explore ways to enhance sustainability throughout our supply chain.
Target: Conducting a trial for a potential energy-saving solution with our CO’s key tenant.
