StarHub earns first CDP ‘A’ for climate risk strategy
StarHub has received an 'A' rating in CDP's 2025 Climate Change Assessment, the first time the Singapore telecoms group has secured the top score in the disclosure scheme.
The company said the result marked its highest climate score to date. It also places StarHub in a smaller pool of organisations recognised by CDP for their approach to climate-related disclosure and management of risks and opportunities.
Telecoms operators run networks and data centres that consume significant electricity. StarHub said it has taken steps across its infrastructure and operations that relate to energy use, renewables, transport and supply chain emissions.
Operational changes
StarHub pointed to energy efficiency work across network sites and data centres. The company cited monitoring, virtualisation and the retirement of older systems as part of that work.
It also flagged renewable energy adoption. StarHub said this includes renewable electricity purchases and installing solar generation at its facilities.
The company said it is progressing fleet and operations decarbonisation. It described this as a move towards cleaner mobility options. It also said it is strengthening emissions management across its supply chain.
Scope 3 focus
StarHub said improvements in data collection and value chain engagement contributed to the 'A' rating. The company described closer collaboration with key suppliers and a shift towards "bottom-up, activity-based emissions information".
StarHub said it refined datasets across its most material Scope 3 emissions categories. It also said it strengthened the quality of its disclosures.
The company said it has a decarbonisation and supplier engagement roadmap that follows science-based principles. It said this roadmap guides emissions reduction ambitions towards 2030 and 2050.
Disclosure and targets
StarHub said its approach has shifted from meeting disclosure requirements to strengthening how climate risks, emissions and targets are measured and managed. It said this work now forms part of everyday operations and longer-term planning.
It also said it has shown closer alignment between emissions performance and its science-based targets. StarHub said it continues to disclose progress and challenges.
CDP runs an environmental disclosure system used by companies, cities, states and regions. It also provides data used by financial institutions in investment and lending decisions. CDP said it aligns with the ISSB climate standard IFRS S2 as a baseline.
StarHub linked the rating to actions already under way in its energy procurement. In 2024, the company introduced long-term Power Purchase Agreements for renewable energy, it said.
StarHub said further details sit in its Sustainability Report 2024 and Climate Transition Plan. The company said it plans to publish its 2025 Sustainability Report in April 2026.
