StarHub cinches its first A in CDP climate assessment
This A rating CDP’s 2025 Climate Change Assessment reflects growing momentum in emissions management and renewable energy, as StarHub advances toward its 2030 milestones and longer-term 2050 net-zero target.

StarHub has received an A ranking in the CDP’s 2025 Climate Change Assessment, the highest climate score the company has achieved to date. The result reinforces its sustainability credentials following its recognition in 2024 and 2025 as one of the world’s most sustainable wireless telecommunications companies. Starting the year with this rating, it seems that StarHub is intent on sustaining that standing, as it works towards its longer-term goal of achieving net-zero emissions by 2050.
The assessment is conducted by CDP, a global non-profit organisation that operates one of the world’s most widely used environmental disclosure platforms. CDP collects climate-related data from organisations and evaluates them on how comprehensively they measure, manage and reduce their environmental impacts. Its climate change grading ranges from D to A, with an A indicating leadership in governance, risk management and demonstrable action.
Beyond benchmarking performance, the assessment process is designed to help organisations better understand their environmental dependencies, identify inefficiencies and receive actionable insights to reduce emissions, long-term risk and avoidable costs.
Within this context, StarHub’s A ranking suggests that it is managing climate-related risks and opportunities well. This is particularly notable given the nature of its business; telecommunications rely heavily on energy-intensive infrastructure, such as networks, data centres and digital systems. Historically, this has meant significant dependence on fossil fuels.
Therefore, as energy prices fluctuate and fossil fuel supply dwindles, year by year, lessening carbon emissions is something of a byproduct of reducing business risks. Over the past year, StarHub has sharpened its focus on embedding climate considerations into core business decisions. The company has outlined efforts to lower emissions across Scopes 1, 2 and 3, supported by measures such as enhanced energy monitoring and the progressive retirement of legacy systems. Through these methods, StarHub is able to improve its energy efficiency, lessening its need for electricity.
The company is increasing its adoption of renewable energy. After all, renewable energy is widely viewed as carrying lower long-term supply risk and is fairly affordable, especially as its production increases.
Beyond its direct services, StarHub has also been working to reduce emissions across its wider operations. This includes exploring cleaner mobility options and strengthening emissions management across its supply chain.
In that vein, a key contributor to its improved CDP score seems to be its reduced Scope 3 emissions, which encompass indirect emissions generated upstream and downstream of the company’s operations. These emissions are often the most challenging to address, as they depend heavily on supplier cooperation and data transparency.
To that end, StarHub has increased data collection across its value chain and engaged more closely with suppliers to obtain more comprehensive emissions information. It has also developed a decarbonisation and supplier engagement roadmap anchored in science-based principles, providing clear guidelines for its partners.
The A ranking also aligns with StarHub’s future goals. By 2030, the company aims to reduce absolute Scope 1 and 2 emissions by 50%, cut Scope 3 emissions by 25%, and achieve a 30% renewable energy share. These goals serve as milestones towards its ultimate target of net-zero emissions by 2050.
Taken together, the CDP assessment suggests that StarHub has been translating its sustainability commitments into action. Having already received recognition in recent years, its achievements underscores its efforts to maintain that position as climate performance becomes an increasingly important measure of corporate resilience and credibility.
