Embedding ESG as Part of Our Investment Process

Sustained returns are built on strong and well-governed environmental, social, and economic systems. The investment decisions we make today are fundamental to shaping our portfolio’s resilience and the prospects of future generations.

We believe that companies that effectively address environmental, social, and governance (ESG) considerations are better positioned to mitigate risks and capture long-term value. ESG forms a core component of our investment framework and is embedded across the entire investment lifecycle — from pre-investment due diligence to post-investment engagement. This enables us to manage material risks, partner with our portfolio companies on ESG progress, and reinforce the resilience of our portfolio.

Our ESG framework guides the identification of material issues, integration of climate considerations, and ongoing engagement with portfolio companies. It is designed to:

  • expand business opportunities that deliver positive environmental or social outcomes;
  • strengthen ESG practices through pre-investment due diligence on material ESG issues and post-investment engagement;
  • manage exposure to companies with significant potential negative externalities; and
  • avoid investments in restricted industry sectors.

Our approach is rooted in our broader governance model, where we hold the boards and management of our portfolio companies accountable for the activities of their companies, but do not direct their day-to-day business decisions or operations.​

To support this, we employ tools such as our Climate Transition Readiness Framework and ESG Value Creation Playbook alongside sector- and issue-specific guidelines, to enhance decision making and engagement.

In line with our new organisational structure, our ESG integration priorities are being tailored to the mandates of the three portfolio segments, with a focus on materiality and driving sustainability outcomes across our diversified investment approach.

  • Singapore-based Temasek Portfolio Companies (TPCs): we are advancing ESG practices within TPCs, partnering them to enhance long-term resilience, competitiveness, and transition readiness.
  • Global Direct Investments (GDIs): we are identifying investments that have a growth trajectory in line with the Sustainable Living trend and integrating ESG in the assessment and stewardship of our investments.
  • Partnerships, Funds, and Asset Management Companies (PFAs): we are integrating ESG into our engagement with core fund managers, focusing on aligning ESG expectations for co-investments, and working with our main Asset Management Platform, Seviora Holdings, to develop ESG frameworks and integration approaches that fit our asset management companies.

Sustainability and Performance: A Dual Focus

Sustainable investing and long-term return generation are central to Temasek’s T2030 strategy. In early 2024, through an affiliated asset manager, we allocated capital to a global equity portfolio benchmarked to a global index to demonstrate that sustainability and long-term financial returns can reinforce each other over time.

Grounded in research by our quantitative strategy team, the strategy tilts toward companies with ESG characteristics linked to future equity outperformance, while keeping country and sector exposures aligned with the benchmark. The asset manager’s fundamental and ESG insights further sharpen stock selection and strengthen the portfolio’s ESG profile.

Since inception, the strategy has outperformed the global equity benchmark while maintaining comparable ESG ratings, improving controversy scores, and lowering carbon intensity. Despite a reversal in ESG sentiment and flows, performance was supported by our targeted ESG approach focused on return-relevant metrics rather than broad ESG tilts.

As we advance T2030, these encouraging results strengthen our conviction that sustainability and long-term returns can align.

Pre-Investment ESG Due Diligence

ESG analysis is integral to every investment proposal. Investment teams assess each opportunity against a set of core ESG topics — including climate change, social compliance, and governance — complemented by assessments of sector‑specific material topics. Peer benchmarking and forward-looking sustainability trends further inform our view of risks and opportunities. These insights are considered in our investment committee deliberations.

Our in-house ESG specialists support this process, and external experts are engaged for deep dive assessments where needed.

Pre-investment due diligence also informs our post-investment priorities for transactions where we hold a material stake. For example, our due diligence of an apparel company identified opportunities to strengthen its supply chain management, particularly amidst tightening local regulations. The company recognised these areas for improvement and agreed to undertake a holistic review of its supply chain practices, with the aim of advancing towards industry best practice.

Environmental Assessment

Climate analysis is applied for all new investments and includes:

  • evaluating a company’s carbon footprint;
  • assessing physical and transition risks; and
  • identifying climate-related opportunities driven by technology, regulation, and market shifts.

We apply a suite of metrics to quantify climate-related exposures and inform decision making. We also conduct climate value impact assessment, estimating potential asset‑level valuation impacts under different climate scenarios. This assessment encompasses potential impacts from acute and chronic climate risks, including implications for operations, assets, and critical supply chains.

In consideration of the rapid degradation of ecosystems with resulting impacts on natural capital and ecosystem services, our biodiversity risk assessment tool identifies potential interfaces between assets and ecologically sensitive areas where material.

Where environmental risks are deemed material, we evaluate the company’s ability to mitigate or adapt to these risks.

Social Baseline Risk Assessment

Social baseline risk assessments are conducted for all new direct investments. Through these assessments, we evaluate companies’ baseline practices across key social topics, including human rights, labour standards, and workplace safety. This assessment is complemented by a broader analysis of social issues through a materiality lens. Where gaps or potential concerns are identified, we undertake deeper due diligence. We also continue to strengthen our internal capabilities in assessing social issues through enhanced guidance and training.

The social baseline risk assessment supports the early identification of social red flags that may require deeper review and post-investment follow-up. For example, during pre-investment due diligence on a manufacturing company, we identified instances of non-compliance relating to wages, working hours, and health and safety standards across its factories. Corrective actions were identified and shared with the company to facilitate remediation.

Governance Considerations 

Robust governance is foundational to a resilient and trustworthy organisation. As part of our due diligence, we review oversight structures, the company’s approach to ESG governance — including climate — and the adequacy of policies for transparency and regulatory compliance.

Recognising the importance of a human-centred Artificial Intelligence (AI) approach as the technology rapidly evolves, we also perceive AI ethics and governance as critical for investments where AI technology is being developed and deployed. We adopt a risk-based tiered approach to assess and evaluate responsible AI practices, and keep ourselves abreast of the latest regulatory and industry developments to ensure our approach is fit-for-purpose.

ESG Due Diligence and Engagement in Practice

The logistics and transport infrastructure sector is inherently exposed to material ESG risks due to its asset-heavy operations, emissions-intensive footprint, and reliance on large workforces and contractors. In a recent transaction, Temasek considered a potential investment in an integrated logistics player operating assets across ports, terminals, and transportation. The transaction was led by an experienced infrastructure sponsor, who commissioned third-party ESG due diligence as part of the investment process.

In line with our ESG due diligence approach, we adopted a financial materiality lens in identifying ESG issues. We further assessed whether the sponsor’s scope adequately covered these areas and where additional diligence might be needed.

Climate and decarbonisation emerged as a core ESG issue given the hard-to-abate nature of logistics and transport operations, the significant Scope 1 emissions, and the initial lack of clarity on how the company’s publicly stated targets would be achieved. This led us to probe the credibility of transition levers, capital allocation, management accountability, and whether decarbonisation would be embedded into the post-investment work plan. Worker health and safety, particularly contractor safety, was another priority given sector risk and historical incidents.

The diligence findings confirmed that the company had well-established governance structures and strong board oversight of traditional ESG risks.

It had articulated long‑term climate ambitions and initiated transition planning, including preliminary emissions reduction targets and technology trials. However, decarbonisation initiatives were still at a relatively early stage and largely restricted to site-specific initiatives, with limited evidence on decarbonisation pathways, capital allocation, and how climate considerations would be embedded into enterprise risk management and incentives. There is potential to further formulate a more structured and holistic approach to managing transition risk. This reinforced the importance of post‑investment measures to translate ambition into execution, particularly in a sector facing increasing regulation, cost, and customer expectations associated with decarbonisation.

On the health and safety front, the company demonstrated strong performance in management systems, supported by board oversight and improving safety metrics. Nevertheless, the inherent risk profile of the sector and the reliance on contractors underscored the need for continued focus on consistent implementation and ensuring health and safety outcomes across the supply chain.

The sponsor’s commitment to working with the company on the identified areas of improvement was an important consideration in giving us confidence that the company will continue to make progress on its material ESG topics. The sponsor committed to an ambitious climate target, supported by a fully costed business plan containing specific decarbonisation projects that will be integrated into the divisional budgeting process, incentive plans, and key performance indicators. Safety management will also be further reviewed using a structured framework to drive improvements.

The diligence findings, alongside the post-investment priorities and timelines, have been documented in our investment committee materials for accountability. We plan to follow up with the sponsor on a quarterly basis and at annual board meetings to track the progress of ESG initiatives.

Portfolio Monitoring

We monitor ESG risks and performance across the portfolio through multiple channels:

  • ESG Risk Monitoring: regular monitoring of material ESG issues in portfolio companies, coupled with annual reporting to Board and senior management on overall key ESG risk areas.
  • Climate Risk Modelling: scenario-based assessments for listed and significant unlisted holdings.
  • Carbon Budget: emissions budget supported by an in-house carbon analytics platform and dashboards to enhance insights and alignment with our portfolio emissions reduction goals.

These efforts support proactive risk management and help identify emerging opportunities linked to sustainability trends.
