A guide to MAS environmental transition planning for fund managers
- Apr 23
- 4 min read
The Monetary Authority of Singapore (MAS) has strengthened its expectations for environmental risk management in the asset management sector. Its original Guidelines on Environmental Risk Management for Asset Managers required firms to embed environmental risk into governance, investment, risk management, stewardship, and disclosure. MAS has now gone further by issuing new transition-planning guidelines in March 2026, which will take effect from September 2027 following an 18-month transition period.
For Licensed Fund Management Companies (LFMCs), this is not simply an ESG enhancement. Environmental and climate-related risk is now treated as a core fiduciary and business concern. The key question is no longer whether a firm has an ESG policy, but whether environmental and climate-related considerations demonstrably influence decisions and oversight in practice.
This article outlines the key considerations for fund managers and five practical steps to help firms respond.
At a glance
Fund managers should focus on five immediate priorities:
Strengthen board and senior management oversight
Embed environmental and climate-related risk into investment processes
Update risk frameworks to address both transition and physical climate risks
Tighten oversight of delegated functions and third-party providers
Align environmental and climate-related disclosures with actual practices
What MAS has introduced
MAS’s existing Guidelines on Environmental Risk Management for Asset Managers set expectations across five areas: governance and strategy, research and portfolio construction, portfolio risk management, stewardship, and disclosure. These apply proportionately to fund managers based on the size, nature, and complexity of the firm’s activities.
The March 2026 transition-planning guidelines build on this foundation, shifting the focus toward forward-looking implementation. Environmental risk is no longer viewed as a static compliance exercise, but as a dynamic factor that should influence strategy, portfolio construction, and ongoing risk oversight.
What the 2026 transition-planning update adds
The latest guidelines introduce more explicit expectations around transition planning and forward-looking climate risk management.
In particular, fund managers are expected to:
Adopt a forward-looking approach
Move beyond purely point-in-time or backward-looking assessments to consider how portfolios may be affected under different climate transition scenarios.
Assess both transition and physical risks
This includes policy, regulatory, technology, market and consumer shifts (transition risks), as well as acute and chronic climate impacts (physical risks) arising from climate change.
Integrate climate considerations into decision-making
Climate-related risks should be reflected in business strategy, investment due diligence, portfolio construction, and ongoing monitoring - not treated as a separate overlay.
Demonstrate active stewardship
MAS places greater emphasis on engagement with investee companies in a risk-proportionate manner as part of transition planning, rather than relying solely on exclusion or divestment.
The guidelines take effect from September 2027, providing an 18-month transition period. However, firms should expect increasing supervisory focus during this period, particularly where gaps are evident.
What this means for fund managers
For fund managers, MAS’s updated expectations translate into practical changes across the organization.
Governance must be active and accountable
Environmental and climate-related risk should be owned at board and senior management level, with clear accountability, reporting lines and escalation processes. Passive oversight is unlikely to be sufficient.
Investment processes must demonstrate real integration
Firms should be able to demonstrate how environmental and climate-related factors influence actual decisions. For example:
Investment committee papers may include climate-related risk considerations or scenario analysis
Due diligence frameworks may incorporate sector-specific transition or physical risks
Portfolio monitoring may track climate-related exposures over time
A purely qualitative or box-ticking approach is unlikely to meet expectations.
Risk frameworks must evolve
Existing risk systems should be reviewed to assess whether they capture:
Forward-looking transition risks
Physical climate exposures
Concentration risks linked to vulnerable sectors, geographies, or business models
Resilience of portfolios under different climate-related scenarios, where material
Even under a proportionate approach, firms should be able to evidence a structured methodology.
Delegation does not remove responsibility
Where functions such as investment management or ESG analysis are outsourced, accountability remains with the fund manager. This includes:
Clear contractual expectations
Ongoing monitoring and reporting
Periodic due diligence on service providers
Disclosures must reflect reality
As regulatory and investor expectations increase, inconsistencies between environmental or climate-related disclosures and actual practices may create both regulatory and reputational risk. Disclosures should be supported by robust internal processes, governance, and data.
Five practical steps fund managers can take now
Step 1: Conduct a gap assessment
Start by reviewing current governance, investment processes, risk frameworks, and disclosures against MAS expectations to identify gaps and prioritize remediation efforts.
Step 2: Clarify governance and accountability
Define and document roles and responsibilities for environmental and climate-related risk management. Ensure senior management oversight is clearly evidenced, with appropriate reporting and escalation mechanisms.
Step 3: Embed environmental and climate-related risk into investment workflows
Update due diligence templates, investment committee materials, and portfolio construction and monitoring processes to ensure environmental and climate-related considerations are consistently and meaningfully incorporated.
Step 4: Strengthen oversight of delegated functions
Confirm that expectations for third-party providers are clearly defined and supported by ongoing monitoring, reporting, and periodic review.
Step 5: Review disclosures before regulatory expectations tighten further
Assess whether environmental and climate-related disclosures are evidence-based, internally consistent, and capable of withstanding regulatory and investor challenge.
Key implementation challenges
While expectations are clear, implementation may present practical challenges, including:
Data availability and quality for climate-related metrics
Reliance on third-party ESG or data providers, requiring robust validation and oversight
Integration into existing systems and workflows, particularly for smaller firms
MAS allows flexibility based on a firm’s size and complexity, but a structured approach is still expected.
Outlook
Environmental risk management and transition planning are becoming a central component of MAS supervision. Firms should expect these areas to be increasingly incorporated into regulatory reviews and inspections.
While the September 2027 deadline provides time, implementation will require coordinated changes across governance, investment, risk, and operations. Firms that act early will be better positioned not only for compliance, but also for resilience in an evolving investment environment.
