Investment committees should ask whether climate risk is integrated into asset allocation decisions, how portfolio companies measure Scope 3 emissions, whether climate scenario analysis aligns with fiduciary duty, what governance oversees climate strategy, how manager selection incorporates climate competence, and whether transition financing is differentiated from divestment.
Investment committees increasingly face scrutiny over climate risk governance, emissions measurement, and long-term capital allocation in a decarbonising economy. Yet the frameworks, metrics, and governance structures remain contested. This brief outlines ten critical questions fiduciaries should resolve—and source evidence for—before committing capital or revising asset allocation policy.
Investment committees should ask whether climate risk is properly integrated into asset allocation decisions, how portfolio companies measure Scope 3 emissions, whether climate scenario analysis aligns with fiduciary duty, what governance structure oversees climate strategy, how manager selection incorporates climate competence, and whether transition financing is differentiated from divestment. These questions form the foundation of institutional climate governance.
Is climate risk integrated into our core asset allocation decision-making?
Many committees treat climate as a discrete ESG risk rather than a material driver of long-term returns. The distinction matters for fiduciary accountability. CalPERS, managing $440 billion in AUM, embedded climate scenario analysis into its asset-liability modelling following the 2015 Paris Agreement. Norges Bank, the $1.3 trillion Government Pension Fund of Norway, restructured its governance to assign board-level climate accountability alongside traditional risk management.
The question is whether your committee integrates climate into the investment policy statement, strategic asset allocation review, and manager mandates—or whether climate sits outside core capital allocation. Committees should request evidence: are climate scenarios stress-tested against target returns? Are equity allocations adjusted based on sector climate exposure? Do fixed-income strategies explicitly price transition risk?
Integration requires defining materiality thresholds. A committee managing $200 billion with 15% in fossil fuel-exposed equities faces different materiality than one with 2%. The question is not whether climate is material—regulatory and market evidence suggests it is—but how your specific portfolio concentrates climate risks and how those risks alter return assumptions.

How do we define and measure Scope 3 emissions across our portfolio?
Scope 1 and 2 emissions (direct and purchased energy) are increasingly standardised. Scope 3 (value chain emissions) remains contentious. A cement producer's Scope 3 includes customer use of its product; a bank's Scope 3 includes financed emissions across its loan portfolio. Measurement methodologies vary—some use spend-based approaches, others activity-based modelling—and disclosure quality remains uneven.
The CalSTRS investment team publishes annual portfolio carbon accounting, separating Scope 1, 2, and 3 totals. Yet CalSTRS acknowledges that Scope 3 estimates carry methodological uncertainty. Leading allocators now mandate Science Based Targets initiative (SBTi) alignment for portfolio companies as a proxy for Scope 3 discipline, rather than relying solely on self-reported carbon footprints.
Your committee should clarify: are you measuring Scope 3 at all? If yes, via which methodology—company disclosure, third-party provider estimates, or proprietary models? Are Scope 3 estimates weighted by relevance to your sectors? And critically, do you understand the error margins? An asset owner tracking 500+ holdings cannot audit every Scope 3 calculation.
Standardisation is improving. What Is IFRS S2? Climate Disclosure for Investors explains how IFRS S2 will harmonise climate reporting from 2024 onwards, reducing Scope 3 estimation variance—but implementation timelines remain staggered globally.
Does our climate scenario analysis inform strategic asset allocation?
Climate scenario analysis models portfolio outcomes under defined warming pathways. The Network for Greening the Financial System (NGFS) publishes aligned climate scenarios—1.5°C, 2°C, 3°C, and orderly/disorderly transition paths—used by central banks and major allocators. The question for your committee: does scenario analysis identify concentration risk in carbon-intensive assets? Does it quantify returns under various transition speeds?
The UK Pension Protection Fund, which manages £142 billion in liabilities, conducts regular climate value-at-risk analysis. It models asset valuations under different climate pathways and tests whether current allocation assumptions hold. This work informs engagement priorities and security selection.
Many committees run climate scenarios as a one-off exercise, then shelve findings. Leading practice integrates scenario results into annual asset-liability modelling and quarterly risk reporting. Committees should ask: Under a 2°C scenario, how does our equity allocation perform relative to 3°C? Which sectors show the largest valuation sensitivity? Are we hedging against faster-than-expected transition (energy decline) or slower transition (stranded asset risk)?
Scenario analysis also reveals second-order risks. A rapid energy transition may accelerate mineral demand (lithium, cobalt, nickel) and create commodity supply constraints. A committee should test whether climate-aligned tilts inadvertently concentrate mining and battery supply-chain risk.
What governance structure actually oversees climate strategy?
Governance clarity matters more than policy sophistication. Some committees assign climate oversight to a standalone ESG subcommittee; others embed climate into the main investment committee and risk committee. The structural choice affects decision velocity and accountability.
CalSTRS assigns board-level responsibility for climate governance to its Policy Committee, which oversees investment decisions. Climate analysis flows into the same governance cadence as equity and fixed-income strategy. Conversely, some public pensions assign climate to an ad-hoc advisory group, which reports annually but lacks decision authority.
Your committee should establish: Who owns climate policy? Is it the full board, a subcommittee, or the CIO? Are climate factors formally weighted in manager evaluations and proxy voting decisions? Does your governance structure allow climate-informed decisions to override legacy allocations? Or does climate sit outside the critical path for capital allocation?
Transparency requires publishing climate governance structures in annual reports. The 30 largest European pension funds increasingly disclose governance ownership; U.S. public pensions lag. Committees should clarify accountability: if climate risk materialises, who is accountable to beneficiaries?
How do we assess manager climate competence and integration?
Assets flow to managers with demonstrated climate governance. The Net Zero Asset Managers initiative (NZAMI) now includes 310+ signatories managing $67 trillion. Principles for Responsible Investment signatories exceed 5,500. But signatories vary vastly in capability.
Comittees should move beyond signature checks to examine manager evidence:
Governance structure: Does the manager have a board-level climate committee? Is climate analysis independent of sales? Are compensation incentives tied to climate integration?
Security selection: Does climate factor into valuation models? Can the manager articulate which companies are well-positioned for transition? Do they identify stranded asset risks across sectors?
Engagement: What is the manager's engagement record on decarbonisation? Does the manager actively participate in stewardship coalitions like Climate Action 100+?
Proxy voting: How does the manager vote on climate-related shareholder proposals? Is voting aligned with stated climate commitments?
Comittees should request manager climate scorecards, not marketing materials. Ask: Of your top 50 holdings, which face high transition risk? Which benefit from energy transition? How would your portfolio perform under a 1.5°C scenario? If managers struggle with these questions, climate integration is likely superficial.
Should we divest from fossil fuels or finance their transition?
This is a strategic fork with distinct fiduciary implications. Divestment exits positions in fossil fuel producers; transition financing provides capital for decarbonisation (renewable energy, grid modernisation, carbon capture). These are not synonymous, though some committees conflate them.
Divestment case: Fossil fuel companies face regulatory headwinds, declining long-term demand, and potential stranded assets. Exiting concentrates risk reduction in the present and transfers exposure to other investors.
Transition finance case: Some carbon-intensive companies (integrated energy majors, cement producers, heavy industry) are essential to decarbonisation pathways. They require capital for technology transition. Engagement and transition finance may generate returns while reducing portfolio emissions.
See Energy Security as an Investment Theme for Long-Horizon Allocators for how energy transition creates investment differentiation.
Comittees should clarify their theory of change. Are you divesting to reduce portfolio climate risk? Or are you seeking returns from transition-enabled companies? These imply different manager mandates and performance metrics.
Large allocators increasingly adopt hybrid approaches: divest from laggard fossil fuel producers, engage with transition leaders, and allocate growth capital to clean energy and grid modernisation. The UK's Universities Superannuation Scheme divested coal and oil sands, but retained diversified energy companies pursuing active transition. This reflects a risk-based rather than values-based approach.
Does our investment policy statement explicitly govern climate decisions?
Many committees lack explicit climate language in their investment policy statements (IPS). This creates ambiguity: are climate considerations discretionary or mandatory? Who arbitrates between return optimisation and climate risk reduction?
The IPS should clarify: climate risk is material to long-term returns and governance; climate factors inform manager selection and performance evaluation; climate scenario analysis informs strategic asset allocation; and climate transparency is required for all portfolio companies and asset managers. Without explicit language, climate decisions remain ad-hoc.
Leading institutions now bind climate governance into their core documents. CalSTRS, the UK Stewardship Code signatories, and the Institutional Investors Group on Climate Change all embed climate explicitly into governance frameworks. This signals to beneficiaries and stakeholders that climate is not optional.
How do we measure and benchmark portfolio climate performance?
Metrics matter for accountability. Committees should track: weighted average carbon intensity (emissions per unit of revenue or invested capital), carbon footprint relative to benchmark, Scope 1/2/3 exposure, transition risk concentration, and low-carbon asset allocation. These metrics enable year-on-year comparison and external benchmarking.
The Carbon Disclosure Project publishes annual portfolio carbon data for large institutional investors; Sustainalytics and MSCI offer carbon analytics platforms; and many allocators commission proprietary carbon accounting. The choice depends on transparency needs and analytical depth.
Comittees should establish climate performance metrics distinct from ESG ratings. A portfolio may score highly on ESG but carry high transition risk if concentrated in carbon-intensive sectors. Carbon metrics reveal this mismatch; ESG ratings often obscure it.
Benchmarking is critical. If your portfolio carbon intensity is 50% below your equity benchmark, that reflects tilt. If it's 5% below, climate policy is cosmetic. Transparent metrics prevent greenwashing claims and clarify actual climate positioning.
Are climate risks priced into our manager fees and performance expectations?
If climate risk is material, manager fees and performance targets should reflect it. Some committees still expect 7% real returns from equity allocations despite increasing climate valuation pressures on carbon-intensive sectors. This mismatch creates fiduciary risk.
Comittees should model return expectations under various climate scenarios and reset manager mandates accordingly. If your equity manager faces structural headwinds from energy transition, return targets and fees should adjust. Alternatively, if climate risks are overpriced, opportunistic positioning may enhance returns.
This is not about sacrificing returns for climate goals. It is about honest return expectations given climate realities. Committees that assume 2000-level energy sector returns in a 2030 transition scenario are not being rigorous.
What is our engagement strategy for climate-sensitive holdings?
Engagement differs from divestment. Active ownership—through proxy voting, shareholder resolutions, and direct management dialogue—can drive decarbonisation without exiting positions. The question is whether your committee has an engagement strategy or defaults to manager discretion.
Large allocators like Norges Bank, Canada Pension Plan Investment Board, and CalPERS publish engagement strategies: which companies face engagement on climate, what outcomes are expected, and when escalation to divestment occurs. This clarity enables accountability.
Comittees should ask: Do we have an engagement policy on climate for material holdings? Are we coordinating with peer investors via Climate Action 100+ or similar coalitions? Do we track engagement outcomes—behavioural change, capex reallocation, emissions reductions? Or are engagements performative?
How do we govern the risk of stranded assets and technological disruption?
Stranded asset risk—where assets lose value due to regulatory or technological change—is material in energy, transport, and real estate. Committees should assess: which portfolio companies face stranded asset risk under various climate scenarios? How concentrated is this risk?
This also intersects with broader technological disruption. The AI Infrastructure Investment Thesis for Long-Term Allocators outlines how digitisation and AI reshape energy demand and capital productivity. Committees must integrate climate risk with technology risk.
For instance, a portfolio heavily weighted to fossil fuel producers faces compounded risk: climate regulation reduces demand and stranded asset risk; simultaneously, AI-driven electrification accelerates the transition timeline. Committees should stress-test for combined scenarios.
Similarly, Digitisation as an Investment Theme for Asset Owners explores how digital infrastructure enables clean energy integration. Committees should identify where technology and climate risks interact—and where they create opportunity.
Implications for Long-Term Allocators
These ten questions do not prescribe climate policy—they clarify governance. Some committees will choose divest-first strategies; others will emphasise transition financing. The fiduciary obligation is to address climate risk systematically, transparently, and with explicit board accountability.
