Case study question: use of sustainable and responsible investments


Hugh is an investment adviser at FHF, a fund management firm that manages a pension portfolio for Big plc. Hugh typically deals with Anita, the head of the trustee board at Big plc, and also works with Big’s finance director, James, as well as Martina at Big’s actuarial consultants, AC Partners. Big plc operates a number of pension schemes for staff, some are defined contribution (DC) schemes and others are defined benefit (DB) schemes. At Big plc, new staff are able to join the DC scheme, but there are a large number of members in the DB scheme, including active and deferred members, and members with pensions in payment. FHF manages the portfolio for Big’s DB scheme. In previous discussions, Martina has explained the asset allocation and benchmark that Anita has adopted, as advised by AC Partners, in order to meet the current and future projected liabilities for the DB scheme. These include estimated inflation, returns across a number of asset classes, equity dividend projections, interest rate expectations, member profiles and mortality rate estimates. At the most recent actual valuation, assets were 99% of liabilities.
 
Anita has contacted Hugh, since one of the DB scheme deferred members has contacted the trustees to ask how the scheme is managing climate risks in the pension fund and is suggesting that the scheme’s portfolio should be fossil fuel divested to better manage ‘stranded asset risk’. Anita initially passed the enquiry to one of Big’s pension relationship team, suggesting that they send a standard (‘do nothing’) reply letter. To her surprise, her junior colleague returned a few days later to explain that the deferred member making the enquiry had been one of Big’s technical specialists and their file showed they had an advanced degree in climate sciences. Her colleague wondered whether this might mean the deferred member’s enquiry should be treated differently. Anita followed this up with conversations with James and Martina. James expressed concerns that any change in investment policy might result in portfolio underperformance, with the result that Big plc would have to top up the scheme, which is already underfunded. Martina explained that the trustees’ fiduciary responsibility was to the scheme members as a whole and not to any one member or their individual investment preferences, therefore no change was required to the scheme asset allocation, benchmark or investment policy. While Anita thinks this sounds reasonable, she thought she would seek Hugh’s input. Which of the following would be Hugh’s best recommendation to Anita?
1. James and Martina’s advice is entirely correct. The scheme should be managed for the benefit of members as a whole. While the portfolio does not currently manage climate risk, the fund manager keeps abreast of developments, and there is no need for any action. The trustees do not need to respond to enquiries from individual scheme members. It is not their duty to invest the portfolio to meet individual member’s personal preferences.
2. James and Martina’s advice is entirely correct. The scheme should be managed for the benefit of members as a whole. While the portfolio could be managed sustainably to help manage climate risks, this could result in a risk of underperformance. The fund manager keeps abreast of developments, and it would be wisest to make no changes in the investment policy as advised by their actuarial consultants.
3. James and Martina’s advice is not entirely correct. Trustees are recommended to explain how they manage climate risk, and there is no clear evidence that incorporating sustainability considerations necessarily undermines long-term risk-adjusted performance. While the scheme should be managed for the benefit of members as a whole, trustees should respond to credible enquiries by scheme members. As Big acknowledges, the deferred member was one of their technical experts with qualifications in the climate sciences, the ‘person on the street’ might feel that such an enquiry was not ‘frivolous’. There is more than one way of managing climate risk; fossil fuel divestment is one option, but others should also be considered. (CORRECT)
4. James and Martina’s advice is not entirely correct. The trustees have a responsibility to ensure the portfolio should be managed sustainably to address climate risk, and there is no evidence that a sustainable investment policy would undermine long-term performance. Since the member was one of Big’s technical experts, and qualified in climate sciences, the ‘person on the street’ would feel that such an enquiry was not ‘frivolous’. Therefore, Anita should take the enquiry seriously, the scheme should revise its investment policy and fossil fuel divest.








Case study explanation: use of sustainable and responsible investments


Option one is wrong. Yes, the scheme should be managed for the benefit of members as a whole. While it is not the duty of trustees to invest to meet individual members’ personal preferences, they should respond to credible enquiries by scheme members. As the deferred member does appear to at least understand climate science (even if, maybe, not investment), the ‘person on the street’ might feel their enquiry credible. The fund manager ‘keeping abreast of developments’ is not the same as managing the portfolio sustainably. If (as the scheme member asks) there is a risk that fossil fuel-related investments the scheme holds could become ‘stranded assets’, any market move could easily occur more quickly than the manager could respond.


Option two is wrong. Yes, the scheme should be managed for the benefit of members as a whole. While it is not the duty of trustees to invest to meet individual members’ personal preferences, they should respond to credible enquiries by scheme members. As the deferred member does appear to at least understand climate science (even if, maybe, not investment), the ‘person on the street’ might feel their enquiry credible. There is a good deal of evidence that sustainably managed portfolios would not be expected to underperform, particularly over the longer-term, which is likely to be relevant in this case, as it is a pension fund. The fund manager ‘keeping abreast of developments’ is not the same as managing the portfolio sustainably. If (as the scheme member asks) there is a risk that fossil fuel-related investments the scheme holds could become ‘stranded assets’, any market move could easily occur more quickly than the manager could respond.


Option three is correct. The Pensions and Lifetime Savings Association’s (PLSA) Statement of Investment Principles recommends that governance bodies should set out how they believe climate change relates to their investment strategy and how they are mitigating climate change-related risk, and should proactively seek low-carbon investment options. There is a good deal of evidence that sustainably managed portfolios would not be expected to underperform, particularly over the longer-term, which is likely to be relevant in this case, as it is a pension fund. While it is not the duty of trustees to invest to meet individual members’ personal preferences, they should respond to credible enquiries by scheme members. As the deferred member does appear to at least understand climate science (even if, maybe, not investment), the ‘person on the street’ might feel their enquiry credible. Climate risk can be managed by a range of investment policies, which do include fossil fuel divestment, but other approaches would include ESG integration and investment in renewable energy, for example.


Option four is wrong. Although the PLSA Statement of Investment Principles recommended that governance bodies should set out how they believe climate change relates to their investment strategy and how they are mitigating climate change-related risk, this is not necessarily as strong as a ‘responsibility’. It is correct that there is a good deal of evidence that sustainably managed portfolios would not be expected to underperform, particularly over the longer-term, which is likely to be relevant in this case, as it is a pension fund. While it is not the duty of trustees to invest to meet individual members’ personal preferences, they should respond to credible enquiries by scheme members. As the deferred member does appear to at least understand climate science (even if, maybe, not investment), the ‘person on the street’ might feel their enquiry credible. As the deferred member may not understand investments, and there are other approaches possible, it would not be appropriate to jump straight to fossil fuel divestment without further consideration.

Case study question: DC trustees and scale‑up investment in sustainability‑focused businesses


You are a trustee of the Horizon FutureSave DC Pension Scheme, a UK‑based scheme with 40,000 members and £1.8bn in assets. The default strategy is a diversified, largely liquid, multi‑asset fund run by an external manager, with some ESG integration and exclusions but no significant allocation to illiquid assets.


The trustees are considering a proposal to allocate up to 5 to 10% of the default fund over time to scale‑up (post‑venture, pre‑IPO) companies operating in sustainability‑related sectors, such as energy‑efficiency technologies, grid and storage solutions, circular‑economy and waste‑reduction platforms, and sustainable agriculture and food systems.


The driver is two‑fold:


* a belief that scale‑ups in the sustainability field can deliver attractive long‑term returns and diversification, and  
* a desire to support the transition to a lower‑carbon, more resource‑efficient economy, in line with the scheme’s net‑zero and stewardship commitments.


However, trustees are acutely aware that:


* DC members bear investment risk individually;  
* illiquid and early‑stage companies carry higher risk and weaker data;  
* regulatory expectations around value‑for‑money, greenwashing and suitability are tightening.


The question before the board is: What is the best approach for trustees to take when considering such a move, in terms of gathering and assessing the available data and making their decision?


After initial discussions with advisers, four broad “paths” are outlined.


Path A: Marketing‑led “impact story” with limited diligence


The trustees are presented with a glossy proposal from a single private‑markets manager. The pitch emphasises 
 case studies of successful sustainability scale‑ups; alignment with SDGs and national industrial strategies; and strong impact narratives and photographs of projects and communities.


The manager provides high‑level target returns (an IRR, internal rate of return, of 10–12%) and states that “all investments are aligned with net‑zero and EU Taxonomy‑compliant”, but offers limited detail on:


   * pipeline quality and diversification,  
   * historic track record through different cycles,  
   * risk controls and liquidity management,  
   * specific methodologies for impact and climate measurement.


Trustees are attracted by the narrative appeal and the apparent simplicity of delegating to a single “specialist impact partner”. They consider relying largely on the manager’s marketing materials and a short adviser note summarising key points, without commissioning further independent analysis or structured due diligence. No specific plan is made to integrate member views or to stress‑test liquidity and value‑for‑money outcomes.


Path B: In‑house qualitative judgement based on public information


Concerned about conflicts of interest in manager pitches, the trustees decide to have the in‑house pensions team and investment sub‑committee review public information on a selection of sustainability‑themed scale‑ups and funds (websites, press coverage, award listings, basic financials where available); discuss opportunities and risks qualitatively at board meetings; and rely on their own judgement and “common sense” to choose one or two managers that “feel right”.


The scheme does not:


   * systematically collect or analyse data on risk/return characteristics, volatility, liquidity, or failure rates in the relevant segments,  
   * carry out a formal manager search using a structured request for proposal (RFP) and scoring process, or  
   * obtain specialist input on private‑markets due diligence, legal terms, or ESG/impact measurement frameworks.


The trustees document their reasoning in broad terms (“we believe this sector offers long‑term potential and aligns with our sustainability beliefs”) but without detailed quantitative analysis, scenario testing or member outcome modelling.


Path D: Structured, evidence‑based process integrating financial, sustainability and member‑outcome data


The trustees, working with their investment consultant and legal advisers, design a multi‑step process before making any commitment. The process includes:


1. Clarifying objectives and constraints  
   * Articulate clearly what the trustees are trying to achieve:  
      * financial: expected risk/return profile, diversification benefits, time horizon, fee tolerance;  
      * sustainability: contribution to net‑zero and broader environmental/social outcomes; and
      * member outcomes: impact on projected retirement pots, volatility, and value‑for‑money in the default.  
   * Confirm regulatory and fiduciary context (eg UK DC value‑for‑money framework, illiquids guidance, stewardship code expectations).


2. Gathering and analysing market and risk data  
   * Commission the consultant (or an independent private‑markets specialist) to provide:  
      * empirical data on returns, volatility and loss rates for comparable scale‑up and growth‑equity strategies;  
      * analysis of liquidity implications, including:  
      * expected capital‑call and distribution profiles;  
      * potential need for secondary sales in stressed markets;  
      * interaction with daily‑dealing DC structures and platform constraints;  
      * scenario analysis of how a 5–10% allocation could affect member outcomes under different market conditions.  
   * Review available benchmarking and peer practice (eg how other DC schemes have approached similar allocations, including any regulatory commentary).


3. Designing a manager search with clear criteria  
   * Run a competitive search with a formal RFP that requires candidates to provide:  
      * detailed track records (gross and net of fees), attribution, and evidence of value creation in scale‑up, not just venture or buy‑out;  
   * robust ESG and impact frameworks, including:  
      * use of recognised standards (eg SFDR Article 8/9, EU Taxonomy, SFDR PAIs, ISSB/TCFD alignment where relevant);  
      * policies and processes for Scopes 1 to 3 GHG estimation and reduction at portfolio‑company level;  
      * clear impact theses, KPIs and reporting frequency; and 
      * information on governance, key‑person risk, fee structures, alignment of interest, and risk management.  
   * Score managers against pre‑agreed criteria covering:  
      * financial performance and risk;  
      * quality and credibility of sustainability/impact approach and data; and
      * operational robustness and reporting capabilities.


4. Assessing data quality and auditability  
   * Require shortlisted managers to explain:  
      * how they collect and verify ESG and climate data from portfolio companies;  
      * what proportion is reported vs estimated;  
      * how they ensure data quality over time (eg, controls, third‑party verification, readiness for assurance); and
      * how their reporting will support the scheme’s own TCFD/ISSB‑aligned disclosures.  
   * Ensure that reporting will allow trustees to:  
      * track both financial and sustainability KPIs at portfolio level;  
      * evidence that members’ money is being used consistently with the scheme’s net‑zero and stewardship commitments; and
      * integrate the allocation into overall climate and ESG metrics (eg Scopes 1–3, alignment assessments).


5. Member and regulatory considerations  
* Consider whether and how to seek member views (eg through surveys or targeted engagement) on illiquid and sustainability‑focused investments, especially given the long time horizon and higher risk profile.  
* Ensure communications are clear, fair and not misleading:  
   * avoid over‑promising “impact”; and
   * explain illiquidity, risk and time horizon in accessible terms.  
* Check alignment with evolving UK guidance on DC illiquids, value for money and sustainable investment.


6. Decision and monitoring framework  
   * Make a documented decision, summarising:  
   * why the chosen approach is in members’ best financial interests;  
   * how sustainability considerations have been integrated in line with fiduciary duties; and
   * how data and reporting will support ongoing monitoring.  
   * Set expectations for regular reporting (eg quarterly financial and annual impact/climate reports) and define triggers for review or escalation.


The trustees accept that data from scale‑ups will not be perfect, but insist on:


   * transparency of methods and limitations,  
   * minimum standards for ESG/climate/impact data collection, and  
   * a pathway toward assurance‑ready information over time.


Path D: “Wait and see” with no preparatory work


Concerned by complexity and reputational risk, the trustees decide to:


   * postpone any decision on scale‑up allocations until the regulatory picture and market practice are “more settled”,  
   * maintain the current liquid multi‑asset default with limited exposure to private markets or direct sustainability scale‑ups, and  
   * make no particular effort to build internal understanding of private‑markets sustainability data or to engage with industry initiatives on DC illiquids.


They reason that “doing nothing new” is safer from a regulatory standpoint and requires no significant investment in new data, systems or advisor relationships.


Question: which path represents the best approach for DC trustees considering an increased allocation to sustainability‑focused scale‑up businesses, in terms of gathering and assessing data and making a defensible decision?


A. Marketing‑led “impact story” with limited diligence  
B. In‑house qualitative judgement based on public information  
C. Structured, evidence‑based process integrating financial, sustainability and member‑outcome data  
D. “Wait and see” with no preparatory work


Correct answer: Path C


Why Path C is the correct route. It is the only approach that is consistent with fiduciary duty in a DC context.


Trustees must act in members’ best financial interests, which includes:  


   * understanding risk/return and liquidity implications;  
   * considering value‑for‑money and retirement outcomes, not just headline returns;  
   * ensuring any sustainability objectives are pursued within that framework.  
  
Path C explicitly models member outcomes, stress‑tests liquidity and examines

Case study question: transition finance in steel production
Paternoster Steel is a large, listed European producer with blast‑furnace‑based operations and emissions of roughly two tonnes of CO₂ per tonne of steel. Under investor pressure and in a jurisdiction tightening carbon pricing, it proposes a “transition financing” package to support its 2035 target of cutting emissions intensity by 55% versus 2020 levels and achieving net‑zero by 2050. The company needs €2 billion over five years for a mix of capacity expansion, incremental efficiency measures and a pilot green‑hydrogen direct‑reduced iron (DRI) plant.


From the perspective of investors and lenders, the key questions are whether the financing is credibly aligned with a science‑based pathway for steel, and how risks and returns should be shared. Four structures are tabled.


Path A: A plain‑vanilla corporate bond, marketed as a “transition bond”, with proceeds fungible across the business and no specific covenants or KPIs. Management argues that any capital supports the long‑term transition because it strengthens the balance sheet. This fails the credibility test: there is no guarantee the funds will go to decarbonisation capex rather than life‑extending investment in high‑emitting assets, and no measurable link between the instrument and the transition plan.


Path B: A use‑of‑proceeds “transition bond” whose framework allows a broad list of projects: energy‑efficiency upgrades to existing blast furnaces, minor waste‑heat recovery investments and general maintenance, alongside the DRI pilot and electrification of certain processes. While this is an improvement, the eligibility criteria are still too loose. A significant share of proceeds could be allocated to marginal efficiency gains that reduce short‑term costs but risk locking in blast‑furnace capacity well beyond what a 1.5–2°C steel pathway allows.


Path C: A sustainability‑linked loan tied to a single KPI: a 55% reduction in emissions intensity by 2035, with a one‑time margin step‑up if the target is missed. Here, the company’s overall trajectory is at least contractually embedded, but the structure is weak. The long‑dated KPI provides little discipline in the crucial next decade, there are no interim milestones, and the financial incentive is modest compared with the scale of capex and transition risk. It also does not differentiate between decarbonisation driven by genuine technology shifts and that achieved through changes in the product mix or divestments.


Path D: This approach combines a tightly defined use‑of‑proceeds bond with a parallel sustainability‑linked revolving credit facility. The bond framework restricts eligible projects to the DRI plant, associated renewable power PPAs, electrification of specific process lines, and the decommissioning or conversion of one blast furnace by an agreed date. The sustainability‑linked facility embeds short‑ and medium‑term, independently validated emissions‑intensity targets for 2028 and 2032, aligned with a sectoral 1.5–2°C pathway. Margin step‑ups and step‑downs are meaningful, calculated over the life of the facility, and accompanied by annual reporting and external verification. Both instruments reference a published transition plan that sets out capex, technology choices and asset‑retirement schedules.


Which path is the most credible transition finance structure?


A: plain‑vanilla corporate bond
B: use‑of‑proceeds “transition bond”
C: sustainability‑linked loan
D: use‑of‑proceeds bond


Case study answer
The fourth structure, deploying use-of-proceeds bonds, is the right solution. It directs capital to clearly transitional assets, avoids financing lock‑in of incompatible capacity, and ties general corporate liquidity to a transparent, time‑bound decarbonisation pathway with material financial consequences for under‑ or out‑performance. For lenders and investors, it improves visibility on transition risk, supports alignment with portfolio climate targets and offers upside if Paternoster Steel successfully pivots to low‑carbon production. For the company, it secures funding at competitive rates while reinforcing the credibility of its strategy in the eyes of regulators, customers and capital markets.


Path A, B and C are all problematic because they do not give investors sufficient confidence that their capital is genuinely, measurably supporting a 1.5–2°C‑aligned transition of the steel business, or that transition risks are being properly managed and shared.  


Path A – Plain‑vanilla “transition” corporate bond


* No ring‑fencing of proceeds: Funds are fungible across the business. There is no assurance that the €2 billion will finance decarbonisation capex rather than life‑extending investments in blast furnaces or other high‑emitting assets.  
* No KPIs or covenants: The structure does not embed any climate‑related performance requirements (eg interim emissions‑intensity targets, asset‑retirement commitments). Labelling it “transition” is therefore largely cosmetic.  
* No measurable link to a science‑based pathway: Investors cannot demonstrate that this instrument is aligned with a Paris‑aligned steel pathway, which undermines both credibility and usability for climate‑constrained portfolios.


In short, Path A invites “transition‑washing”: a conventional bond with a green‑sounding label but no substantive accountability.


Path B – Broad use‑of‑proceeds “transition bond”


* Eligibility too loose and backward‑looking: While proceeds are notionally earmarked, the list of eligible projects is very broad and includes minor efficiency upgrades and general maintenance on existing blast furnaces. These measures can be useful but are not transformative.  
* Risk of lock‑in: Channelling a large share of proceeds into incremental efficiency in blast‑furnace assets risks extending their economic life, which is incompatible with most 1.5–2°C decarbonisation pathways for steel that require accelerated phase‑down of such capacity.  
* Weak alignment with transition plan: Only a subset of proceeds (eg the DRI pilot, process electrification) clearly supports a long‑term shift to low‑carbon steelmaking. Investors have limited comfort that the bond is financing the core transition levers rather than marginal, cost‑saving tweaks.


Path B is better than A, but still falls short of a robust, Paris‑aligned transition instrument because it does not sufficiently prioritise or protect truly transformational investments.


Path C – Sustainability‑linked loan with a single 2035 KPI


* Target timing is too distant: A single 2035 emissions‑intensity target provides little discipline in the critical 2020s, when most climate scenarios require steep emission reductions. There is no mechanism to ensure near‑term action.  
* No interim milestones: Without 2025/2028/2030 checkpoints, management can defer hard decisions (such as blast‑furnace retirements) and hope to “catch up later”, leaving investors exposed if the transition stalls.  
* Insufficient financial signal: A one‑off, modest margin step‑up is unlikely to be material relative to the €2 billion capex and overall transition risk. It does not create a strong incentive to stick to a Paris‑aligned pathway.  
* Ambiguous drivers of performance: Because the KPI is defined only at the corporate level, the target could be met via divestments, shifts in product mix or outsourcing emissions‑intensive stages, rather than genuine technological decarbonisation (eg DRI and electrification). That weakens the link between the loan and real‑economy emissions cuts.


Path C embeds a target in form, but not in substance: it is too weak and too delayed to give investors confidence that financed activities will be aligned with a credible steel transition.
