On Thursday 15 June 2023, Zanders hosted a roundtable on ‘Climate Scenario Design & Stress Testing’. In our head office in Utrecht, we welcomed risk managers from several Dutch banks. This article discusses our view on the topic and highlights key insights from the roundtable. 

In recent years, many banks took their first steps in the integration of climate and environmental (C&E) risks into their risk management frameworks. The initial work on climate-related risk modeling often took the form of scenario analysis and stress testing. For example, as part of the Internal Capital Adequacy Assessment Process (ICAAP) or by participating in the 2022 Climate Stress Test by the European Central Bank (ECB). To comply with the ECB’s expectations on C&E risks, banks are actively exploring methodologies and data sources for adequate climate scenario design and stress testing. The ECB requires that banks will meet their expectations on this topic by 31 December 2024. 

Our view

We believe that banks should start early with climate stress testing, but in a manageable and pragmatic way. Banks can then improve their methodologies and extend their scope over time. This allows for a gradual development of knowledge, data and methodologies within all relevant Risk teams. Zanders has identified the following steps in the process of climate scenario design and stress testing: 

• Step 1: Scenario selection 
  A bank has to select appropriate (climate) scenarios based on the bank’s climate risk materiality assessment. Important to consider in this phase is the purpose for which the scenarios will be used, whether the scenarios are in line with scientific pathways, and whether they account for different policy outcomes (like an early or late transition to a sustainable economy). 

• Step 2: Scope and variable definition 
  An appropriate scope must then be selected and appropriate variables defined. For example, banks need to determine which portfolios to take in scope, which time horizons to include, select the granularity of the output, the right level of stress, and which climate- and macro-economic variables to consider. 

• Step 3: Methodology 
  Then, the bank needs to develop methodologies to calculate the impact of the scenarios. There are no one-size-fits-all approaches and often a combination of different qualitative and quantitative methodologies is needed. We recommend that the climate stress test approach be initially simple and to focus on material exposures. 

• Step 4: Results 
  It is important to use the results of the scenario analysis in the relevant risk and business processes. The results can be used for the bank’s risk appetite and strategy. The results can also help to create awareness and understanding among internal stakeholders, and support external disclosures and compliance. 

• Step 5: Stress testing framework 
  Finally, banks should establish minimum standards for climate scenario design and stress testing. This framework should include, amongst others, policies and processes for data collection from different sources, how adequate knowledge and resources are ensured, and how the scenarios are kept up-to-date with the latest market developments. 

Key insights 

Prior to the roundtable, participants filled in a survey related to the progress, scope and challenges on climate risk stress testing. The key insights presented below are based on the results of this survey, together with the outcomes of the discussion thereafter. 

The financial sector has advanced with several aspects around integrating climate risks in risk management over the past year. This was recognized by all participants, as they had all performed some form of climate risk stress testing. The scope of the stress testing, however, was relatively limited in some cases. For example, all participants considered credit risk in their climate risk scenario with many also including market risk. Only a limited number of participants took other risk types into account. 

Furthermore, all participants assessed the short-term impact (up to 3 years) of the climate scenarios, whereas only around 40% and 10% assessed the impact on the medium term (3 to 10 years) and long term (>10 years), respectively. This is probably related to the fact that all participants used climate scenarios in their ICAAP, which typically covers a three-year horizon. The second most mentioned use for the climate scenarios, after the ICAAP, was the risk identification & materiality analysis. A smaller percentage of participants also used the climate scenarios for business strategy setting, ILAAP and portfolio management. 

The two topics that were unanimously mentioned as the main challenges in climate risk stress testing are data selection and gathering, and the quantification of climate risks into financial impacts, as shown in the graph below: 

• Insight 1: Assessing impact of climate risk beyond the short-term very much increases the complexity and uncertainty of the exercise 
  The participants indicated that climate stress testing beyond the short-term horizon (beyond 3 to 5 years) is very difficult. Beyond that horizon, the complexity of the (climate) scenarios increases materially due to uncertainties of clients’ transition plans, the bank’s own transition plan and climate strategy (e.g., related to pricing and client acceptance policies), and climate policies and actions from governments and regulators. Taking the transition plans of clients into account on a granular level is especially difficult when there is a large number of counterparties. There are no clear solutions to this. Some ideas that take longer-term effects into account were floated, such as adjusting the current valuation of various assets by translating future climate impact on assets into a net present value of impact or by taking climate impacts into account in the long-term macro-economic scenarios of IFRS9 models. 

• Insight 2: Whether to use a top-down or bottom-up approach depends on the circumstances 
  It was discussed whether a bottom-up stress test for climate scenarios is preferable to a top-down stress test. The consensus was that this depends on the circumstances, for example: 
  • Physical risks are asset- and location-specific; one street may flood but not the next. So, in that case a bottom-up assessment may be necessary for a more granular approach. On the other hand, for transition risks, less granularity might be sufficient as transition policies are defined on national or even supranational level, and trends and developments often materialize on sector-level. In those cases, a top-down type of analysis could be sufficient. 
  • If the climate stress test is used to get a general overview of where risks are concentrated, a top-down analysis may be appropriate. However, if it is used to steer clients, a more granular, bottom-up approach may be needed. 
  • A bottom-up approach could also be more suitable for longer-term scenarios as it allows to include counterparty-specific transition plans. For more short-term scenarios, a sector average may be sufficient, considering that there will be less transition during this period.

• Insight 3: Translating the results of climate risk stress testing into concrete actions is challenging 
  The results of the stress test can be used to further integrate climate risk into risk management processes such as materiality assessment, risk appetite, pricing, and client acceptance. Most participants, however, were still hesitant to link any binding actions to the results, such as setting risk limits (e.g., limiting exposures to a certain sector), adjusting client acceptance, or amending pricing policies. However, the ECB does require banks to consider climate impacts in these processes. The most mentioned uses of the climate risk stress testing results were risk identification & materiality assessments and risk monitoring.  

Conclusion 

Most banks have taken first steps in relation to climate scenario design and stress testing. However, many challenges still remain, for example around data selection and quantification methodologies. Efforts by banks, regulators and the market in general are required to overcome these challenges. 

Zanders has already supported several banks with climate scenario design and stress testing. This includes the creation of a climate scenario design framework, the definition of climate scenarios, and by quantifying climate risk impacts for the ICAAP. Next to that, we have performed research on modeling approaches that can be used to quantify the impact of transition and physical risks. If you are interested to know how we can help your organization with this, please reach out to Marije Wiersma.

More simply put, the EBA was asked to investigate whether the current prudential framework properly captures environmental and social risks. In response, the EBA published a Discussion Paper (DP) [1] in May 2022 to collect input from stakeholders such as academia and banking professionals.

These risks stem from the transition towards a low carbon economy and from the physical risks of damages due to extreme weather events. To address climate-related financial risks within the banking sector, the Basel Committee on Banking Supervision (BCBS) established a high-level Task Force on Climate-related Financial Risks in 2020. It contributes to the BCBS’s mandate to strengthen the regulation, supervision and practices of banks worldwide with the purpose of enhancing financial stability.

Both the BCBS’s Core principles for effective banking supervision¹ and the Supervisory Review and Evaluation Process (SREP) within the existing Basel Framework are considered sufficiently broad and flexible to accommodate additional supervisory responses to climate-related financial risks. It was felt, however, that supervisors and banks could benefit from the publication of the Principles for the effective management and supervision of climate-related financial risks². Through this publication, the BCBS seeks to promote a principles-based approach to improving risk management and supervisory practices regarding climate-related financial risks. The document contains principles directed to banks and principles directed to supervisory authorities. In this article, we present an overview of the principles directed to banks.

The BCBS published a draft of their Principles in November 2021. During the consultation phase, which lasted until February 2022, banks and supervisors could provide feedback. The BCBS incorporated their feedback in the final version of the Principles that were published in June 2022.

Principles for the management of climate-related financial risks

In total, twelve bank-focused principles are presented and grouped in eight categories. Each of the eight categories is briefly discussed below:

Corporate governance – Principles 1 to 3

The principles related to corporate governance state that banks first need to understand and assess the potential impact of climate risks on all fields they operate in. Subsequently, appropriate policies, procedures and controls need to be implemented to ensure effective management of the identified risks. Furthermore, roles and responsibilities need to be clearly defined and assigned throughout the bank. To successfully manage climate-related risks, banks should ensure an adequate understanding of climate-related financial risks and as well as adequate resources and skills at all relevant functions and business units within the bank. Finally, the board and senior management should ensure that all climate-related strategies are consistent with the bank’s stated goals and objectives.

Internal control framework – Principle 4

The fourth principle within the internal control framework subcategory requires banks to include clear definitions and assignment of climate-related responsibilities and reporting lines across all three lines of defense. Further requirements are then presented for each line of defense.

Capital and liquidity adequacy – Principle 5

After the identification and quantification of the climate-related financial risks, these risks need to be incorporated into banks’ Internal Capital (and Liquidity) Adequacy Assessment Process (ICLAAP). Banks should provide insights in which climate-related financial risks affect their capital and liquidity position. In addition, physical and transition risks relevant to a bank’s business model assessed as material over relevant time horizons, should be incorporated into their stress testing programs in order to evaluate the bank’s financial position under severe but plausible scenarios. Furthermore, the described incorporation in the ICLAAP to handle such financial risks, should be done iteratively and progressively, as the methodologies and data used to analyze these risks continue to mature over time.

Risk management process – Principle 6

The sixth principle connects to the previous one, as it states that a bank needs to identify, monitor and manage all climate-related financial risks that could materially impair their financial condition, including their capital resources and liquidity positions. The bank’s risk management framework should be comprehensive with respect to the (material) climate-related financial risks they are exposed to. Clear definitions and thresholds should be set for materiality. These need to be monitored closely and adjusted, if necessary, as climate-related risks are evolving.

Management monitoring and reporting – Principle 7

After ensuring that the risk framework is comprehensive, banks need to implement the monitoring and reporting of climate-related financial risks in a timely manner to facilitate effective decision-making. To achieve such reporting, a good data infrastructure should be in place at the bank. This allows it to identify, collect, cleanse, and centralize the data necessary to assess material climate-related financial risks. Furthermore, banks should actively collect additional data from clients and counterparties in order to develop a better understanding of their client’s transition strategies and risk profiles.

Management of credit, market, liquidity, operational risk – Principles 8 to 11

Banks should understand the impact of climate-related risk drivers on their credit risk profiles, market positions, liquidity risk profiles and operational risks. Clearly articulated credit policies and processes to identify, measure, evaluate, monitor, report and control or mitigate the impacts of material climate-related risk drivers on banks’ credit risk exposures should be in place. From a market risk perspective, banks should consider the potential losses in their portfolios due to climate-related risks. On the business operation and strategy side of banking activities, the impact of climate-related risks also plays a large role. For example, physical risks have to be taken into account when drafting business continuity plans. After understanding the different risks and their impacts, a range of risk mitigation options to control or mitigate climate-related financial risks need to be considered.

Scenario analysis – Principle 12

The final principle states that banks need to use scenario analysis to assess the resilience of their business models and strategies to a range of plausible climate-related pathways, and to determine the impact of climate-related risk drivers on their overall risk profile. Scenario analysis should reflect the overall relevant climate-related financial risks for banks, including both physical and transition risks. This analysis should be performed for different time horizons, both short- and long-term, and should be highly dynamic.

Changes to the BCBS risk framework draft and related publications

The final Principles have not changed much compared to the November 2021 consultation document. The most important changes are that the first principle, concerning corporate governance of banks, and the fifth principle, concerning capital and liquidity adequacy, have been extended. The corporate governance principle, for example, now also includes that banks should ensure that their internal strategies and risk appetite statements are consistent with any publicly communicated climate-related strategies and commitments. The capital and liquidity adequacy principle now includes a section requiring banks to incorporate material climate-related financial risks in their stress testing programs.

These twelve bank-focused principles, providing banks guidance on effective risk management of climate-related financial risks, can also be linked to the initiatives of other regulators such as the ECB. In November 2020, for example, the ECB provided a guide that describes how it expects institutions to consider climate-related and environmental risks, when formulating and implementing their business strategy, governance and risk management frameworks (the ECB expectations). These ECB expectations are in line with the BCBS Principles (and often more elaborate).

Zanders has gained relevant experience in implementing the ECB expectations at several Dutch banks. This experience ranges from risk identification and materiality assessments to the quantification of climate-related risks, ESG data frameworks, model validations, and scenario analysis. Please reach out to us if your bank is seeking support in implementing the BCBS Principles.

But to seize the opportunities ESG must become an integrated part of a bank’s strategy, risk management and disclosure regimes. High-quality data is instrumental to identify and measure ESG risks, but it can be lacking. FIs need to improve their internal data and use of external private and public vendors like Moody’s or the IMF, while developing a framework that plugs any data gaps.

The lack of appropriate ESG data is considered one of the main challenges for many FIs, but proxies, such as using a building’s energy rating to work out its carbon emissions, can be used.

FIs need climate change-related data that isn’t always available if you don’t know where to look. This article will give you an overview of the most relevant data vendors and provide suggestions on how to treat missing data gaps in order to get a comprehensive ESG framework for the green future where carbon measurement, assessment, reporting and trading will be vital

The data challenge

In May 2021, the Network for Greening the Financial System (NGFS) published a ‘Progress report on bridging data gaps’. In this report, the NGFS writes that meeting climate-related data needs is a challenge that can be described along the following three dimensions:

• data availability,
• reliability,
• & comparability.

A further breakdown of the challenges related to these dimensions can be found in Figure 1.

Figure 1: The dimensions of the climate-related data challenge.
Source: Graphic adapted by Zanders from a NGFS report entitled: ‘Progress report on bridging data gaps’ (2021).

Key financial metrics

The NGFS writes that a mix of policy interventions is necessary to ensure climate-related data is based on three building blocks:

1. Common and consistent global disclosure standards.
2. A minimally accepted global taxonomy.
3. Consistent metrics, labels, and methodological standards.

EU Taxonomy, CSRD & EBA’s 3 ESG risk disclosure standards

Several initiatives have started to ignite these needed policy interventions. For example, the EU Taxonomy, introduced by the European Commission (EC), is a classification system for environmentally sustainable activities. In addition, the recently approved Corporate Sustainability Reporting Directive (CSRD) provides ESG reporting rules for large listed and non-listed companies in the EU, including several FIs. The aim of the CSRD is to prevent greenwashing and to provide the basis for global sustainability reporting standards. Another example of a disclosure standard is the binding standards on Pillar 3 disclosures on ESG risks developed by the European Banking Authority (EBA).

Even though policy, law and regulation makers have a big part to play in the data challenge, there are also steps that individual institutions could and should take to improve their own ESG data gaps. Regulatory bodies such as the EBA and the European Central Bank (ECB) have shared their expectations and recommendations on the management of ESG data with FIs.

To illustrate, the EBA recommends FIs “[identify] the gaps they are facing in terms of data and methodologies and take remedial action” and the ECB expects institutions to “assess their data needs in order to inform their strategy-setting and risk management, to identify the gaps compared with current data and to devise a plan to overcome these gaps and tackle any insufficiencies”

Collecting data

Collecting ESG data is a challenging exercise. A distinction can be made between collecting data for large market cap companies, and small cap companies and retail clients. Although large cap companies tend to be more transparent, the data often is dispersed over multiple reports – for example, corporate sustainability reports, annual reports, emissions disclosures, company websites, and so on.

For small cap companies and retail clients, the data is more difficult to acquire. Data that is not publicly available could be gathered bilaterally from clients. For example, one European bank has developed an annual client questionnaire to collect data from its clients.

Gathering data from various reports or bilaterally from clients might not always be the best option, however, because it is time consuming or because the data is not available, reliable, or comparable. Two alternatives are:

1. Use tools to collect the data. For example, using open-source tooling from the Two Degrees Investing Initiative (2DII) to calculate Paris Agreement Capital Transition Assessment (PACTA) portfolio alignment.
2. Collect data from other external data sources, such as S&P Global.

This could be forward-looking external data on macro-economic expectations, international climate scenarios, financial market data or sectoral climate developments. Below we discuss some sources for external ESG and climate change-related data.

External data

Some of Zanders’ clients resort to vendor solutions for acquiring their ESG data. The most commonly observed solutions, in random order, are:

All the solutions above provide an aid to determine if climate related performance data is lacking, or can assist in reporting comparable and reliable data. They all apply a similar process of collecting the data and determining ESG scores, which is illustrated in Figure 2.

Figure 2: Data collection process for ESG data solutions (Source: Zanders).

Additionally, public and non-commercial data and solution providers are available, such as:

Missing data

Given the data challenges, it is nearly impossible to create a complete data set. Until that is possible, there are several (temporary) methods to deal with missing data:

• Find a comparable loan, asset, or company for which the required data is available.
• Distribute sector data based on market share of individual companies. For example, assign 10% of the estimated emission of sector X to company Y based on its market share of 10%.
• Find a proxy, comparable or second-best metric. For example, by taking the energy label as a proxy for CO2 emission related to properties, or by excluding scope 3 emissions and focusing on scope 1 and 2 emissions.
• Change the granularity level. For example, by gathering data on sector level rather than on individual positions.
• Fill in the gaps with statistical or machine learning techniques.

Conclusion

The increased attention to integrating ESG risks into existing risk frameworks has led to a need for FIs to collect and disclose meaningful data on ESG factors. However, there is still a lack of data availability, reliability, and comparability.

Several regulatory and political efforts are ongoing to tackle this data challenge, such as the EU taxonomy. More policy interventions, however, are required. Examples are additional mandatory disclosure requirements, an audit and validation framework for ESG data, and social and governance taxonomies that classify economic activities that contribute to social and governance goals.

In the meantime, FIs have to find ways to produce meaningful insights and comply with regulatory requirements related to ESG risks. Zanders has experienced that there is no one-size-fits-all solution for defining, selecting, implementing, and disclosing relevant data and metrics. It is dependent on the composition of the asset and loan portfolio, the use of the data, and the data that is (already) available. Regardless of how the lack of data is solved, it is important that FIs are transparent about their choices and methodologies, and that the related metrics and scorings are explainable and intuitive.

The Working Group II contribution to the IPCC’s Sixth Assessment Report states that “climate change is a grave and mounting threat to our wellbeing and a healthy planet”. It is a formidable, global challenge to transition to a sustainable economy before time is running out. Banks have an important role to play in this transition. By stepping up to this role now, banks will be better prepared for the future, and reap the benefits along the way.

In the Paris Agreement (or COP21), adopted in December 2015, 196 parties agreed to limit global warming to well below 2.0°C, and preferably to no more than 1.5°C. To prevent irreversible impacts to our climate, the IPCC stresses that the increase in global temperature (relative to the pre-industrial era) needs to remain below 1.5°C. To achieve this target, a rapid and unprecedented decrease in the emission of greenhouse gasses (GHG) is required. With CO2 emissions still on the rise, as depicted in Figure 1, the challenge at hand has increased considerably in the past decade.

Figure 1 – Annual CO2 emissions from fossil fuels.

To further illustrate this, Figure 2 depicts for several starting years a possible pathway in CO2 reductions to ensure global warming does not exceed 2.0°C. Even under the assumption that CO2 emissions have already peaked, it becomes clear that the required speed of CO2 reductions is rapidly increasing with every year of inaction. We are a long way from limiting global warming to 2.0°C. This even holds under the assumption that all countries’ pledges to reduce GHG emissions will be achieved, as can be observed in Figure 3.

To quote the IPCC Working Group II co-chair Hans-Otto Pörtner: “Any further delay in concerted anticipatory global action on adaptation and mitigation will miss a brief and rapidly closing window of opportunity to secure a livable and sustainable future for all.”

The role of banks in the transition – and the opportunities it offers

Historically, banks have been instrumental to the proper functioning of the economy. In their role as financial intermediaries, they bring together savers and borrowers, support investment, and play an important role in facilitating payments and transactions. Now, banks have the opportunity to become instrumental to the proper functioning of the planet. By allocating their available capital to ‘green’ loans and investments at the expense of their ‘brown’ counterparts, banks can play a pivotal role in the transition to a sustainable economy. Banks are in the extraordinary position to make a fundamentally positive contribution to society. And even better, it comes with new opportunities.

The transition to a sustainable economy requires huge investments. It ranges from investments in climate change adaption to investments in GHG emission reductions: this covers for example investments in flood risk warning systems and financing a radical change in our energy mix from fossil-fuel based sources (like coal and natural gas) to clean energy sources (like solar and wind power). According to the Net Zero by 2050 Report from the International Energy Agency (IEA)², the annual investments in the energy sector alone will increase from the current USD 2.3 trillion to USD 5.0 trillion by 2030. Hence, across sectors, the increase in annual investments could easily be USD 3.0 to 4.0 trillion. As much as 70% of this investment may need to be financed by the private sector (including banks and other financial institutions)³. To put this in perspective, the total outstanding credit to non-financial corporates currently stands at USD 86.3 trillion⁴. Assuming an average loan maturity of 5 years, this would translate to a 12-16% increase in loans and investments by banks on a global level. Hence, the transition to a sustainable economy will open up a large market for banks through direct investments and financing provided to corporates and households.

The transition to a sustainable economy is also triggering product development. The Climate Bonds Initiative (CBI) for example reports that the combined issuance of Environmental, Social, and Governance (ESG) bonds, sustainability-linked bonds and transition debt reached almost USD 500 billion in 2021H1, representing a 59% year-on-year growth rate. Other initiatives include the introduction of ‘green’ exchange-traded funds (ETFs) and sustainability-linked derivatives. The latter first appeared in 2019 and they provide an incentive for companies to achieve sustainable performance targets. If targets are met, a company is for example eligible for a more attractive interest coupon. Again, this is creating an interesting market for banks.

By embracing the transition, with all the opportunities that it offers, banks are also bracing themselves for the future. Banks that adopt climate change-resilient business models and integrate climate risk management into their risk frameworks will be much better positioned than banks that do not. They will be less exposed to climate-related risks, ranging from physical and transition risks to risks stemming from a reputational perspective or litigation, also justifying lower capital requirements. The early adaptors of today will be the leaders of tomorrow.

A roadmap supporting the transition

How should a bank approach this transition? As depicted in Figure 4, we identify four important steps: target setting, measurement and reporting, strategy and risk framework, and engaging with clients.

Figure 4 – The roadmap supporting the transition to a sustainable economy.

Target setting

The starting point for each transition is to set GHG emission targets in alignment with emission pathways that have been established by climate science. One important initiative that can support banks in setting these targets is the Science Based Targets initiative (SBTi). This organization supports companies to set targets in line with the goals of the Paris Agreement. Unlike many other companies, the majority of a bank’s GHG emissions are outside their direct control. They can influence, however, their so-called financed emissions, which are the GHG emissions coming from their lending and investment portfolios. The SBTi has developed a framework for banks that reflects this. It encourages banks to use the Absolute Contraction approach that requires a 2.5% (for a well-below 2.0°C target) or 4.2% (for a 1.5°C target) annual reduction in GHG emissions. A clear emission pathway guides banks in the subsequent steps of the transition process.

Measurement and reporting

With targets in place, the next important step for a bank is to determine their level of GHG emissions: both for scope 1 and 2 (the GHG emissions they control) and for scope 3 (the financed emissions). Important initiatives for the quantification of the financed emissions are the Paris Agreement Capital Transition Assessment (PACTA) and the Platform Carbon Accounting Financials (PCAF). PCAF is a Dutch initiative to deliver a global, standardized GHG accounting and reporting approach for financial institutions (building on the GHG Protocol). PACTA enables banks to measure the alignment of financial portfolios with climate scenarios.

By keeping track of the level of GHG emissions on an annual basis, banks can assess whether they are following their selected emission pathway. Reporting, in line with the recommendations of the Task Force on Climate-Related Financial Disclosures (TCFD), will contribute to a greater understanding of climate risks with their investors and other stakeholders.

Strategy and risk framework

Setting targets and measuring the current level of GHG emissions are necessary but not sufficient conditions to achieve a successful transition. Climate change risk needs to be fully integrated into a bank’s strategy and its risk framework. To assess the climate change-resilience of a bank’s strategy, a logical first step is to understand which climate change risks are material to the organization (e.g., by composing a materiality matrix). Subsequently, studying the transmission channels of these risks using scenario analysis and/or stress testing creates an understanding of what parts of the business model and lending portfolio are most exposed. This could lead to general changes in a bank’s positioning, but these risks should also be factored into the bank’s existing risk framework. Examples are the loan origination process, capital calculations, and risk reporting.

Engaging with clients

A fourth step in the game plan to successfully support the transition is for a bank to actively engage with its clients. A dialogue is required to align the bank’s GHG emission targets with those of its clients. This extends to discussing changes in the operations and/or business model of a client to align with a sustainable economy. This also may include timely announcing that certain economic activities will no longer be financed, and by financing client’s initiatives to mitigate or adapt to climate change: e.g., financing wind turbines for clients with energy- or carbon-intensive production processes (like cement or aluminium) or financing the move of production locations to less flood-prone areas.

Conclusion

Banks are uniquely positioned to play a pivotal role in the transition to a sustainable economy. The transition is already providing a wide range of opportunities for banks, from large financing needs to the introduction of green bonds and sustainability-linked derivatives. At the same time, it is of paramount importance for banks to adopt a climate change-resilient strategy and to integrate climate change risk into their risk frameworks. With our extensive track record in financial and non-financial risk management at financial institutions, Zanders stands ready to support you with this ambitious, yet rewarding challenge.

ESG risk management and Zanders

Zanders is currently supporting several clients with the identification, measurement, and management of ESG risks. For a start, we are supporting a large Dutch bank with the identification of ESG risk factors that have a material impact on the credit risk profile of its portfolio of corporate loans. The material risk factors are then integrated in the bank’s existing credit risk framework to ensure a proper management of this new risk type.

We are supporting other banking clients with the quantification of climate change risk. In one case, we are determining climate change risk-adjusted Probabilities of Default (PDs). Using expected future emissions and carbon prices based on the climate change scenarios of the Network for Greening the Financial System (NGFS), company specific shocks based on carbon prices and country specific shocks on GDP level are determined. These shocked levels are then used to determine the impact on the forecasted PDs. In another case, we are investigating the potential impact of floods and droughts on the collateral value of a portfolio of residential mortgage loans.

We also gained experience with the data challenges involved in the typical ESG project: e.g., we are supporting an asset manager with integrating and harmonizing ESG data from a range of vendors, which is underlying their internally developed ESG scores. We also support them with embedding these scores in the investment process.

With our extensive track record in financial and non-financial risk management at financial institutions in general, and our more recent ESG experience, Zanders stands ready to support you with the ambitious, yet rewarding challenge to adopt a climate change-resilient strategy and to integrate climate change risk in your existing risk frameworks.

Next to sustainable funding instruments, including both green and social, we also see that these KPI’s can be used for other financial instruments, such as ESG (Environmental, Social, Governance) derivatives. These derivatives are a useful tool to further drive the corporate sustainability strategy or support meeting environmental targets.

Climate change risks are relatively newly identified risks that insurers are facing. These risks can negatively impact both assets and liabilities of insurers. Already in 2018, the European Commission requested the European Insurance and Occupational Pensions Authority (EIOPA) to investigate how climate change risk could be integrated into the Solvency II Framework.

After various previous publications¹ of (draft) opinions, the investigation resulted in EIOPA’s opinion to include climate change risk scenarios in Own Risk and Solvency Assessment (ORSA)². It basically points out that forward-looking management of climate change risks is essential, and that EIOPA expects insurers to integrate climate change risk scenarios in their ORSA. EIOPA indicates it will start monitoring the application of this opinion two years after publication, i.e. as of April 2023. However, some National Competent Authorities already require insurers to take climate change risks into account.³

So, what will be expected of insurers?

In general terms, insurers are expected to:

• Integrate climate change risks in their system of governance, risk management system and ORSA
• Assess climate change risk in ORSA in the short and long term
• Disclose climate-related information

But what does this mean in practice? We will further explained this per topic.

Integrating climate change risks

The integration requirement ensures that climate change risk becomes an integral part of the day-to-day business and the risk management framework. The EIOPA opinion does not provide much detail on what this entails. Draft amendments to the delegated regulation, published by the European Commission, provide more insight into what insurers can expect.

The draft amendments relate especially to the implementing measures of the system of governance laid out in the Solvency II Directive. This means that responsibilities regarding climate change risk need to be clearly allocated towards the key functions within the organization, and appropriately segregated to ensure an effective system of governance.

This means climate change risk should be included in the following functions/processes:

• Risk Management
  For all the relevant risk management areas – covering both the asset and the liability side of the balance sheet, and including liquidity, concentration and operational risk – climate change risks need to be identified, measured, monitored, managed and reported on.
• ORSA
  The ORSA is a mandatory part of the required system of governance for insurers and will therefore also have to take climate risks into account. In order to properly assess the potential impact of climate change risks and the resilience of the insurers’ business model, these climate change risks need to be analyzed over a longer horizon. EIOPA has therefore advised to include climate change scenarios in the ORSA. This will be discussed in more detail in the next section of this article.
• Internal Control and Internal Audit
  Changes in the system of governance, risk management and ORSA to incorporate climate change risk also requires extension of the internal control system and the scope of internal audit.
• Actuarial Function
  The actuarial function will be responsible for the appropriateness of assumptions, methodologies and models used to assess the impact of climate change risks in underwriting. Especially in the context of ORSA and the assessment of the influence climate risk has on future reserving and capital needs. In addition, the actuarial function will be responsible for the sufficiency and quality of the data used within these calculations.

Consequently, written policies regarding risk management, internal control, internal audit, outsourcing (where relevant) and contingency plans need to be updated to include everything outlined above with regards to climate change risk.

Assess climate change risk in ORSA in the short and long term

Insurers will be required to assess climate change risk in ORSA by analyzing at least two climate scenarios. For the implementation we suggest a four-step approach, largely based on the guidance provided by EIOPA.

Step 1 – Risk identification

EIOPA expects insurers to take a broad view of climate change risks and include all risks stemming from trends or events caused by climate change. EIOPA provides a list of these risks, which distinguishes between:

• Transition risks
  These are defined as follows: ‘Risks that arise from the transition to a low-carbon and climate-resilient economy’. This includes the following aspects: Policy, Legal, Technology, Market sentiment and Reputational risks.
• Physical risks
  These are defined as: ‘risks that arise from the physical effects of climate change’ and are subdivided in acute and chronic physical risks.

Materialization of these risks for insurers will translate into impact on traditional risk categories, such as underwriting risk, market risk, credit and counterparty risk, operational risk, reputational risk and strategic risk. To help insurers get started with the implementation of climate change risks in ORSA, EIOPA has provided examples of a mapping in the annex of their opinion.

Step 2 – Materiality assessment

Insurers will be required to include all material climate change risks in ORSA. Under Solvency II, risks are considered material if ignoring the risk could lead to different decision making. This means that insurers are required to assess the materiality of each risk to determine whether these need to be included. If an insurer concludes that a certain climate change risk is immaterial, the insurer must be able to explain how that conclusion was reached.

The materiality assessment should be a combination of a qualitative and a quantitative analysis. The qualitative analysis is to provide insight in the relevance of the climate change risk drivers and the way they impact the traditional prudential risks (underwriting risk, market risk etc.). The quantitative analysis will be used to determine the extent to which assets and liabilities are exposed to transition and physical risks.

Step 3 – Defining scenarios

The inclusion of the forward-looking, risk-based approach to ORSA requires insurers to define a set of climate change risk scenarios. EIOPA expects insurers to assess material climate change risks utilizing ‘a sufficiently wide range of stress tests or scenario analysis, including the material short- and long-term risks associated with climate change’. The goal of these scenarios is to assess the resilience and robustness of the insurer’s business strategies, including the impact of risk mitigating measures.

EIOPA states that insurers may develop their own climate scenarios or build on existing ones and provides a number of sources of publicly available scenarios containing pathways for physical and transition risks. The decision for internal scenario development versus building on publicly available may depend on many factors like expected materiality or company size. For example, the underwriting risk for a life insurer is probably less exposed to transition risk than the underwriting risk for a non-life insurer, and a smaller insurer may not have sufficient expertise and resources.

The scenarios must project a multitude of external factors to properly capture the effects of climate change risks. Factors such as demographics (e.g. in case of natural disasters), economic development (e.g. as a result of technological breakthrough) and government policies to reduce carbon emissions, just to name a few. The climate change scenario set should contain at least two long-term climate scenarios:

• Global temperature increase remains below 2◦C, preferably no more than 1.5◦C, in line with Paris Agreement;
• Global temperature increase exceeds 2◦C.

In addition, a reference scenario is needed to be able to determine the impact of the stress scenarios.

The assessment is to be performed for several time horizons. Given the nature of climate change risks, horizons need to be in the order of decades. EIOPA provides examples for length of time horizons, ranging from instantaneous (‘current climate change’) to projected views of climate change for the next 80 years (‘long-term climate change’).

Step 4 – Climate change risk modeling

Modeling climate change risks in ORSA introduces two challenges:

• Assessment of transition and physical risk impacts
  Materialization of transition and physical risks will have to be translated to impact on assets and liabilities. In a discussion paper, EIOPA provides examples of different methodologies for the assessment of transition impacts on assets, that have already been developed by academics, research institutes and regulators⁴. In general, these methodologies use carbon-sensitivities of financial instruments to assess the impact of climate change risk scenarios.
  The basis for the determination of physical risks is the change in temperature over time. This change needs to be translated into impact on frequency and severity of acute natural disasters (e.g. storms, floods, fires or heatwaves) and chronic effects (e.g. rising sea levels, reduced water availability, biodiversity loss and changes in land and soil productivity). The next step is to translate these effects into impact on assets and liabilities. The translation into financial impact on companies in which insurers invest can especially be challenging. Larger companies often have a greater diversity of activities and are more spread out geographically. In addition, companies will not only be hindered by the materialization of physical risks in their own activities, but their supply chain can also be affected. However, some scoring models already exist in which companies are ranked based on their sensitivity to physical risks.⁵
• Long-term multi-period modelling
  Incorporation of the climate change risk scenarios in ORSA aims to assess the viability of current business models and strategies and the adequacy of the insurers’ solvency. For longer horizons, insurers may use a lower precision for balance sheet projections and conduct assessment at a lower frequency than short-term risk assessments.
  The lower precision allows for simplifications as long as the long-term character of the climate change scenarios is preserved. Simplifications may include projecting simple ratios instead of full balance sheets, or assessment of climate change impact on assets and technical provisions in isolation. However, projection of the full balance sheet ensures internal consistency and may provide much more information, especially when assessing the impact of potential management actions to mitigate the impact of climate change risks.

Disclose climate-related information

Insurers are expected to provide explanation on the short- and long-term climate change risk analysis in the ORSA report. This should include:

• An overview of all material risks, how materiality is assessed and an explanation for each risk that is considered immaterial.
• The methods and assumptions used by the insurer in both the materiality assessment of the climate change risks and in ORSA.
• The outcomes and conclusions of the scenario analysis, both quantitative and qualitative.

In addition, climate change risk related disclosures should be consistent with the Non-Financial Reporting Directive (NFRD).⁶
