2. Introduction
Globally, climate and nature risks are rated as some of the most impactful risks2 in the short, medium and long term. The impacts of climate change and nature loss continue to grow each year and extend to the whole financial services sector. This introduces climate and nature risks and opportunities. Financial services sector firms are being increasingly expected to effectively manage climate and nature risks and take advantage of related opportunities. The following diagram3 illustrates how the risks and opportunities of climate change and nature loss can financially impact a business.

2.1 Applicability
This guidance note aims to provide support to enable all firms to identify and manage climate and nature risks and opportunities within their business strategies and models. Specifically, this guidance note applies to firms regulated under the following acts:
 The Financial Services Act 2008.
 The Insurance Act 2008.
 The Collective Investment Schemes Act 2008.
This note in its entirety will not be relevant for every firm. Certain sections will only be relevant for certain types of firm. Relevance may vary depending upon the firm’s sector, size, complexity, business mix and, critically, the materiality of risks identified. Firms should give consideration to whether they are subject to material climate and nature risks and update their risk management processes accordingly. Subject to meeting the requirements of the relevant regulations and guidance notes, firms have the flexibility to configure their approach to climate and nature risks in a manner best suited to achieving their business objectives.
2.2 Risks
The Authority’s regulatory objectives include ensuring that consumers are protected, and that confidence is maintained in the financial services sector. As such, the Authority seeks to ensure that firms effectively and prudently identify and manage climate and nature risks through good governance and risk management. The Authority’s existing risk management and governance requirements contained within the relevant legislation and guidance apply equally to climate and nature risks as to other traditional risks. Hence, the Authority anticipates that climate and nature risks can be managed within a firm’s existing risk management frameworks.
2.2.1 Specific considerations when managing climate and nature risks
Whilst the Authority considers that climate and nature risks can be managed within a firm’s existing risk management frameworks, it acknowledges that climate and nature risks have different characteristics than other financial risks. The time horizon and pace of emergence of climate and nature risks are highly uncertain and dependent on a range of factors, including the speed and nature of any political actions and developments in technology. Whilst it is uncertain how and when climate and nature risk events will materialise, there is a high degree of certainty that some financial risks will materialise because of climate change and nature loss. No new requirements imposed Proportionality should be applied

Climate change is a well-developed and understood field, whilst the impact of nature loss and its interaction with climate change is a developing area. Nature loss and climate change interact and exacerbate each other leading to greater overall impacts on the financial services sector and wider economy. Hence, the impact of nature loss risks should not be considered in isolation.4 Some degree of internal capacity building or the hiring of experts may be required when initially considering the impact of climate and nature risks on business strategies and models. Necessity for expertise should be reviewed as part of the governance and risk assessment considerations noted later in this document. Specific risk drivers when managing climate and nature risks include:
 The long-term nature of the risks extends beyond typical planning cycles.  The uncertainty around which risks may materialise and when.  The unprecedented nature of events prevents using historical data to carry out forward looking assessments means current models are unlikely to adequately anticipate future impacts.  The far-reaching impact of events means diversification may no longer provide the same level of benefit.
2.2.2 Double materiality
Double materiality should also be considered. In a climate change context, this means firms should consider both the effect that climate change has on the activities of the business (“outside in”) and the impact of the firm’s activities on the climate (“inside out”). The table below provides examples of the types of considerations different firms may consider depending on their sector. Type of Firm Consideration Trust and Corporate Service Providers (including in their capacity as trustee) Failure to consider the long-term risks posed by climate change and nature loss could be a breach of fiduciary duty to beneficiaries causing litigation risk or a potential loss of clients. Fund Managers and Investment Firms (including financial advisers) Identifying concentrations of climate and nature risks within investment portfolios both mitigates the impact of these risks on investment values, and the reputational risks arising from investments in certain activities. This becomes increasingly important for tailored investment products that respond to the preferences of individual investors. Banks Climate and nature risks have the potential to have an impact on underlying credit risks with counterparties, either through impacts to the value of collateral, or through increased costs for counterparties. See: https://www.oecd.org/content/dam/oecd/en/publications/reports/2023/09/a-supervisory-framework￾for-assessing-nature-related-financial-risks_1fd4b9d6/a8e4991f-en.pdf

Type of Firm Consideration
Banks also can be exposed to reputational risks, and in some cases litigation risks, from the selection of the kinds of businesses that a bank chooses to provide or withhold services from. Insurers and Insurance Managers Climate and nature risks pose particularly complex challenges for insurance underwriting and pricing. This could affect an insurer’s appetite to insure certain risks, resulting in a reduction in insurance penetration and challenges for an insurer’s future business model. Life insurers offering unit-linked products should consider the reputational risk of enabling investment in sectors and industries that cause significant harm to nature and the climate as the world continues to transition. Non-Life insurers who re-price contracts on an annual basis to take account of the impact of evolving climate and nature risks over the medium-to-long term, should consider if this might lead to the risk of insurance coverage becoming unaffordable for the policyholder, as well as the insurer crowding itself out of certain risks.5 See EIOPA: https://www.eiopa.europa.eu/publications/report-non-life-underwriting-and-pricing-light￾climate-change_en

 Physical and transition risks adversely impacting creditworthiness of various counterparties. Strategic risk  Not achieving sustainable strategic growth / profitability metrics.  Ability to continuously offer solutions for customers when physical risks and transition risks increase.  Usual sources of funding may be restricted in the case of strategic failure in a physical event.
2.3 Opportunities
As well as risks, the need to change and adapt to climate and nature risks will also bring opportunities. Good risk management will enable firms to identify and take advantage of these opportunities so they can be factored into business strategies and models. The Authority is committed to supporting Finance Isle of Man’s Sustainable Finance Initiative, which is designed to bolster the Island’s position as a leading international financial centre by directing capital and finance flows toward climate-related, socially positive and nature-based sustainable solutions. The Sustainable Finance Roadmap6 is a strategic document which outlines areas of significant opportunity for financial services businesses in the Isle of Man to develop new product and service lines to meet rapidly increasing global demand for sustainable investments. The Authority is responsible for Pillar 1, the enabling environment. Firms will have the option to avail of the opportunities that the roadmap and adaption will create. This could include new sustainable finance products and innovation in financing and insurance. For example, captive insurers and insurance special purpose vehicles can play a significant role in enabling firms to close their natural catastrophe protection gap7 by providing innovative and cost-effective solutions. The Authority continues to support innovation in this space with its flexible Class 12 (Captive) and Class 13 (ISPV) authorisations. 6 Finance Isle of Man Launches a Sustainable Finance Roadmap The protection gap is the difference between the level of insurance needed to cover catastrophe risk and the amount which is currently available and affordable.  Improve reputation  Increase market share  Market differentiation  Attract top talent  Improve employee retention Funds and investments:  Sustainable investment funds  Green / Blue bonds  Sustainable investment products Insurance:  Sustainable insurance products  Sustainability linked insurance  Natural catastrophe gap insurance  Microinsurance / Parametric insurance  Carbon offset insurance  Environmental liability insurance Banks:  Green loans  Energy efficient mortgages CSPs:  Green/sustainable trusts OPPORTUNITIES

Additionally, trust, fund or investment products could be created to give investors access to investment portfolios that incorporate sustainability considerations. A range of different approaches may be adopted to better meet the needs of sustainability conscious investors. There are also cross-sector opportunities, including green bonds being issued to enable capital raising and investment for projects with environmental benefits, such as green lending or mortgages.
3. Governance
The responsibility for the sound and prudent management of a firm rests with the Board, hence the Authority considers it prudent for boards to seek, understand and regularly assess climate and nature risks, in the near and far term. Boards should require sufficient insight to be able to strategically respond to climate and nature risks, as such they should collectively possess the necessary competence and capacity to assess long-term risks and opportunities related to climate change and nature loss. Boards should be able to evidence their ongoing oversight of their climate and nature risks. This oversight should include (where applicable):
 Ensuring an appropriate understanding of, and opportunity to discuss climate and nature risks at board and sub-committee levels. This should include appropriate training for board members.  Setting clear senior management roles and responsibilities in relation to the management of climate and nature risks.  Ensuring that, where climate and nature risks are determined to be material, the risk management framework incorporates these risks, and in particular sets appetites and tolerances in relation to the risk.  Reviewing material risks and opportunities on a regular basis, and horizon scanning for new ones.  Considering both a short-term view and a long-term view of the risks and opportunities.  Reviewing relevant metrics, as determined by the Board, to enable them to measure risk indicators and performance against targets. Senior management should typically be responsible for:
 Applying the risk management framework to assess and manage climate and nature risk exposures on an ongoing basis, including developing and implementing appropriate policies.  Regularly reviewing the effectiveness of the framework, policies, tools, metrics and targets, and making appropriate revisions, reporting to the Board as applicable.  Providing recommendations to the Board on objectives, plans, strategic options and policies as they relate to material climate and nature risks. This may include the establishment and use of relevant tools, models, and metrics and targets to monitor

Isle of Man Financial Services Authority
Version 1.0 Page 12 of 18
First issued 10 July 2025 exposures to climate risks to enable the Board to make informed decisions in a timely manner.  Ensuring that adequate resources, skills and expertise are allocated to the management of climate and nature risks, including thorough training and capacity building amongst relevant staff, reporting to the Board as applicable. The allocation of responsibility for identifying and managing climate change risk to the relevant functions should reflect the firm’s structure, risk profile, strategy, and risk appetite. These allocations should then be included in the relevant internal control and risk management frameworks.
4. Risk Management
4.1 Overview
Boards are responsible for firms’ risk management frameworks. Senior management should monitor and manage all material risks consistent with the strategic objectives, risk appetite and policies approved by the Board. Material climate and nature risks should be considered within existing risk management frameworks, including the risk appetite, risk assessments, risk management strategy and business plan. Where a firm belongs to a group, due consideration should be given to how group policies appropriately reflect the firm’s own risk exposures, tolerances and requirements. Firms should also ensure that there is the necessary available expertise to avoid an overreliance on group resources, policies and procedures.
4.2 Policies and procedures
Boards should be able to evidence the management of climate and nature risks within their risk management policies, management information and board risk reports. Where material climate and nature risks are identified, the existing risk management policies and procedures may need updating accordingly.
4.3 Risk identification
Boards should seek to identify and understand material climate and nature related financial risks, and how they may impact their business model. Scenario analysis can be used to determine the short and long-term impacts. The relevant regulations and guidance identify categories of risk that the risk management framework should cover at a minimum. Climate and nature risks will likely fall within these established risk categories and should not be considered separately (see table in 2.2.3). Firms should seek to identify sectors with higher or lower exposures to physical and / or transition risks. The risk criteria for this identification may include a range of factors, such as:

Isle of Man Financial Services Authority
Version 1.0 Page 13 of 18
First issued 10 July 2025
 Vulnerability to extreme weather events.
 Level of greenhouse gas emissions.
 Significant resource extraction.
 Level of pollution.
 Land and sea use change.
 Potential exposure to changes in climate-related policy or technology.  Vulnerability to climate-related supply chain changes or disruption.  Vulnerability to climate-related disruption of business activities.  Linkages to unsustainable practices. This may be used to develop sector-specific policies when undertaking business engagements (such as investing, insuring or lending) with that sector, or in understanding their own exposure to climate and nature related risks. Banks and insurers should specifically consider and record any material impact on capital adequacy because of climate and nature risks. Existing ICAAP and ORSA processes should be used to determine this. Firms that are not required to carry out ICAAPs or ORSAs may benefit from adopting a similar approach to recording any material exposures in their risk assessment documentation and how the assessment of those exposures is considered.
4.4 Materiality assessment
Firms should determine the materiality of identified climate and nature risks. These risks can change over time and therefore the materiality assessment may need to be repeated regularly based on forward-looking exposures. Larger firms such as insurers and banks, or businesses where a more significant exposure to climate and nature risks is likely, may wish to carry out a formal materiality assessment. Such a materiality assessment can assist with board and senior management understanding of what risks have been considered and how their materiality has been assessed, as well as how to respond effectively to these risks. An appropriate climate risk materiality assessment may take the following form:

• Material risks feed
  into ORSA and ICAAPs
  4.5 Risk monitoring
  Both qualitative and quantitative approaches should be used to assess and monitor climate and nature risks. This should include developing appropriate and proportionate metrics to measure and monitor these risks. These metrics could be used to assess exposures to certain sectors or geographical locations that pose high climate and nature risk. The Financial Stability Board’s Task Force on Climate￾related Financial Disclosures has issued guidance on the type of metrics that can be used.8 Guidance on nature metrics is being developed. Further information can be found on the taskforce on Nature-related Financial Disclosures website.9 Other quantitative risk metrics could include direct and indirect emissions (i.e. Scope 1, Scope 2 and Scope 3 emissions)10, exposures to physical risks, monitoring potential impacts to business metrics such as credit risk, losses or investment returns and modelling the impact of climate or nature scenarios on returns. Quantitative metrics can help firms understand the potential current and future impacts of climate change on their relevant stakeholders, such as customers and suppliers. To obtain this information, firms should engage with relevant stakeholders to form an understanding of the extent to which the impacts may be material. 8 https://assets.bbhub.io/company/sites/60/2021/07/2021-Metrics_Targets_Guidance-1.pdf 9 https://tnfd.global/ 10 Scope 1 emissions – all direct greenhouse gas emissions arising from a business’ own activities. Scope 2 emissions - indirect greenhouse gas emissions from the use of purchased electricity, heat or steam. Scope 3 emissions - other indirect emissions not covered in Scope 2 that occur in the value chain of the reporting company, including both upstream and downstream emissions. Relevant Scope 3 emissions for finance sector entities includes the Scope 1, Scope 2 and material Scope 3 emissions from businesses to which they have a financial exposure (e.g. through lending activities, insurance products, and investments), or the Scope 3 emissions of emissions-intensive inputs to their businesses.

First issued 10 July 2025
Data is key for firms to better understand the possible impacts of climate change on their operations as well as those of their stakeholders. Data from publicly available and private sources should be utilised, and expertise should be sought where necessary. Firms may also wish to set climate or nature-related targets for their activities. These targets can be useful tools in risk management, as well as for corporate strategy. The target can be a specific level, threshold, quantity of qualitative outcome that a firm wishes to achieve over a defined time horizon, to assist in managing climate or nature related risks and opportunities. Targets, where applicable, should be linked to a firm’s metrics so progress can be measured as well as reflecting overall business strategy and risk-management framework. Targets may reference external benchmarks such as sector, national or international targets.11 Due to the evolving understanding of climate change, firms should ensure that their risk monitoring targets and metrics are updated regularly.
4.6 Internal Controls
4.6.1 Risk controls
Risk mitigation plans should be developed, implemented and monitored where material climate and nature risks have been identified. An example of such a plan could be to reduce concentrations of investments in specific industries which are at risk of becoming stranded assets due to the impact of climate change and transition on that industry. Firms may need to consider standard risk mitigation options such as:
 Reflecting the cost of the additional risk through risk-based pricing measures.  Applying limits on exposures to businesses or industries in higher risk industries or jurisdictions.  Where the risks cannot be adequately addressed through other measures, considering the ability to continue the relationship. Firms should also consider the social benefit of providing services or insurance cover to sectors which assists with the adaption required to mitigate the impacts of climate change and biodiversity loss. For insurance, in particular, adaption can reduce the current risk of such exposures in the future.
4.6.2 Risk reporting
Firms should establish reporting procedures to regularly provide relevant information on material climate and nature related exposures, including risk monitoring and controls, to the Board and senior management. 11 https://tnfd.global/publication/additional-draft-guidance-for-corporates-on-science-based-targets-for-nature-2/

Isle of Man Financial Services Authority
Version 1.0 Page 16 of 18
First issued 10 July 2025
The extent and nature of reporting can be proportional to the nature and magnitude of the risks to which the firm is exposed.
5. Scenario Analysis
Insurers and incorporated banks should carry out appropriate stress and scenario tests of material risks within their ORSAs and ICAAPs12 to assess the impact on their risk profile and business strategies, and to explore resilience to financial losses. The use of scenario analysis and stress testing should be proportional to a firm’s size, business mix and complexity. Due to the differences in climate and nature risks, along with the specific risk drivers, set out in section 2.2.1, firms may need to develop capabilities in scenario analysis of climate and nature risks and may need to seek external assistance with setting and testing appropriate climate and nature related scenarios. In the early stages of development, as capabilities grow, narrative qualitative scenario analysis can be utilised – this is particularly the case for nature loss scenarios which are in their early stages of development internationally. Qualitative scenarios can provide insights into risk transmission and findings can be reflected in business plans, strategies and risk management practices. More advanced scenarios incorporating forward-looking qualitative and quantitative factors should identify and simulate plausible scenarios which are relevant to the firm’s operations. Firms should consider both a shorter-term assessment (if an incorporated bank or insurer, possibly in line with their current ORSA or ICAAP projection period), and a longer-term assessment of future exposures based on a range of potential different climate and nature outcomes, and document accordingly in their risk assessments. The Authority does not currently prescribe any scenarios. Instead, a useful source of potential different climate scenarios as well as guidance as to how to conduct scenario selection and analysis is published by the NGFS13. Nature based scenarios are still in development14 . Scenarios should consider identified material physical risks and transition risks. The impact of the scenarios should be considered on capital adequacy, liquidity, and the ability to meet obligations including those to depositors and policyholders. Firms should maintain appropriate documentation of the method and results of scenario analysis and stress testing, including clear statement of limitations. Material results should be communicated to boards and senior management and used to inform business planning and strategy. 12 Scenario analysis within ICAAPs guidance:

6. Disclosure
There is an increasing demand from investors and stakeholders for disclosure on climate and nature risks and opportunities to enable stakeholders to understand their own risks and opportunities, and to meet their own disclosure requirements. The Authority currently does not mandate sustainability disclosure requirements; however, the introduction of a formal disclosure framework, where disclosure is proportionate, is being considered as part of the Island’s Sustainable Finance Roadmap.15 Despite there being no formal requirement, some firms follow group disclosure requirements and report information required under several jurisdictions’ frameworks, depending on the location of their head office. Firms that currently do not disclose any information on their climate and nature risks and opportunities should consider whether additional, voluntary disclosures could be beneficial to their business, enhancing transparency, and giving confidence to both their internal and external stakeholders and the wider market.16
7. Summary of actions to be taken
In line with existing risk management requirements, firms should, where they do not already do so:
 Identify material climate and nature risks and opportunities that could potentially impact their business strategy / business model and include these in their risk assessment documentation. Where no material climate and nature risks or opportunities are identified, it is likely that no further action is required.  Utilise qualitative and quantitative approaches to measure identified risks.  Determine appropriate qualitative and quantitative metrics to monitor identified risks.  Develop mitigation plans to manage identified material risks.  Update governance and risk management frameworks accordingly.  If appropriate and proportionate to do so, conduct scenario analysis to inform understanding of longer-term risks and opportunities and inform business decisions.  Report the results to the Board and senior management.  If appropriate and proportionate, consider disclosure practices.
