CLIMATE BONDS INITIATIVE REPORT OF THE TRUSTEES space. They have also defined a process to support regional teams in planning and executing policy work and launched a Policy Network for all staff working on policy issues. Optimise We laid out a plan before the start of the year to derisk the organisation's finances and create a solid financial platform for activities going forward. The 4 constituents of the plan are: Grow independent and mission aligned commercial I repeat incomes, such as data services, network membership, certifications. capacity building and lechnical assistance. Extend our funding commitments, moving from isolated project funding arrangements to programmatic or 'lhemed' agreements covering multiple years. Expand the number of funding partners. reducing our dependence on a small number of large donors. Increase the flexibility of our cost base by developing wider partnership collaborations, OLrtsourcing services and increase contract flexibility- To achieve this, we had lo make organisational changes, which unfortunately led to several redundancies. We also made significant appointments adding lan Howard as Director of Climate Services at the end of 2023. to restruclure our commercial operations. More recently, in January 2025, Ina Hoxha was appointed Chief Investment OffI￿r (Deputy CEO) and Biathnaid Byrne was brought in as Director of Global Strategic Engagement. As well as financial restructuring and significant organisational changes, we have improved many other areas of the business, such as our data platform, our communications and marketing, resource management and financial reporting systems. We are now seeing the benefit of these actions as we progress through 2025. Key Performance Indicators (KPIS) In 2024, Climate Bonds Initiative made strong progress in advancing sustainable finance globally. Key achievemenls included continued growth in green bond issuance, expansion of its international footprint, and increasing alignment with its standards and methodologies. 12

New Standards l Taxonomies were created in 15 countries At the end of De￿rnber 2024, 82 % of thematic debt volume captured by Climate Bonds was aligned with ils database methodologies. Climate Bonds Global Slate of the Market 2023 report was downloaded from the Climate Bonds website 5.000 times. The number of network members fell from 95 at the end of 2023 10 87 at the end of 2024. as we restructured the product and focused on higher value for clients. Average income per member increased by 9 % and overall Partnerships income remained at £1.23m Climate Bonds Iniliative continues to increase its geographical reach. At the end of the year we had staff based in 25 countries and were actively managing projects across all 5 continents. Income growth of 8% achieved. Financial review The Balance Sheet is shown on page 25 of this document, with further analysis shown in notes 12-21 on pages 2742. For the year ended 31 December 2024. the Charity had income of £9.5m (2023.. £8.8m) and incurred expenditure of £10.2m (2023: £9.4m). Climate Bonds continued to grow significantly in 2024, increasing our income by 8 %. We worked on 79 projects across Latin America, India. China, Europe. Australia and South East Asia. Climate Bonds unrestricted funds at the end of 2024 was £0.9m (2023: £1.5m). Net assets of the Charity at the year-end amounted to the same £0.9m (2022: £1.6m). 2024 was a challenging year financially for Climate Bonds, having to readjust the organisation and our processes to accommodate 6 years of growth totalling nearly 400 % , 13

CLIMATE BONDS INITIATIVE REPORT OF THE TRUSTEES greater regulatory and compliance requirements globally. and the end of some favourable grant arrangements with our largest funding partners. Action was taken to minimise the impacl of these changes without compromising our mission,. to de-risk our finances, improve the reliability of our income streams and reduce our cost base. In the second half of the year and into 2025. with the help of our funding partners, we have seen the very positive impact of these changes, and we are now well on track to restore reserves to the target set by the Trustees. Future Plans A specific target for 2025 is to develop and enhan￿ our toolkit to address adaptation and resilience. Going forward, Ina Hoxha is leading a major strategic exercise, with the support of our key funders and a top strategy consultant, to develop our programmes to ensure we deliver optimal impact across all that Climate Bonds works and engages on. We will define the macro landscape, understand the pain points and needs of our customers and the wider market, and identify priorities where Climate Bonds can have greatest impact. We will then improve the strategies to best deliver in these areas and establish the organisation, workplans and timelines to implement accordingly. Public Benefit Statement The Charity has regard to the guidan￿ on public benefit published by the Charity Commission. Climate change is an enormous worldwide challenge that will affect nations, communities and societies. Addressing that challenge requires huge levels of financing immediately, as well as in the near to medium future. Climate and green bonds have the potential to make a major contribution to that financing. For the climate bonds market to grow, investments need to be underpinned by confidence in the green credentials of bonds. The Charity manages 14

CLIMATE BONDS INITIATIVE REPORT OF THE TRUSTEES the Climate Bonds Standards that play a vital role in ensuring that there is confidence and credibilrty in these investments. Details of activities in furtherance of public benefit are set out in this report. Principal Risks and Uncertainties The Trustees have assessed the major risks that the Charty faces in relation to its operations and finances and are satisfied that the Charity is taking the action necessary to mitigate its exposure to these risks. A risk assessment register is being maintained and updated on a regular basis. The main risks and uncertainties facing the Charity relate to: Financial stability: Ensuring that the Charity's sources of income continue in the future requires maintaining a range of income streams, maintaining and extending good relationships with financial supporters, sound financial governance, and continuing to provide guidan￿ and encouragement that is respected and wel received by the inlemational financial markets and governmental regulators. Lack of engagement from potential bond issuers: If bond issuers do not recognise the value of issuing green bonds the charity's overall objective to stimulate green growth is diminished. Lack of engagement from other financial market stakeholders such as investors, underwriting banks and domesticlinternational development banks. Lack of participation by policymakers and regulators because of disinterest in engaging with our outputs and advocacy. This could put the Climate Bonds Initiative's leading international standing at risk. Reserves Policy Climate Bonds aims to maintain reserves above a minimum level deemed appropriate by the Board of Trustees. The reserves target will be reviewed quarterty and reported to the Trustees at each Board meeting. The target may be adjusted based on the organization's 15

CLIMATE BONDS INITIATIVE REPORT OF THE TRUSTEES review and will be influenced by various factors, including: Economic conditions Fluctuations in income and expenditure Anticipated future commitments Potential risks and uncertainties The strategic plan and organizational priorities Calculation of Minimum Reserves Targel: The Minimum Reserves Target for Climate Bonds is reviewed at least every year by the Finance Steering Committee and approved by the Board of Trustees. The minimum resenie target will be based on a calculation of the emergency wind-up costs of Climate Bonds in the unlikely event of a major, adverse and irrecoverable failure. The Board will also review other reserve calculations lo ensure that the minimum reserve tsrget is not significantly out of line with these altemative minimum reserve calculations. These include: To maintain cu￿ent levels of activity in the event of a major disruption to Income Aggregate net cosl of risks based on impact and probability of negative events Appropriate number of months unrestricled expenditure The minimum reserve target at the end of 2024 was assessed to be £600,000. The actual reserves were £917,029. The Trustees detemiined that reserves, although above the minimum, were too low, particularly as Climate Bonds had grown significantly, and therefore set a target reserve level of £1.5m by the end of 2025. Structure, governance and management Climate Bonds Initiative is a company limited by guarantee and a registered charity. The Charity's memorandum and articles of association are its primary governing documents. The Trustees of Climate Bonds Initiative are also the directors of the charitable company for the purposes of company law.

CLIMATE BONDS INITIATIVE REPORT OF THE INDEPENDENT AUDITOR YEAR ENDED 31 DECEMBER 2024 Auditor's responsibilities for the audit of the financial statements We have been appointed auditor under the Companies Act 2006 and section 151 of the Charities Act 2011 and report in accordance with those Acts and relevant regulations made or having effect thereunder. Our objectives are to obtain reasonable assurance about whether the financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an auditor's report that includes our opinion. Reasonable assurance is a high level of assurance but is not a guarantee that an audit conducted in accordance with ISAS (UK) will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these financial statements. Irregularities, including fraud. are InStan￿S of nonwcompliance laws and regulations. We design procedures in line with our responsibilities, outlined above, to detect material misstatements in respect of irregularities, including fraud. The exient to which our procedures are capable of detecting irregularities, including fraud is detailed below.. We obtained an understanding of the group and parent charitable company and the sectors in which they operate to identfy laws and regulations that could reasonably be expected to have a direct effect on the financial statements. We obtained our understanding in this regard through discussions with management. industry research, application of cumulative audit knowledge and experience ofthe sector. We determined the principal laws and regulations relevant to the group and parent charitable company in this regard to be those arising from Companies Act 2006. Charities Act 2011, Charities (Accounts and Reports) Regulations 2008. employee and tax legislation. We designed our audit prO￿dureS to ensure the audit team considered whether there were any indications of non-complian￿ by the group and parent charitable company with those laws and regulations. These procedures included. but were not limited to.. enquiries of management., and review of minutes We also identified the risks of material misstatement of the financial statements due to fraud. We considered, in addition to the non-rebuttable presumption of a risk of fraud arising from management override of controls, that provisions for doubtful debts and other liabilities as well as accruals and deferrals could be subject to management bias. We have reviewed the calculations for provisions and Ihe assumptions involved. We also reviewed the application of cut-off through accrued and deferred income. No issues were identified. As in all of our audits, we addressed the risk of fraud arising from management override of controls by performing audit procedures which included but were not limited to.. the testing of journals., reviewing accounting estimates for evidence of bias,. and evaluating the business rationale of any significant transactions that are unusual or outside the normal course of business. No issues were identified in our review. Because of the inherent limitations of an audit, there is a risk that we wll not detect all irregularities. including those leading to a material misstatement in the financial ststements or non-compliance with regulation. This risk increases the more that compliance with a law or regulation is removed from the events and transactions reflected in the financial statements, as we will be less likely to become aware of instances of non-compliance. The risk is also greater regarding irregularities occurring due to fraud rather than error, as fraud involves intentional concealment. forgery, collusion, omission or misrepresentation. A further description of our responsibilities for the audit of the financial statements is located on the Financial Reporting Council's website at.. www.frc.or .uklauditorsres onsibilities. This description forms part of our auditor's report. 22

The trustees have considered the charity's ability to meet its liabiltties as they arise over the foreseeable future to July 2026. being 12 months from the date of approval of these financial statements. Accordingly, financial forecasts and cash fl¢)w projections have been prepared for this period. The trustees recognise that in a period of growth there are some uncertainties that exist in the assumptions underlying these forecasts. principally concerning income generation and have identified actions to be taken as appropriate risk mitigation should these assumptions and forecasts not be adequately achieved. Income Recognition All incoming resources are included in the Statement of Financial Activities {SoFA) when the charity is legally entitled to the income, after any perfomiance conditions have been met, when the amount can be measured reliably and when it is probable that the income will be received. For donations to be recognised the Charity will have been notified of the amounts and the settlement date in writing. If there are conditions attached to the donation and this requires a level of performance before entitlement can be obtained then income is deferred until those conditions are fully met or the fulfilment of those conditions is within the control of the Charity and it is probable that they will be fulfilled.

CLIMATE BONDS INITIATIVE NOTES TO THE FINANCIAL STATEMENTS AT 31 DECEMBER 2024 1. Accounting Policies {continued) Annual partner subscriptions are recognised over the 12-month period to which they relate, with the balance at the year-end included as deferred income. Interest on funds held on deposit is included when receivable and the amount can be measured reliably by the Charity., this is normally upon notification of the interest paid or payable by the bank. On receipt, donated professional services and donated facilities are recognised as gffts in kind on the basis ofthe value of the gift to the Charity which is the amount the Charity would have been willing to pay to obtain services of facilities of equivalent economic benefft on the open market., a corresponding amount IS then recognised in expenditure in the period of receipt. Expenditure Recognition All expenditure is accounted for on an accruals basis and has been classified under the headings that aggregate all costs related to the category. Expenditure is recognised where there is a legal or constructive obligation to make payments to third parties, tt is probable that the settlement will be required, and the amount of the obligation can be measured reliably. Redundancy and tennination payments are recognised immediately upon becoming a constructive obligation. Expenditure is categorised under the following headings.. Costs of raising funds includes are those costs inCu￿ed in attracting donations, and those incurred in trading activities that raise funds.. and Expendf(ure on charitsble activities includes expenditure associated with the main objectives of the charity and include both direct costs and support costs relating to these activities. Support costs allocation Support costs are those that assist the work of the charity but do not direclly represent charitable activities and include office premises costs, finance, HR, ISIIT, legal and govemance costs and management and administration costs. They are incurred directly and necessarily in support of expenditure on the objects of the charity. Where support costs cannot be directly attributed to particular headings they have been allocated to expenditure on charitable activities on a basis consistent with use of the resources. Govemance costs are those incurred in connection with the running of the Charity and compliance with constitutional and statutory requirements. The analysis of these costs is included in notes 7 and 8. Intangible fixed assets Intangible fixed assets are assets that do not have physical substance but are identifiable and are controlled by the charity through custody or legal rights. Intangible fixed assets are recorded at historical cost and amortised on a straight-line basis over 4-5 years. Development costs that are direcuy attributable to the design and testing of identifiable and unique sofvare products controlled by the Charity are recognised as intangible assets when the following criteria are met..

CLIMATE BONDS INITIATIVE NOTES TO THE FINANCIAL STATEMENTS AT 31 DECEMBER 2024 1. Accounting Policies {continued) Other development expenditures that do not meet these criteria are recognised as an expense as incurred. Development costs previously recognised as an expense are not recognised as an asset in a subsequent period Tangible Fixed Assets and Depreciation Tangible fixed assets are stated at cost or net realisable value after depreciation. The cost of minor additions or those costing less than £500 are not capitalised. Depreciation is provided at rates calculated to write off the cost or valuation of fixed assets, less their estimated residual value, over their expected useful lives on a straight-line basis: Plant and machinery Office equipment 200 200 Debtors and creditors receivable I payable within one year Debtors are recognised when the Charity is legally entitled to the income after any performance conditions have been met, the amount can be measured reliably, and it is probable that the income will be received.

Funds and Fund Accounting Unrestricted funds are available for use at the discretion of the Trustees in furtherance of the general objective of the charity and which have not been designated for other purposes. Restricted funds are funds which are to be used in accordance wth specific restrictions imposed by donors orwhich have been raised by the Charity for particular purposes.
