Unlocking the potential of sustainable bonds for financing climate resilience: the Climate Bonds Resilience Taxonomy

Today has seen the launch of the Climate Bonds Resilience Taxonomy (CBRT) during New York Climate Week. This exciting development offers the potential to scale up market action on financing climate resilience (also referred to as adaptation) by providing clear and consistent definitions of climate resilience investments – in other words, a common vocabulary for climate resilience financing that can be used by broad range of stakeholders including investors, issuers, regulators and policymakers.

The CBRT builds upon Climate Bonds’ extensive experience of taxonomy development and extends their existing Climate Bonds Taxonomy into the increasingly urgent, but comparatively under-funded, area of climate resilience. Cadlas is pleased to be the Lead Technical Partner on this ground-breaking initiative, having worked closely with Climate Bonds since 2022 to bring in our extensive, practical experience of climate resilience financing.

The sustainable bonds market represents a significant source of financing for sustainable development, with total sustainable bond issuances now exceeding USD 5 trillion. However, only a small fraction of the capital raised through these issuances currently addresses climate resilience. While Climate Bonds’ analysis suggests that around 19% of labelled green bond issuances include climate resilience (or adaptation) as an eligible use of proceeds (UoP), evidence suggests that only a small fraction of this financing is being challenged into climate resilience investments.

Nonetheless, sustainable bonds are potentially a key instrument for mobilizing investment in climate resilience. Since the City of Gothenburg first included adaptation as an eligible UoP in its 2013 green bond issuance, market activity has progressively increased so that today around 2,500 sustainable bonds issuances have included adaptation as an eligible UoP, while a total volume of just over USD 1 trillion. While most of this activity has taken place in Europe, North America and the Asia-Pacific (APAC) region, there is a need for greater action in Africa, Latin America & the Caribbean (LAC), and the Middle East & North Africa (MENA) regions, where sustainable bond volumes with adaptation UoP remain relatively low despite these being some of the most climate-vulnerable regions of the world with significant climate resilience investment needs.

This highlights the need for much greater flows of financing for climate resilience, as the frequency and severity of climate change impacts – and their economic and human costs – continue to accelerate. For example, the United Nations estimates that developing countries need up to 18 times more adaptation finance than is currently provided. Furthermore, at present more than 98% of reported adaptation finance is provided by public institutions such as development finance institutions (DFIs), which highlights the need for much greater action on mobilising private finance for climate resilience.

An important obstacle to private finance mobilisation for climate resilience has been a lack of clarity on definitions and criteria for climate resilience investments. ​This creates uncertainty for both investors and issuers and hinders the flow of capital.​ While sustainable finance taxonomies can play an important role in directing private and public investments toward sustainability goals, they have hitherto not given due attention to climate resilience as an investment theme.

To date, climate resilience has tended to take a back seat to ​climate mitigation (or decarbonisation) objectives in sustainable finance taxonomies, with a lack of consistency in the sectoral coverage and breakdown of climate resilience financing. This has been compounded by process-based definitions that are difficult for users to apply, and a lack of clear eligibility criteria for determining whether an investment is meaningfully contributing to climate resilience.

The CBRT directly addresses these challenges by providing a credible classification system for climate resilience investments. It offers focused, detailed guidance on climate resilience, an area often under-prioritised or addressed only broadly in many existing taxonomies. The CBRT provides clear, consistent and comprehensive coverage of climate resilience investments based on six Climate Resilience Themes. This covers a broad range of investment types ranging from financing the adoption of specific climate resilience measures within investments to financing economic activities that provide A&R solutions​.

The CBRT fills a critical market need for a common foundation that helps investors identify and scale up finance for a wide range of investments that genuinely contribute to building climate resilience. It addresses three critical gaps:

1. Clear, Science-Based Definitions and Criteria: The CBRT provides clear, science-based definitions and criteria for identifying investments that substantially contribute to climate resilience. This is essential for overcoming the lack of clarity that has hindered resilience finance flows to date.
2. Navigating the Regulatory Landscape: The CBRT helps investors and companies navigate the evolving regulatory landscape. It aligns with and advances beyond regulatory standards like the EU Sustainable Finance Taxonomy, providing a rigorous, globally applicable framework for demonstrating the climate resilience credentials of investments.
3. Flexibility and Adaptability: The CBRT has been designed to be flexible and adaptable to diverse country contexts and investor needs. This is crucial for building resilience, which requires tailored approaches that reflect local vulnerabilities and priorities. The format of the CBRT also allows for further improvements and tailoring to be added over time.

The next exciting chapter in the CBRT story begins now, as it begins to be taken up and put to use by issuers, investors, regulators, policymakers and others. The CBRT will not only enhance transparency for investors by eliminating certain information asymmetries but also support the alignment of global capital flows with local resilience needs and opportunities underpinned by rigorous, science-based eligibility criteria.

As Cadlas continues to collaborate with partners across the finance landscape to enhance resilience financing in various country contexts and investor mandates, we are confident in the CBRT’s applicability across multiple use cases – particularly as it relates to the sustainable debt market. By supporting a range of issuers, investors and other participants in applying and using the CBRT, we can enhance the effectiveness and impact of climate resilience investments, driving more capital towards projects that are crucial for adapting to and mitigating the effects of climate change.

Cadlas is committed to fostering a resilient future by enabling more informed and impactful investments in climate adaptation and resilience. Stay tuned for more updates on how the CBRT is set to transform the landscape of climate finance.

Basing investment decisions on climate adaptation and resilience impact

As investors become increasingly aware of the implications of our changing climate, there is a growing need for more information about the positive adaptation & resilience impacts of investments.

Private investors are increasingly aware of emerging investment opportunities in adaptation & resilience, with the Bank of America forecasting that the global market for adaptation & resilience may reach USD 2 trillion by the middle of this decade, and MSCI estimating that 11% of publicly listed companies deliver products and services that contribute towards adaptation & resilience.

Information about the positive adaptation & resilience impacts of investments can help to engage private investors and mobilise finance for urgently needed investments in adaptation & resilience.

But private investment in adaptation & resilience is held back by a lack of clear, practical and investor-relevant adaptation & resilience metrics that investors can use to identify, appraise and prioritise investments that make meaningful contributions towards adaptation & resilience​.

Therefore Cadlas is pleased to have worked with the Adaptation & Resilience Investors Collaborative (ARIC) and the United Nations Environment Programme Finance Initiative (UNEP-FI) to develop guidance for investors on the assessment of adaptation and resilience impact in private investments. This guidance, which is available here, sets out a practical framework for assessing adaptation and resilience impact across a broad range of investments using a set of clear, consistent and investor-relevant metrics.

Assessing adaptation & resilience impact in private investments: new guidance for investors

Cadlas is pleased to have provided technical support to the Adaptation & Resilience Investors Collaborative (ARIC) for the development of a framework for assessing the positive impact of private investments towards climate adaptation and climate resilience goals.

This leverages the experience of impact investing to set out a clear framework to help investors measure and manage the way that their investments contribute towards adaptation and resilience.

As private investors become more aware of the scope for investment in adaptation & resilience interventions and solutions, there is an increasing need for meaningful and consistent information about the positive contributions of those investments towards the climate resilience of people, the planet and the economy.

Measuring impact for scaling up investment in climate resilience

Investors need clear, consistent and comparable information about the impact of their investments in order to allocate capital towards effective climate resilience responses and solutions. Cadlas is pleased to be working with the Adaptation and Resilience Investor Collaborative (ARIC) and the United Nations Environment Programme Finance Initiative (UNEP-FI) in an important initiative to advance the measurement of climate resilience impact.

Cadlas collaborates with Climate Bonds on the Development of a Climate Resilience Taxonomy for Sustainable Bonds

As the impacts of climate change become more evident and increasingly material for governments and companies alike, the need to identify and scale up sources of finance for investment in climate resilience becomes ever more pressing.

Green, social, sustainable and sustainability-linked (GSS+) bonds offer huge potential for accessing capital markets for scaling up urgently needed investment in climate resilience. The USD 3.7 trillion GSS+ debt market enables projects and entities such as corporates, sovereign and sub-sovereigns to access finance for sustainable investments in support of the low-carbon transition, social objectives or other sustainability themes – including climate resilience.

Climate resilience already features in GSS+ bonds, with 19% of GSS+ debt instruments having some degree of climate resilience UoP. Recent examples of issuances covering climate resilience include New Zealand’s sovereign green bond and the Arizona Industrial Development Authority’s sustainability-linked bond. In addition, dedicated climate resilience (or climate adaptation) bonds have been issued by the EBRD (2019) and the AIIB (2023).

However, in order to realise the potential of GSS+ debt instruments for financing climate resilience, a clear and systematic framework for issuers and investors is required. This is why Cadlas is pleased to have supported Climate Bonds on the first phase of the development of their Climate Resilience Taxonomy for sustainable bonds. The Climate Bonds Climate Resilience Taxonomy White Paper sets out a clear, upstream framework for defining climate resilience investments that may be eligible for GSS+ bond issuances oriented towards climate resilience.

The White Paper identifies seven ‘climate resilience themes’, covering resilient agri-food systems, resilient cities, resilient health, resilient industry and commerce, resilience infrastructure, resilient nature and biodiversity, and resilient societies. Across those themes, investments may be categorised according to the level of assessment that they require – enabling those investments with clear climate resilience benefits and low risk of significant harm to other sustainability objectives to move ahead more quickly.

Establishing a common language for issuers, investors and other stakeholders to use will be instrumental for harnessing the potential of GSS+ debt instruments for financing climate resilience. The White Paper lays out a solid foundation for the further development of this work over the next few years.

Climate resilience and sustainable finance: will Cinderella go to the ball?

Climate resilience – or adaptation – has been referred to as the Cinderella of climate action. Is it time for her to go to the sustainable finance ball?

We’ve seen important progress in the mainstreaming of physical climate risk information into financial decision-making over recent years. In 2017, the TCFD recommendations created space for information about physical climate risks – and also related opportunities – in climate-related financial disclosures. This was advanced further through the 2021 TCFD guidance on metrics, targets and transition plans, and has now been mainstreamed into the 2022 ISSB draft guidance on climate-related disclosures. As a result, there is now more information available about how financial and non-financial firms are affected by physical climate risks, with the TCFD’s 2022 Status Report finding that 21% of asset managers and 36% of asset owners were reporting their exposure to physical climate risk. Ratings agencies have internalised physical climate risk information into their credit rating methodologies, and a range of service providers and open-source platforms on physical climate risk information have emerged. Furthermore, financial supervisors in a number of jurisdictions have integrated physical climate information into their supervisory requirements on climate-related risk disclosure, for example the ECB, the Bank of England, as well as international bodies such as the NGFS and the Basel Committee on Banking Supervision.

This is good news for market action on climate resilience – also referred to as adaptation. Robust information on physical climate risks is the foundation stone for managing those risks, and for building resilience to them. But there is a kind of asymmetry in the information flows available to investors at present. Investors are now getting some information on reasons not to invest because of exposure to physical climate risks but are getting much less information on reasons to invest because of the potential to contribute positively towards building climate resilience. In fact, more information about physical climate risks in the absence of complementary information about the positive contributions of investments towards climate resilience could even drive finance away from where it is most needed. This is sometimes referred to as capital flight – raising the cost or capital for climate-vulnerable sectors or countries, for example small island developing countries. This contradicts the need for significantly scaled-up investment in climate resilience investment, which the United Nations estimate as up to USD 340 billion per year by 2030.

Regulatory frameworks for sustainable finance have evolved significantly in recent years – but what potential is there for these to facilitate greater investment in climate resilience? To date, sustainable finance has focused principally on decarbonisation, based on the logic that capital should be driven towards addressing the root cause of climate change by reducing GHG emissions. But the emerging sustainable finance architecture also has the potential to address the other climate change imperative – the need to cope with the inevitable impacts of climate change. These will be significant even under a 1.5^oC scenario, with the European Environment Agency estimating adaptation finance needs of EUR 40 billion per year under a 1.5^oC scenario in Europe alone. Climate resilience features prominently in the EU Sustainable Finance Taxonomy, which identifies adaptation as one of its six sustainability objectives. However, the role of climate resilience in the application of the EU Taxonomy appears to be limited to a do no significant harm function only. There is very little evidence of sustainable finance being defined on the basis of a substantial contribution to adaptation. In fact, the EU’s Platform on Sustainable Finance has recently pointed out that urgently needed adaptation investments may be disincentivised by the way that the Taxonomy requires users to select one sustainability objective only, which is usually mitigation due to the overwhelming market interest in decarbonisation. Other building blocks of the EU sustainable finance approach, such as the Sustainable Finance Disclosure Regulation (SFDR) and the Corporate Sustainability Reporting Directive (CSDR), fail to provide clear entry points for climate resilience as a basis for defining sustainable finance or reporting corporate action on sustainability.

So what are the ways in which the momentum on sustainable finance can also advance urgently needed action on climate resilience?

Firstly, recognise that climate resilience and decarbonisation objectives are not in opposition to each other, but can be and should be aligned. Advancing climate resilience does not mean diluting ambition to stay under 1.5^oC. Significant investment in climate resilience will be needed even under a 1.5^oC scenario, but the more that we overshoot 1.5^oC, the greater still those climate resilience investment needs will be.

Secondly, make space for climate resilience in sustainable finance definitions and labels. Investments that make meaningful contributions towards addressing physical climate risks and building the resilience of people, nature or the wider economy should be able to be identified as sustainable investments – with clear safeguards in place to eliminate greenwashing and ensure that other sustainability objectives, including decarbonisation, are respected. For instance, it will be interesting to see whether climate resilience will be considered under the sustainable impact label that is being considered under the UK’s proposed Sustainability Disclosure Requirements.

Thirdly, develop and build consensus around clear, understandable, and consistent impact metrics that investors can use to assess the contribution that investments make towards climate resilience. Together with the rapidly expanding availability of physical climate risk information, these could help to inform capital allocation that supports climate resilience goals. These metrics should be developed with clear reference to the evolving regulatory context for sustainable finance, to ensure relevance and usefulness for as wide a range of investors as possible.

Climate resilience is sometimes referred to as the Cinderella of climate finance – dutifully clearing up in the background, while her louder and pushier sisters hog the limelight. But with climate change impacts already affecting the lives of millions, and the need for scaled up investment in climate resilience no longer a distant prospect, it’s an issue that can no longer be sidelined in the sustainable finance discussion. It’s time for Cinderella to go to the ball.
