Want to unlock billions in climate finance for emerging markets? Sustainable debt could be the key, but it's not a guaranteed win. A recent BloombergNEF (BNEF) report, "Scaling Sustainable Debt in Emerging Markets," highlights both the massive potential and the current roadblocks in using sustainable debt to bridge the enormous climate financing gap in these regions. This gap is estimated to be in the trillions of dollars, making innovative financial solutions like sustainable debt crucial.
The report, commissioned by the Dubai Financial Services Authority (DFSA) and the Hong Kong Monetary Authority (HKMA), reveals that labeled sustainable debt is already a significant player, funding almost half of all low-carbon energy ventures in the Middle East and North Africa (MENA) and the emerging Asia Pacific (APAC) regions. These financial instruments provide a crucial channel for directing capital towards the energy transition, signaling a robust foundation for future expansion. Consider, for instance, a solar farm project in India or a wind energy initiative in Morocco – sustainable debt could be the financial engine driving these projects forward.
However, here's where it gets controversial... The report also points out that sustainable debt issuance actually slowed down in MENA and emerging APAC in 2025, after hitting record highs in 2024. This slowdown mirrors a global trend, fueled by growing skepticism about the real benefits of labeling debt as "sustainable." This skepticism revolves around factors like pricing advantages and the costs associated with reporting. Are the perceived benefits of going green fading, or are the costs simply too high?
And this is the part most people miss... The report suggests that the "greenium" – the price discount issuers previously enjoyed for labeling debt – has largely disappeared. In some cases, issuers are even paying a premium for green issuance! This shift could be a major deterrent for companies considering sustainable debt options. Why pay more for something that doesn't offer a clear financial advantage?
Despite these challenges, the sustainable finance market remains vibrant, with issuers experimenting with novel structures and regulators actively exploring supportive policies. Labeled debt currently represents only 2.6% of the total debt market in emerging economies, showcasing substantial opportunities for growth. Think of the untapped potential: as these economies develop, the need for sustainable infrastructure and projects will only increase.
So, what can be done? The report emphasizes that regulators and governments have key tools at their disposal to boost the labeled sustainable debt market and tackle climate and sustainability challenges.
One crucial step is government support to offset labeling costs and establish a clear regulatory framework for labeled issuance. The Hong Kong government's subsidy scheme for green and social issuers serves as an excellent example. As of mid-October 2025, over 620 sustainable debt instruments, totaling over $170 billion, had received subsidies in Hong Kong. This demonstrates the tangible impact of government incentives.
Regulators can also stimulate the market by providing clear guidance for issuing labeled debt, encouraging issuers to embrace labeling practices. Policy frameworks, like the Association of Southeast Asian Nations’ sustainable finance taxonomy, assist issuers in identifying green and transitional activities, potentially driving increased issuance. This provides a standardized roadmap for sustainable finance initiatives.
But it's not just about government action. Issuers themselves can innovate by moving beyond conventional labels, tenors, and structures. Social debt, for example, presents a significant growth opportunity. Social instruments account for only 8% of total issuance in these emerging markets since 2020. Considering that regional leaders like South Korea and Japan boast some of the largest social bond markets globally, their experiences could pave the way for success across the broader APAC region.
Consider DP World, a UAE-based logistics and marine port operator, and its blue bond. This highlights the advantage of using specific labels to attract capital for underserved areas of sustainability, such as marine ecosystem conservation, restoration, and sustainable marine transportation. By focusing on a specific environmental challenge, DP World was able to attract targeted investment.
Similarly, Emirates NBD Bank's sustainability-linked loan bond (SLLB) exemplifies the added credibility that innovative labeling structures can bring. Through the use of robust selection criteria, the structure can effectively channel financing to the most impactful sustainability-linked loans. Transparency concerning the specific instruments financed by the SLLB is vital to its success.
Hong Kong's MTR Corporation, a public transportation provider, demonstrated strong investor demand for ultra-long tenors with a green bond and green loan. The company's inaugural 30-year green bond was oversubscribed 5.8 times, highlighting the appetite for long-term sustainable investments.
Mark Steward, Chief Executive of the DFSA, emphasizes the importance of this research in understanding the evolution of sustainable debt in MENA and emerging APAC. He highlights the $94 billion issuance record in 2024 as a reflection of growing investor confidence and market resilience, emphasizing the DFSA's commitment to supporting sustainable and transition finance.
Eddie Yue, Chief Executive of the HKMA, stresses the potential of sustainable debt to bridge the climate financing gap in emerging markets. He highlights Hong Kong's commitment to leveraging its infrastructure and expertise to support emerging markets in achieving their sustainable development goals, given its position as Asia's leading sustainable finance hub.
Jon Moore, Chief Executive of BloombergNEF, underscores the role of sustainable debt in building trust and transparency in the financial market. He commends the efforts of HKMA and DFSA in driving the development of sustainable debt markets, emphasizing the importance of scaling up finance and investment for the energy transition.
Ultimately, the success of sustainable debt in emerging markets hinges on collaboration between governments, regulators, and issuers. By addressing the current challenges and embracing innovation, we can unlock the full potential of this powerful tool to create a more sustainable future.
