Unlocking Climate Action: Sustainable Debt's Role in Emerging Markets
The climate crisis demands urgent action, but financing remains a critical barrier. A recent BloombergNEF (BNEF) report, 'Scaling Sustainable Debt in Emerging Markets,' reveals a powerful solution: sustainable debt. This financial tool is pivotal in bridging the colossal climate financing gap in emerging economies, estimated at multi-trillion dollars.
The Power of Sustainable Debt
In the Middle East, North Africa (MENA), and emerging Asia Pacific (APAC) regions, sustainable debt is a lifeline for low-carbon energy companies, accounting for nearly half of their financing. This debt is not just a financial instrument; it's a catalyst for the energy transition, offering a robust foundation for growth.
Navigating Challenges: Issuance Slowdown
However, the issuance of labeled sustainable debt in these regions slowed in 2025, following a record-breaking 2024. This global trend is attributed to shifting perceptions about the benefits of labeling debt, impacting pricing and reporting costs. Issuers, once incentivized by reduced pricing, now face fading discounts, with some even paying premiums for green issuance.
But here's where it gets controversial: despite these headwinds, the sustainable finance market remains dynamic. Issuers are experimenting with innovative structures, and regulators are stepping up with policy support. The fact that labeled debt constitutes only 2.6% of the debt market in emerging economies underscores the vast untapped potential.
Regulatory Support: Lowering Barriers
Regulators and governments have a pivotal role in promoting climate finance in emerging markets. They can foster the growth of the sustainable debt market by offering solutions to offset labeling costs and providing a clear regulatory framework. The Hong Kong government's subsidy scheme for green and social issuers is a prime example, having supported over 620 sustainable debt instruments worth $170 billion as of October 2025.
Regulators can further drive the market by offering guidance on labeled debt issuance, encouraging issuers to embrace labeling. Policy frameworks, such as the Association of Southeast Asian Nations' sustainable finance taxonomy, can assist issuers in identifying green and transitional activities, potentially boosting issuance.
Beyond Conventional Labels: Innovation Opportunities
Growth opportunities extend beyond traditional green labels and structures. Social debt, for instance, has strong growth potential, yet it only represents 8% of total issuance since 2020 in these emerging markets. Countries like South Korea and Japan, with thriving social bond markets, offer valuable insights for the APAC region.
Moreover, DP World's blue bond demonstrates the power of specificity in labeling. By targeting marine ecosystem conservation and sustainable transportation, it attracts capital to underserved sustainability areas. Emirates NBD Bank's sustainability-linked loan bond (SLLB) showcases the credibility of innovative labeling structures, channeling financing to impactful sustainability loans.
Hong Kong's MTR Corporation's ultra-long tenor green bond and loan also reveal investors' appetite for long-term sustainability investments. The 30-year green bond was oversubscribed by 5.8 times, indicating strong investor confidence.
