The Case for Caribbean Climate Resilience as American Interest

The Caribbean's climate challenge is increasingly an economic and development challenge. These countries face numerous climate shocks while also confronting high infrastructure costs, limited domestic markets, narrow production structures and, in several countries, constrained fiscal space. More investment is required to maintain infrastructure, strengthen resilience, and transition toward lower-carbon and more diversified economies.

Yet the region's available financing remains well below identified needs. One ​​assessment found that the Caribbean’s Small Island Developing States needed about $55.7 billion in climate finance between 2015 and 2030 to meet stated climate objectives. But only about $7.2 billion has been allocated for that period. Other recent regional assessments reinforce this point, including a 2026 joint report by the Organization for Economic Cooperation and Development (OECD) and the Inter-American Development Bank (IDB).

In short, available financing is insufficient relative to need, often difficult to access, and not always structured to enable countries to move from individual climate projects toward broader economic transformation.

The Caribbean is developing institutions, instruments, and partnerships to address these constraints. The Caribbean Development Bank has expanded its climate-financing role, and CARICOM and its financial institutions are developing regional approaches to green finance. The Caribbean Community Climate Change Center (CCCCC), Caribbean Catastrophe Risk Insurance Facility Segregated Portfolio Company (CCRIF SPC), and other regional bodies provide specialized technical and financial capabilities.

The policy challenge is increasingly one of scale, coordination, sequencing, and alignment.

From Climate Finance to Green Industrial Transformation

The Caribbean is not struggling from a lack of investment. Indeed, total investment ​​​​averaged 28% of regional GDP in 2023, above both OECD and Latin American averages. But a significant share of that investment goes to short-term or externally driven needs, including post-disaster reconstruction, rather than sustained investment in productive capacity, infrastructure, and economic diversification.

This challenge is compounded by underdeveloped domestic capital markets and high financing costs, which constrain access to the long-term capital required to address the region’s infrastructure and development needs. Foreign direct investment (FDI) can play an important role in complementing domestic and public investment. When appropriately directed and supported by enabling policy frameworks, FDI can help expand productive capacity, accelerate digital and renewable-energy transitions, diversify exports, and generate quality employment.

Caribbean p​​​​olicymakers should focus on improving the quality and duration of investment, as well as financing conditions and alignment with long-term development priorities. This is central to the region’s ability to translate climate and development finance into sustained economic transformation and greater resilience.

A renewable-energy project can reduce emissions and lower energy costs. But the broader economic opportunity depends on whether Caribbean firms can participate in associated supply chains; whether workers have the necessary skills; whether infrastructure and electricity systems can support investment; whether businesses can access working capital; whether firms can reach regional and external markets; and whether governments have sufficient fiscal space to support enabling infrastructure.

This creates a gap between financing individual climate investments and financing economic transformation. The region needs a financing ecosystem that connects climate and development finance, project preparation, infrastructure investment, private-sector finance, working capital and trade finance, skills and technology, regional market integration, international market access, and debt and fiscal sustainability.

Existing institutions have not necessarily failed to perform these functions. But these capabilities should be more effectively connected around specific investment priorities.

Why This Matters for U.S. Regional Interests

1. Economic resilience: Climate shocks can generate substantial fiscal pressures and disrupt economic activity, particularly in small economies. Greater productive diversification and resilience can reduce Caribbean economies' vulnerability to external shocks.
2. Trade and investment: The Caribbean represents a proximate market and production base for the United States. Greater regional productive capacity can create opportunities for trade, investment, and supply-chain relationships.
3. Energy security: Many Caribbean economies remain highly dependent on imported fossil fuels. Accelerating renewable energy, energy efficiency, and resilient electricity systems can reduce exposure to international energy-price volatility while creating opportunities for investment and technological cooperation.
4. Climate resilience: The Caribbean's climate vulnerability is directly relevant to broader U.S. climate and disaster-resilience objectives. Strengthening adaptation and resilience reduces the economic consequences of future climate shocks.
5. Regional geopolitical relationships: U.S. support for Caribbean-led economic transformation can strengthen and expand regional partnerships.

The Role of Existing Regional Institutions

Policy responses should build on, rather than duplicate, existing regional capabilities. The Caribbean already possesses a relatively sophisticated institutional ecosystem, which includes:

• The CDB has an established mandate for regional development finance, is already expanding its climate and private-sector financing activities, and is developing project-preparation and regional climate platforms intended to address pipeline constraints affecting climate investment.
• CARICOM provides an important framework for regional market integration and policy coordination.
• The ​CCCCC ​and ​CCRIF SPC​ are specialized regional institutions that provide important technical capabilities in climate policy, resilience, risk management, and disaster financing.
• Central banks, national development banks, public utilities, investment agencies, and private financial institutions are also critical to translating regional and international financing into domestic investment.

The objective should be to strengthen the connections among these institutions — not to designate one institution as the sole regional conduit.

Policy Recommendations

For the U.S. State Department:

• Support Caribbean-led coordination of existing financing mechanisms and multilateral institutions, and regional efforts to better connect climate finance, development finance, project preparation, private investment, trade finance, and market access.
• Support greater access to appropriately structured climate finance. This means:
• • Greater grant and concessional financing for vulnerable small economies
  • Simplified access procedures
  • Stronger project-preparation support
  • Increased use of guarantees and risk-sharing instruments
  • Financing structures that recognize the fiscal constraints of highly indebted countries
  • Greater predictability of climate finance

For the Office of the U.S. Trade Representative:

• Align trade policy with green economic transformation in the Caribbean. Trade policy can complement climate and development finance by reducing demand uncertainty for Caribbean producers. The United States should:
• • Explore opportunities to facilitate market access for climate-aligned goods and services
  • Strengthen trade facilitation
  • Support standards recognition and regulatory cooperation
  • Facilitate participation in regional and global green supply chains
  • Identify opportunities for U.S. firms to invest in Caribbean green industries

The objective should be to create conditions under which Caribbean governments and firms can identify and develop commercially viable areas of competitive advantage.

For Congress:

• Support stronger regional and multilateral financing capacity. Congress should encourage U.S. representatives to multilateral institutions to support financing approaches that reflect the circumstances of small, climate-vulnerable economies. This could include support for:
• • Expanded concessional financing
  • Project-preparation facilities
  • Guarantees and risk-sharing mechanisms
  • Climate-resilient infrastructure
  • Private-sector mobilization
  • Regional approaches that reduce transaction costs for small economies
• Measure development assistance by transformational outcomes. U.S. development and climate programs could place greater emphasis on outcomes such as:
• • Investment mobilized
  • Productive capacity created
  • Private capital leveraged
  • Energy-import dependence reduced
  • Export capacity expanded
  • Resilience strengthened
  • Quality employment generated
    

The objective would be to complement traditional measures of funds disbursed with measures of economic transformation and resilience.

For the U.S. Treasury and Broader Multilateral Engagement:

• Promote financial architecture compatible with Caribbean circumstances. Through U.S. engagement with the International Monetary Fund, World Bank, and other international financial institutions, policymakers could support approaches that better recognize the interaction between climate vulnerability, debt sustainability, and productive investment. This includes encouraging debt sustainability assessments and financing frameworks that properly account for the economic returns and resilience benefits of climate investment.
• Leverage the G20 and other international groupings. The United States can use its influence to advance reforms that improve the availability, affordability, and accessibility of development and climate finance for small, climate-vulnerable economies. This should include:
• • Stronger coordination among multilateral development banks, vertical climate and environmental funds, and national development banks
  • Greater use of guarantees, risk-sharing, and blended finance
  • Improved project-preparation facilities
  • Financing approaches that better account for climate vulnerability, debt sustainability, and the investment needs of small economies

The United States could also use its participation in other groupings to build greater international support for these approaches. The objective would be to ensure that Caribbean priorities are reflected in broader reforms to the international financial architecture.

Conclusion

The Caribbean faces a substantial gap between its climate and development investment needs and the volume, terms, and accessibility of available finance. But it is not starting from scratch. Regional and national institutions are already developing climate-finance pipelines, green-finance frameworks, resilience instruments, project-preparation facilities, and economic diversification strategies.

The United States should strengthen this emerging architecture rather than create a parallel one. For U.S. policymakers, this offers a practical avenue for supporting regional economic resilience while advancing interests in trade, energy security, climate resilience, and stable economic relationships with Caribbean partners.

The central challenge for U.S. policymakers is to devise policies that help Caribbean countries mobilize more of the right kind of finance through institutions with regional legitimacy and capacity, and connect that finance to productive investment, economic diversification, and resilient growth. A Caribbean region with productive economic capacity, reduced debt stress, climate-aligned growth, and reduced migration pressure would advance U.S. interests in several ways.
