Category 5 Hurricane Melissa made landfall in Jamaica on October 28, becoming the most powerful storm to hit the island. It came a mere 15 months after Hurricane Beryl devasted western Jamaica. In 2019, Hurricane Dorian slammed into the Bahamas, with losses estimated at $3.4 billion, or 25% of GDP. In 2017, Hurricane Maria devastated Puerto Rico, with the cost of recovery exceeding $130 billion.

In the Caribbean, climate change is an issue of survival. Simply put, the repeated disasters are unaffordable, ravaging basic infrastructure and siphoning scarce public funds from public health and education Not surprisingly, as COP30 begins this week in Belém, Brazil, Caribbean leaders are desperate for progress, and eager to play a leadership role.

Who Pays?

In 2022, Prime Minister of Barbados Mia Mottley launched the Bridgetown Initiative, a bold agenda to transform international financial architecture so that vulnerable economies could invest in  resilient infrastructure and emerge from climate disasters with their national finances intact. The latest version, launched in 2024, aspires not only to fund, but to reinvent the systems that finance climate action in small island developing states. In doing so, it frames climate finance not as charity, but as strategic investments and risk management.

Aside from reforming multinational development banks’ lending frameworks, the Bridgetown Initiative proposes novel financial instruments, including for addressing rising sovereign debt in countries beset by natural disasters. Greater use of debt-for-nature arrangements, for example, would reduce debt burdens in exchange for national investments in climate or biodiversity conservation projects. Commonly known as green/blue bonds — green for clean energy and forest preservation, blue for marine protection — Latin America and Caribbean countries are pioneers in experimenting with these tools.

Ecuador, for example, completed one of the largest debt-for-nature swaps, generating $1.6 billion in savings and channeling funds to protect the Galápagos islands and Amazon rainforest. In 2024, Costa Rica issued its first blue bond designed to support sustainable fisheries and coastal agriculture. Barbados has worked with the Inter-American Development Bank and The Nature Conservancy to free up $165 million through a debt-for-climate-resilience swap. For its part, The Bahamas refinanced its external debt to make available $100 million for responding to climate change.

COP30 and Beyond

To get big ideas off the ground, global gatherings such as the Conference of the Parties to the United Nations Framework Convention on Climate Change (COP30) are indispensable — even when diplomacy can be sluggish, and not all major players are disengaged. U.S. backpedaling on climate commitments has dampened global momentum, a stark difference from 10 years ago when U.S. Secretary of State John Kerry led the world in negotiating the landmark Paris Agreement to limit the effects of climate change. Even so, COP30 offers space for other countries to step up, including in the Caribbean.

At its core, the Bridgetown Initiative argues that the Caribbean has contributed minimally to global greenhouse gas emissions but suffers disproportionate consequences. Adaptation and resilience cost money, and it is often the poorest countries that spend the most, further stunting their development. To cover the cost, these governments struggle to find affordable loans.

In response, the Bridgetown agenda would give vulnerable countries new financial resources and impose greater burden sharing on larger economies, such as the United States, China, and India, which produce most of the world’s greenhouse gas emissions.

Money Talks

Already, the Bridgetown Initiative has catalyzed reforms. The World Bank, for example, reformed its mission to incorporate Bridgetown Initiative ideas, and the International Monetary Fund launched a $40 billion Resilience and Sustainability Trust Fund that promotes climate resilience in developing nations.

Major challenges remain, however, notably the need to make debt restructuring and swaps mainstream. Multilateral development banks need to do more to provide loans with lower interest rates for countries vulnerable to climate change. Lastly, wealthy countries must fight donor fatigue that has been creeping into these international gatherings, where pledges too often are inadequate, go unfulfilled, or both.

As the world watches Brazil these next couple of weeks, the Bridgetown agenda offers a blueprint — not just for islands, but for the global community’s capacity to rethink finance, justice, and resilience.
