Barbados Prime Minister Mia Mottley is intensifying her call for global reforms to address climate change and sovereign debt, highlighting the disproportionate burden faced by poorer nations. Mottley, who became the country’s first female prime minister in 2018 and the first prime minister to serve after Barbados transitioned to a republic in 2021, has been a prominent voice in advocating for financial restructuring to support vulnerable countries.

In 2022, Mottley introduced the Bridgetown Initiative, a comprehensive proposal aimed at overhauling the global debt system. The plan urges wealthier countries to increase their financial contributions toward climate adaptation and mitigation, arguing that poorer nations, which have contributed minimally to global carbon emissions, are enduring the most severe climate impacts. She has framed the issue as urgent, warning at the 2024 United Nations Climate Change Conference (COP29) in Baku that the world is “hurtling towards catastrophe” amidst rising extreme weather events.

A central concern in Mottley’s advocacy is the heavy debt burden carried by developing countries, which often face repayment rates between 12 and 14 percent—significantly higher than the 1 to 4 percent typical in wealthier nations. This debt strain limits these countries’ ability to recover from climate disasters such as floods, hurricanes, and droughts. Mottley has called for interest rates on these debts to be paused or canceled, drawing parallels to debt relief provided after World War II. She warns that without such measures, continued debt servicing could be catastrophic, potentially a “death sentence” for nations like Barbados.

Barbados has taken practical steps aligned with these proposals. In December 2024, the island nation implemented its first “debt-for-climate resilience swap,” a financial arrangement that converted expensive foreign debt into more affordable financing. This restructuring generated $125 million in savings, which have been allocated toward a water and sewage infrastructure project designed to bolster climate resilience. Barbados’ Bridgetown Initiative was recognized as a finalist for the Earthshot Prize in 2025, an environmental award celebrating innovative solutions to global challenges.

At the 2025 United Nations General Assembly, Mottley further pressed world leaders to mobilize $1.3 trillion annually by 2035 to support the green transition in developing countries. Her ongoing efforts emphasize the intersection of climate vulnerability and economic inequality, underscoring the need for systemic change in international financial governance to achieve equitable climate action.
