Mia Mottley, prime minister of Barbados, speaks at the COP27 U.N. Climate Summit, Nov. 8, 2022, in Sharm el-Sheikh, Egypt. The Barbados plan, dubbed the Bridgetown Initiative, could be a pathway to unlocking large sums of money from rich countries, which have contributed most to greenhouse gas emissions. Mottley first unveiled her idea at the COP26 meeting a year ago in Glasgow, Scotland, where she delivered a powerful speech and sketched out a rough plan to come up with new and innovative forms of climate finance.
