Summary

When most of us think about using nature to remove carbon dioxide from the air, we think of trees. Yet blue carbon, a new name for storing carbon dioxide in coastal and marine ecosystems where it can no longer trap heat in our atmosphere, may have even greater potential. Salt marshes and mangroves have carbon-capturing capacity that may surpass that of terrestrial forests. Seagrasses, for example, currently cover less than 0.2% of the ocean floor, but store about 10% of the carbon buried in the oceans each year. How can natural, ocean-based solutions benefit both the planet and the people who live in and depend on coastal ecosystems?  Guests:  Ralph Chami, Assistant Director, Western Hemisphere Division, Institute for Capacity Development, IMF Emily Pidgeon, Vice President, Ocean Science And Innovation, Conservation International Irina Fedorenko-Aula, Founder, Co-CEO, Vlinder Isabella Masinde, CEO, Umita For show notes and related links, visit our website.

Through the use of carbon markets, it could be a tool for stabilizing the climate that sustains our lives and economy.

If you were to use the average price of carbon, which is about $60, the total value of carbon services of seagrasses over $2 trillion. Many of the opportunities for blue carbon markets are located in developing countries along the equator.
