Colombia’s Blue Carbon Initiatives

Thanks to YaleE360 for this brief explanatory note on Blue Carbon Projects from a Colombian perspective:

New Approach to Blue Carbon Projects Underway in Colombia

A mangrove preservation project along Colombia’s Caribbean coast is using a more comprehensive method to calculate how much carbon is stored in coastal and marine ecosystems, potentially boosting global efforts to conserve so-called blue carbon.

Conservation International, working with several partners in Colombia, is spearheading a mangrove protection initiative in Cispatá, Colombia that calculates not only the amount of carbon stored above-water in mangrove trees but also the amount stored underwater in roots and soil. Previous blue carbon projects in mangrove forests have generally counted only carbon stored above water. But since as much as 60 percent of a wetland’s or a mangrove forest’s carbon is sequestered underwater, the new accounting method increases the amount and value of carbon that communities can claim if they protect mangrove forests.

Acre for acre, mangrove forests can store up to 10 times more carbon than terrestrial forests, but in recent decades vast areas of mangroves globally have been lost to aquaculture and development. Conservation International said that as many as 1 billion tons a year of CO2 are released annually from mangrove and other degraded coastal ecosystems, equal to the total amount of CO2 emissions from all of South America in 2019…
