This article explains how mangroves, seagrass meadows, and salt marshes serve as highly effective blue carbon ecosystems. It examines their ability to store and sequester carbon, reduce greenhouse gas emissions, and support climate mitigation. The article also highlights the need to conserve and restore coastal wetlands worldwide.

Overview

Climate change requires a diverse portfolio of solutions, and blue carbon ecosystems are among the most effective natural tools available for reducing greenhouse gases. This article highlights the critical role of coastal wetlands, including mangrove forests, seagrass meadows, and salt marshes, in capturing, storing, and sequestering carbon over long periods of time. Although these habitats occupy a relatively small portion of the planet, they are among the most productive ecosystems on Earth and store vast amounts of carbon in deep, waterlogged soils. The article explains how the loss and conversion of coastal wetlands release significant amounts of stored carbon into the atmosphere, contributing to climate change, while their protection and restoration provide substantial climate mitigation benefits. Coastal wetlands also actively remove carbon dioxide from the atmosphere and lock it away in soils for centuries or even millennia. As global wetland losses continue, the article emphasizes the urgent need to conserve existing habitats and restore degraded coastal landscapes. Integrating blue carbon into climate policies, conservation strategies, and restoration initiatives can deliver meaningful emissions reductions while providing valuable ecosystem benefits for communities and coastlines worldwide.
