Blue carbon credits from coastal ecosystems like mangroves and seagrass meadows are emerging as a premium asset class in voluntary carbon markets. Unlike forestry offsets, these wetlands sequester carbon for centuries and can store more carbon per hectare. In 2023, mangrove restoration credits averaged $26 per metric ton of CO2, far above the broader market average of $6.63 per ton. Projects like Pakistan's Delta Blue Carbon initiative have restored 80,000 hectares and created public-private partnership models that could scale globally. But the market faces real risks. High upfront costs and rigorous verification requirements mean that poorly measured credits could lose value quickly. Community ownership is also critical: projects that fail to involve local populations risk social and carbon failure. As voluntary carbon markets grow, the tension between financial efficiency and ecological integrity will determine whether blue carbon credits deliver real climate impact or become another speculative bubble.
