Mangroves Store 4x More Carbon Than Rainforests: Why Blue Carbon Matters

Mangrove forests cover less than 1% of Earth's surface but punch far above their weight in carbon storage. Research from The University of Queensland shows these coastal ecosystems can sequester roughly four times more carbon per hectare than tropical rainforests. That makes them a critical natural climate solution, especially for tropical nations with long coastlines. Beyond carbon, mangroves protect shorelines from storm surges and provide nursery habitats for fish and marine life. As World Mangrove Day approaches, scientists are pushing for stronger protection and restoration efforts. The challenge is that mangroves are still being cleared for aquaculture and development in many regions, releasing stored carbon back into the atmosphere. For carbon markets, blue carbon projects offer a high-impact opportunity. But verifying permanence in tidal zones is harder than for terrestrial forests. Anyone looking at offsets should check how projects handle storm damage and sea level rise risks.
