Blue carbon refers to the remarkable capacity of coastal ecosystems to store carbon dioxide. Coastal plants sequester carbon up to 100 times faster than terrestrial forests and store it for thousands of years.
Blue carbon strategies restore and rebuild seagrass meadows, salt marshes, and kelp forests to increase storage of carbon. Restoring coastal ecosystems also enhances resilience to climate change hazards such as coastal flooding. In addition, restoring wetlands sooner rather than later will lock in carbon stored in wetland plants and soils under rising seas.

Coastal Blue Carbon Opportunity Assessment for Snohomish Estuary: The Climate Benefits of Estuary Restoration
This study concludes that currently planned and in-construction restoration projects in the Snohomish estuary will result in at least 2.55 million tons of CO2 sequestered from the atmosphere over the next 100 years.
