Coastal wetlands capture and bury carbon at high rates. This carbon is called blue carbon. A valuable service that healthy restored wetlands provide is trapping carbon that might otherwise be released to the atmosphere as carbon dioxide. In coastal environments, restoring wetlands can reduce the emissions of other potent greenhouse gasses. With assistance from national wetland experts and funding from our Executive Office of Energy and Environmental Affairs, the Division of Ecological Restoration (DER) has co-created a simple methodology for quantifying the GHG emission of restored aquatic ecosystems, the Blue Carbon Calculator.
