Scientists have demonstrated that carbon sequestered in coastal wetlands is significant and offers a newly recognized climate mitigation benefit. The restoration of coastal wetlands can jump-start carbon sequestration, reduce methane emissions and help governments and other entities achieve their climate change mitigation and adaptation targets. The carbon sequestered in coastal wetlands (sea grasses, mangroves and salt marshes) is commonly called "blue carbon". Massachusetts is a nationwide leader in wetland restoration having restored approximately 2,000 acres of coastal wetlands and the state's Division of Ecological Restoration, together with its partners, have thousands of acres of wetland restoration in planning and design, making it potentially a prime state for developing a blue carbon market. The presenter will explore the role of blue carbon in assisting Massachusetts meet its climate change targets and how to calculate, using the best available science, the green house gas budget (methane and carbon) for a wetland or river restoration project using the new "Blue Carbon Calculator". The "Blue Carbon Calculator" is an innovative tool developed by industry experts for estimating an important ecosystem service associated with ecological restoration.
