Carbon Credits for Coastal Wetland Restoration.

Coastal wetlands have high carbon sequestration rates due to high net primary productivity, low decomposition rates, and vertical accretion under sea level rise. Coastal wetland restorations may be eligible for carbon credits under various regional and national programs. The northeast Regional Greenhouse Gas Initiative is currently considering the inclusion of salt marsh restoration and conservation as an eligible offset. In this talk I will discuss the potential for carbon sequestration through coastal wetland restoration in the United States, the value that these carbon credits may generate, and the scientific and policy challenges associated with obtaining carbon credits through coastal wetland restoration. These challenges include land ownership issues (federal, state, private), accounting for losses and protection of existing wetlands, long-term carbon fate, verification demands, baseline carbon accounting, allochthonous carbon, and carbon usage during restoration. Carbon sequestration is one of many important ecosystem services provided through wetland restoration and may be a source of initial and long-term income for restoration projects.
