Blue Carbon for Our Planet Act This bill establishes the Interagency Working Group on Coastal Blue Carbon to (1) assess the impediments to the conservation and restoration of coastal blue carbon ecosystems, and (2) establish national conservation and restoration priorities regarding these areas. Coastal blue carbon ecosystems are vegetated coastal habitats and include mangroves, tidal marshes, and other tidal, freshwater, or saltwater wetlands that have the ability to sequester and store carbon.
