; (4) to assess degraded coastal blue carbon ecosystems and their potential for restoration, including developing scenario modeling to identify vulnerable land areas where management, protection, and restoration efforts should be focused; and (5) produce future predictions of coastal blue carbon ecosystems and carbon sequestration rates in the context of climate change, environmental stressors, and human stressors. 4. Restoration and protections for existing coastal blue carbon ecosystems (a) In general The Administrator shall— (1) lead the Interagency Working Group in implementing the strategic plan under section 2(e)(2); (2) coordinate monitoring and research efforts among Federal agencies in cooperation with State, local, and Tribal government and international partners and nongovernmental organizations; (3) assess the feasibility and potential of establishing a national goal of conserving at least 30 percent of the ocean and coastal blue carbon ecosystems within the territory of the United States by 2030, including the effects of climate change and sea level rise on such goal, and as appropriate setting targets for restoration of degraded coastal blue carbon ecosystems; (4) in coordination with the Interagency Working Group and as informed by the report under section 2(e) on current Federal expenditures on coastal blue carbon ecosystem restoration, identify— (A) national coastal blue carbon ecosystem protection and restoration priorities that would produce the highest rate of carbon sequestration and greatest ecosystem benefits such as flood protection, soil and beach retention, erosion reduction, biodiversity, water purification, and nutrient cycling in the context of other environmental stressors and climate change; and (B) ways to improve coordination and to prevent unnecessary duplication of effort among Federal agencies and departments with respect to research on coastal blue carbon ecosystems through existing and new coastal management networks
