1 What is “Coastal Blue Carbon”? A win-win-win for habitat conservation, coastal resilience, and climate mitigation Dr. Ariana Sutton-Grier NOAA Coastal Blue Carbon Team Lead May 21, 2014

2 U.S. Department of Commerce | National Oceanic and Atmospheric Administration | NOAA Fisheries | Page 2 Our Changing Carbon Cycle Black Carbon (human emissions) Blue Carbon (coasts and oceans) Green Carbon (terrestrial biota) Coastal Blue Carbon Coastal habitats: Salt marshes Mangroves Sea Grasses www.noaa.gov www.pmel.noaa.gov/co2/story/Research

3 Locations of Coastal Blue Carbon Coastal blue carbon is almost everywhere Pendleton et al. 2012

4 What do coastal blue carbon habitats look like? Mangroves, Salt Marsh, and Seagrasses

5 Coastal Habitats Sequester Carbon Smaller total area, but much greater sequestration in coastal blue carbon habitats Coastal habitats ~equivalent annual sink to forest systems McLeod et al. 2011. Frontiers in Ecology and Environment

6 Coastal Habitats Store Carbon In coastal habitats, most carbon is stored in sediments and less in biomass Source: Murray, Brian, Linwood Pendleton, W. Aaron Jenkins, and Samantha Sifleet. 2011. Green Payments for Blue Carbon: Economic Incentives for Protecting Threatened Coastal Habitats. Nicholas Institute Report. NI R 11-04. ~ Emissions produced by 214 passenger vehicles per year Boreal

7 Rapid Loss of Coastal Carbon Services From 2004-2009, U.S. coastal watersheds lost wetlands at an average rate of 80,000 acres/year Worldwide, rates of loss range from 0.7 – 7% annually Coastal carbon emissions ~3- 19% those of deforestation annually (Pendleton et al. 2012)

8 Pendleton et al. 2012 PLoSOne Assumes “social cost of carbon” = US$41/ton What is the cost of blue carbon emissions?

10 Pathways for Blue Carbon Services & Conservation U.S. Department of Commerce | National Oceanic and Atmospheric Administration | NOAA Fisheries | Page 10 10 Additional resources through carbon markets for protection and restoration Bottom half in white is dependent on carbon markets. Market Policy Needs: Protocols for GHG accounting Carbon market protocols Science Needs: Estimates of net C storage and sequestration Areal extent of habitats & loss rates Carbon dynamics of habitat disturbance and restoration GOAL: Enhanced Conservation of Coastal Habitats (e.g., salt marsh, sea grass, and mangroves) Improve ability to incorporate carbon services in programs and policies (e.g., mitigation projects, NEPA, UNFCCC) Top half in blue is NOT dependent on carbon markets. NOAA Policy Needs: Identification of policies that should consider coastal carbon Procedures for how to incorporate C services into activities

11 Analysis of Federal Policies We explored: 1.Whether carbon services of ecosystems could be incorporated into the implementation of federal policies? 2.If so, where would carbon services work in implementation?

12 Analysis of carbon services in federal policies National Environmental Policy Act (NEPA) Natural Resources Damage Assessment (NRDA) (part of the Oil Pollution Act) Clean Water Act (CWA) mitigations (404 (d) permits) Coastal Zone Management Act (CZMA) Endangered Species Act (ESA) Water Resources Principles and Guidelines (P&G)

13 Findings Determined: No new regulations needed Coastal carbon could be incorporated into the implementation of all without statutory changes, but is currently not included Incorporation of carbon services in these policies could lead to more habitat conservation seagrassgrow.org Sutton-Grier et al. 2014. Marine Policy & Pendleton & Sutton-Grier et al. 2013. Coastal Management

14 Common Limitations Guidance and procedures for estimating and valuing coastal carbon Capacity and expertise needed to quantify impacts of projects on carbon storage and sequestration Methodologies and tools for measuring and valuing carbon and expertise externally and within Federal agencies

15 NOAA Coastal Blue Carbon Science Activities Waquoit Bay study at the National Estuarine Research Reserve “Bringing Wetlands to Market” Science to support including wetlands in carbon markets to incentivize investment in wetland restoration and preservation

16 NOAA International Coastal Blue Carbon Activities Supported the development of a UNFCCC workshop on blue carbon Lead agency in the Commission on Environmental Cooperation grant (2013-2015) to build a North American community of practice for blue carbon Supported the Global Environment Facility “Blue Forest” ecosystem services project and member of the project steering committee

17 Carbon Market Opportunities Support Restore America’s Estuaries in their study of opportunities for wetland carbon in voluntary carbon markets: Identifying steps (methodology) to make protection and restoration projects eligible for carbon trading Developing landscape assessment of restoration potential of Snohomish estuary Full restoration of tidal and forested wetlands in watershed would result in 4.4 million tons of CO 2 equivalents being sequestered (~annual emissions from 832,000 passenger cars) Developing and conducting regional workshops to discuss coastal blue carbon concepts and opportunities

18 Next Steps Investigate incorporation of coastal blue carbon into federal policies and practices that increase coastal habitat conservation Current NEPA exploration, CEQ GHG Guidance, U.S. GHG inventory process Explore additional opportunities to support Coastal Blue Carbon Science E.g., Sea Grant funding, NERRS, Sentinel Sites, Sanctuaries, LCCs Support and inform the UNFCCC negotiations process

19 Other benefits of blue carbon habitats: Habitat

20 Other benefits of blue carbon habitats: Recreation

21 Other benefits of blue carbon habitats: Storm Protection U.S. coastal wetlands provide $23.2 billion storm protection benefits annually (Constanza et al., 2008)

22 “Protecting the city, before next time” New York Times, Nov. 3, 2012 Creative ecosystem protection ideas for NY Blue carbon habitats, A LOT MORE THAN JUST CARBON SINKS! Interest in “green infrastructure” and “living shorelines” for storm protection
