Coastal Blue Carbon Approaches for Carbon Dioxide Removal and Reliable Sequestration: Proceedings of a Workshop -- in Brief (2017)Board on Atmospheric Sciences and Climate
Coastal environments provide many valuable ecosystem services. Their role as carbon sinks has been a topic of exploration to evaluate the potential for the restoration and management of coastal habitats as a viable carbon dioxide removal (CDR) approach. To explore the state of knowledge, technical research needs, costs, co-benefits, and societal and governance constraints of CDR in coastal ecosystems (often termed coastal blue carbon), the Committee on Developing a Research Agenda for Carbon Dioxide Removal and Sequestration convened its first workshop on July 26, 2017, in Woods Hole, Massachusetts. Invited speakers described their relevant work in order to provide the committee with an overview of the state of knowledge and research needs related to understanding carbon capacity and flux in coastal systems, the processes driving sustainability of coastal wetland carbon storage in the future, potential incentives for coastal blue carbon, and policy and governance challenges. The workshop was preceded by an introductory webinar on July 19, 2017, where invited speakers provided an overview of the ecosystems under consideration for coastal carbon removal and sequestration, as well as the costs and other considerations of restoring them. This publication summarizes the presentations from both the webinar and workshop.
