Development of VCS methodology for tidal wetlands restoration

Silvestrum has been the lead author of the Methodology for Tidal Wetland and Seagrass Restoration (VM0033) just approved by the Verified Carbon Standard.

This new and innovative methodology provides accounting procedures for greenhouse gas reductions in the restoration of tidal wetlands (salt marsh, mangroves and seagrass).

Coastal wetlands sequester and store significant amounts of carbon in their vegetation and soils (referred to as “blue carbon”). Healthy coastal habitats increase resilience to storms and mitigate for the effects of climate change, in addition to numerous other ecosystem benefits.

Methodology development was led by Restore America’s Estuaries and Silvestrum, with lead financial support from the National Estuarine Research Reserve System Science Collaborative (under the Waquoit Bay NERR Bringing Wetlands to Market: Nitrogen and Coastal Blue Carbon Project). The National Oceanic and Atmospheric Administration’s Office of Habitat ConservationThe Ocean FoundationThe Curtis and Edith Munson Foundation, and KBR all provided additional support.

Methodology authors include Dr. Igino Emmer, Silvestrum; Dr. Brian Needelman, University of Maryland; Steve Emmett-Mattox, Restore America’s Estuaries; Dr. Steve Crooks, Environmental Science Associates; Dr. Pat Megonigal, Smithsonian Environmental Research Center; Doug Myers, Chesapeake Bay Foundation; Matthew Oreska, University of Virginia; Dr. Karen McGlathery, University of Virginia; and David Shoch, Terracarbon.

Silvestrum has been the lead author of various other protocols, including the Methodology for Improved Forest Management: Conversion of Low Productive to High Productive Forest (VM0005), various modules of the REDD+ Modular Methodology (VM0007), and CDM methodology Afforestation and reforestation of degraded mangrove habitats Version 3.0 (AR-AM0014).


In association with methodology VM0033, to assist those considering developing a coastal wetland restoration project for carbon credit, Restore America’s Estuaries and Silvestrum have developed a manual to help coastal restoration projects access carbon finance:

Coastal Blue Carbon in Practice: A Manual for Using the VCS Methodology for Tidal Wetland and Seagrass Restoration.

This manual walks project developers through the process of blue carbon project planning. Coastal Blue Carbon in Practice covers the main phases of carbon project implementation: feasibility and site selection, documentation, registration, implementation, and carbon asset management. The practice manual also includes how to address issues such as sea-level rise and other risks, and considerations for applying a grouped project approach to reduce cost.
