Abstract/Summary

This Issues Paper reviews peer-reviewed scientific evidence on the potential to expand carbon finance methodologies under the Verified Carbon Standard (VCS) to encompass Near Shore Seascape Carbon, beyond current ecosystems considered under such mechanisms, i.e., vegetated wetlands. For this assessment, no evidence was therefore reviewed on tidal wetlands, seagrasses, and mangrove ecosystems, for which carbon offset methodologies already exist. Management of blue carbon ecosystems has become an area of extreme interest in the context of providing nature-based solutions, or nature-inclusive designs for environmental management, that may help to deliver climate change mitigation. Carbon market methodologies for such defined management activities outline procedures that projects must follow to deliver GHG emission reductions or removals that are real, measurable, additional, permanent (>100 years), independently verified, and conservatively estimated. These methodologies must be rooted in scientific understanding of the global carbon cycle so that projects can develop high quality and credible carbon offsets for the carbon markets. Such carbon projects are coming online for tidal wetlands, particularly mangroves. A lack of scientific consensus and in many cases data gaps, amongst other challenges, have prevented the inclusion of other marine ecosystems under carbon market mechanisms thus far. This has limited the ability to harness private finance to further support the growth of ocean carbon conservation. In recent years, science has advanced at pace.
