An Australian blue carbon method to estimate climate change mitigation benefits of coastal wetland restoration

Abstract: Restoration of coastal wetlands has the potential to deliver both climate change mitigation, called blue carbon, and adaptation benefits to coastal communities, as well as supporting biodiversity and providing additional ecosystem services. Valuing carbon sequestration may incentivize restoration projects; however, it requires development of rigorous methods for quantifying blue carbon sequestered during coastal wetland restoration. We describe the development of a blue carbon accounting model (BlueCAM) used w… Show more

“…Globally, mangroves along with other marine and coastal habitats, are increasingly being recognised as a nature-based solutions to climate change-as an opportunity to protect our coastlines from sea level rise, and store and sequester carbon from our atmosphere [5,41,42]. Employing strategies that protect these habitats is vital for the ecosystem services they provide.…”

“…A restoration activity which causes a transition from one ecosystem or land use to another is also likely to generate emissions associated with that transition when the original plants die (Lovelock et al, 2022). Typically, this should be small relative to the amount of sequestration for projects to be feasible.…”

“…The criteria of real and independently verified generated some challenges due to difficulties in measuring carbon abatement in coastal wetlands. This issue was overcome by a decision to use a modeled approach, whereby abatement can be estimated with a high degree of accuracy from measurement of the area of blue carbon vegetation types that develop within the area of tidal introduction (Lovelock et al 2022a(Lovelock et al , 2022b. The Blue-CAM model developed for the methodology is based on empirical data and robust in its design, and overcomes the potential problem of high costs of measuring carbon abatement outweighing the possible economic value of carbon credits that may be generated (Köhl et al 2020).…”

“…Although Australia's Blue Carbon methodology is still in its infancy, the experience in its development and drafting offers Restoration Ecology September 2023 valuable lessons for coastal wetland restoration projects in other sectors and other jurisdictions, in terms of the science underpinning it (Lovelock et al 2022b), the various mechanisms employed to clear the legal hurdles, and the process of developing the methodology itself. In particular, the methodology development process drew heavily upon the expertise of science and legal experts, and the responsible government agency convened numerous expert workshops over several years (Minister for Industry, Energy and Emissions Reduction 2022), obtained expert reports (e.g.…”
