Blue carbon

19 January 2022

A blue carbon method will create opportunities to store carbon through restoring mangroves and tidal marshes and reduce methane and nitrous oxide emissions through reintroduction of tidal flows.

The blue carbon method was made by the Minister in January 2022.

For more information on the method visit the tidal restoration of blue carbon ecosystems method page.

For information on public consultation and consideration of the method by the Emissions Reduction Assurance Committee (ERAC), visit the blue carbon method page on the Department of Industry, Science, Energy and Resources’ consultation hub.

Issues Register

IssueResponse
Permitting seeding and planting for blue carbon projects.The blue carbon method allows environmental coastal wetland plantings where the plants or propagules used are native to the local area and a mix of species is used that reflects the typical structure and composition of local native vegetation communities.
Whether existing regulatory and approval regimes are sufficient to manage potential adverse impacts from the reintroduction of tidal flows.The agency undertook an assessment of Commonwealth, State and Territory regulatory frameworks that manage potential adverse impacts from the reintroduction of tidal flows. The method contains provisions to manage outstanding risks such as the requirements to provide an acid sulfate soils management plan and mosquito management plan.
Investigating what low-cost options are available to evidence the modelled abatement figures and that regeneration of vegetated coastal ecosystems is occurring.The agency has worked with blue carbon experts to develop the Blue Carbon Accounting Model (BlueCAM) to model net abatement from blue carbon projects.
​Specifying the mapping and hydrological modelling requirements for blue carbon projects.
The agency has prepared a Supplement to the blue carbon method that outlines the mapping and hydrological mapping requirements for blue carbon projects.
