The Saltmarsh Code is a voluntary standard enabling the verification and sale of carbon sequestered through saltmarsh restoration. Saltmarsh carbon can be sold to buyers seeking to voluntarily compensate for their emissions, generating additional revenues to accelerate saltmarsh restoration and deliver other social and environmental benefits, such as biodiversity gains, flood alleviation, and nutrient remediation. The […]

The UK has become the first nation to map and estimate the amount of carbon stored in its seabed habitats, including in Marine Protected Areas (MPAs). The Blue Carbon Mapping Project, completed by the Scottish Association for Marine Science (SAMS) on behalf of WWF, The Wildlife Trusts and the RSPB, reveals that 244 million tonnes […]

Limited understanding of basic ocean processes is hindering progress in marine carbon dioxide removal, with the on-going commercialisation of some approaches “premature and misguided”, say a group of international scientists. In a new paper researchers review the climatic effectiveness of four ‘nature-based’ techniques using marine biological processes. These involve shellfish cultivation, seaweed farming, coastal blue […]

A new study by the Helmholtz-Zentrum Hereon models the influence of bottom trawls on sedimentary carbon in the North Sea. The researchers state that fishing trawls cause significant CO2 emissions as they stir up the carbon bound in the seabed and release it again. They also believe it is clear that they drastically affect ecosystems […]

The UK’s saltmarshes are under threat from climate change, coastal erosion, and sea-level rise, according to a new study led by the University of St Andrews and the University of York. Carbon Accumulation Occupying more than 450km² of the UK coastline, saltmarshes capture and store large quantities of carbon, which makes them one of the […]

A new suite of reports has been released which examine Blue Carbon sequestration in restored saltmarsh sites across England. There is growing interest in restoration and creation of coastal wetland habitats from both a biodiversity and blue carbon perspective. Areas of interest for understanding the carbon offsetting potential and natural capital benefits include: Evaluating carbon […]
