High-Quality Blue Carbon Principles and Guidance

A Triple-Benefit Investment for People, Nature, and Climate

A Global Vision for High-Quality Blue Carbon

The World Economic Forum (WEF) Friends of Ocean Action, the Ocean Risk and Resilience Action Alliance (ORRAA), Salesforce, The Nature Conservancy, and Conservation International with the support of Meridian Institute developed the High-Quality Blue Carbon Market Principles and Guidance. They clearly describe what ‘high quality’ means for blue carbon projects and credits, to foster investments that have triple benefits for people, nature, and climate.

The Principles and Guidance provide a consistent and understandable approach to guide the development and management of blue carbon projects that are equitable, fair, and credible.

The High-Quality Blue Carbon Principles and Guidance Launched at COP27

The High-Quality Blue Carbon Principles and Guidance: A Triple-Benefit Investment for People, Nature, and Climate was formally launched on November 12, 2022 at COP27 of the UNFCCC. The panel was part of the We Mean Business Coalition Pavilion and the discussion featured Salesforce, Blue Ventures, and Silvera and was moderated by World Economic Forum’s 1 Trillion Trees. This session focused on corporate pledges in support of nature-based solutions and how appropriate interventions can restore degraded ecosystems to provide benefits beyond carbon.

How did we arrive at the Principles and Guidance?

The Principles and Guidance were directly informed by a global consultative process that consolidated existing knowledge and best practices to build a shared vision for achieving high-quality blue carbon projects and credits for all stakeholders. Stakeholder engagement brought together thought leadership by scientists, developers, investors, buyers, and certifiers to produce a set of clear, concise principles and guidance that characterize high-quality blue carbon projects and credits.

About the High-Quality Blue Carbon Principles and Guidance

The High-Quality Blue Carbon Principles and Guidance: A Triple-Benefit Investment for People, Nature, and Climate describe what constitutes high-quality, marine conservation best practices, with the goal of preserving and restoring blue carbon ecosystems. The term 'Blue carbon' in this document refers to the intertidal ecosystems that capture and store carbon that currently have methodologies for verification and certification by an authorized certifying body. Mangrove forests, seagrass meadows, and tidal marshes are the three ecosystems highlighted in this document, however we recognize additional intertidal systems are being developed for blue carbon credits; the addition of certifications for other coastal ecosystems should also strive to meet the qualities of 'high quality' that are provided in this guidance.

Quotes from Featured Supporters

Benioff Ocean Science Laboratory

“Blue carbon represents a promising opportunity to fight climate change and promote ocean health. The High-Quality Blue Carbon Principles and Guidance fill a key niche in helping blue carbon leaders to create more impact in this new domain.”



“We are thrilled to participate in this vital effort articulating core principles and guidance for quality blue carbon.”


Fair Carbon

“Fair Carbon has been supporting this work since its inception and we are delighted to see the High-Quality Blue Carbon Principles and Guidance shared at COP27. The ethical approach outlined in these principles is integral to the project design support we provide and reflects our core messaging. It is our hope that this document informs and elevates due diligence procedures and best practice amongst credit buyers, promotes recognition of the higher production cost and value of high-quality blue carbon credits, and incentivizes developers to implement projects which are inclusive, fair, and scientifically credible”.



“We at goodcarbon support the implementation of High-Quality Blue Carbon Principles and Guidance. The principles provide direction for all VCM participants on how to ensure real impact generation for climate, nature and people. They also show the challenges in the blue carbon space that can only be overcome if we work together. goodcarbon embraces these principles since they are in line with our mission and will contribute to their implementation when working together with project owners as well as with investors and buyers.”



“The High-Quality Blue Carbon Principles and Guidance allow companies like Iberostar to feel confident in supporting projects that not only sequester carbon but prioritize biodiversity and communities. At Iberostar, we have outlined a commitment to have up to 500,000 metric tonnes of carbon sequestered annually through protecting and restoring nature by 2030. This guidance helps us better design projects that ensure high value carbon that conserve valuable ecosystems for the tourism sector while also empowering communities and creating resilience through transparency and integrity.”



“The carbon market needs integrity and clear, positive impact – on carbon and beyond. IUCN is excited to work within its programmes such as the Blue Carbon Accelerator Fund (BCAF), to apply these principles with project developers and communities on the ground.”

Dorothee Herr, Manager, Oceans and Climate Change



“KlimatelinK’s Ocean and Blue Carbon global community is dedicated to create and expand high quality blue carbon projects by connecting project practitioners to the relevant stakeholders that will help them save time and money through tailored trustworthy connections.”



“Blue carbon ecosystems are featured across the beloved shows on the Netflix platform and are critical for local livelihoods, biodiversity, climate resilience and carbon storage and removal. Netflix is proud to support high-quality blue carbon projects through our Net Zero + Nature program and welcomes this guidance to support and accelerate enhanced investment in these critical natural areas.”

Alexia Kelly, Director, Net Zero + Nature



“As the developers of technology to allow for accurate monitoring and accounting of carbon stock in seagrass meadows, we believe strongly in the importance of transparent and meticulous carbon accounting practices. To mitigate climate change, we must protect and restore ecosystems rich in carbon, such as coastal areas. They provide critical habitats for high biodiversity, as well as storing vast amounts of carbon. Both of these elements are equally respected in the white paper. In its principles and guidelines, carbon capture is balanced with ecosystem preservation.”

Elisabeth Moore, Communications Manager


Plan Vivo Foundation

“Plan Vivo welcomes these principles to guide investment into projects that put communities at the forefront of nature-based solutions. We believe that empowering and supporting communities is key to long-term success of projects, and we’re pleased that this is being represented as best practice for high-quality blue carbon credits. These principles closely align with Plan Vivo’s core values and reflect the minimum threshold for a Plan Vivo-certified project, and it’s great to see them being adopted to benefit local livelihoods, climate, and nature.”


Silvestrum Climate Associates

“Blue carbon credits provide the opportunity to deliver high-value ecosystem restoration and conservation. The principles and guidance connect a partnership between high-quality projects and high-quality investors.”



“Meeting the challenges of this century requires updating our economic logic and operating system. From an obsolete ‘ego-system’ focused entirely on the well-being of oneself to an eco-system awareness that emphasizes the well-being of the whole.”

Otto Scharmer, MIT Presencing Institute
