Marine carbon dioxide removal (mCDR) is an emerging approach to mitigating climate change by removing carbon dioxide (CO2) from the atmosphere and harnessing the ocean’s natural ability to store carbon as it has always done on its own. However, this industry remains nascent, facing challenges in technological maturity, scalability, and understanding long-term environmental impacts.

Having a comprehensive map that diagrams the relationships between all participants involved in mCDR is crucial. It facilitates collaboration and knowledge sharing among researchers, policymakers, industry stakeholders, and environmental organizations. mCDR involves a complex interplay of various disciplines, making interdisciplinary cooperation essential. Additionally, such a map can help streamline regulatory and governance frameworks, ensuring responsible and sustainable implementation.

What’s on the map?

The mCDR Ecosystem Map illustrates both the flow of this emerging industry as well many stakeholders involved in researching, governing, developing, and deploying mCDR solutions. Categories include:

• Monitoring, Reporting, and Verification (MRV)

• mCDR Providers

• Pre-Purchasers

• Accountability (e.g. Carbon Registries)

• Funders

• mCDR Coordinators

Who created the map?

The first version of the map was created Namy Barnett of [C]Worthy, and it is a living document that our team will continually update as the mCDR ecosystem evolves and grows.
