Perspectives and challenges of marine carbon dioxide removal [PDF]

Frontiers in Climate
The Paris Agreement to limit global warming to well below 2°C requires drastic reductions in greenhouse gas emissions and the balancing of any remaining emissions by carbon dioxide removal (CDR). Due to uncertainties about the potential and durability of

Navigating Potential Hype and Opportunity in Governing Marine Carbon Removal [PDF]

Frontiers in Climate, 2021
As the technical and political challenges of land-based carbon dioxide removal (CDR) approaches become more apparent, the oceans may be the new “blue” frontier for carbon drawdown strategies in climate governance.

Hugging the Shore: Tackling Marine Carbon Dioxide Removal as a Local Governance Problem [PDF]

Frontiers in Climate, 2021
This Perspective explores the local governance of ocean-based carbon dioxide removal (CDR). Proposals to enhance the ability of oceans and marine ecosystems to absorb atmospheric CO2 are often discussed as examples of “geoengineering,” but this framing ...

Potential impacts of marine carbon dioxide removal on ocean oxygen [PDF]

Environmental Research Letters
Global warming is a main cause for current ocean deoxygenation. A deployment of marine carbon dioxide removal (CDR) for mitigating global warming could therefore also be viewed as a measure for mitigating ocean deoxygenation if, and only if, the ...

Seawater carbonate chemistry based carbon dioxide removal: towards commonly agreed principles for carbon monitoring, reporting, and verification [PDF]

Frontiers in Climate
Carbon Dioxide Removal (CDR) from the atmosphere is unavoidable if we are to meet the Paris Agreement’s goal of limiting global warming to 1.5°C, and almost certainly required to limit warming to 2°C.

A holistic assessment framework for marine carbon dioxide removal options

Environmental Research Letters
Marine carbon dioxide removal (mCDR) options could potentially play an important role in future CDR policy portfolios. They include, for example, ocean alkalinity enhancement, blue carbon projects such as mangrove cultivation, as well as sub-seabed ...

Early Career Recommendations for the Equitable Growth of a Marine Carbon Dioxide Removal Sector [PDF]

Perspectives of Earth and Space Scientists
In addition to steep carbon emission reductions, all modeled pathways to reach global climate goals require carbon removal. Marine carbon dioxide removal has the potential to play a large role in drawing down legacy anthropogenic emissions due to the ...

Impact of marine carbon removal on atmospheric CO2

Environmental Research Letters
A computer simulation of Earth’s climate is used to study if marine carbon removal will lead to a reduced atmospheric carbon dioxide concentration, and if there are potential secondary impacts on marine life and chemistry.

Counting (on) blue carbon—Challenges and ways forward for carbon accounting of ecosystem-based carbon removal in marine environments [PDF]

PLOS Climate, 2023
The latest IPCC assessment report highlights once more the need for negative emissions via carbon dioxide removal (CDR) measures to reach ambitious mitigation goals.
