The State of the Science for Marine Carbon Dioxide Removal (mCDR) – A Scientific Summary for Policy-Makers [PDF]

Since net zero greenhouse gas emissions targets have become a keystone of climate policy, there has been increasing debate about the need to complement urgently needed emission reductions with active removal of carbon dioxide from the atmosphere (termed ‘carbon dioxide removal’, CDR)This document provides a concise summary of the state of marine CDR ...

Laying waste to the deep: parallel narratives of marine carbon dioxide removal and deep-seabed mining [PDF]

npj Ocean Sustainability
The deep ocean is increasingly featured in climate solution discussions. An emerging narrative suggests that marine carbon dioxide removal (mCDR) is essential to meet global climate targets. The argument made is similar to claims that deep-seabed mining (

Electrochemical ocean iron fertilization and alkalinity enhancement approach toward CO2 sequestration [PDF]

npj Ocean Sustainability
Achieving net-zero emissions by 2050 requires the development of effective negative emission techniques, including ocean-based approaches for CO2 sequestration. However, the implementation and testing of marine CO2 removal (mCDR) techniques such as ocean

The importance of engagement with fisheries, aquaculture, and Indigenous communities in the planning and implementation of marine carbon dioxide removal (mCDR)

ICES Journal of Marine Science
Abstract As climate change continues to increase in severity, the window of time available to achieve climate stabilization decreases. In addition to reducing emissions, climate solutions such as marine carbon dioxide removal (mCDR) are being considered.

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 ...
