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

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.

Efficacy of individual and combined terrestrial and marine carbon dioxide removal

Environmental Research Letters
Limiting global temperature rise below 2 °C requires significant reduction in greenhouse gas emissions and large-scale carbon dioxide removal (CDR). This study assesses the CO _2 sequestration and efficacy of two CDR approaches, bioenergy with carbon ...

Removal of dissolved inorganic carbon from seawater for climate mitigation: potential marine ecosystem impacts

Frontiers in Climate
Electrochemical technology can be used to remove inorganic carbon from seawater and facilitate the removal of carbon dioxide (CO2) from the atmosphere. Electrochemical ‘Direct Ocean Carbon Capture and Storage’ (DOCCS) is a marine carbon dioxide removal ...

Regional ocean biogeochemical modeling challenges for predicting the effectiveness of marine carbon dioxide removal

Frontiers in Climate
Effectively scaling diverse marine carbon dioxide removal (mCDR) technologies from pilot-scale demonstrations to industrial-scale deployments requires a quantitative understanding of how much additional carbon a given deployment will sequester compared ...

Marine carbon dioxide removal by alkalinization should no longer be overlooked

Environmental Research Letters
To achieve the Paris climate target, deep emissions reductions have to be complemented with carbon dioxide removal (CDR). However, a portfolio of CDR options is necessary to reduce risks and potential negative side effects.

The potential of the BBNJ clearing house mechanism to enhance knowledge pluralism in marine carbon dioxide removal assessment

Frontiers in Climate
As the global community intensifies efforts to achieve net-zero greenhouse gas emissions, active carbon dioxide removal (CDR) is being planned alongside emission reductions.

Is marine carbon dioxide removal right for Aotearoa New Zealand?

New Zealand Journal of Marine and Freshwater Research
ABSTRACT Marine carbon sinks are identified as potential nature‐based solutions in the second Emissions Reduction Plan released in December 2024. Although the scientific basis for marine carbon dioxide removal (mCDR) is still being established, activities are nonetheless advancing internationally and there is increasing domestic ...

Monitoring marine carbon dioxide removal: quantitative analysis of indicators for carbon removed and environmental side-effects

Environmental Research Letters
Marine carbon dioxide removal (mCDR) implementations can potentially remove 1–15 Gt CO _2 yr ^−1 , which encompasses the minimum requirement removal of CDR in 2050 to limit warming below 2 °C by 2100.
