Abstract Large‐scale farming and purposeful sinking of seaweed has been suggested as a marine Carbon Dioxide Removal (mCDR) strategy. Farmed seaweed uptakes dissolved inorganic carbon (DIC) from the mixed layer, resulting in a CO2 deficit that causes an influx of atmospheric CO2 into the surface ocean.

A harmonized LCA and TEA framework evaluates 19 bioenergy pathways, quantifying carbon intensity (CI), minimum fuel selling price (MFSP), and marginal abatement cost (MAC). CCS reduces CI to net‐negative values and lowers MAC by up to 64%, with bioelectricity achieving the lowest MAC and liquid biofuels critical for hard‐to‐abate sectors.

Electrochemical CO2RR is a key technology for converting CO2 into chemicals, but there remains a gap between “laboratory science” and “engineering practice” in current research. This review establishes a multi‐scale research framework, encompassing atomic‐level characterization, microenvironment regulation, external field‐assisted optimization, and AI ...

Equity in allocating carbon dioxide removal quotas
The first nationally determined contributions to the Paris Agreement include no mention of the carbon dioxide removal (CDR) necessary to reach the Paris targets, leaving open the question of how and by whom CDR will be delivered.

Methane Emissions From Flame Curtain Pyrolysis (Kon‐Tiki)
Flame curtain pyrolysis enables decentralized biochar production, but its net climate benefit depends on the magnitude of methane emissions caused during production. Methane emissions were below 5 g CH4 kg−1 biochar for dry feedstocks but increased for moist feedstocks. Pyrolysis emitted less methane than open burning of wheat straw. ABSTRACT Pyrogenic

Rethinking carbon dioxide removal: a justice-centred analysis of CDR perspectives research
This study reviews 177 carbon dioxide removal (CDR) perspectives studies published between 2002 and 2025 through a justice-centred lens. Focusing on who is included, who produces the research, what questions are asked, and what methods are used, we show that: perspectives research remains dominated by researchers and participants in the Global North ...

Existing studies indicate that future global carbon dioxide (CO2) removal (CDR) efforts could largely be concentrated in Asia. However, there is limited understanding of how individual Asian countries and regions will respond to varying and uncertain ...

The U.S. Carbon Cycle Science Program (USCCSP) and the North American Carbon Program (NACP), as connectors and conveners of the U.S. carbon cycle expert community, hosted a workshop in February 2023 to help develop the foundation for a national unified Carbon Dioxide Removal (CDR) Measuring, Monitoring, Reporting, and Verification (MMRV) framework ...

SUMMARY Assessing the potential for macroalgae to function as a carbon sink (blue carbon) and nitrogen (N) assimilation is under intensive investigation. The content of elemental carbon (C) and N in macroalgae is the best indicator of their potential; however, with respect to the thallus, C and N content varies in space and time.

Expert opinions regarding the concept of blue carbon in seaweed systems
SUMMARY A collection of expert opinions critically evaluates the role of seaweed in blue carbon strategies for climate change mitigation. While the concept of fast‐growing seaweed to capture atmospheric carbon is appealing, the experts largely agree that its potential for direct, long‐term carbon sequestration is currently overstated and faces ...
