Parameterizing air–sea CO2 transfer in a macroalgal habitat and assessing its role in marine carbon dioxide removal accounting

Limnology and Oceanography Letters, Volume 11, Issue 4, July 2026.
Abstract Accurately quantifying air–sea CO2 exchange remains a central challenge for the measurement, reporting, and verification (MRV) of marine carbon dioxide removal. I apply direct eddy covariance measurements of CO2 fluxes at a macroalgae‐dominated coast to compile the first gas transfer velocity (k660) parameterization for such a habitat.

Soil sample timing and depth effect on soil health assessment in Mid‐South US row‐crop production systems

Soil Science Society of America Journal, Volume 90, Issue 4, July/August 2026.
Abstract Spatial and seasonal variability in soil properties influences soil analysis results, but their impact on soil health assessment has not been well investigated. We evaluated how soil health indicators and scores were affected by soil sampling time (spring, summer, fall, and winter) and depth (0–5, 5–10, and 10–15 cm).

Carbon accounting for carbon dioxide removal [PDF]

Carbon dioxide removal (CDR) technologies are essential to address climate change and serve to compensate for legacy and hard-to-abate greenhouse gas emissions. Although near-term emissions reductions should be the priority, development and deployment of

Life Cycle Assessment applied to Carbon Dioxide Removal processes: a literature review [PDF]

, 2022
In addition to sharp emission reductions, it is necessary to remove carbon dioxide (CO2) from the atmosphere through Carbon Dioxide Removal (CDR) processes, also called Negative Emission Technologies (NET), for limiting global warming according to the

Reconceptualising seaweed cultivation in China: climate law and policy implications

Carbon Management
The Chinese goal to reach carbon peak by 2030 and achieve carbon neutrality by 2060 (the “30/60” dual carbon goal) will require a swift and dramatic reduction in greenhouse gas emissions.

Key messages for the ethical governance of Carbon Dioxide Removal (CDR)

, 2023
TechEthos, in its policy brief, delves into the regulatory challenges within EU laws and policies surrounding Carbon Dioxide Removal (CDR). Addressed to European Union (EU) policymakers and officials engaged in climate-related initiatives, the recommendations are crafted to ensure ethical, rights-based, and sustainable development of CDR.To ensure it ...

Measurements in Geochemical Carbon Dioxide Removal [PDF]

, 2023
Geochemical carbon dioxide removal (CDR) technologies capture and store carbon dioxide (CO2) from the atmosphere using alkaline materials that are rich in calcium (Ca) and magnesium (Mg).

The Evidence for Linearly Scaling Ocean Gas Exchange With Sea Ice Needs Strengthening

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 7, July 2026.
Abstract Polar oceans are critical components of the oceanic uptake of atmospheric carbon dioxide. Estimates of this uptake across the air‐sea interface require parameterizations of gas transfer velocity that account for variable sea ice concentrations.

Expert elicitation on agricultural enhanced weathering reveals carbon dioxide removal potential and uncertainties in loss pathways

Communications Earth & Environment
Enhanced weathering in agriculture is a potential gigatonne-scale carbon dioxide removal (CDR) pathway, but its potential remains difficult to constrain. We used a formal expert elicitation process to estimate CDR potential and efficiency, uncertainties,

Methane Emissions Offsetting With Temporary Carbon Sinks

GCB Bioenergy, Volume 18, Issue 7, July 2026.
A time‐explicit framework based on atmospheric impulse–response functions quantifies the CO2 removal required to offset methane warming within 20 years. Constant, variable, and increasing carbon sinks each demand different removal masses, demonstrating that sink timing—not just permanence—determines the climate value of temporary carbon storage ...
