(2022). Biochar as a carbon dioxide removal strategy in integrated long-run climate scenarios.Synopsis: Limiting global warming to under 2°C requires stringent mitigation and carbon dioxide removals (CDR). Biochar, a low-cost soil amendment, shows promise. Using a global model, biochar could sequester up to 2.8 GtCO2 annually, reducing temperature rises by 0.5-1.8% by 2100. Its effectiveness depends on crop yield gains, application rates, and competition with other CDR measures, proving competitive, especially at lower carbon prices.
McDermott, F., Bryson, M., Magee, R., & van Acken, D. (2024). Enhanced weathering for CO2 removal using carbonate-rich crushed returned concrete; a pilot study from SE Ireland. Applied Geochemistry, 106056.Synopsis: A 1.21-ha study in SE Ireland explored using 7.5 tonnes/ha of crushed returned concrete (CRC) as a soil amendment for carbon dioxide removal (CDR) through enhanced weathering over 10 months. CRC increased soil pH and calcium and bicarbonate concentrations, especially in soils with lower initial pH. Most sites showed bicarbonate to cation ratios indicative of CRC dissolution by soil carbonic acid. Bicarbonate export limited CDR rates to 0-0.52 tonnes CO2/ha. Life-cycle analysis suggests a 11% discount for CO2 emissions from CRC processing.
Clarkson, M. O., Larkin, C., Swoboda, P., Reershemius, T., Suhrhoff, J. T., Maesano, C. N., & Campbell, J. (2023). A Review of Measurement for Quantification of Carbon Dioxide Removal by Enhanced Weathering in Soil.Synopsis: Limiting global warming to <2°C requires CDR alongside rapid emissions reductions. Terrestrial enhanced weathering using Ca- and Mg-rich silicates in soils could remove gigatonnes of CO2 annually. However, measuring, reporting, and verifying (MRV) this is challenging. This review covers methods for monitoring EW, focusing on geochemical characterization and final carbon storage in oceans. Solid and aqueous phase measurements, alongside gas phase measurements, each have strengths and limitations. Effective MRV strategies and well-designed experiments are crucial for the early EW CDR industry.
Geerts, L. J., Hylén, A., & Meysman, F. J. (2024). Review and syntheses: Ocean alkalinity enhancement and carbon dioxide removal through coastal enhanced silicate weathering with olivine. EGUsphere, 2024, 1-46.Synopsis: Coastal enhanced silicate weathering (CESW) using minerals like olivine aims to increase ocean alkalinity and CO2 sequestration. However, uncertainties about efficiency and impact remain due to a lack of large-scale field studies. This review highlights the need for pilot studies to address these gaps and examines how sediment type affects olivine dissolution and alkalinity generation.
Sitch, S., O'Sullivan, M., Robertson, E., Friedlingstein, P., Albergel, C., Anthoni, P., ... & Zaehle, S. (2024). Trends and drivers of terrestrial sources and sinks of carbon dioxide: an overview of the TRENDY Project. Global Biogeochemical Cycles.Synopsis: The TRENDY project, using Dynamic Global Vegetation Models, provides updated estimates of land-atmosphere carbon exchange. From 2012-2021, results show a large global carbon sink in natural vegetation, mainly due to CO2 fertilization and climate effects, offset by land use emissions. The net land sink is 1.7 PgC/yr, with the largest exchange in extratropical regions.
Zhang, Q., Chen, X., Zhou, X., Nie, X., Liu, G., Zhuang, G., ... & Ma, A. (2024). Tibetan Plateau grasslands might increase sequestration of microbial necromass carbon under future warming. Communications Biology, 7(1), 686.Synopsis: Microbial necromass carbon (MNC) indicates soil carbon sequestration capacity.

Weber, M., Wise, M., Lamers, P., Wang, Y., Avery, G., Morris, K. A., & Edmonds, J. (2024). Potential long-term, global effects of enhancing the domestic terrestrial carbon sink in the United States through no-till and cover cropping. Carbon Balance and Management, 19(1), 18.Synopsis: Achieving a net zero GHG economy in the US requires deep mitigation and CDRs. Enhancing the terrestrial carbon sink through no-till and cover cropping can help, but may affect US agricultural outputs and global markets. An integrated model in this study shows that valuing all terrestrial carbon promotes afforestation, while valuing soil carbon boosts no-till and cover cropping adoption. Targeted carbon incentives can increase the carbon sink with minimal impact on crop availability. Future studies should model non-CO2 GHGs, carbon storage, and cost considerations.
Dong, B., Wang, S., Thorin, E., Sun, Q., & Li, H. (2024). Negative emission potential from biomass/waste combined heat and power plants integrated with CO2 capture: an approach from the national perspective. Journal of Cleaner Production, 142917.Synopsis: Integrating CO2 capture in biomass or waste-fired CHP plants is crucial for achieving negative emissions. Using Sweden as a case study, a dynamic model shows that maximizing CO2 capture can achieve 8.7 million tons of negative emissions annually. Maintaining electricity generation reduces this to 4.3 million tons. Costs are $36.9/tonCO2 and $52.0/tonCO2, respectively. Biogenic fraction significantly impacts outcomes, requiring 32.8%-84.3% to meet Sweden's climate goals.

Liu, C., Chen, T., Zhang, F., Han, H., Yi, B., & Chi, D. (2024). Soil carbon sequestration increment and carbon-negative emissions in alternate wetting and drying paddy ecosystems through biochar incorporation. Agricultural Water Management, 300, 108908.Synopsis: Biochar incorporation in rice paddies, especially under alternate wetting and drying (IAWD), enhances soil carbon sequestration (SOCS), according to this study. It reduces methane emissions by up to 38% and greenhouse gas intensity by 69%. Biochar combined with IAWD achieves the highest SOCS (56.9 t C/ha) and lowers net global warming potential (-23.0 t CO2-eq/ha). This approach mitigates methane emissions and increases grain yield, demonstrating its potential as a robust strategy for carbon-negative agriculture.

Nature Climate Change, 1-8.Synopsis: This study evaluates the impact of frugivorous animals on forest recovery and carbon sequestration in tropical landscapes. Large birds, critical for dispersing late-successional species, were limited in fragmented areas with <40% forest cover, reducing future biomass potential by 38%. Maintaining forest cover >40% is crucial for optimizing animal contributions to biodiversity and carbon storage, emphasizing the need for active restoration efforts in fragmented landscapes.
Sáez-Sandino, T., Maestre, F. T., Berdugo, M., Gallardo, A., Plaza, C., García-Palacios, P., ... & Delgado-Baquerizo, M. (2024). Increasing numbers of global change stressors reduce soil carbon worldwide. Nature Climate Change, 1-6.Synopsis: This study examines soil carbon responses to multiple global change stressors across diverse ecosystems using data from 1,880 soil samples worldwide. It reveals that increasing numbers of stressors exceeding medium-high levels are linked to significant declines in soil carbon stocks and mineral association across biomes. Low-productivity ecosystems, such as deserts, are particularly susceptible. Understanding these interactions is essential for managing and preserving soil carbon in the face of global environmental changes.

Our group presently conducts experiments at 50 L and 50,000 L scale to understand the effects of increasing alkalinity on marine biogeochemistry. Larger field trials at million litre scale are planned in 2026 and we also monitor several localities in China where high unequilibrated alkalinity concentrations from industrial sources outflow into natural waters. Key questions are whether or not ocean alkalinity enhancement is a cost-effective method of achieving negative emission technology, what side-effects (ecological and chemical) result from alkalinity additions to coastal seawater, and how reproducible the effects of alkalinity enhancement are contrasting different alkalinity sources and localities. More details on forthcoming field activities can be provided at interview."
"Vaulted is an emerging leader in permanent carbon removal. As a Biomass Carbon Removal and Storage (BiCRS) solution, Vaulted delivers permanent, high quality carbon removal at scale through the geologic sequestration of carbon-filled organic waste.Vaulted’s approach is designed to be the lowest cost, gigaton scale, permanent carbon removal. We sequester sludgy organic wastes (biosolids, manure, agricultural, food waste, paper sludge, etc.) that today are sent to a landfill, dumped into an ocean/river, land applied, or otherwise left to decompose, releasing Green House Gases (GHGs) into the atmosphere. Vaulted leverages a suite of patented, mature, geologic slurry sequestration technologies which allow us to sequester organic waste with minimal processing. We inject deep under the earth’s surface, where the carbon is permanently trapped under a layer of impermeable rock - the same formations that have kept hydrocarbons underground for millions of years."
"According to the Intergovernmental Panel for Climate Change (IPCC, 2022), mitigation pathways that offer a 50% chance of limiting end-of-century global warming to 1.5°C rely partly on removal of as much as 1090 billion tons of carbon dioxide from the atmosphere by novel Carbon Dioxide Removal (CDR) technologies. Currently, 0.002 billion tons of carbon dioxide are removed annually from the atmosphere by such technologies. In other words, novel CDR technologies need to be upscaled by as much as a factor of 5000 from present-day levels. Novel CDR technologies involve storing carbon in rocks, of which mafic volcanic rocks (basalts) are of particular interest because carbon storage has been shown to occur by rapid mineralization (Matter et al., 2016). However, most basalts occur beneath the ocean floor, which is unsuitable for storing carbon for practical reasons. Occasionally, rocks of basaltic composition are found on continents. These were brought there (obducted) during mountain building. Typically, obduction is accompanied by metamorphism, a process which transforms basalt into a suite of rocks (metabasalts) that have the same composition as basalt but are made of different minerals. The global potential of metabasalts for CDR is not well established. This four-year project focuses on testing the hypothesis that metabasalts are suitable for CDR by mineralization. The hypothesis will be tested by performing flow through experiments on metabasalts that were formed at different pressures and temperatures. Training will be offered in fieldwork, petrology, experimental and analytical geochemistry and geochemical modelling. The successful applicant will join a team of petrologists and geochemists working on CDR at Stockholm University and Luleå Technical University."

A new study involving scientists from the University of Alberta and the University of Bern could hold the answer. Using the CLS, the researchers determined how best to trap and store CO2 using brucite, a mineral found in certain mining wastes and geologic environments.
