Dong et al. (2025): Warm and wet anomalies persist across the Pan-Arctic after carbon dioxide removal

Xiao Dong, Chao Min, Hao Luo, Jiangbo Jin and He Zhang, IN: Environmental Research Letters, https://doi.org/10.1088/1748-9326/ae24f2

The pan-Arctic region is experiencing rapid climate change under global warming, with Arctic Amplification occurring at a rate 2–3 times faster than the global average. This study investigates the climate responses in the Pan-Arctic region under carbon dioxide removal (CDR) scenarios using nine CMIP6 models from the Carbon Dioxide Removal Model Intercomparison Project (CDRMIP).

Gill et al. (2025): The Physiological Response of Contrasting Coccolithophore Species to Ocean Alkalinity Enhancement

Sophie Gill, Jiayou Ge, Qiong Zhang, Gideon M. Henderson, Rosalind E. M. Rickaby, IN: Journal of Geophysical Research: Biogeosciences, https://doi.org/10.1029/2025JG009103

Environmental impacts related to the Ocean Alkalinity Enhancement (OAE) on marine biota remain underexplored. Ocean Alkalinity Enhancement aims to increase the ocean’s total alkalinity (TA), shifting the carbonate buffer system to prompt air-sea gas exchange and CO₂ drawdown. These conditions might be favorable for calcifiers, leading to increased removal of alkalinity in CaCO₃ and reversing some of the intended benefit of the OAE. Here, the authors parameterize the impact of increased ocean alkalinity on two dominant end-member coccolithophore species: Gephyrocapsa huxleyi and Coccolithus braarudii.

O’Keefe et al. (2025): Net-zero for Canada: An open-method modeling approach

Kowan T.V. O’Keefe, Matthew Binsted, Leon Clarke, Ryna Cui, Nathan Hultman, Robert Hunt Sprinkle, IN: Energy and Climate Change, https://doi.org/10.1016/j.egycc.2025.100224

Canada is a major oil- and gas-producing country that has committed into law an ambitious goal: net-zero greenhouse gas (GHG) emissions economy-wide by 2050. In this work, transition dynamics for Canada are examined across several net-zero GHG emissions scenarios with detailed policy representation using the open-source Global Change Analysis Model (GCAM). To the authors knowledge, this study is the first modeling analysis of Canadian net-zero GHG emissions scenarios with extensive policy representation and detailed sensitivity analysis. A major contribution of the authors’ open-method modeling approach is making the entire analysis publicly available to facilitate vetting, replicability, precise comparability with other studies, and modification by others to explore additional scenarios.

Wang & You (2025): Cropland Enhanced Weathering in Low GDP Regions for Gigaton Scale Carbon Removal with Potential Economic Co-benefits

Bingzheng Wang and Fengqi You, IN: Environmental Research Letters, https://doi.org/10.1088/1748-9326/ae1cd4

Enhanced rock weathering (ERW) applies crushed silicate rocks like basalt to croplands and offers significant potential for atmospheric carbon dioxide removal (CDR). Here, the authors explored the potential of ERW as a bridge for sharing decarbonization responsibilities, with less-developed regions contributing cropland deployment and more developed regions providing financial support, thereby enhancing equity in global decarbonization.

Nature – Bossy et al. (2025): Spaces of anthropogenic CO₂ emissions compatible with climate boundaries

Thomas Bossy, Philippe Ciais, Katsumasa Tanaka, Franck Lecocq, Philippe Bousquet and Thomas Gasser, IN: Nature Climate Change, https://doi.org/10.1038/s41558-025-02460-5

Climate boundaries are planetary boundaries for the climate system: limits within which humanity can sustainably prosper. Here the authors introduce a modelling framework to analyse global warming, ocean acidification, sea-level rise and Arctic sea-ice melt. Using a reduced-form model, they map out anthropogenic CO₂ emissions, carbon dioxide removal and solar radiation management pathways compatible with these boundaries. They define safety levels as the probability to stay within one or several boundaries considering physical uncertainty.

Kuwae et al. (2025): Empirical analysis of project–purchaser dynamics in Japan’s blue carbon dioxide removal credit scheme

Tomohiro Kuwae, Yuka Suzuki and Masanori Furuya, IN: Research Square, https://doi.org/10.21203/rs.3.rs-7525613/v1

Carbon dioxide removal (CDR) and associated credit mechanisms are gaining prominence in carbon neutrality strategies, yet empirical evaluations of their sustainability remain limited. Here, the authors analyzed 61 blue carbon projects and 471 certified transactions under Japan’s J-Blue Credit scheme to examine the characteristics of projects and purchasers and their interrelationships.

Presty et al. (2025): Global Collaboration in Carbon Dioxide Removal: Navigating a Fragmented Landscape

Romain Presty, Olivier Massol and Pascal Da Costa, IN: Clean Technologies and Environmental Policy, https://doi.org/10.1007/s40518-025-00280-x

As carbon dioxide removal (CDR) becomes an increasingly important component of net-zero strategies, understanding how scientific collaboration is structured globally is essential. This review applies bibliometric methods to map and analyze co-authorship networks, institutional communities, and thematic structures in CDR-related research from 2015 to 2024, using Web of Science data.

Clarkson et al. (2025): Unlocking Gigatonne-scale Carbon Dioxide Removal with strategic tipping point frameworks

Matthew Oliver Clarkson, Mariane Chiapini, Marcella Daubermann, Veronica Furey, Suzi Huff Theodoro, Injy Johnstone, Junyao Kang, David Manning, Igor Nogueira, Eduardda Pivatto, Noah J. Planavsky, Bruno Ramos, Mayra Maniero Rodrigues, Leticia Schwerz, Philipp Swoboda, Jeandro Vitorio and Christina Larkin, IN: EarthArXiv Preprint, https://doi.org/10.31223/X56J15

This study explores the enabling conditions and interventions that place Brazil at the forefront of uniting the emerging Enhanced Rock Weathering industry with sustainable agrogeological transformation. These conditions include pioneering research, an established community movement and representation body, and a ‘first-of-its-kind’ national legal framework for feedstock production.

Malakar et al. (2025): Beyond environmental identity: Testing public support for novel carbon dioxide removal in Australia using structural modelling

Yuwan Malakar, Chad M. Baum, John Gardner, Kerryn Brent, Talia Jeanneret, Livia Fritz and Benjamin K. Sovacool, IN: Journal of Environmental Management, https://doi.org/10.1016/j.jenvman.2025.127633

Climate change presents a significant environmental challenge, and novel carbon dioxide removal (CDR) technologies are increasingly recognised as critical strategies for mitigation. Although many of these technologies are still under development, support and governance remain uncertain. Public acceptance is key to large-scale CDR deployment, yet research on this topic is limited, particularly in the Southern Hemisphere. This study focuses on Australia, where interest in novel CDR is gaining momentum in both research and policy domains. The authors examine two key questions: (1) To what extent does the Australian public support novel CDR? and (2) What factors influence this support?

Public acceptance is key to large-scale carbon dioxide removal (CDR)deployment, yet research on this topic is limited, particularly in the Southern Hemisphere. This study focuses on Australia, where interest in novel CDR is gaining momentum in both research and policy domains. The authors examine two key questions: (1) To what extent does the Australian public support novel CDR? and (2) What factors influence this support? Using a nationally representative survey of 340 members of the Australian public, with quotas set for age, gender, geographic region, income and education, they explore public perceptions of four CDR approaches: Direct Air Capture with Carbon Storage, Bioenergy with Carbon Capture and Storage, Enhanced Rock Weathering, and Biochar. The authors develop and validate a structural model to understand how an interplay of factors shapes public perceptions of novel CDR, including perceived benefits and risks, trust in institutions, concerns about tampering with nature, and the environmental self-identity of participants.
