Ganesan et al. (2025): Pyrolytic conversion of construction, renovation, and demolition (CRD) wood wastes in Québec to biochar: Production, characterization, and identifying relevant stability indices for carbon sequestration

Aravind Ganesan, Olivier Rezazgui, Simon Langlois, Cyrine Boussabbeh, Simon Barnabé IN: Science of The Total Environment, 965, https://doi.org/10.1016/j.scitotenv.2025.178650

There is a scarcity of comprehensively understanding construction, renovation, and demolition (CRD) wood pyrolysis and projecting the biochar product’s stability due to a lack of relevant studies and frequent inconsistencies amidst currently available methods. Nevertheless, in the present study, CRD wood is pyrolyzed in a horizontal tube furnace of two scales under laboratory conditions. Evaluation of biochar stability was carried out by the proximate and ultimate analysis, Van-Krevelen plots, TGA/DTG profile, R50 recalcitrance, SEM-EDX, and Raman ID/IG methods.

Holland-Cunz & Baatz (2025): How to govern carbon dioxide removal: an assessment framework for policy instruments

Antonia Holland-Cunz, Christian Baatz IN: Climate Policy, 2025, https://doi.org/10.1080/14693062.2025.2459315

In this paper, the authors introduce a comprehensive assessment framework designed to evaluate the feasibility and desirability of various policy instruments for governing CDR. The framework is structured around 15 criteria, some of which are value-based, and organized into six key dimensions of interest. This framework is suitable for application at different stages of policy deliberation, planning, and development.

Li et al. (2025): Atmospheric CO2 Removal Efficiency through Enhanced Silicate Weathering in Croplands: A Review with Emphasis on the Contribution of Fungi

Zi-Bo Li, Gaojun Li, Jonathan M. Adams, Dong-Xing Guan, Liang Zhao, Rongjun Bian, Qing Hu, Xiancai Lu, Junfeng Ji, Jun Chen IN: Springer Nature, 36, https://doi.org/10.1007/s12583-024-0101-5

Theoretical studies underscore enhanced silicate weathering’s (ESW) substantial potential for CDR and its diverse benefits for crops when applied to croplands. However, the well-known significant discrepancies in silicate weathering rates between laboratory and field conditions introduce uncertainty in CDR through ESW. By compiling data from recent literature, the authors calculated and compared CDR efficiency (t CO2 tsilicate−1 ha−1 y−1) observed in mesocosm experiments and field trials.

Heimannet al. (2025): Expert projections on the development and application of bioenergy with carbon capture and storage technologies

Tobias Heimann, Lara-Sophie Wähling, Tomke Honkomp, Ruth Delzeit, Alessandra Pirrone, Franziska Schier, Holger Weimar IN: Environmental Research Letters, 20, https://doi.org/10.1088/1748-9326/ada16f

To assess the former pros and cons of Bioenergy with carbon capture and storage (BECCS) deployment, interdisciplinary model approaches require detailed estimates of technological information related to BECCS production technologies. Current estimates of the cost structure and capture potential of BECCS vary widely due to the absence of large-scale production. To obtain more precise estimates, a global online expert survey (N = 32) was conducted including questions on the regional development potential and biomass use of BECCS, as well as the future operating costs, capture potential, and scalability in different application sectors

Nature – Beerling et al. (2025): Transforming US agriculture for carbon removal with enhanced weathering

Planavsky, Maria Val Martin IN: Nature, https://doi.org/10.1038/s41586-024-08429-2

Enhanced weathering with agriculture uses crushed silicate rocks to drive CDR. If widely adopted on farmlands, it could help achieve net-zero emissions by 2050. Here we show, with a detailed US state-specific carbon cycle analysis constrained by resource provision, that EW deployed on agricultural land could sequester 0.16–0.30 GtCO2 yr−1 by 2050, rising to 0.25–0.49 GtCO2 yr−1 by 2070.

Schippers et al. (2025): Bargaining powers in cooperative Carbon Dioxide Removal deployment

Emma Jagu Schippers, Solène Chiquier, Olivier Massol, David Lowing, Niall Mac Dowell IN: Climate Policy, 1-16, https://doi.org/10.1080/14693062.2024.2445167

International cooperation has the potential to significantly reduce the costs of implementing CDR in line with the Paris Agreement. However, the success of interregional cooperation depends on whether a satisfying agreement can be reached. Regional bargaining powers may heavily influence the outcome of such an agreement. This paper uses cooperative game theory to assess bargaining powers in the cooperative deployment of CDR between the United States, the European Union, Brazil, and China.

Reginato (2025): Biotechnology in direct air capture, enhanced weathering, and methane removal: emerging opportunities and gaps

Paul L. Reginato IN: Frontiers in Climate 6, 1440833, https://doi.org/10.3389/fclim.2024.1440833

Due to the interdisciplinarity and novelty of greenhouse gas removal (GHGR) technologies, GHGR research faces challenges of adapting technical disciplines to new domains and broadly empowering researchers with the knowledge necessary to identify and solve key problems. This Perspective discusses the significant, but underexplored, role biotechnology could play in several GHGR technologies as well as the common research, community, and knowledge gaps that are limiting progress. The GHGR technologies of focus are (1) the potential for the enzyme carbonic anhydrase to catalyze CO2 exchange in direct air capture; (2) the potential utility of microbes for accelerating soil-based or reactor-based enhanced rock weathering; and (3) the potential for methanotrophic bacteria or methane monooxygenase enzymes to oxidize methane for atmospheric methane removal via enhanced methanotrophy or bioreactors.

Fu et al. (2025): Tidal-driven N2O emission is a stronger resister than CH4 to offset annual carbon sequestration in mangrove ecosystems

Chunwei Fu, Zhibo Shen, Shiheng Tang, Fengying Li, Xin Quan, Yang Wang, Ya Zhuang, Jiasen Zhong, Jianan Liu, Jianzhong Su, Min Xu, Yu Han, Shuh-Ji Kao, Ehui Tan IN: Science of The Total Environment 964, 178568, https://doi.org/10.1016/j.scitotenv.2025.178568

The mangrove ecosystems store a significant amount of “blue carbon” to mitigate global climate change, but also serve as hotspots for greenhouse gases (CO2, CH4 and N2O) production. The CH4 and N2O emissions offset mangrove carbon benefits, however, the extent of this effect remains inadequately quantified. By applying the 36 h time-series observations and mapping cruises, here the authors investigated the spatial and temporal distribution of GHGs and their fluxes in Dongzhaigang bay, the largest mangrove ecosystem in China, at tidal and monthly scales.

Fritz et al. (2025): Between inflated expectations and inherent distrust: How publics see the role of experts in governing climate intervention technologies

Livia Fritz, Lucilla Losi, Chad M. Baum, Sean Low, Benjamin K. Sovacool IN: Environmental Science and Policy, 164, https://doi.org/10.1016/j.envsci.2025.104005

Addressing questions around more effective governance of novel technologies for removing carbon dioxide from the atmosphere and proposals around solar radiation modification necessitates reflections on how different kinds of expertise, normative judgments and democratic decision-making (should) interact. Based on a survey (N = 22,222) and 44 focus groups (N = 323) in 22 countries, the authors show (i) who publics see as an expert in the field of climate intervention technologies, (ii) what roles they envision for experts in governing climate intervention technologies and (iii) how trust and distrust in scientists unfolds in the context of these novel, partly controversial, technologies.
