THIS WEEK’S TOP CDR HIGHLIGHTS
POLICY: The European Commission has published a legislative proposal for an EU Climate Law, setting a 90% net emissions reduction target for 2040. Permanent CDR is explicitly recognised as essential, with a clear signal that it should be integrated into the EU ETS. However, no separate target for CDRs has been set. Carbon Gap has released a brief arguing that separate CDR targets for 2040 are both feasible & necessary to reach EU net zero. Read reactions from Politico, S&D, Renew, Euractiv & The Guardian, & listen to the discussion on this topic on the CDR Policy Scoop podcast.
POLICY: The European Commission is also looking into applying a "conversion factor" for CDR credits when they are traded on the EU's Emissions Trading System.
REQUEST FOR PROPOSALS: Planet2050 launched its first RFP to invest up to €2M each in 3–5 early-stage CDR projects focused on durable engineered pathways like biochar, BECCS, bio-oil, weathering, and mineralization. Deadline to apply: 22 July 2025
RESOURCE: Milkywire has released a 5-part weekly CDR email series explaining CDR’s role in net zero, credits, buyer needs, policy trends, diversification, and best practices for getting started with CDR.
WORLD’S FIRST NEGATIVE-CARBON DIAMONDS: India’s Ramkrishna Exports (SRK) becomes the world’s first to craft natural diamonds with a verified negative carbon footprint, removing more CO₂ than emitted (–0.239 kg CO₂e/carat).
RESEARCH PAPER: Governments and companies banking on future deployment of CO2 removal innovations to meet climate targets risk facing sharp economic costs and abrupt energy transitions if those technologies fail to deliver at scale, a new study has warned. Listen to the discussion on this paper here.
REMOVE ACCELERATOR APPLICATION: Remove launched EU CDR accelerator applications for early-stage startups (apply by September 8).

RESEARCH PAPERS
Efficient carbon sequestration of calcium carbide slag based on additive regulation
Authors: Zhiyan Liu, Li Hou, Jun Li, Zhongyuan Lu
Synopsis: Calcium carbide slag shows promise as a CO₂ adsorbent but faces kinetic limits. This study tests additives (MEA, DEA, TEA, NaHCO₃) and flow rates to boost carbonation. NaHCO₃ speeds initial uptake by supplying ions, while MEA improves mid-stage efficiency via carbamate pathways. All additives form pure calcite with distinct crystal shapes. Higher CO₂ flow rates aid mass transfer. Results highlight MEA and NaHCO₃’s potential but stress the need for recycling and industrial scalability research.
Evaluating temporal trade-offs in climate effects from carbon dioxide removal strategies across different metrics: a case study on wetland restoration
Authors: Stavroula Stephane Sartzetakis, Tianyi Sun, Yangyang Xu, Emily Ury, Ilissa Bonnie Ocko and Brian Buma
Synopsis: Carbon dioxide removal can cut CO₂ but may boost short-lived climate forcers like methane, creating near-term warming. Standard CO₂e metrics often miss these trade-offs. This study compares GWP, Technology Warming Potential (TWP), and reduced-complexity models using wetland restoration as a case. TWP and models better capture temporal effects than dual CO₂e. Results stress assessing CDR trade-offs over time, with TWP recommended for practical, robust climate evaluations.
Assessing potential implications of the EU's carbon dioxide removal strategy on Brazil's land ecosystems and local communities
Authors: Soterroni, Antonella Mazzone, Jiesper Tristan
Synopsis: The EU’s 2050 climate neutrality plans rely on land-based CDR like BECCS, but this may shift pressures onto the Global South. Using Brazil as a case, this study shows large EU-driven land demand could trigger deforestation, biodiversity loss, and community displacement, risking green neo-colonialism and Brazil’s own climate goals. It calls for fair, participatory policies to balance EU CDR ambitions with social and environmental justice in host countries.
Risks of relying on uncertain carbon dioxide removal in climate policy
Authors: Matilyn Bindl, Morgan R. Edwards & Ryna Yiyun Cui
Synopsis: Future climate scenarios often rely on large-scale CDR, but its real feasibility is uncertain. Using decision analysis with GCAM, this study shows that planning for high CDR delays fossil fuel cuts until mid-century. If CDR falls short, stranded assets could rise by 38% due to rushed transitions. In contrast, planning for low CDR now makes it more feasible to meet a 1.5 °C target by century’s end. Robust strategies should hedge CDR uncertainty with early emissions cuts and diverse options.
Degrees of reversibility of ocean deoxygenation in an atmospheric carbon dioxide removal scenario
Authors: Estela A Monteiro, David Peter Keller, James Christian, Jasmin G John, Michio Kawamiya, Roland Séférian, et al.
Synopsis: This study uses CDRMIP simulations to examine how carbon dioxide removal affects ocean oxygen. Models show that after CO₂ returns to pre-industrial levels, upper ocean oxygen mostly recovers (97–99%) and can even overshoot, while the deep ocean stays deoxygenated for centuries due to circulation lags. This lasting deep-ocean impact could disrupt redox processes and marine life, highlighting that while CDR helps the atmosphere, ocean recovery varies with depth and timescale.
Little big: Sizing up the risk of mitigation deterrence from carbon removal
Authors: Nils Markusson
Synopsis: This essay argues that the risk of carbon dioxide removal (CDR) deterring broader mitigation is real but often underestimated. While some believe CDR is too minor to hinder emissions cuts or that other factors matter more, the essay counters that CDR’s political and discursive effects can undermine climate action. By reframing CDR as entangled with politics and narratives, it strengthens the case for addressing mitigation deterrence and justifies efforts to avoid it.
Recognizing the value of municipal solid waste resource utilization in delivering carbon dioxide removal
Authors: Xu Chu, Zixuan Fei, Xiankun Wang, Ping Jiang, Wei-Chiao Huang
Synopsis: This paper shows that municipal solid waste (MSW) resource utilization in Shanghai can significantly cut greenhouse gas emissions. Using IPCC methods, results indicate that sorting and recycling MSW (Scenario 2) could reduce emissions by 325 Mt CO₂ from 2020–2030, exceeding Shanghai’s 2030 carbon peak goal. The approach also offers economic benefits worth up to 2.21% of Shanghai’s Q1 2025 GDP, highlighting its feasibility for China’s climate targets.
Life cycle assessment of electrochemical pH-swing direct air capture
Authors: Houssam Bouaboula, Youssef Belmabkhout, Abdelghafour Zaabout
Synopsis: Electrochemical pH-swing DAC shows promise for net-negative emissions if powered by low-carbon electricity (<0.3 kgCO₂eq/kWh). This cradle-to-grave life-cycle assessment finds it outperforms conventional HT-Aq DAC by up to 20% in global warming impact. Yet, high water, metal, and land demands limit other environmental benefits. Using captured CO₂ for methanol synthesis can negate GW gains unless excess CO₂ is stored. Clean energy and careful CO₂ use are key for sustainability.
Ocean liming effect on a North Atlantic microbial community: changes in composition and rates
Authors: Inês De Castro, Susana C. Ribeiro, Antonio Miguel Louvado, Newton Carlos Marcial Gomes, Mário Cachão, Eduardo Brito De Azevedo, Joana Barcelos E Ramos
Synopsis: Ocean Alkalinity Enhancement via liming can remove CO₂ and ease ocean acidification but its ecological impacts are unclear. This study shows OAE delayed phytoplankton growth and boosted bacterial enzyme activity in a North Atlantic plankton community, with Oceanospirillales increasing in abundance. Results suggest OAE may alter microbial dynamics and organic matter cycling. More research is needed to assess long-term effects on marine ecosystems and ensure safe deployment.
Exploring key dimensions of policy instruments for carbon dioxide removal
Authors: Malte Winkler, Soyoung, Antonia Holland-Cunz, Matthias Honegger, Matthias Poralla, Alicia Vollmer & Axel Michaelowa
Synopsis: Integrating CDR into climate policy needs more than carbon markets; non-market tools also matter. This study uses a CDR-specific framework to assess four policy options, from EU Carbon Contracts for Difference to global carbon takeback obligations. No single instrument excels across feasibility, effectiveness, societal impact, and fairness, so careful, inclusive policy design is vital. A tailored mix of policies will best support fair and effective global CDR deployment.
The soil microbial carbon pump for carbon sequestration
Authors: Longkai Qiao, Junfei Wang, Shuangshuang Wei, Yilong Ren, Eric Lichtfouse & Jie Han
Synopsis: CO₂ levels have risen from 280 ppmv (1850) to 430 ppmv (2025), driving global temperatures up +1.49 °C, nearly reaching the Paris Agreement’s 1.5 °C limit. This warming risks severe impacts like sea-level rise and extreme events. Rapid solutions like radiative forcing geoengineering and enhanced carbon capture are increasingly researched. This review highlights soil carbon pools, microbial carbon capture, and synthetic communities as key tools for climate mitigation.
Enhanced Carbon Sequestration Potential Following Sediment Dredging in River Ecosystems: Insights into CO2 Fluxes, Phytoplankton, and Carbon Fixation Pathway Responses
Authors: Zhuo Hao, Shibo Chen, Qingwen Zhang, Bing Liu, Shanghong Chen
Synopsis: This study reveals how sediment dredging affects river carbon dynamics. Over three years, dredging changed CO₂ fluxes and microbial communities, shifting from Cyanobacteria to Gammaproteobacteria and Flavobacteria, boosting chemoautotrophic carbon fixation. Despite initial declines in phytoplankton biomass, carbon sequestration rebounded above pre-dredging levels. Findings show river systems’ resilience and highlight key microbial and metabolic pathways driving carbon storage.
Toward Energy-Efficient Greenhouse CO2 Enrichment: Advancements and Challenges in Direct Air Capture with Solid Sorbents
Authors: Ismail Filahi, Ayalew H. Assen, Mohammed Ouikhalfan, Karim Adil, Youssef Belmabkhout
Synopsis: Sustainable greenhouse farming needs efficient CO₂ enrichment, but tanked or fossil-based CO₂ is costly and carbon-intensive. Direct Air Capture (DAC) with solid sorbents offers a cleaner, decentralized alternative, boosting CO₂ from ~400 to ~1000 ppm for optimal yields while using less energy than traditional CCS. This review explores recent advances in DAC sorbents like zeolites and MOFs, comparing performance, energy needs, and costs to guide greener CO₂ enrichment in greenhouses.
Bioenergy with Carbon Capture and Storage (BECCS): Case Study of Pakistan (2015‐2024)
Authors: Mushtaq Ahmad, Basit Ali, Muhammad Ilyas, Shah Hamdani, Aiman Sher and Muhammad Yasir
Synopsis: This study assesses Pakistan’s potential for Bioenergy with Carbon Capture and Storage (BECCS) from 2015–2024. Despite ample biomass from agriculture, BECCS progress is slow due to technological, financial, and policy barriers. Yet, integrating BECCS could support Pakistan’s climate targets and energy security. The case study highlights pathways for policymakers to advance BECCS as a key negative emissions solution in the country’s sustainable energy transition.
Point-source carbon capture and direct air capture – A technology overview
Authors: Adnan Ozden, Mingchuan Luo, Yanwei Lum
Synopsis: Continuous CO₂ emissions drive climate challenges, requiring carbon capture and removal to meet Paris Agreement goals. This review examines point-source CO₂ capture, used in power, industry, and gas processing, and direct air capture, which offsets diffuse emissions like transport and wildfires. It highlights recent advances, benefits, challenges, and key research needs to improve feasibility and effectiveness of these two leading CO₂ mitigation technologies.
Agroforestry: Mitigating Climate Change Through Carbon Sequestration
Authors: Subhabrata Panda
Synopsis: Agroforestry integrates trees, crops, and livestock, boosting productivity and storing carbon to fight climate change. Trees and shrubs enhance soil quality and carbon retention while diversified systems reduce emissions from fossil fuels. This nature-based solution not only sequesters CO₂ through photosynthesis but also supports rural livelihoods and resilience. Agroforestry is a key sustainable strategy for climate mitigation and sustainable land use.
Pyrogenic Carbon and Carbonating Minerals for Carbon Capture and Storage (PyMiCCS) Part I: Production, Physico-Chemical Characterization and C-Sink Potential
Authors: Johannes Meyer zu Drewer, Maria-Elena Vorrath, Thorben Amann, Jens Hartmann, María De La Rosa, et al.
Synopsis: Meeting Paris climate goals needs gigaton-scale CDR, but co-benefits from combining methods are underexplored. This study tests PyMiCCS—co-pyrolyzing biomass with silicate rock powder—to produce rock-enhanced biochars. These showed greater nutrient content, liming, and C-sink potential, with good thermal stability but mixed impacts on porosity and conductivity. While co-pyrolysis didn’t cut carbon yield, more research is needed on how rock coatings affect weathering and long-term CDR.

Climate Policy and Carbon Removal Uncertainty | Remove and Reflect Podcast
"This episode covers a scientific article that examines the risks associated with climate policies that rely heavily on uncertain carbon dioxide removal (CDR) technologies. Using an integrated assessment model (GCAM), the authors analyze scenarios where planning for high CDR levels might lead to delayed fossil fuel phase-out and potentially higher temperatures or increased economic costs if these technologies don't materialize as expected. Conversely, planning for lower CDR can accelerate energy transitions and offer the flexibility to achieve more ambitious climate goals if high CDR becomes feasible. The study emphasizes the importance of robust climate strategies that account for the uncertainties and potential inequities related to future CDR deployment."
