Boeing’s recent multi-year agreement with Grassroots Carbon, securing a minimum of 40,000 tons of durable carbon dioxide removal (CDR) credits, offers a fascinating glimpse into the evolving corporate engagement with nature-based solutions. Grassroots Carbon, a Texas-based provider formed in 2021, focuses on regenerative grazing, partnering with U.S. ranchers to sequester carbon in soil. Their approach emphasizes direct, one-meter deep, field-level soil measurements and laboratory analysis, coupled with third-party verification to recognized carbon standards. This detail about measurement depth and independent verification is crucial, addressing a persistent skepticism around the permanence and verifiability of soil carbon projects. ...

Google’s recent agreement with Commonwealth Sortation LLC, an affiliate of AMP Robotics Corporation, to remove 200,000 metric tonnes of CO2e by 2030 is a fascinating development for the CDR landscape, particularly for those of us tracking diverse removal pathways. This isn’t just another tech giant purchasing offsets; it’s a direct investment in a method that tackles both short-term climate warming and long-term carbon sequestration, leveraging waste management infrastructure. The core of AMP’s approach is the diversion of organic waste from landfills, which are, as the article reminds us, the third largest source of human-generated methane emissions in the U.S. Instead of allowing this organic material to decompose anaerobically and release potent methane, AMP’s AI-powered sortation technology recovers it and converts it into biochar. This biochar is then stable, sequestering carbon for hundreds of years. What’s compelling here is the dual climate benefit: immediately mitigating methane emissions, a super pollutant with a much higher short-term warming potential than CO2, while simultaneously locking away carbon in a stable form. It’s a pragmatic “two birds, one stone” solution. ...

The latest piece from AMCHAM India makes some rather bold claims about a new carbon capture technology that, if even partially true, would represent an seismic shift in the CDR landscape. The article describes a “revolutionary carbon-catching system” employing an “innovative molecular sieve method” using specially engineered nanomaterials. The standout technical claims are its operation at standard temperature with minimal energy input, achieving efficiency rates exceeding 95% – a dramatic jump from the 40-60% typically cited for existing direct air capture (DAC) methods. Furthermore, it asserts the technology’s ability to treat thousands of tons of atmospheric carbon annually per unit, validated in test facilities across three continents. ...

The recent Memorandum of Understanding between Varhad Capital and Velocys to develop “Make-In-India, cost-competitive biomass-to-SAF projects” is a development that merits a close look from our CDR lens, even if carbon removal isn’t the explicit headline. At its core, this agreement focuses on producing Sustainable Aviation Fuel (SAF) from biomass using Velocys’s proprietary Fischer-Tropsch technology. While SAF is crucial for decarbonizing aviation, the immediate question for us is: where does CDR fit into this picture? ...

An Italian infrastructure group has earmarked €1 million to bolster its internal carbon removal unit, as disclosed in its 2025 integrated annual report. While the article from Carbon Pulse doesn’t name the specific group, the allocation itself, despite being a relatively modest sum in the broader climate finance landscape, offers a telling signal for the CDR sector. This isn’t an external purchase of credits on the voluntary carbon market (VCM); it’s a direct, internal investment into developing or scaling proprietary removal capabilities. ...

The latest “Deep Research — CDR Technology Spotlight” provides a timely snapshot of where several key removal pathways stand, and it’s clear the field is maturing, albeit unevenly. The article highlights significant strides in Direct Air Capture (DAC), noting the continued scaling efforts by players like 1PointFive, who recently broke ground on their first large-scale DAC plant in Texas, designed to capture up to 500,000 tons of CO2 annually. This move, backed by significant DOE funding and advance market commitments, signals a shift from pilot to industrial scale, a crucial hurdle for the entire sector. The piece also delves into the persistent challenge of cost, suggesting that while the $100/ton milestone for DAC remains elusive for current commercial operations, innovations in sorbent materials and energy efficiency are pushing projections closer, with some advanced concepts targeting sub-$200/ton within the next five years. ...

Today’s digest covers 2 CDR stories. Themes: science. Today’s stories#Decarbonization pathways for Canada’s federated energy system using a subnational integrated assessment model | npj Climate Action A climate in crisis calls for investment in direct air capture, new research finds | ScienceDaily

The latest research from UC San Diego, published in Nature Communications, offers a fascinating thought experiment on the role of Direct Air Capture (DAC) in addressing the climate crisis. The study posits a “wartime-level” funding scenario, envisioning an emergency response akin to national mobilizations during wars or pandemics. This isn’t just academic; it reflects a growing sentiment that incremental action might no longer suffice. The core finding is striking: if an emergency DAC program were to commence in 2025, receiving an annual investment of 1.2-1.9% of global GDP, it could remove 2.2-2.3 gigatons of CO2 by 2050 and a staggering 13-20 gigatons by 2075. Cumulatively, from 2025 to 2100, this program could sequester 570-840 gigatons of CO2. These figures are squarely within the range that IPCC scenarios suggest will be needed to meet the Paris Agreement’s goals. For context, the entire global energy system currently emits around 37 gigatons of CO2 annually. Imagine scrubbing 20 gigatons in a single year, let alone hundreds over decades. ...

Just read a fascinating study in npj Climate Action by Awais, Azevedo, and McPherson, which digs into Canada’s path to Net Zero by 2050 using their new MESSAGEix-Canada model. This isn’t just another high-level projection; it’s Canada’s first open-source, sub-national integrated assessment model, meaning it actually accounts for the distinct differences across provinces — a crucial detail given Canada’s highly federated energy system and diverse regional economies. The big takeaway? Achieving Net Zero in Canada is technically feasible and, surprisingly, cost-effective at the system level. The study found that a Net Zero scenario doesn’t even require an increase in total energy system investments compared to a “Legislated pathway.” Instead, it’s about reallocating capital — shifting funds away from fossil fuel supply and towards electrification, efficiency improvements, clean hydrogen, and the necessary enabling infrastructure. This is a powerful message: it’s not necessarily more expensive, just different. ...

A new study published on arXiv (Fernandes et al., March 2026) extends the sector-coupled European energy system model PyPSA-Eur to include four CDR pathways that most previous models have ignored or underweighted: afforestation, perennialisation, biochar, and enhanced rock weathering (ERW). The results are striking — and structurally important for anyone thinking about CDR deployment priorities in Europe. The Core Finding: CDR Makes the System 9% Cheaper#The model, run at 3-hourly resolution across 90 European nodes, finds that a climate-neutral energy system equipped with these CDR strategies is 9% less expensive than an equivalent system that relies only on direct electrification and point-source capture. ...
