Deep Sky, a carbon removal project developer based in Montreal, and Carbfix, the world’s first operator of CO2 mineralization, have partnered to investigate CO2 mineral storage in Canada.
The press release mentions the pre-feasibility study examining potential reservoirs in Quebec for CO2 mineral storage will conclude in June.
The Role of Deep Sky
Deep Sky, renowned for its commitment to developing cutting-edge environmental technologies aims to revolutionize carbon capture and storage practices with this groundbreaking project.
Phil De Luna, Chief Carbon Scientist, Head of Engineering at Deep Sky noted,
At Deep Sky, we’re constantly on the lookout for new technologies that can capture carbon dioxide from the air or the ocean. The principle of engineered carbon dioxide removal (CDR) is relatively simple, separating a gas (CO2) from other gases (air) at very low concentrations. However, there are myriad ways and chemistries to make that separation happen.

Understanding CO2 Mineralization
CO2 mineralization, also known as carbon capture and storage (CCS) through mineralization. It involves the conversion of CO2 into stable mineral forms through chemical reactions with certain rocks. This process mimics and accelerates the natural geological carbon sequestration process, locking away CO2 for thousands of years.
Notably, Carbfix is a pioneer in “converting CO2 into stone”. The unique technique involves injecting CO2 into basaltic rock formations. Subsequently, reacting with minerals to form stable carbonates, effectively trapping the CO2 underground.
According to Carbfix, the company has injected 103, 273.5 MTs of CO2 since 2014.
It believes Europe alone can “theoretically” store at least 4,000 billion tons of CO2 in rocks while the United States can store at least 7,500 billion tons.

Let’s understand how the joint venture will help implement the process.
Project Implementation
In this partnership, the companies will screen geological and geochemical data of the selected subsurface. They will conduct laboratory work on ultramafic rock formations in various Quebec regions of Canada.
The CO2 mineralization storage project will involve the following key steps:
1. Site Selection: Identifying suitable basaltic rock formations for CO2 injection based on geological characteristics and proximity to emission sources.
2. Injection Process: Injecting CO2 captured from industrial sources into the selected basaltic reservoirs at controlled pressures and temperatures to initiate the mineralization reaction.
3. Monitoring and Verification: Implementing rigorous monitoring and verification protocols to assess the effectiveness of CO2 mineralization, track carbon storage volumes, and ensure the long-term integrity of storage sites.
4. Scaling Up: Scaling up the project to demonstrate its feasibility for large-scale deployment across various industrial sectors and geographical regions.
Subsequently, this data will assess the formations’ potential for in-situ carbon mineralization and safe, permanent CO2 sequestration. This is how their unique process transforms CO2 into stone underground within a couple of years.

Potential Impact of Deep Sky-Carbfix Collaboration
The successful implementation of the Deep Sky-Carbfix CO2 mineralization storage project holds immense promise for addressing the global climate crisis. Some key anticipated impacts include:
Carbon Emission Reduction: It can significantly reduce carbon emissions from industrial sources by capturing and storing CO2 in mineral form. Thereby helping to meet emission reduction targets outlined in international climate agreements.
Climate Mitigation: It would contribute to climate mitigation efforts by removing CO2 from the atmosphere and preventing its release. Thus, mitigating the adverse effects of global warming and climate change.
Technology Adoption: It can enhance the adoption of CO2 mineralization technology as a cost-effective and sustainable CCS solution across various industries.
The company aims to rapidly and permanently store one billion tons of CO2 (1GtCO2) to play a pivotal role in addressing the climate crisis.
Edda Aradottir, Carbfix CEO commented,
“Our partnership with Deep Sky demonstrates Carbfix’s dedication to pioneering sustainable value chains and solutions for safe and permanent carbon storage. This collaboration in Québec is a key step towards realizing global net-zero ambitions, illustrating our shared commitment towards climate recovery.”
By partnering with Carbfix, we believe Deep Sky has combined its innovative approach with the former’s state-of-the-art CO2 mineralization technology.

The Strategic Case for Nature-Based Carbon Investments
Nature-based carbon investments deserve consideration when they address a specific business dependency and produce outcomes you can measure. Imagine Moonbucks, a global coffee roaster planning next season’s espresso blend. It is considering natural Grade 4 coffee from Jimma, in southwestern Oromia, Ethiopia. Its sourcing decisions affect the roasting schedule and the cash tied up in coffee purchases. Moonbucks needs to understand which measures could protect that supply, what they would cost and how it would judge the results.
1. Define the sourcing problem before choosing a project
Moonbucks needs a dependable component for its espresso blend. Its procurement team wants continuity of volume and an agreed cup profile. Replacing a shipment at short notice could require new sample approval and changes to the blend, and given the schedules for cultivation, processing, and freight delivery, is practically impossible. Moonbucks needs to get this right, and its initial concern is inconsistent deliveries. It commissions an assessment of the supplying farms and post-harvest chain. The questions cover land condition, harvest availability and whether drying or storage problems are affecting saleable lots.
This distinction changes the investment brief. A tree-planting proposal cannot be assumed to fix drying problems. Better storage cannot restore eroded land. The team must establish which problem exists before selecting the response.
CCC’s guide to finding nature-based solutions in your supply chain explains where to look. Here, the next task is to turn a broad concern into a testable proposal.
2. Develop nature-based carbon investments around the actual supply chain
The assessment would trace Moonbucks’ purchases back through the exporter and supplying producer groups. Which farms supply the contracted lots? Who controls land-management decisions? How long does the buyer expect to maintain the purchasing relationship?
Furthermore, Jimma natural Grade 4 cannot be treated as interchangeable with every Ethiopian coffee. Moonbucks would need to test any substitute against its own blend and quality requirements.
Suppose Moonbucks’ assessment identifies an opportunity to maintain shade trees and restore vegetation along exposed streambanks. The IPCC describes agroforestry as a way to store carbon in vegetation and soil, with potential benefits for erosion control and water quality.1 Moonbucks would need local advice on species, growing conditions and maintenance before deciding how these measures fit its sourcing plan.
The proposal now has a defined sourcing connection and a candidate intervention. The next steps are to test its effect on production, assess carbon eligibility and build the financial case.
3. Compare the proposal with other ways to protect supply
WBCSD’s Nature-based Solutions Blueprint recommends comparing nature-based options with other responses across their benefits and costs.2 For Moonbucks, that means evaluating the landscape proposal alongside drying improvements, storage controls and alternative sourcing arrangements.
The product’s natural-process designation matters. Moonbucks should examine the drying and dry-milling chain alongside land conditions. Its team would check storage practices, contamination risks and incoming-lot quality to see whether problems arise before or after the coffee leaves the farms.
The revised proposal might combine land stewardship with separate post-harvest controls. Each component needs its own purpose and budget. A sustainability label should not obscure which activity is expected to solve which problem.
The project develops as the evidence improves. Its scope should follow the diagnosis rather than preserve the first idea unchanged.
4. Establish what the carbon outcome could count toward
Moonbucks’ sustainability team now tests the proposed carbon case separately from the sourcing case. Is the objective a measurable change in Moonbucks’ value-chain emissions, verified credits for separate voluntary use, or distinct outcomes under carefully defined arrangements?
Scope 3 covers value-chain emissions. A purchasing relationship alone does not prove that a farm intervention can be included in Moonbucks’ inventory. The team needs an applicable accounting method, defensible boundaries and evidence supporting attribution.
SBTi’s FLAG Guidance (forest, land and agriculture), version 1.2, says purchased credits used as offsets cannot meet near-term FLAG or energy and industry targets. Eligible land-based removals are subject to accounting requirements.3 Moonbucks needs to test its proposal against those rules before including an outcome in its targets.
For Moonbucks’ Jimma proposal, maintaining existing trees and establishing new vegetation could involve different carbon questions. Specialists must examine the baseline and additionality, meaning what changes because the project proceeds. They must also assess measurement and the risk that stored carbon is lost. CCC’s MRV and additionality article introduces those tests.
Until that work is complete, Moonbucks should not budget an assumed Scope 3 reduction or credit-sale receipt. Direct emissions reductions remain the priority.
5. Build a financial case that survives weaker assumptions
Moonbucks’ finance team would now build a multi-year budget. UNEP’s State of Finance for Nature 2023 compares current finance with the investment needed to meet climate, biodiversity and land-restoration goals.4 The company would cost its proposed activities, farmer participation and ongoing monitoring. Verification, where required, is a separate expense. Maintenance and responsibility for replacing failed plantings must remain visible after the initial establishment budget ends.
Operational benefits need equally careful treatment. If fewer rejected lots reduce emergency purchasing, count that saving once. Do not add “supply resilience” as another financial benefit when it represents the same avoided cost.
Moonbucks should compare a base case with slower benefits, higher implementation costs and no carbon revenue. It should also distinguish production outcomes from quality and shipment outcomes. A single good harvest would not prove that the landscape intervention caused better delivery performance.
A project can remain worth funding even when its carbon case needs more work. That decision must rest on the operational evidence and the company’s objectives, without unsupported environmental claims.
6. Fund a pilot with a clear expansion decision
Moonbucks’ first approval would fund a bounded pilot, rather than commit the entire sourcing program. Before spending, Moonbucks would agree on participating farms, responsibilities and the evidence needed at review.
Its scorecard could track farmer participation, implementation costs and plant survival, alongside accepted coffee volumes and lot-quality results. Carbon measurements would follow the selected method. Farm-level traceability must connect the intervention to the actual sourcing relationship.
Suppose Moonbucks’ review later finds that storage changes explain most quality improvements, while the land measures need longer observation. Those findings would shape the next decision: expand the proven component, adjust the landscape work or pause further spending. They would not justify crediting all improvements to tree planting.
This gives nature-based carbon investments a practical place in a multi-year strategy. Funding increases as the evidence supports it, and the project can change direction before a larger commitment.

EU carbon credit claims after 27 September 2026
EU carbon credit claims changed on 27 September 2026, the day the Directive (EU) 2024/825 began to apply across the European Union. The change is narrow. It changes how a company can talk about the credits it buys. A product can no longer be called neutral on the strength of compensation alone; however, every specific, evidenced statement about what a company measured, reduced, and funded stays fully available.
