Durable CDR Credits
From CO₂ to carbonates
Construction materials could store over 16 Gigatonnes of CO₂ per year, with concrete holding the biggest potential – 80% of the total CO₂ storage capacity.
Carbonaide’s innovative technology enables a carbonation process where calcium ions from the cement dissolves naturally, mineralizing the CO₂ as carbonate minerals.
The carbonation process takes place in gas-tight curing chambers with optimal conditions for high mineralization rates. Around 100 kg of CO₂ is stored per cubic meter of concrete in atmospheric pressure (the stored amount varies significantly depending on production details such as the cement type, material mix etc. – please contact us for exact estimates).
Ensuring high-integrity
Additionality
CO₂ mineralization is not required by policy or regulations, and CDR revenues enable the economic viability of the process. No double claiming occurs, as the activity is not included in EU or national GHG accounting.
Permanence
Mineralized CO₂ is stored forever (>1000 years), with carbonate minerals not being released back into the atmosphere, even if the concrete is demolished and recycled.
Quantification
The process module quantifies the mineralized CO₂ through gas flux measurement.
Laboratory-tested control samples confirm the accuracy of the software.
Certification
Durable CDR credits are independently verified, and certified.
The project is certified under Isometric’s module: CO₂ Storage via Carbonation in the Built Environment.
Why to purchase Carbonaide’s CDR credits?
- Support engineered durable CDR credits, adhering to the strictest certification standards.
- Neutralize ongoing emissions effectively, by shifting from "offsetting" to investing in high-durability CDR credits, ensuring that any carbon released is permanently removed from the atmosphere.
- Be a catalyst for scaling the market – building up large-scale volumes of durable CDR in 2040 or 2050 requires investment in different technologies today.
- Become an early buyer of durable CDR to ensure future supply, credible short- and long-term net-zero strategy, and readiness for upcoming regulations.
Reach out
If you are interested in learning more about Carbonaide’s credits, please fill out the contact form below. We have two operational facilities in Finland starting CDR activities in 2026.
In addition, we are looking for catalytic buyers enabling future storage locations by committing to pre-purchase agreements.
At Carbonaide, we see decarbonisation of the concrete industry and carbon removal not as a distant solution but as a practical tool that can be deployed at scale to match the urgency of the climate crisis.
