Durable CDR Credits
From CO₂ to carbonates
Carbonaide’s innovative technology enables a carbonation process where calcium ions from the cement dissolves naturally, mineralizing the CO₂ as carbonate minerals. Studies confirm that CO₂ chemically bound in concrete remains stored for >1000 years.
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 science-backed credits, adhering to the strictest verification and certification standards.
- Integrate durable CDR credits in your climate strategy by following the like-for-like principle – neutralizing fossil emissions only with durable CDR.
- Make a credible climate contribution claim not tied to the exact size of emissions.
- Help scale the market – building up large-scale volumes of durable CDR in 2040 or 2050 requires investment in different technologies today.
- Be a catalyst for building new mineralization locations by committing to purchase future credits.
- Become an early buyer of durable CDR to ensure future supply, stronger ESG credibility and readiness for upcoming regulations.
Global impact
The concrete industry is considered one of the most difficult to decarbonize, responsible for 8% of global CO₂ emissions. Concrete is the second most consumed material on Earth after water with demand expected to double by 2050.
Construction materials could store over 16 Gigatonnes of CO₂ per year, with concrete holding the biggest potential – 80% of the total CO₂ storage capacity.
Purchase carbon credits
If you are interested in integrating our durable CDR credits in your corporate climate and sustainability strategies, please fill out the contact form below. We have two facilities starting CDR activities in 2026 and credit vintages 2026-2030 are available. In addition, we offer future credits, where pre-purchase commitments for new factory locations act as a catalyst for signing new concrete manufacturers adopting our mineralization technology.
