Biochar meets concrete: engineered carbon removal you can trust
What if carbon removal wasn’t just something you bought
— but something you could see and touch?
Unlike conventional Biochar Carbon Removal (BCR) projects that store biochar in soil, we chemically embed it into durable construction materials like concrete and turn buildings into effective, measurable carbon sinks.
The result: permanent, high-integrity carbon storage that transforms the built environment from a major emitter to a climate solution.

One Building today.
A carbon-storing city tomorrow.
Proven
70 t CO₂ stored in concrete
Equivalent to a single 5-storey building
or 16 laps around the Earth in an SUV
Now Scaling
250,000 t CO₂ by 2030
Enough to turn an entire city into a carbon sink
or 1.400 laps around the Earth in an SUV
Why choose ecoLocked Carbon Credits?
Permanent carbon removal, verified and ready for your net-zero goals
Carbon removal only works if the carbon is securely stored. We offer credits that our buyers can rely on. Therefore, permanence, traceability, and low risk of reversal are essential for high-quality credits.
Here is where ecoLocked makes the difference.
We turn concrete into a carbon sink—making removal tangible, traceable, and real.
Whenever ecoLocked Materials® are used in third-party construction projects, durable carbon removal takes place and high-quality credits are issued.
Use verified credits to close the gap to your net-zero roadmap and signal sustainability leadership to your stakeholders.
Long-Term Durability
Carbon embedded in concrete is locked away for centuries—with minimal risk of leakage or reversal.
Scalable Supply
By integrating biochar into high-volume construction materials, we unlock a new industrial pathway for carbon storage.
Cost-Effective
ecoLocked credits are among the most cost-competitive in the concrete and durable removals segment.
Fully Tracable & Verified
Each credit is linked to a physical storage location and tracked by rigorous MRV partners.
Join us in building the biggest carbon sink on Earth!
We must remove 10–20 Gt of CO₂ per year to meet our climate goals.
But today’s carbon sinks are limited.
Concrete is the 2nd most used material on Earth — and demand is doubling in the next 40 years.
With ecoLocked, every cubic meter becomes a permanent carbon sink — embedded directly into the infrastructure the world is already building.
This is carbon removal that grows with the built environment.

Generate carbon credits from your own real estate assets
ecoLocked enables you to store carbon in your own real estate projects by integrating our CO2-negative concrete admixtures.
Choose how to account for the carbon removal:
Insetting: Treat the carbon removal as an internal emissions reduction, to compensate for emissions in your company. (see our FAQ on how to use the credits in sustainability reporting under CSRD and SBTi).
A carbon credit is issued and then immediately retired on behalf of your company.Carbon markets: Alternatively, you obtain third-party verified carbon removal credits to trade on the voluntary carbon market.
Regardless of your strategy, ecoLocked provides full MRV support to ensure traceability and third-party validation.
Ideal for:
- Corporate real estate (e.g. offices, data centers, supermarkets, warehouses, …)
- Real estate developers & Construction Firms
- Green Real Estate Investors & Infrastructure Funds
