What is construction stored carbon?

Construction stored carbon refers to biogenic carbon (CO₂ absorbed by plants) that is locked into long-life building materials. When plant fibres are embedded in concrete or other mineral binders, the carbon they contain is stored for the lifetime of the building—typically 35+ years.

How is carbon storage verified?

Carbon storage is verified at the project level by independent certification bodies. This involves documenting the full supply chain from biomass cultivation through construction, calculating stored carbon quantities, and demonstrating long-term storage commitment.

Does Econcreed issue carbon credits?

No. Econcreed provides the technology and supply chain registration that enables carbon certification, but we do not issue carbon credits ourselves. Credits are issued only by accredited certification bodies after project-level verification.

What certification frameworks does Econcreed support?

Econcreed's chain registration approach is designed to be compatible with ONCRA, Climate Cleanup Protocol, and SNK frameworks. These are established standards for construction stored carbon certification in Europe.

How much carbon can be stored per cubic metre?

Carbon storage varies by product type and fibre content. Specific figures are project-dependent and verified during certification. We do not publish generalised carbon storage claims—all figures are validated at the project level.

Construction Stored Carbon — explained

Understanding how biogenic carbon storage works in construction, and Econcreed's specific role in enabling certified carbon storage.

Key Definitions

Terminology aligned with Climate Cleanup Protocol and ONCRA standards.

Biogenic Carbon

Carbon absorbed from the atmosphere by plants via photosynthesis. This carbon is stored in plant biomass during growth.

Construction Stored Carbon

Biogenic carbon stored in long-life construction products. Expressed in tonnes of CO₂ equivalent and verified at the project level.

Net Carbon Removal Benefit

Calculated at project level, requires baseline comparison and is verified by independent certification bodies.

Carbon storage is enabled by our treated plant fibres and verified through supply chain registration.

Econcreed's Role

Clear boundaries between technology provision and certification.
