Net-negative insulation material - Finland

25 € / CORC

Description info

CORCs are available for purchase from issuances until 2022. New issuances will not be made due to the revised Puro Standard requirements for the carbon storage durability. Read more here.

Ekovilla offers carbon net-negative cellulose fibre insulation (CFI) made from renewable natural resources. One tonne of Ekovilla’s CFI removes 1,11 tonnes of CO2 eq. from the atmosphere into long-term storage in the product. The insulation is suitable for both new construction and renovation projects and it is used in 10,000 buildings annually. Once installed, CO2 is stored in durable building structures for a minimum of 50 years. It is industrial carbon removal to help corporations achieve their climate targets and take proactive steps towards carbon net zero.

How it works

Growing trees capture carbon which is then stored in bio-based construction materials. Sustainably grown wood is used for producing newspapers, which are recycled and used as the main ingredient for manufacturing Ekovilla's cellulose fibre insulation (CFI).

Once CFI is installed, CO2 is locked and stored in buildings for decades.

Examples of usage info

Public buildings, such as schools, industrial and residential buildings, townhouses and summer cabins.

Co-benefits info CORCs only quantify the net-removal and storage of emissions, not reduced or avoided emissions, increased biodiversity or other positive benefits. Here are co-benefits self-reported by the removal supplier.

  1. Healty indoor air: The indoor air humidity is kept at an optimal level with Ekovilla breathing cellulose insulation.
  2. Reduce waste: Cellulose insulation helps reduce discarded paper that according to IPCC (p.17) is emitted  back to the atmosphere in 2 years. With Ekovilla insulation that CO2 embodied in the waste paper is locked-up to a storage for the life time of the building.
  3. Avoid emissions: Use of  our product can displace use of other insulation materials like polystyrene (EPS) or mineral wool. At best nearly 7 tons of CO2 emissions may be transformed to 1 ton of CO2 removal.
  4. Green jobs: manufacturing cellulose insulation creates green jobs.

Economic acceleration impact info

The extra income from allows Ekovilla to develop it’s concept of using local waste paper and board materials further, converting it to insulation and other net-negative products. For example, Ekovilla slab products were also turned to net-negative by adopting the same methods and concept, which are used for blown wool products – this development project was partly financed by using the income from CORC sales. Also, with CORC revenue, the company is ramping up a waste-free packing & installation process, in which they will use metal containers instead of plastic bag packaging. Containers are packed directly in the production process and refilled after every installation.

Climate Impact

1 tonne of Ekovilla’s cellulose fibre insulation (CFI) removes  1,11 tonnes of CO2 eq. from the atmosphere into long-term storage in the product. Life-Cycle Assessment made by VTT followed the methodology described in ISO 14044 and ISO 14064 standards where applicable.

Additional information

Ekovilla's cellulose fiber insulation carbon removal project was reviewed by Carbon Plan, a non-profit research organization that analyzes carbon removal opportunities based on the best available science and data. Their report and comments are publicly available for carbon removal mechanism, volume, negativity, permanence, cost, additionality and specificity, here (search for Ekovilla)

Audit Information

Compliance to methodology requirements is done by an independent assessor. Their auditor visits the production facility, validates the accuracy of data, including the carbon net-negativity evidence presented in a Lifecycle Assessment (LCA) or Environmental Product Declaration (EPD) report, and issues an audit statement.
