INSTITUTIONAL INTEGRITY
Explore our Methodology
Transparency is fundamental to credible climate action. This section provides access to the standards, verification, methodology, monitoring practices and documentation behind Carboreal’s carbon sequestration projects.
Independent Verification & Certification
Carboreal utilizes independent third-party verification to ensure that our carbon sequestration projects meet rigorous environmental standards. This section provides detailed documentation concerning Carboreal’s ISO 14064-2 certification and independent validation performed by Kiwa Certification Ltd.
ISO 14064-2:2019 Validation
- Organisation: Kiwa Certification Ltd
- Scope: Greenhouse gas quantification and reporting
- Issue Date: 2026-07-01
- Description: Verification of project-level carbon sequestration methodology and calculations.
Parcel-specific Carbon Calculation
Carboreal has developed a site-specific carbon sequestration model for Finnish afforestation projects. The methodology is built on scientific research into forest growth, soil emissions and land-use change, including data from the Natural Resources Institute Finland and other recognised Finnish research sources. The result is expressed in tonnes of carbon dioxide equivalent (tCO₂e).
Built-in conservatism
Most sequestration estimates rest on averages. Averages hide exactly what matters: the specific soil, species mix, and growing conditions of the parcel being sold. Carboreal replaces the averages with the site itself, resolves every uncertain input in the cautious direction, and then sets aside a risk buffer before anything is offered to customers.

Fraction for customers
The following factors affect the calculation result and originate from verified data sources, ensuring precise modelling.
Area
Why it matters
Calculations use the land area actually included in the project, obtained from sources like Peltolohkot.fi. The relevant figure is the area used for carbon sequestration rather than total property size.
What it tells us: How much land is included in the carbon-sequestration calculation.
Heat sum
Why it matters
This factor describes climatic growing conditions. Carboreal uses 50 years of gridded meteorological data from the Finnish Meteorological Institute. It represents long-term growing conditions, not short-term weather.
What it tells us: The climatic growth potential of the project location.
Fertility type
Why it matters
Describes the site’s capacity to support forest growth. Classification is determined according to principles used in Finnish forest-management recommendations, distinct from agricultural soil fertility.
What it tells us: How favourable the site is for tree growth.
Site type
Why it matters
Differentiates soil characteristics that influence forest growth and land-use emissions. Carboreal confirms whether soil is peat or mineral through parcel-level on-site assessments.
What it tells us: The soil type of the project parcel.
Local water balance
Why it matters
Influences growth and peat decomposition emissions. Methodology is based on definitions from the Natural Resources Institute Finland (Luke) to account for these local conditions.
What it tells us: Whether local water conditions support growth and influence soil emissions.
Initial land condition
Why it matters
Previous use affects the afforestation baseline. Carboreal distinguishes between grass-covered land and active cultivation based on Luke definitions.
What it tells us: What the land was used for before the Carboreal project.
Understanding the calculation result
Calculated tonnes
Created tonnes
Sold tonnes
The modelled expected sequestration result before the conservative buffer is applied.
The amount recorded after the applicable conservative adjustment.
The amount of climate units actually allocated or sold to customers.
Example: Jylkänmutka, Reisjärvi
Area: 7.59 ha
Heat sum: 1,138 C°vrk
Fertility type: grassland area
Site type: peat
Local water balance: (>40 cm)
Initial condition: cultivated land
Risk classification parameter
Calculated tonnes: 12,054
Tonnes created for the site: 10,125
This example illustrates how parcel-specific characteristics feed into the calculation. A different result may be produced by varied factors.
Example: Levävuori, Rautalampi
Area: 5.67 ha
Heat sum: 1,285 C°vrk
Fertility type: grassland area
Site type: mineral soil
Local water balance: (>40 cm)
Initial condition: grass
Risk classification parameter
Calculated tonnes: 6,381
Tonnes created for the site: 5,360
This example shows how different parcel characteristics lead to different results and do not apply to other projects.
Our Methodology
Carboreal calculates carbon sequestration based on rigorous scientific principles and ISO 14064-2 standards. Our approach ensures that every carbon unit represents a real, measurable, and permanent atmospheric removal.

Monitoring, Reporting & Verification
Carboreal maintains a rigorous Monitoring, Reporting, and Verification (MRV) framework to ensure the long-term integrity of our afforestation projects. Following implementation, projects are tracked according to documented procedures that define what is monitored—including sapling survival rates, biomass growth, and soil health—and the frequency of these audits. Monitoring is conducted by qualified foresters, with carbon sequestration estimates updated as new data is collected.
We identify and document project changes and reversal risks through systematic reporting. Customers receive detailed reports outlining the progress of their allocated carbon units. Independent third-party verification is carried out to validate these findings against international standards. Information/document required from Carboreal regarding specific localized audit schedules and auditor identities.
Project Traceability
We ensure that every customer understands exactly where their climate action takes place. Our goal is to connect each carbon unit to a specific, identifiable reforestation project in the Finnish landscape. Customer rights and ownership documentation are structured to ensure transparency, with details provided through documented unit allocations.

Location
Mikkeli, Finland

AREA SIZE
15 hectares
Kovalansuo is a multi-year afforestation project launched in 2021. The project is scheduled to be fully completed by autumn 2026.

Kovalansuo is a former peat production area with excellent potential for establishing a productive mixed forest and a long-term carbon sink. Due to the high acidity of the soil, natural forest regeneration is not possible without intervention. Ash treatment is used to reduce soil acidity and create more favourable conditions for forest growth. The land is owned by the City of Mikkeli, and the timber resources generated by the project will remain available for the benefit of the municipality and its residents.
Permanence & Risk Management
Permanence
Carboreal addresses the long-term nature of forest carbon sequestration through structured forest management and project durations designed for decades. Our permanence strategy covers long-term forest management and monitoring of reversal risks. We maintain a clear distinction between expected long-term carbon storage and any claims of absolute permanence, utilizing conservative calculation principles and buffer mechanisms if expected carbon sequestration is not achieved.
Additionality
Our projects create carbon sequestration that would not otherwise have occurred under the defined baseline. Additionality is demonstrated through site-specific land-use change and project intervention analysis. We document previous land use and the transition from marginal lands to productive forest ecosystems, ensuring that every sequestration unit represents a genuine climate gain. Information/document required from Carboreal for specific project validation.
Beyond Carbon
Beyond sequestration, Carboreal prioritizes ecosystem resilience through diverse afforestation and sustainable forest management. Our environmental safeguards cover biodiversity preservation, soil health, and water management. We monitor environmental risks to ensure afforestation projects contribute to broader ecosystem health. Measurable environmental claims are supported by project-specific data.
