Why forest owners only earn money once – and how greenkeeper is changing that

The forest produces clean water, fresh air, CO₂ storage, habitat for hundreds of species. Ecosystem services that benefit society daily — and for which not a single euro flows to the forest owner. Harvesting timber or nothing: That is the economic reality for the majority of German private forest owners. greenkeeper was founded to change exactly that. In our webinar, Paul Pletsch and co-founder Leonhard Vidal explained how the remuneration model works, what forest owners have to deliver for it — and why getting started involves no financial risk. This article summarizes the essential points.

The fundamental problem: A market that ignores ecosystem services

The traditional timber market only remunerates what is physically removed from the forest. Everything else — CO₂ sequestration, water storage, biodiversity, climate stabilization — remains economically invisible. This has direct consequences: Forest owners who want to convert their stands ecologically — more mixed forest, more deadwood, more structural diversity — bear the costs of these measures themselves without being compensated. Anyone who girdles trees instead of harvesting loses revenue. Anyone who leaves deadwood standing foregoes wood chips. Anyone who frees up future trees instead of clear-felling entire stands performs worse economically in the short term. This is not a question of willingness, but of economic viability. And this is precisely where greenkeeper steps in.

What the CO₂ market has to do with it

For years, mechanisms have existed to economically evaluate ecosystem services: CO₂ certificates. A forest that stores CO₂ can certify and trade this storage capacity — theoretically. In practice, the so-called Voluntary Carbon Market (VCM) has so far been a problem, not a solution. The most famous case: the Verra scandal (2022/2023). One of the world's largest certification registries issued 94.9 million rainforest certificates — even though only 5.5 million tons of CO₂ were actually avoided in reality. The rest: zombie certificates (certificates without real ecological equivalent) and double spending (the same certificate sold multiple times). The result was a massive loss of trust in CO₂ offsetting as an instrument. For forest owners, it meant: The market that could have compensated their services was structurally broken. What was missing: Technology that measures CO₂ storage independently, precisely, and tamper-proof. And a system that bundles all process steps — from measurement to certificate issuance — in one hand, without intermediaries, without possibility of manipulation. This is the system greenkeeper built.

How greenkeeper measures CO₂ storage: ±5% accuracy

The foundation of any remuneration is reliable measurement. greenkeeper uses the European Space Agency's (ESA) Sentinel satellites for this purpose — a publicly accessible, independent database providing new images every 4 days. From the satellite data, the biomass of each forest project is calculated — i.e., the amount of organic material the forest has built up and thus binds CO₂. The measurement accuracy is ±5%. For comparison: Traditional forest inventory, where foresters walk through the forest with a relascope and take samples, achieves an accuracy of about ±30%. Satellite-based measurement is thus six times more precise — and significantly more tamper-resistant because it relies on external, state data. The system is supplemented by drone flights with a resolution of up to 10 × 10 cm. This allows deadwood, water holes, or early signs of ash dieback and beetle infestation in the canopy to be localized exactly — long before they would be visible to the naked eye. Monitoring runs 365 days a year: Every 6 hours, fire sources are automatically checked, and every 4 days, new biomass data arrives. If a significant change occurs, token sales for the affected project are automatically paused.

The remuneration model: What forest owners specifically receive

Requirements

• Minimum area: 10 hectares — as an individual plot or as a joint area via forest management associations (FMGs) or forest owner associations (WBVs)
• Proof of ownership: Land register excerpt or lease agreement with a term exceeding the 10-year project contract duration
• Willingness to convert the forest: Retention of deadwood, underplanting, development of edge structures, maintenance according to an agreed project plan

What is not required: Prior knowledge of the CO₂ market, own technology, or capital.

What is measured and remunerated

greenkeeper does not calculate the total biomass, but the roundwood ratio — i.e., the share that can be used as high-quality construction timber. In Germany, this ratio is approx. 55% of the total quantity. The reason is both ecological and economic: Timber used in roof trusses, furniture, or facades binds its CO₂ for another 80 years or longer. Accounting for this extended storage effect results in a total CO₂ binding period of up to 150 years — a significantly stronger ecological argument than mere forest storage.

The figures

• Market price per ton of CO₂: approx. €55 – €75
• Forest owner share: 20% of net proceeds
• Minimum guarantee: €12.50 / ton of CO₂

To put this into context: The Gut Conow project achieved a storage capacity of 20,170 tons of CO₂ in 2024, with an annual increase of approx. 1,300 tons. At a minimum price of €12.50, this corresponds to a compensation of over €250,000 per year for this project alone — without a single ton of timber having to be felled.

Payout: Security through staggering

The premium is not paid out all at once, but staggered:

• 50% flows in the year of certificate sale
• 50% is continuously paid out over the entire contract term (10 years)

There is a specific reason for this: If a damage event occurs — storm, bark beetle, fire — the forest owner still has secured income for reforestation. Ongoing payout is not a financial product, but a safeguard against loss of revenue in calamity years. In the event of a total loss, the following additionally applies: greenkeeper grants a 100% replacement guarantee for issued CO₂ certificates from its own buffers. The buyer of a certificate bears no risk of default.

What greenkeeper costs: exactly €0

This is the point that regularly causes surprise in conversations with forest owners. Comparable certification providers like Gold Standard or Verra charge upfront costs of €15,000 to €100,000 for expert opinions, audit reports, and registration — to be borne by the forest owner before any payout, without any guarantee of certification. With greenkeeper, there is no onboarding fee, no advance payment, no financial risk. greenkeeper covers all project development costs — satellite monitoring, on-site audits by our foresters, blockchain registration — and finances itself exclusively through its own share of proceeds after the sale. If you are not sure whether your land is suitable: greenkeeper offers a free area analysis before purchase or entry to evaluate the CO₂ potential of a stand — even for areas with current beetle infestation or poor starting stands.

What this means for investors

Whoever acquires greenfee Tokens does not finance abstract "CO₂ compensation". They specifically finance:

• The forest conversion measures that a forest owner could not implement without external compensation
• The loss of yield that occurs when a tree is girdled instead of harvested
• The technology infrastructure that makes each of these steps measurable, traceable, and tamper-proof

Every token is assigned to a verified CO₂ certificate. If used for compensation, it is irrevocably retired on the blockchain — including a digital cancellation confirmation, presentable for auditors and CSRD reporting. The connection between forest owner and investor is thus not a letter of intent, but a technically anchored, auditable chain: from satellite measurement through blockchain registration to certificate issuance — in one system, without intermediaries, without zombie certificates.

Conclusion

The forest provides more than the timber market pays for. This is no new realization — but until now, the infrastructure to make this service measurable, tradable, and trustworthy was lacking. greenkeeper is this infrastructure: for forest owners who want to convert their stands to be climate-resilient without paying for it. And for investors who want to know where their money goes in the forest — and why it stays there.
