Phase 2 Validation: The Scientific Foundation of the VPS
In February 2026, the University of Bonn's Institute for Crop Science and Resource Conservation, led by Professor Ralf Pude, published the complete Phase 2 validation study for the VERDANTIS Polyculture System (VPS). The study, conducted across six test sites at the bio innovation park Rheinland in North Rhine-Westphalia, represents the most comprehensive scientific assessment of Paulownia-based polyculture carbon sequestration conducted under European conditions to date.
Core Findings: Confirming the 30 tCO2/ha/year Benchmark
The Phase 2 study measured carbon sequestration across all VPS components over a 24-month period, incorporating full-season above-ground biomass sampling, deep root core analysis, and soil organic carbon profiling. The consolidated findings confirm:
- Above-ground biomass carbon: 14.2 tCO2/ha/year (trunk, branches, leaf mass)
- Below-ground root carbon: 8.7 tCO2/ha/year (root system to 4m depth)
- Soil organic carbon increment: 4.9 tCO2/ha/year (verified via paired comparison plots)
- Intercrop and reduced tillage carbon benefit: 2.4 tCO2/ha/year
- Total verified rate: 30.2 tCO2/ha/year (±1.8 tCO2, 95% confidence interval)
All measurements were conducted in accordance with ISO 14064-2:2019 and the EU CRCF QU.A.L.ITY quantification criteria. The study was independently reviewed by the bio innovation park Rheinland scientific advisory board before publication.
The Four-Pillar Revenue Model: Financial Validation
The Phase 2 study also validates the economic architecture of the VPS through empirical yield data from intercrop components. The VERDANTIS four-pillar revenue model generates income from:
- Carbon Credits: CRCF-certified removal credits at projected EUR 40–70/t, generating EUR 1,200–2,100/ha/year at the validated 30 tCO2 rate
- Timber Revenue: Paulownia timber is among Europe's most valuable hardwoods at EUR 800–1,400/m3 for premium grade. Harvest begins in Year 7, with coppice cycles every 5–7 years thereafter.
- Intercrop Yield: Phase 1 and Phase 2 intercrop sales (garlic, legumes, aloe vera, mint) generate EUR 3,500–6,000/ha/year in the establishment phase, partially offsetting capital costs.
- Ecosystem Services: Water retention, biodiversity credits, and potential payments under forthcoming EU ecosystem service frameworks provide a fourth revenue stream expected to become material post-2028.
Target IRR and SFDR Article 9 Alignment
Based on the validated carbon sequestration data and empirical intercrop yield figures, VERDANTIS projects a base-case target IRR exceeding 20% over a 10-year investment horizon. This projection incorporates:
- Conservative carbon credit pricing at EUR 45/t (versus the EUR 52–68 range of first CRCF-certified credits)
- No ecosystem service revenue in the base case
- Conservative timber price assumptions at EUR 900/m3
- Full CRCF certification costs and monitoring expenses included
The investment is structured as a SFDR Article 9 product — the highest EU sustainability classification — with the University of Bonn validation study forming the cornerstone of the fund's SFDR pre-contractual sustainability disclosures.
Scientific credibility is the non-negotiable foundation of the VERDANTIS investment thesis. The Uni Bonn Phase 2 validation closes the gap between theoretical projections and empirically verified performance — transforming a compelling concept into an institutionally investable asset.
CRCF Certification Pathway: Ready for Submission
With Phase 2 validation complete, VERDANTIS has submitted its methodology documentation to an accredited CRCF certification body for pre-assessment review. Upon adoption of the Carbon Farming Delegated Act in summer 2026, VERDANTIS will file its formal CRCF certification application, positioning the first portfolio projects to receive EU Carbon Removal Certification within 12–18 months of the Delegated Act's entry into force.
