Paulownia-Based Agroforestry Systems

Carbon Sequestration Potential and Investment Returns — A Comprehensive Analysis

By Dirk Roethig, CEO, VERDANTIS Impact Capital — April 2026

Abstract

This whitepaper presents a comprehensive, evidence-based analysis of Paulownia-based agroforestry systems as a climate-aligned investment opportunity. Drawing on peer-reviewed research, we demonstrate that hybrid Paulownia plantations can sequester 20-35 tonnes of CO2 per hectare per year under favorable conditions.

Key Findings

Carbon Sequestration: Peer-reviewed studies (Icka et al., 2024; Magar et al., 2018) consistently demonstrate sequestration rates of 15-35 t CO2/ha/year.
Investment Returns: The diversified agroforestry model achieves an Internal Rate of Return (IRR) of 14-20% with payback periods of 3-6 years.
Carbon Credit Revenue: At EUR 18-26/tCO2e (current ARR market prices), carbon revenue contributes EUR 400-700/ha/year.
EU Regulatory Alignment: Qualifies under EU Taxonomy Activity 1.1 (Afforestation) and SFDR Article 9.

Economic Analysis

Three investment scenarios over a 10-year rotation:

Scenario	Revenue Sources	IRR	NPV (EUR/ha)	Payback
Conservative	Timber only	8.5%	12,000	7-8 years
Base Case	Timber + Carbon	14.2%	28,000	5-6 years
Optimistic	Full Agroforestry	19.8%	45,000	3-4 years

Carbon Market Outlook

The voluntary carbon market is projected to grow from EUR 3 billion (2026) to EUR 15 billion by 2035. High-quality ARR credits traded at USD 26/tCO2e in December 2025, representing an 86% year-over-year increase.

EU Regulatory Framework

The 2026 revisions to the EU Climate Delegated Act simplify forestry screening criteria. Paulownia projects can certify under Verra VCS, Gold Standard, and the new EU Carbon Removal Certification Framework (CRCF).

Risk Assessment

Primary risks (frost, Phytophthora, price volatility) are mitigable through hybrid selection, geographic diversification, and revenue diversification. Paulownia is not on the EU Invasive Alien Species list.
