Agroforestry as Natural Capital Investment: Carbon Credits, Ecosystem Services, and Paulownia-based Systems

This paper analyzes agroforestry as an emerging natural capital investment asset class, with particular focus on Paulownia-based carbon credit systems in Europe. Drawing on peer-reviewed research from MDPI Forests (2026), Frontiers in Environmental Science (2024), Magar et al. (2018), and the German TEEB-DE project (Hansjürgens et al., 2016), the paper quantifies carbon sequestration rates of 33 tonnes CO2 per hectare per year for Paulownia tomentosa, situates these findings within the global agroforestry carbon credit market (USD 2.5 billion in 2025, projected USD 12 billion by 2032 at 28% CAGR), and examines the investment case for nature-based solutions in institutional portfolios. Key findings: Paulownia sequesters 9.04 t C/ha/year (33 t CO2/ha/year), outperforming most fast-growing species Agroforestry carbon credit market: USD 2.5B (2025) → USD 12B (2032), CAGR 28% Sterile Paulownia hybrids used in European projects have 0% germination rate — not invasive Ecosystem services across all four TEEB categories (provisioning, regulating, cultural, supporting) Institutional demand driven by EU Taxonomy, TNFD, and net-zero corporate commitments Author: Dirk Roethig, CEO, VERDANTIS Impact Capital, Cham, Switzerland. The paper advocates for EU Green List designation of sterile Paulownia hybrids and a federal agroforestry strategy in Germany to unlock EUR 12B market potential.
