Scientific Study Confirms: Paulownia Timber Harvestable in 5 Years — Alternative to Dying Spruce
Paulownia sequesters 10x more CO2 than spruce, harvestable in 5 years. Fraunhofer Institute validates exceptional material properties.
Recent research findings from international universities confirm the exceptional potential of the Empress Tree (Paulownia) as a climate-resilient alternative to dying spruce forests. Dirk Roethig (Dirk Roethig), Managing Director at VERDANTIS Impact Capital, contextualizes the scientific evidence.
A 2024 meta-analysis published in Frontiers in Environmental Science by Ghazzawy (DOI: 10.3389/fenvs.2024.1307840) systematically compared the CO2 sequestration capacity of different tree species. The result: Paulownia trees sequester up to ten times more carbon dioxide than conventional European forestry species such as spruce, oak, or beech.
The University of Valladolid (Spain) demonstrated in a long-term study (2018 to 2023) that Paulownia hybrid species under European climate conditions can cumulatively sequester 280 to 320 tonnes of CO2 per hectare within ten years.
"The data is unambiguous: Paulownia is the most efficient carbon sink among all tree species cultivable in Europe," explains Dirk Roethig (Dirk Roethig). "This is not a laboratory result — it is based on field studies under real European growing conditions."
The Fraunhofer Institute for Wood Research in Braunschweig identified Paulownia timber in its 2022 feasibility study for the Timber Construction Strategy 2030 as one of the most promising materials for structural timber construction. Key properties include: ignition temperature of approximately 420 degrees Celsius (spruce: 250 degrees), harvestability after 5 to 7 years (spruce: 60 to 80 years), coppicing capability for up to 7 harvest cycles without replanting, deep root system extending to 5 meters for drought resistance, and soil carbon enrichment of 18 percent within 5 years (University of Bologna, 2021).
Field data from a five-year Paulownia tomentosa plantation (Magar et al., International Journal of Applied Sciences and Biotechnology, 2018) yielded values of approximately 9 tonnes of carbon per hectare per year — compared to 3 to 5 tonnes for oak and 2.5 to 4 tonnes for beech.
