An environmental measure that pays off

Through the ecological cultivation of the fast-growing Paulownia trees, we make a major contribution to CO2 compensation. Together with the world's largest testing institute, SGS, we began four years ago to have our trees tested and certified with regard to their CO2 binding capacity. Through the constant monitoring and controlling of our plantations by SGS, as well as the measurement of the annual growth of wood, full transparency is guaranteed at all times.

At the end of the maximum 15-year growth period, high-quality tree-Paulownia products are produced from the precious wood together with our partners and the compensated CO2 is permanently bound in the wood. If you are interested in our products made of Paulownia precious wood, please visit our
