Search The PM.0001 short rotation paulownia tree cultivation methodology version 1.0 was officially published on June 3, 2024. We published an updated and improved version of the methodology (v1.2) on April 1st, 2026. Please view the methodology changes in the change log available on page 2. # Short rotation paulownia tree cultivation Explore our methodology for harnessing the power of Paulownia trees in short-rotation cultivations. The fast-growing Paulownia trees are ideal for creating bio-based construction materials and long-lasting durable products, effectively sequestering CO2 for several decades.  ![N (9)](https://proba.earth/hubfs/N%20(9).png "N (9)") ## Short rotation paulownia tree cultivation Methodology ID: PM.0001 Date of Issue: June 3, 2024 Developer: Proba World BV [Download version 1.1](https://proba.earth/hubfs/Methodologies/PM.0001_Methodology_Short_rotation_Paulownia_Tree_Cultivation_v1.0.pdf?hsLang=en) This methodology provides a framework for measuring and monitoring the carbon sequestration of Paulownia plantations. Leveraging scientific research and standards from [IPCC](https://www.ipcc.ch/), [CDM](https://cdm.unfccc.int/), [FAO](https://www.fao.org/home/en/), and [GHG Protocol](https://ghgprotocol.org/), we outline each step taken, from the establishment of the plantation until the delivery of the wood that will be processed and used in construction.
