Helping enterprises explain their GX efforts

GXTI shows how various GX technologies can be categorized

The Green Transformation Technologies Inventory (GXTI), released by the Japan Patent Office (JPO), helps enterprises and others objectively explain their green transformation (GX) efforts. GXTI shows a way to categorize GX technologies and how to search for patent documents pertinent to the respective category of GX technology. In line with the recommendations of the Task Force on Climate-related Financial Disclosures (TCFD), companies are required to objectively demonstrate how the value they create (products and services) can contribute to solving climate change issues. GXTI can be used for such disclosure of information.

What is GXTI?
GX now underway is shifting the economic, social, and industrial structures that have depended on fossil fuels since the Industrial Revolution to structures driven by clean energy. GXTI shows how various GX technologies can be categorized, and how patent documents related to each category of GX technology can be searched. It provides a bird’s-eye view of GX technologies through five large technology categories (Level 1) and four transversal perspectives to enable formation of common understanding of GX technology.

The technologies inventory was developed after two rounds of discussions by a panel comprising six external experts with in-depth knowledge of GX technology and released as GXTI in June 2022.

Anyone Can Search Patent Documents Same Way, Disclose Information Objectively GXTI has a hierarchical structure with the large category of Level 1, the medium category of Level 2, which divides the large category, and the small category of Level 3, which further divides the medium category. A patent search formula is provided for each small category of technology. The patent search formulae were created using the extensive knowledge of JPO patent examiners in each field.

GXTI is characterized by its published patent search formulae, which allow anyone to conduct a search under the same conditions, and by its formulae based on the International Patent Classification (IPC), which allows searches of patent documents from all over the world. With GXTI, anyone can analyse the patent information available worldwide and determine one’s technical position and potential for GX technology. This would help to objectively demonstrate how the value created (products and services) by companies can contribute to climate change issues.
