There is an initiative called GX (Green Transformation) started by the Japanese government against the climate change problem. The Japanese Patent Office has released the GXTI (Green Transformation Technologies Inventory), a technology classification for technologies related to GX. In this paper, trends in the number of patent applications for the Top 5 technologies related to GXTI were analyzed. In addition, the technology diversity of the Top 5 was analyzed. For diversity analysis, taxonomic indices applying the concept of biodiversity were discussed. As a result of introducing this index, it has become possible to grasp the ratio of research and development according to the level of technological integration.
