Green Carbon Inc.

This project builds upon the results of a preliminary demonstration conducted in Toyota City this fiscal year, and aims to expand the demonstration fields nationwide, with the future goal of national deployment that contributes to improving farmers' income and reducing environmental impact across Japan. Furthermore, to promote this project, Toyota City's corporate hometown tax donation system (*2) will be utilized to widely solicit companies that support this initiative.
