Earth hacks, CGF, and H2O Retailing Collaborate to Implement a Decarbonization Practice Model in Takarazuka City: 'Dekabo Mikke!', a Parent-Child Participation Program Connecting Schools to Retail Stores

Earth hacks Co., Ltd. (Headquarters: Shibuya-ku, Tokyo; President: Sumito Sekine; hereinafter 'Earth hacks'), a consumer co-creation platform aiming to develop decarbonization-related products, services, and businesses based on consumer feedback, has collaborated with The Consumer Goods Forum (CGF) and H2O Retailing Corporation to implement 'Dekabo Mikke!', a parent-child participation decarbonization program in Takarazuka City, Hyogo Prefecture. The program connects classroom learning with home practices and retail store choices. This initiative is a 'social implementation' decarbonization model designed across local government, educational institutions, and retail sectors, based on insights gained from the 'Dekabo Mikke!' environmental learning program held at the Shiodome Summer School in August 2025. By connecting insights gained in educational settings to household actions and, ultimately, to actual product selection and purchasing behavior, the project aims to move beyond one-off learning and naturally root decarbonization in the daily lives of consumers. ■ Initiative Overview Taking place in Takarazuka City, Hyogo Prefecture, the initiative included visiting classes at Takarazuka Municipal Komyo Elementary School, the distribution of home learning materials, and retail store activities at Izumiya Shopping Center Obayashi. Through three steps—(1) Awareness at school, (2) Practice at home, and (3) Selection at the store—the initiative aimed to drive behavioral change toward decarbonization, starting with children. 【Initiative Details】 ＜STEP 1＞ School: Experiential Class 'Dekabo Mikke!' Rather than treating decarbonization and environmental issues as 'difficult topics,' an experiential class was held at Takarazuka Municipal Komyo Elementary School where students identified decarbonization efforts in everyday items and actions. With the cooperation of Panasonic Eco Technology Center Co., Ltd. (PETEC), the class included a workshop on finding recyclable parts through television disassembly and a quiz-based learning session on decarbonization actions that can be practiced at school and home. Through these experiences, the goal was for children to perceive decarbonization as a personal matter and gain insights that lead to future actions.
