Yachiyo Engineering's Green Power Certificate Project Receives Recognition

Yachiyo Engineering Co., Ltd., located in Taito, Tokyo, has recently been awarded the Excellence Award at the 26th Green Purchasing Awards, held by the Green Purchasing Network (GPN) on December 3, 2025. This prestigious award recognizes organizations that contribute significantly to promoting environmentally friendly purchasing practices. It emphasizes the importance of choosing products and services that aim to minimize environmental impact and foster social responsibility.

The Green Power Certificate initiative, launched by Yachiyo Engineering, is a remarkable effort dedicated to creating a sustainable local economy. The company issues green power certificates derived from renewable energy sources, specifically biomass energy generated at waste disposal facilities across ten municipalities nationwide. These certificates are then prioritized for sale to local businesses, allowing them to support environmental conservation in their communities.

Features of the Initiative

1. Realizing Local Economic Circulation
The project involves issuing green power certificates that encapsulate the environmental values from renewable energy. The funds collected from purchasing businesses are directed to local municipalities, which utilize them for the maintenance of waste facilities and tackle regional issues. This practice effectively promotes local economic circulation and utilizes environmental resources originating within the community.

2. Promoting Regional Decarbonization
In the pursuit of decarbonization, businesses must leverage certificates and credits. The collaboration between local governments and companies facilitates practical decarbonization efforts through the use of green power certificates. This approach allows companies to reduce CO₂ emissions without massive capital investments, making it feasible for businesses with constraints such as construction timelines or challenges related to solar power generation due to snowfall.

3. Effective Utilization of Waste Resources
Waste is not merely refuse; it can be an economic asset. The participating waste facilities repurpose waste into biomass energy, generating power. By recognizing the potential economic value in waste, the project contributes to sustainable societal development through effective resource management.

Application Title and Evaluation Points
