Toshiba Shifts to 100% Renewable Energy for Key Semiconductor Fabs in Japan
Published: 7.31.2025
Toshiba Electronic Devices & Storage Corporation has announced a major milestone in its sustainability roadmap: both its Kaga (Ishikawa) and Himeji (Hyogo) semiconductor production facilities are now sourcing electricity entirely from off-site solar power purchase agreements (PPAs).
This transition is a step forward in Toshiba’s efforts to reduce its environmental impact across its global manufacturing operations. According to company reports:
The Kaga facility has secured approximately 27 GWh of renewable energy annually, achieving full renewable consumption by June 2025. This shift is expected to reduce carbon emissions by around 13,000 metric tons per year.
The Himeji site now utilizes approximately 6.2 GWh of solar-sourced electricity annually, resulting in estimated emissions savings of 2,500 metric tons.
The company’s renewable energy sourcing aligns with its broader commitment to achieving net-zero greenhouse gas emissions from manufacturing by 2030.
As global demand for semiconductors continues to grow—especially in energy-sensitive sectors such as automotive, industrial, and infrastructure—energy sourcing decisions are increasingly central to long-term resilience and sustainability.
This development reflects a broader industry trend, as semiconductor manufacturers around the world move to decarbonize their operations, manage energy costs, and meet corporate ESG goals.
