Epson to Transition to 100% Renewable Electricity at All Sites in Nagano Prefecture

Press release from the issuing company

Epson to use CO?-free Shinshu Green Electricity produced in Nagano 

Tokyo, Japan – Seiko Epson Corporation will transition to 100% renewable electricity at all Epson sites1 in Nagano prefecture from April 1 by expanding the use of CO2-free Shinshu Green Electricity produced locally in Nagano Prefecture using Nagano Prefectural hydroelectric power.

In April 2020, Epson began using Shinshu Green Electricity procured from Chubu Electric Power Miraiz Company, Inc. at its Head Office in Suwa and at two large sites in Shiojiri: the Hirooka Office, where the majority of printer development work is conducted, and the Shiojiri Plant, a watch development and production site. By expanding the use of Shinshu Green Electricity to its other sites in Nagano Prefecture, Epson will have transitioned to 100% renewable energy at all its 13 sites1 within the prefecture. As announced on March 16, Epson's goal is to meet all the Epson Group's power needs with 100% renewable electricity in 2023. This represents one step forward toward that goal.

By specifying the procurement of renewable electricity generated in Nagano Prefecture, Epson will not only reduce its own CO2 emissions but will also help to support actions aimed at expanding renewable electricity power sources in the prefecture and raise the renewable electricity supply rate.

As stated in Epson's Environmental Vision 2050, which was revised on March 18, 2021, Epson seeks to become carbon negative and underground resource2 free. Accordingly, the company will invest approximately 100 billion yen on decarbonization, resource recycling, and environmental technology development over the next ten years. Epson will concentrate most of its management resources on the development of products and services that help to reduce environmental impacts and that also contribute to reducing the environmental impacts of its customers.
