A case study on Fuji Nihon Co., Ltd., which uses renewable energy derived from sugarcane, has been published. The company’s integrated report also features green power certificates from Japan Natural Energy as part of its environmental (ESG) activities.
Japan Natural Energy Co., Ltd. was founded on November 1, 2000, and the first business day of November is the founding anniversary. November 2, 2026 (Monday) will be a closed day. Normal business operations will resume on Wednesday, November 4.
Japan Natural Energy Co., Ltd. will exhibit at the 1st International Thermal Energy Exhibition – I‑TEX JAPAN – held in September. The exhibition is part of Smart Energy Week and focuses on decarbonizing heat. The booth will accept inquiries about green heat certificates and green electricity certificates, and prior registration is required.
As part of the "Everyone's CO2 Reduction Project 2026" hosted by Nihon Sōken Co., Ltd., a program called "Eco Label Hunter 1.5°C Operation" is underway, where students in grades 1-6 investigate eco-labels at home and in stores and can record their findings on a dedicated website. The results can win prizes, and can be downloaded from the My Page for use in independent research or inquiry-based learning. The application period runs from June 1, 2026 to October 13, 2026.
Yokohama City is working to expand the spread of renewable energy in pursuit of decarbonization by 2050, and has signed cooperation agreements with 18 municipalities.

Due to a system outage, our website was temporarily inaccessible, but it has now been restored to normal operation. We sincerely apologize for the significant inconvenience and concern caused to all users. Thank you for your continued support.
Japan Natural Energy Co., Ltd. has renewed the design of its Green Power Certificates and Heat Certificates to celebrate its 25th anniversary. The new design incorporates a modern and refined aesthetic; the old design will remain in use until December 2025, and from January 2026 onward the new design will be applied. The online certificate purchase service "GreenPokke" will also switch to the new design at the same time.
Our Green Pokke service will be suspended from around 5 p.m. on December 26, 2025, until around 2 p.m. on January 5, 2026, due to the year‑end and New Year holidays. We apologize for any inconvenience to our users and ask for your understanding. The service will resume around 1 p.m. on January 5, 2026.
On November 1, 2025, in celebration of our 25th anniversary, we renewed our website. With expanded content and improved design and layout, it is now more user‑friendly. The new URL is http://natural-e.co.jp/, and the old URL will automatically redirect.
TBS will broadcast the Tokyo 2025 World Athletics Championships and announced efforts to achieve net zero CO2 emissions. Details can be checked on the official website.
