Oiso Town
Cosmo Energy Group company Cosmo Oil Marketing Co., Ltd. (hereafter, “Cosmo Oil Marketing”) will begin supplying 100% renewable energy-derived electricity to 17 municipal facilities, including the town hall building and elementary and junior high schools, in Oiso Town, Kanagawa Prefecture, from April 1, 2025.
In 2023, Oiso Town declared itself a “Zero Carbon City” and has been working toward building a decarbonized society to promote sustainable urban development, with the goal of achieving net zero carbon dioxide (CO2) emissions by 2050.
To support the realization of this commitment, Cosmo Oil Marketing will offer its renewable energy-derived electricity plan, Cosmo Denki (Electricity) Business Green1, to Oiso Town facilities covered under the agreement. The plan provides renewable energy-derived electricity, endorsed by a non-fossil certificate with tracking information linked to a renewable energy source that falls under Japan’s Feed-in-Tariff (FIT) scheme, such as wind power generated by Cosmo Eco Power Co., Ltd., a Cosmo Energy Group company.

With the introduction of Cosmo Denki (Electricity) Business Green, annual electricity consumption of approximately 3.18 million kilowatt-hours (kWh) by 17 Oiso Town facilities will be converted to renewable energy-derived electricity, with an expected annual CO2 emissions reduction of around 1,500 tons2. This equates to approximately 73% of the CO2 emissions from the town's administrative operations.
Going forward, Cosmo Oil Marketing remains committed to supporting local governments and companies in reducing their environmental impact and will continue to undertake various initiatives toward the realization of a decarbonized society.
