Idemitsu Combines Low-Carbon Energy and Carbon Credits for New Fuel Supply

Idemitsu Launches ICOF B5: A Step Toward Carbon Neutrality

Idemitsu Kosan Co., Ltd., based in Chiyoda, Tokyo, is set to contribute to carbon neutrality efforts with its new product, ICOF B5 (Idemitsu Carbon Offset Fuel B5 diesel), starting July 2025. This innovative fuel, made from low-carbon B5 diesel, is designed to offset emissions through carbon credits equivalent to the CO2 produced during its use. The launch of ICOF B5 will primarily service the geological survey operations of the Kurikoma South Project in Kurihara City, Miyagi Prefecture, marking a nationwide initial offering in this category.

Embracing Low-Carbon Solutions

ICOF B5 not only adheres to industry standards for fuel quality but also encompasses a ground-breaking approach to sustainability. By employing B5 diesel—which contains up to 5% bio-diesel derived from used cooking oils collected by Chida Cleaning in Miyagi—it promises to significantly reduce carbon emissions. This eco-friendly initiative is part of Idemitsu's broader commitment to sustainable practices, illustrated by its active engagement in geothermal resource development since the 1970s.

The ICOF B5 aims to offset approximately 95% of the CO2 emissions associated with its use by leveraging voluntary carbon credits purchased from certified projects, such as those from Verra, a recognized authority in carbon accounting. The issuance of a supply certificate detailing the CO2 offset amount ensures transparency and environmental accountability for all users.

The Kurikoma South Project

The Kurikoma South Project, a geothermal research initiative, benefits from government subsidies through the Independent Administrative Institution for Energy and Resources. Idemitsu aims to utilize this project as a catalyst for developing locally-sourced geothermal energy. As this initiative progresses, it underscores the importance of integrating green technologies within the construction and energy sectors to achieve a sustainable society.

Driving Carbon-Neutral Efforts Forward

Since launching its carbon credit-embedded fuel, ICOF, in July 2023 and B5 diesel in June 2024, Idemitsu has made strides in endorsing carbon-neutral practices across industries. The anticipated ICOF B5 further solidifies its position as a leader in promoting eco-friendly solutions to industrial challenges. Following its introduction, Idemitsu will actively support construction firms in their aspirations to meet carbon neutrality goals, positioning itself at the forefront of the industry's shift toward sustainability.

In conclusion, Idemitsu's ICOF B5 serves as a prime example of how innovative fuel solutions can effectively bridge the gap between energy needs and environmental preservation. As the world moves toward a greener future, the launch of products like ICOF B5 reveals the company's dedication to responsible energy options that not only benefit businesses but the planet as a whole.
