1. About Green Liquid Nitrogen
Green Liquid Nitrogen achieves net-zero CO₂ emissions by offsetting the CO₂ generated during the production and transport of liquid oxygen, liquid nitrogen, and liquid argon through the use of electricity derived from renewable energy. To ensure the validity of CO₂ reduction calculation rules and operating procedures, certification has been obtained from a third -party certification body that references international standards.

Name: Green Liquid Nitrogen*
Applicable products: Liquid oxygen, liquid nitrogen, liquid argon (delivered by tank truck)
Sales launch: August 2025
Supply area: All regions of Japan except Hokkaido and Okinawa

Note: Although the applicable products are liquid oxygen, liquid nitrogen, and liquid argon, which are produced simultaneously through air separation, the product group is collectively referred to as “Green Liquid Nitrogen,” as nitrogen is the most abundan t component in air (about 78%) and accounts for the majority of demand.
