Green CO2 aims to obtain Carbon Footprint of Product (CFP) certification for the CO₂ produced in this project. Green CO2 will continue to meet the needs of a wide range of industrial sectors through the stable supply of high-quality CO₂ products.. This joint venture is an initiative that creates added value through the effective use of existing resources and contributes to the development of environmentally responsible industries. Through this project, Nippon Sanso Holdings Group will establish a resource-circulating CO₂ supply chain in Thailand and contribute to the realization of a carbon-neutral society on a global scale.
