What Green Carbon does
Green Carbon Co., Ltd. (Green Carbon株式会社) is a Tokyo-based environmental technology company founded in December 2019 that develops, certifies, and sells nature-based carbon credits generated primarily from agricultural and forestry projects across Asia-Pacific. Its core methodology is Alternate Wetting and Drying (AWD) rice cultivation, which reduces methane emissions from paddies by approximately 77% while maintaining yields and lowering water use, and is being deployed at scale across Vietnam (~116,000 hectares in An Giang), Cambodia, Thailand, and the Philippines. The company is diversifying into biochar pyrolysis (50 TPD of combined capacity in India targeting ~18,000 tonnes of CDR credits annually), mangrove reforestation, forest conservation, and livestock methane reduction, and holds the first and largest J-Credit certification for rice paddies in Japan alongside the world's first Verra VM0051 rice paddy listing.
The underlying technology platform is Agreen, a digital MRV (Measurement, Reporting, Verification) system that integrates credit registration, application, and sales, and combines farmer-level structured data with JAXA DAICHI-2 satellite imagery for national-scale agricultural emission monitoring. Green Carbon monetizes credits through direct corporate sales to 600+ enterprise partners (including FamilyMart, Kanematsu, Osaka Gas, Norinchukin, Mitsui Sumitomo Insurance, and Nippon Koei), government JCM bilateral transactions across multiple ASEAN countries, ESG/GX consulting engagements, and channel partnerships such as the Sumitomo Forestry Morikachi platform. Go-to-market is sales-led and event-driven, anchored by the annual Carbon Credits Journal Forum in Tokyo, supplemented by co-hosted government seminars, international conference participation, and a community-led model engaging farmer cooperatives and universities (VNUA, BRIN, SEARCA) at the supply base.
