– Targeting 450,000 tons of CO₂ reduction from rice paddies over five years –
Green Carbon Inc. (CEO: Jun Okita), a Japan-based developer of nature-based carbon credit projects, announced that its AWD (Alternate Wetting and Drying) project in Kamphaeng Phet Province, Thailand, has been officially listed under Thailand’s “Premium T-VER” scheme—an internationally aligned voluntary carbon credit program led by the Thailand Greenhouse Gas Management Organization (TGO).
This project aims to reduce methane emissions from rice cultivation through AWD techniques and is expected to generate approximately 450,000 tCO₂e over five years—making it the largest rice paddy project currently listed under Premium T-VER (as of May 2025, based on registered PDDs).

◆Background
Green Carbon develops nature-based carbon credit projects across Southeast Asia, including forest conservation, rice paddies, mangrove reforestation, enteric fermentation reduction in livestock, and biochar. With tailored approaches suited to local ecosystems and geographies, the company utilizes satellite data for precise site selection and monitoring, ensuring transparency and efficiency.
Thailand has become a key focus, with particular emphasis on AWD and biochar solutions. Agriculture is both a backbone of the Thai economy and a sector vulnerable to climate change. Green Carbon’s technology contributes to improving farming sustainability while driving a robust carbon market.
This AWD project introduces water-saving irrigation practices that reduce methane emissions, a potent greenhouse gas, while enhancing water-use efficiency and farmer incomes. A pilot has already been completed, and the project is now positioned for scale-up.
◆Project Overview
Location: Kamphaeng Phet Province, Thailand
Expected Annual GHG Reduction: 87,667 tCO₂e (cumulative ~450,000 tCO₂e)
Scheme: Premium T-VER (one of the largest rice paddy projects under the scheme as of May 2025)
Pilot completed: AWD implementation and MRV system already operational

◆Looking Ahead
In Thailand, methane emissions from rice cultivation have become a national climate priority. TGO’s Premium T-VER scheme, along with the Ministry of Agriculture and Cooperatives’ AWD expansion policies, is accelerating efforts to establish decarbonization models in agriculture.
Green Carbon plans to establish a local subsidiary in Thailand this year. Building on the success in Kamphaeng Phet, the company aims to launch eight new pilot projects in 2025 and expand operations across key agricultural provinces such as Phitsanulok, Ayutthaya, and Nakhon Ratchasima—targeting a cumulative implementation area of 1.5 million hectares.
The company is also actively forming partnerships with both public and private entities across Asia to develop one of the region’s largest rice-based decarbonization portfolios.
Partnership models include pre-investment schemes, offset credit purchase agreements, and co-branding for low-carbon rice exports. Interested companies are invited to connect with Green Carbon for collaboration.
〇Green Carbon’s Project Status in Thailand
※1：AWD (Alternate Wetting and Drying)
Alternate Wetting and Drying (AWD) is a method where the water level in the rice paddies is monitored, and water is alternated between flooding and natural drying every few days. Compared to continuous flooding, AWD reduces water usage and contributes to the conservation of water resources.
※2：Premium T-VER
This is a high-quality voluntary credit scheme promoted by the Thai Government, which issues carbon credits that companies and local authorities can use with confidence, following strict monitoring, screening and registration procedures in accordance with international standards.
