This investment opportunity supports a large-scale methane reduction project in Nghe An Province, Vietnam, focused on transforming rice cultivation practices through the adoption of the Alternate Wetting and Drying (AWD) methodology. The project targets implementation across approximately 62,000 hectares, with initial rollout already underway on 5,000 hectares, and is registered under the Gold Standard.
By transitioning from continuous flooding to AWD practices, the project is expected to reduce methane emissions by approximately 68%, generating an estimated 3.77 million tonnes of CO₂e emission reductions over a 10-year crediting period. Land access is secured through formal agreements with local farmer cooperatives and government entities. The investment opportunity seeks catalytic capital to scale farmer training, expand field implementation, and maximize high-integrity carbon credit generation from climate-smart agricultural practices.
The sponsor is a Japan-based carbon project developer with over a decade of experience delivering high-quality emission reduction projects across Asia, including under bilateral carbon cooperation frameworks. The organization has a strong track record in project design, monitoring, reporting, and verification (MRV), supported by institutional equity backing and a disciplined governance framework.
The sponsor leads all technical aspects of project development, including methodology application, baseline setting, and MRV, while partnering with leading academic and research institutions in Vietnam for technical validation and farmer capacity-building. Local government agencies and farmer cooperatives play a central role in land access, implementation support, and community engagement, ensuring alignment with national and regional development priorities. Key preparatory milestones—including baseline assessments, standard registration, pilot deployment, and independent climate impact review—have already been completed, positioning the project for rapid scale-up.
Calculus Carbon is acting as the strategic advisor for the structuring and capital raise of this methane reduction investment opportunity. Drawing on its expertise in carbon finance, climate-smart agriculture, and institutional investor engagement, the firm is supporting the design of flexible investment structures, including in-kind pre-financing repayable through carbon credits as well as cash-repayable debt instruments tailored to institutional climate capital.
In parallel, Calculus Carbon is strengthening the investment case by embedding ESG performance metrics, smallholder benefit-sharing mechanisms, and climate resilience co-benefits into the transaction narrative. The firm is also integrating risk mitigation measures—such as GIS-based site screening, robust QA/QC protocols, and digital monitoring infrastructure—to enhance transparency and investor confidence. Through this engagement, Calculus Carbon aims to mobilize catalytic capital into a scalable, high-integrity methane reduction solution that advances sustainable rice cultivation, rural livelihoods, and climate mitigation outcomes across Southeast Asia.
