The minute
- Verra approved the first carbon credits under its VM0051 methodology for improved rice production, generated by the Core Carbon Sustainable Rice Productions 01 project (VCS Project 3243) in Telangana, India.
- The project avoided over 210,000 tonnes of CO2 equivalent by replacing continuous flooding with alternate wetting and drying (AWD), a technique that reduces methane emissions from rice paddies.
- Thirteen additional projects using VM0051 are under development or validation across India, Brazil, Vietnam, Philippines, Indonesia, Thailand, Malaysia, Myanmar, and Madagascar.
Why it matters: Flooded rice cultivation is one of the largest sources of agricultural methane emissions worldwide. Until now, rice-sector projects had limited access to credible carbon crediting pathways. The approval of VM0051’s first credits signals that methodologies targeting rice methane can move from pilot to operational scale, potentially unlocking carbon finance for millions of smallholder farmers across Asia, Latin America, and Africa.
What the methodology actually rewards
VM0051 quantifies emission reductions from changes in water management, crop residue handling, and rice variety selection. The core intervention in this first project is alternate wetting and drying: instead of keeping paddies continuously submerged, farmers allow fields to dry periodically before re-irrigating. With more oxygen reaching the soil, the anaerobic microbes responsible for methane production become less active. The methodology also covers newer approaches such as applying methanotrophic bacteria and planting improved rice varieties bred for lower methane output.
The project proponent, Core CarbonX Solutions, provides farmers with field water tubes to monitor water levels, along with training and technical support. Revenue from credit sales is shared with participating farmers, creating a direct financial incentive for practice change. The validation and verification body for the project was VKU Certification Private Limited.
Who gains and who faces pressure
The clearest winners are smallholder rice farmers in emission-intensive regions who now have a monetizable pathway for adopting AWD. Project developers specializing in agricultural carbon also gain a credible, Verra-backed methodology they can replicate across geographies. The 13 projects already in the pipeline, spanning nine countries, suggest early movers are positioning quickly.
On the other side, buyers relying on forestry or renewable energy credits may face pressure to diversify their portfolios toward agricultural methane reduction, particularly as regulators and rating agencies scrutinize credit quality. Companies in rice supply chains (processors, exporters, food brands) that have not yet engaged with on-farm methane reduction may find themselves behind peers who secured early access to these credits.
What remains unresolved
Several open questions will shape whether VM0051 scales meaningfully. First, permanence monitoring: AWD requires ongoing farmer compliance, and the methodology’s approach to reversals across thousands of smallholder plots has not yet been tested at large scale. Second, pricing: it is unclear where rice methane credits will trade relative to other avoidance credits, and whether the revenue share reaching farmers will be sufficient to sustain behavior change without continued subsidies from project proponents. Third, MRV infrastructure: measuring water levels and methane flux across dispersed paddies is more complex than monitoring a wind farm, and the cost of robust measurement, reporting, and verification could limit expansion in lower-income regions. Finally, the interaction between voluntary credits under VCS and compliance mechanisms (such as Article 6 of the Paris Agreement) remains undefined for rice-sector projects, leaving regulatory risk for early movers.
