Agricultural Carbon Credits in India – A Practical Guide to Soil Carbon, Rice Cultivation, and the Farmer Income Opportunity
Introduction: The New Harvest
Indian farmers are discovering a new harvest—not from their fields, but from the carbon stored in their soil.
The numbers are compelling. The India carbon credit market is estimated to be valued at USD 5.90 billion in 2026 and is expected to reach USD 66.79 billion by 2033. Agriculture is moving from the margins to the centre of India's climate market.
India has opened a new door for agricultural carbon finance. On June 30, 2026, the Bureau of Energy Efficiency published a methodology under the Indian Carbon Market for reducing emissions through improved rice cultivation. The methodology recognises Alternate Wetting and Drying (AWD), aerobic cultivation, and a shift from transplanted to direct-seeded rice.
This is a significant policy advance. Rice methane mitigation has moved from scattered voluntary initiatives to a formal domestic carbon-market pathway.
In January 2026, Indian agriculture reached a major milestone with the approval of the Aadi project (VCS 2590) , a regenerative agriculture soil-carbon project developed by Grow Indigo under Verra. This marked the first issuance of high-integrity soil carbon credits from India—and the first smallholder soil carbon credit issuance globally.
This guide provides a comprehensive overview of agricultural carbon credits in India—soil carbon, rice cultivation, and the farmer income opportunity.
What Are Agricultural Carbon Credits?
Definition
Agricultural carbon credits are generated when farmers adopt regenerative agricultural practices that increase the amount of carbon stored in the soil or reduce greenhouse gas emissions from farming activities.
How Soil Carbon Sequestration Works
- Photosynthesis: Plants absorb CO₂ from the atmosphere
- Root exudates: Plants release carbon compounds into the soil
- Decomposition: Organic matter breaks down and becomes soil organic carbon
- Stabilisation: Carbon becomes protected in soil aggregates
How Rice Cultivation Generates Credits
Rice cultivation generates carbon credits through two primary mechanisms:
| Mechanism | Description |
|---|---|
| Methane Reduction | Reduced methane (CH₄) emissions from flooded paddy fields |
| Nitrous Oxide Reduction | Reduced nitrous oxide (N₂O) emissions from fertiliser application |
Why Agricultural Carbon Credits Matter
| Benefit | Description |
|---|---|
| Climate mitigation | Removes CO₂ from the atmosphere |
| Soil health | Improves fertility, water retention, and microbial activity |
| Crop yields | Increases agricultural productivity |
| Resilience | Enhances drought and flood resistance |
| Farmer income | Creates a new income stream |
The India Opportunity: 47 Million Hectares of Rice, 200 Million Tonnes of Residue
The Numbers
| Metric | Value |
|---|---|
| Rice Production (2025-26) | 154.02 million tonnes |
| Area Under Cultivation | 47 million hectares |
| Crop Residue Generated | 200 million tonnes annually |
| States with High Rice Area | West Bengal, Uttar Pradesh, Punjab, Andhra Pradesh, Odisha |
The Emission Profile
Rice cultivation is a significant source of greenhouse gas emissions. The primary sources are:
| Source | Description |
|---|---|
| Methane (CH₄) | Released from flooded paddy fields where organic matter decomposes anaerobically |
| Nitrous Oxide (N₂O) | Released from nitrogen fertiliser application |
| Residue Burning | Burning of rice straw after harvest releases CO₂ and other pollutants |
The Opportunity
With 47 million hectares under rice cultivation, even a fraction of this area adopting climate-smart practices could generate significant carbon credits.
Soil Carbon Credits: The VM0042 Methodology
What Is VM0042?
VM0042 is a rigorous, science-based methodology for improved agricultural land management and soil carbon outcomes. It is widely regarded as among the most rigorous methodologies for soil carbon, setting a high bar for permanence, additionality, and transparency.
Key Requirements
| Requirement | Description |
|---|---|
| Baseline sampling | Soil samples must be taken to establish baseline carbon levels |
| Monitoring | Regular monitoring of soil carbon levels |
| Verification | Third-party verification by an accredited agency |
| Permanence | Carbon must be stored for at least 10 years (buffer contributions required) |
| Additionality | Must be demonstrated using approved tools |
| Co-benefits | Contribution to sustainable development goals |
The Grow Indigo Aadi Project
The Aadi project (VCS 2590) is a regenerative agriculture soil-carbon project developed by Grow Indigo under Verra.
| Metric | Value |
|---|---|
| Location | Punjab and Haryana |
| Area covered | ~30,000 acres (initial); 140,000 hectares at maturity |
| Credits issued | More than 50,000 credits |
| Farmer share | 75% of carbon credit proceeds flow directly to farmers |
Rice Cultivation Credits: The BM AG04.002 Methodology
What Is BM AG04.002?
BM AG04.002 is a methodology published by the Bureau of Energy Efficiency (BEE) under the Indian Carbon Market in June 2026. It creates a formal pathway for crediting emission reductions from improved rice cultivation.
What the Methodology Covers
| Practice | Description |
|---|---|
| Alternate Wetting and Drying (AWD) | Allowing an irrigated paddy field to dry to a safe threshold before being flooded again |
| Intermittent Flooding | Periodic flooding instead of continuous flooding |
| Aerobic Cultivation | Growing rice in non-flooded conditions |
| Direct-Seeded Rice | Shifting from transplanted to direct-seeded rice |
| Improved Nitrogen Management | More efficient use of nitrogen fertilisers |
| Avoided Residue Burning | Managing rice straw instead of burning it |
| Low-Emission Varieties | Rice varieties with lower methane emissions |
| Biochar Application | Adding biochar to soil |
The Methodology's Limitations
The methodology explains how projects establish baselines, monitor fields and calculate emission reductions. It does not decide who will finance the transition, how farmers will be paid before credits are issued, who will control the carbon asset, or how sale proceeds will be shared.
Agricultural Carbon Credits Under Verra: VM0051
What Is VM0051?
VM0051 Improved Management in Rice Production Systems is a methodology under Verra's Verified Carbon Standard (VCS) program. It provides a framework for quantifying emission reductions from improved rice cultivation practices.
The Revision
On 20 July 2026, Verra published a revised version (v1.1) of VM0051, refining guidance for project area stratification and quantification procedures.
Key Changes
| Change | Description |
|---|---|
| VCS Version 5 Alignment | Program rules and requirements following the launch of version 5 |
| Stratification Guidance | Refined guidance for project area stratification |
| Quantification Procedures | Refined guidance for quantification procedures |
Which Registry to Choose
| Registry | Best For |
|---|---|
| Verra (VM0051) | International buyers, premium pricing |
| BEE (BM AG04.002) | Indian compliance market, lower costs |
The Farmer Economics: Water Savings, Yield, and Carbon Revenue
The Three Benefits
The economic case for improved rice cultivation rests on three linked benefits:
Benefit 1: Water Savings
| Aspect | Description |
|---|---|
| Alternate Wetting and Drying | Can reduce irrigation demand without compromising yield |
| Pumping Costs | Lower pumping costs from reduced water use |
| Water Scarcity | Reduces pressure on water resources |
Benefit 2: Carbon Revenue
| Aspect | Description |
|---|---|
| Tradable Credits | Every tonne of verified greenhouse-gas reduction may generate a tradable credit |
| Income Stream | Additional income from carbon credits |
| Price Potential | Carbon credit prices expected to rise |
Benefit 3: Sustainable Agricultural Land Management
| Aspect | Description |
|---|---|
| Better Nutrient Use | More efficient use of fertilisers |
| Residue Management | Reduced burning and improved soil health |
| Improved Soil and Water Practices | Enhanced resource-use efficiency and resilience |
Revenue Estimates
| Project Type | Credits/Year | Price/Credit (₹) | Annual Revenue |
|---|---|---|---|
| Soil Carbon | 50,000 | ₹800 | ₹4 crore |
| Rice Cultivation | 10,000 | ₹800 | ₹80 lakh |
The Farmer Share
Farmers should receive a defined majority of net carbon revenue, preferably at least 60 per cent. In the Grow Indigo Aadi project, farmers receive 75% of carbon credit proceeds.
The Role of Farmer Producer Organisations (FPOs)
The Institutional Barrier
The biggest barrier to agricultural carbon projects is institutional. Most Indian farms are small and fragmented, while water management is often collective.
The Aggregation Imperative
Carbon projects involve costs for feasibility assessment, baseline studies, training, mapping, monitoring, verification, registration, and credit marketing. An individual smallholder cannot undertake these functions economically. Aggregation is the foundation of a viable carbon market.
The FPO Opportunity
Farmer Producer Organisations (FPOs) can become the backbone of this market. India has formed 10,000 FPOs covering more than 56 lakh farmers.
What FPOs Can Do
| Function | Description |
|---|---|
| Organise Farmers | By village, irrigation source, and cultivation pattern |
| Coordinate Water Scheduling | Manage AWD implementation across plots |
| Arrange Training | Build farmer capacity |
| Maintain Records | Document practices and yields |
| Support Verification | Facilitate third-party verification |
| Negotiate with Developers | Engage with project developers and investors |
| Ensure Transparent Distribution | Distribute carbon revenue fairly |
The FPO as Carbon Service Enterprise
An FPO must not become merely a channel for collecting signatures and land records. It should negotiate project terms, maintain membership and payment registers, review deductions, support grievance redressal and represent farmers during verification. Its compensation should be a disclosed service fee linked to defined functions, not an open-ended commission deducted from farmer revenue.
The Institutional Challenge: Small and Fragmented Holdings
The Challenge
| Challenge | Description |
|---|---|
| Small Holdings | Average farm size in India is small, making individual participation uneconomical |
| Fragmentation | Farmers often have multiple scattered plots |
| Collective Water Management | Water management often depends on canal schedules or shared pumps |
| Coordination Costs | Coordinating across multiple farmers is costly and complex |
The Aggregation Solution
| Solution | Description |
|---|---|
| FPO Aggregation | FPOs aggregate farmers into a single project |
| Village-Level Coordination | Projects operate at the village or irrigation command level |
| Digital Platforms | Technology enables aggregation and monitoring |
The Role of Technology
| Technology | Application |
|---|---|
| Satellite Imagery | Monitor land use and water management |
| Digital Records | Track practices and yields |
| Mobile Apps | Enable farmer reporting |
| Blockchain | Ensure transparency and traceability |
The Role of Technology: Satellite Monitoring and Verification
Why Technology Matters
MRV (Monitoring, Reporting, and Verification) is critical for carbon credit integrity. Agricultural carbon projects require robust MRV systems to ensure that emission reductions are real and verifiable.
Satellite Monitoring
Satellite imagery can be used to:
| Application | Description |
|---|---|
| Land Use Monitoring | Track rice cultivation areas |
| Water Management | Monitor flooding and drying patterns |
| Practice Adoption | Detect changes in cultivation practices |
| Verification | Provide independent verification of project activities |
IoT Sensors
Indian startups like RenewCred are using IoT sensors, AI verification, and blockchain to turn agricultural waste into tradeable carbon credits.
Digital MRV
RenewCred has built a layered Digital Monitoring, Reporting and Verification (DMRV) system that integrates IoT sensors, AI verification, and blockchain.
The Farmer Payment Structure: Three-Part Model
The Conventional Model
Under the conventional model, farmers change practices, the project is monitored and verified, credits are issued, and payment follows after sale. This may take several seasons. The farmer carries the immediate risk while revenue remains uncertain.
The Three-Part Payment Structure
Rice-carbon projects should instead adopt a three-part payment structure:
| Payment Type | Description |
|---|---|
| Adoption Payment | Cover training, water-management tools, data collection and additional field effort |
| Performance Payment | Follow each season once the agreed practice is independently verified |
| Carbon Dividend | Paid after credits are sold |
The Financing Model
Only the dividend should depend on the carbon price. Adoption and performance payments should be treated as implementation costs and financed by investors, concessional climate capital or convergence with agricultural and irrigation programmes.
Transparent Revenue Sharing
Farmers should receive a defined majority of net carbon revenue, preferably at least 60 per cent. Projects must disclose the credit sale price, total revenue, deductions and farmer-wise payment.
Success Story: Grow Indigo's Aadi Project
The Project
The Aadi project (VCS 2590) is a regenerative agriculture soil-carbon project developed by Grow Indigo under Verra. In January 2026, it became the first project in India to be issued credits under VM0042—and the first smallholder soil carbon credit issuance globally.
Key Milestones
| Date | Milestone |
|---|---|
| January 2026 | Project approved under Verra VM0042 |
| February 2026 | First issuance of 57,463 carbon credits |
The Methodology Choice
"We chose VM0042 because it is a rigorous, science-based methodology for improved agricultural land management. It credibly quantifies both soil carbon gains and greenhouse gas emission reductions using a strong measuring, reporting, and verification framework."
The Farmer Share
75% of carbon credit proceeds flow directly back to farmers. The project estimates an ~7% increase in farmer incomes.
The Significance
This project demonstrates that high-integrity, science-led soil carbon credits can be delivered at scale in India, creating a new income stream for smallholder farmers while restoring soil health and resilience.
Success Story: The Amazon Rice Credit Deal
The Deal
In April 2026, The Good Rice Alliance announced a landmark offtake agreement with Amazon covering more than 685,000 metric tons of CO₂e in carbon credits during the initial crediting phase. The deal is valued at approximately USD 30 million.
The Practices
The agreement supports TGRA's large-scale program working with smallholder rice farmers to reduce methane emissions through the adoption of improved water-management practices, including Alternate Wetting and Drying (AWD) and Direct Seeded Rice (DSR).
The Significance
This deal demonstrates the growing demand for high-integrity agricultural carbon credits from Indian farmers. It also shows that corporate offtake agreements can provide price certainty and volume certainty for agricultural carbon projects.
Success Story: RenewCred's Digital Infrastructure
The Company
RenewCred, a Bengaluru startup founded by Abhimanyu Rathi and Yogendra Panchal, uses IoT sensors, AI verification, and blockchain to turn agricultural waste into tradeable carbon credits.
The Impact
| Metric | Value |
|---|---|
| Emissions reduced, avoided, or removed | 100,000 tonnes of CO₂e |
| Projects | 22 projects across Gujarat, Madhya Pradesh, Maharashtra, Tamil Nadu and Telangana |
| Scientists | 93 from 6 countries |
The Infrastructure-First Approach
Rather than rushing to market, RenewCred spent nearly two years in pre-launch development. The founders assembled a scientific advisory network of 93 researchers across six countries, working to develop methodologies, verification frameworks, and digital monitoring systems.
The Significance
RenewCred demonstrates that technology can solve the credibility problem in agricultural carbon markets. By building digital MRV infrastructure, the company is creating credits that can withstand scrutiny.
