Agricultural Carbon Credits – VM0042 Methodology and Farmer Revenue Potential in India

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. Over 2 lakh farmers are now using AI, satellite imagery, and regenerative farming to earn from carbon credits while restoring the land. These farmers have brought 1.1 million acres under climate-positive agriculture, removing 2 million tonnes of carbon.

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.

The project used VM0042, a rigorous, science-based methodology for improved agricultural land management and soil carbon outcomes. As the Grow Indigo team explained: "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".

Agricultural carbon credits represent a significant opportunity for Indian farmers and project developers. With the India carbon credit market projected to grow at 41.4% CAGR from 2026 to 2033, the potential is enormous.

This guide provides a comprehensive overview of agricultural carbon credits in India, the VM0042 methodology, farmer revenue potential, and how to participate in this growing market.

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. This carbon sequestration is quantified, verified, and sold as carbon credits.

How Soil Carbon Sequestration Works

1. Photosynthesis: Plants absorb CO₂ from the atmosphere
2. Root exudates: Plants release carbon compounds into the soil
3. Decomposition: Organic matter breaks down and becomes soil organic carbon
4. Stabilisation: Carbon becomes protected in soil aggregates

Why Soil Carbon Matters

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
Biodiversity	Supports soil ecosystems

The India Context

India has over 147 million hectares of agricultural land. Even a fraction of this land adopting regenerative practices could generate significant carbon credits and farmer income.

The Grow Indigo Aadi Project: India's First Smallholder Soil Carbon Credits

The Project

The Aadi project (VCS 2590) is a regenerative agriculture soil-carbon project developed by Grow Indigo under Verra.

Key Milestones

Date	Milestone
January 2026	Project approved under Verra VM0042
February 2026	First issuance of 57,463 carbon credits

Why This Project Matters

Significance	Description
First in India	First project in India to be issued credits under VM0042

Farmer Revenue Potential: What Farmers Can Earn

The Revenue Model

Farmers don't participate individually. Instead, they participate through project developers who:

• Aggregate farmers into a single project
• Provide technical support and training
• Handle measurement, reporting, and verification
• Sell credits and share revenue with farmers

The Farmer Share

Farmers typically receive 60-80% of the carbon credit revenue, with the project developer taking the remainder for costs and services.

Annual Income Estimates

Farm Size	Practice	Annual Carbon Sequestration	Revenue at ₹800/credit
1 acre	Regenerative agriculture	0.5 – 1.0 tonnes	₹400 – ₹800
5 acres	Regenerative agriculture	2.5 – 5.0 tonnes	₹2,000 – ₹4,000
10 acres	Regenerative agriculture	5.0 – 10.0 tonnes	₹4,000 – ₹8,000

Note: Actual sequestration varies by soil type, climate, and practices.

The Grow Indigo Model

75% of carbon credit proceeds flow directly back to farmers, providing a significant income boost. The project estimates an ~7% increase in farmer incomes.

The Long-Term Value

Soil carbon credits are not a one-time payment. They can provide annual income for 10-20 years as carbon continues to be sequestered in the soil.

The Co-Benefits

Beyond carbon revenue, farmers benefit from:

• Improved soil health: Increased organic carbon enhances moisture retention and supports microbial activity
• Reduced chemical inputs: Lower dependence on chemical fertilisers
• Increased yields: Healthier soil produces better crops
• Resilience: Better drought and flood resistance

Regenerative Agricultural Practices That Generate Credits

Key Practices

Practice	Description	Carbon Impact
No-till farming	Avoiding ploughing to prevent soil disturbance	High
Cover cropping	Growing cover crops to protect and enrich soil	High
Crop rotation	Diverse crop rotations to improve soil health	Medium
Composting	Adding organic matter to soil	Medium
Agroforestry	Integrating trees with crops	High
Biochar application	Adding biochar to soil	High
Reduced chemical fertiliser	Decreasing synthetic fertiliser use	Medium

The VM0042 Requirement

Under VM0042, certification will not be granted if a reduction of chemical fertiliser use results in a decrease in yields. This ensures that farmers are not penalised for adopting sustainable practices.

The Yield Protection

This requirement protects farmers and ensures that carbon projects do not compromise food production.

---

The Additionality Requirement in Agricultural Carbon Projects

What Is Additionality?

Additionality is the requirement that the project would not have happened without the revenue from carbon credits. It is the single most important factor in determining whether an agricultural carbon project qualifies for credits.

Why Additionality Matters

If the regenerative practices would have been implemented anyway (due to cost savings or other benefits), the project does not represent genuine additional climate action.

How to Demonstrate Additionality

Test	Description
Financial barriers	The project needed carbon revenue to be viable
Technological barriers	The project required investment in unproven technology
Institutional barriers	The project faced regulatory or policy hurdles
Common practice analysis	The practices are not common in the region

The VM0042 Additionality Tests

VM0042 requires project proponents to demonstrate additionality using approved tools and methods. This is a rigorous process that requires careful documentation.

---

The Permanence Challenge and Buffer Pools

What Is Permanence?

Permanence is about how long the carbon benefit lasts. For agricultural carbon projects, there is a risk that the carbon could be released back into the atmosphere if practices are abandoned.

Why Permanence Matters

VM0042 sets a high bar for permanence. Projects must demonstrate that carbon will remain stored for at least 10 years.

The Buffer Pool

Quality projects have buffer pool contributions — a reserve of credits that cannot be traded. If carbon is released (e.g., due to drought or practice abandonment), buffer credits are used to compensate.

How Buffer Pools Work

Step	Description
1. Risk Assessment	Assess the risk of reversal
2. Buffer Contribution	Deposit a percentage of credits into the buffer pool
3. Non-Transferable	Buffer credits cannot be traded
4. Compensation	If a reversal occurs, buffer credits are used

The VM0042 Permanence Requirements

VM0042 is widely regarded as setting a high bar for permanence. Projects must have robust permanence mechanisms in place.
