Agricultural Carbon Credits in India: Soil Payouts and CCTS Framework

Overview

Agricultural carbon credits have emerged as a market-driven instrument in India to monetise sustainable farming practices, transforming soil organic carbon sequestration into tradable financial assets for smallholders transitioning away from ecologically damaging monocultures. In September 2026, the direct disbursement of ₹2.5 to ₹2.9 crore to 2,550 farmers in Punjab and Haryana demonstrated that voluntary carbon finance can incentivise groundwater conservation and the elimination of crop stubble burning. While this milestone validates private-sector aggregation and digital verification models, scaling agricultural carbon markets across India requires robust statutory floor pricing, low-cost remote measurement, and cooperative-led aggregation to prevent corporate intermediary capture.

In September 2026, the Indian agricultural sector achieved a significant milestone when 2,550 smallholder farmers across Punjab and Haryana received India's first farm-level soil carbon payments via Direct Benefit Transfer. The disbursement event, hosted at Punjab Agricultural University in Ludhiana, distributed approximately ₹2.5 to ₹2.9 crore in direct cash payouts to participating growers.

These payments represent verified carbon offsets generated between 2019 and 2022 under an initiative known as the 'Aadi' project (registered as VCS Project 2590). Developed by agricultural carbon developer Grow Indigo in scientific collaboration with the Indian Council of Agricultural Research (ICAR), the project translates farm-level climate mitigation into measurable, monetisable assets. As of September 2026, this rollout marks the first large-scale empirical test of voluntary soil carbon markets in India's agrarian heartland.

Soil carbon credits represent certified units of greenhouse gas mitigation, where one credit equals one metric tonne of carbon dioxide equivalent sequestered in soil or avoided in emissions. Agricultural soils act as natural carbon sinks through the biological accumulation of Soil Organic Carbon (SOC), which increases when farmers minimise mechanical soil disturbance and retain plant biomass.

Under international voluntary carbon standards, such as Verra's VM0042 methodology for Improved Agricultural Land Management, generating tradeable credits follows a rigorous, multi-stage compliance cycle:

1. Baseline Setting and Stratification: Project developers establish historical greenhouse gas emission baselines across target farmlands using regional agronomic data and historical cropping patterns.
2. Adoption of Regenerative Interventions: Farmers implement approved conservation practices, including zero-tillage, residue mulching, and non-continuous flooded irrigation.
3. Measurement, Reporting, and Verification (MRV): Soil sampling protocols mandate physical soil core extraction to a minimum depth of 30 cm to quantify ex-post changes in mineral soil organic carbon stocks per Intergovernmental Panel on Climate Change (IPCC) standards.
4. Third-Party Validation and Issuance: Independent designated operational entities audit the agronomic logs, model estimates, and laboratory tests before registries issue tradable Voluntary Carbon Units (VCUs).

The 'Aadi' project in Punjab and Haryana provides an operational blueprint for deploying voluntary carbon finance within intensive, input-heavy agricultural ecosystems. Covering approximately 30,000 acres of smallholder farmland, the project generated over 50,000 verified carbon credits during its 2019–2022 monitoring cycle.

Participating farmers adopted integrated conservation practices that addressed the structural ecological crises plaguing northwest India. The primary agronomic interventions focused on replacing conventional puddled transplanting with Direct Seeded Rice (DSR), adopting low-tillage seeders for wheat sowing, and eliminating paddy stubble burning.

The environmental dividends of this transition extended beyond carbon sequestration. The Indian Council of Agricultural Research documented that participating farms conserved 45 billion litres of groundwater and prevented over 200,000 tonnes of crop residue from open-field burning, preventing approximately 1,000 tonnes of particulate matter (PM2.5) air pollution.

Grow Indigo structured the commercial transactions by contracting a 75% net carbon revenue share directly to participating farmers, providing upfront fixed payments to insulate smallholders against volatile voluntary market settlement cycles.

Agronomic practices eligible for carbon credits alter the biological and chemical dynamics of the soil-rhizosphere interface to prevent methane and nitrous oxide emissions. Conventional paddy cultivation relies on prolonged submergence, which creates anaerobic soil conditions where methanogenic bacteria generate severe methane emissions.

The core regenerative techniques driving agricultural carbon generation include:

• Direct Seeded Rice (DSR): Rice seeds are sown directly into non-puddled fields using specialized seed drills, bypassing wet nursery preparation and field puddling. This eliminates anaerobic decomposition, reducing field methane generation while conserving soil structure.
• Alternate Wetting and Drying (AWD): Intermittent field flooding allows the soil to aerate periodically between irrigation cycles. This aerobic phase disrupts methanogenic pathways, cutting irrigation water demand without suppressing grain yields.
• In-Situ Residue Management: Retaining crop stubble as surface mulch via machines like the Happy Seeder incorporates organic plant biomass into the topsoil, raising soil organic carbon stocks while suppressing weed growth.

The transition from input-intensive cultivation to carbon farming requires structural changes across field operations, resource consumption, and financial remuneration mechanisms.

Measurement, Reporting, and Verification (MRV) expenditures constitute the largest technical barrier to smallholder carbon market participation. Traditional physical soil coring to a depth of 30 cm requires intensive field sampling, cold-chain transport, and laboratory chemical analysis, creating prohibitively high transaction overheads for plots under two hectares.

To overcome this constraint, research by ICAR-IARI confirms that digital MRV (dMRV) systems—which integrate Sentinel-2 multispectral satellite imagery with process-based biogeochemical models such as DNDC—can lower verification costs by up to 90% compared to dense soil coring.

Beyond technological hurdles, agricultural carbon projects face critical regulatory and integrity challenges:

• Additionality Verification: International registries such as Verra require developers to demonstrate that carbon-sequestering practices exceed statutory baselines and have a regional adoption rate below 20%.
• Permanence and Reversal Risks: Sequestered soil carbon faces reversal risks if smallholders return to conventional tillage, burning, or prolonged flooding during subsequent seasons due to tenancy changes or market shocks.
• Governance and Corporate Capture: While Grow Indigo’s 75% payout mirrors global smallholder benchmarks of 60% to 80% (such as Indigo Ag in the US at 75% and Rabobank/Acorn at up to 80%), unequal bargaining power remains an issue. Without statutory floor price protections, private aggregators retain unilateral price-setting power over voluntary credit sales, leaving smallholders vulnerable to contractual opacity.

The Parliament of India established the statutory foundation for domestic carbon markets by amending the Energy Conservation Act, 2001. Specifically, Section 14(w)—introduced via the Energy Conservation (Amendment) Act, 2022—empowers the Central Government to specify a Carbon Credit Trading Scheme (CCTS) and authorize the issuance of Carbon Credit Certificates.

In June 2023, the Ministry of Power formally notified the Carbon Credit Trading Scheme (CCTS), managed by the Bureau of Energy Efficiency (BEE) as the administrative agency. To broaden market participation beyond obligated industrial entities, the Ministry introduced an Offset Mechanism in December 2023. This framework permits non-obligated sectors, including agriculture, forestry, and waste management, to register decarbonisation projects and generate registered offset credits.

Parallel to the CCTS, the Ministry of Environment, Forest and Climate Change (MoEFCC) notified the Green Credit Programme (GCP) under the Environment (Protection) Act, 1986. While the GCP incentivises voluntary, non-carbon environmental actions (such as water harvesting and afforestation) using activity-based green credits, the CCTS operates as India's primary domestic carbon market accounting for greenhouse gas mitigation.

Farmer Producer Organisations (FPOs) and Primary Agricultural Credit Societies (PACS) serve as the primary institutional vehicles to aggregate fragmented landholdings, negotiate fair contracts, and eliminate intermediary rent-seeking in carbon finance.

A forward-looking policy roadmap requires targeted interventions across technical and governance domains:

• Statutory Floor Pricing: Policymakers should establish a regulatory minimum revenue floor for farm-level carbon sales within the domestic CCTS offset market, ensuring smallholders receive transparent compensation tied to prevailing global indices.
• Open-Access Digital MRV Infrastructure: The Indian Council of Agricultural Research and the Ministry of Agriculture should deploy standardized, calibrated digital MRV tools, providing open-source biogeochemical baselines to lower validation expenses for FPOs.
• Contractual Transparency Standards: The Ministry of Agriculture and Farmers Welfare must institute model carbon-farming contract guidelines to prevent predatory lock-in clauses, clarify data ownership, and establish clear dispute-resolution mechanisms.
• Stacking Environmental Rewards: State agricultural departments should align state subsidies (such as DSR promotional assistance) with carbon finance, allowing smallholders to stack ecosystem payments for water conservation, stubble avoidance, and soil health improvement.

• Historic Milestone: In September 2026, 2,550 farmers across Punjab and Haryana received India's first soil carbon payments of ₹2.5 to ₹2.9 crore via Direct Benefit Transfer.
• Agronomic Driver: The payouts stem from 50,000 verified credits under Verra VM0042, achieved through Direct Seeded Rice, no-till wheat, and the complete elimination of stubble burning across 30,000 acres.
• Resource Conservation: The project saved 45 billion litres of groundwater and prevented the burning of 200,000 tonnes of crop residue, abating roughly 1,000 tonnes of PM2.5 air pollution.
• Enabling Legislation: Section 14(w) of the Energy Conservation Act, 2001 (inserted via the 2022 Amendment) provides the statutory basis for India's Carbon Credit Trading Scheme (CCTS) and its voluntary offset mechanism.
• Technology Dividend: Digital MRV frameworks using Sentinel-2 multispectral satellite data and biogeochemical models reduce verification costs by up to 90% relative to physical soil coring.
• Policy Imperative: leaves smallholders exposed to aggregator price-setting power, underscoring the need for institutional aggregation via FPOs and PACS.
