GSK Signs 8-Year Carbon Deal With India's Varaha

GSK has entered an eight-year emissions reduction purchase agreement supporting regenerative agriculture across 50,000 hectares of smallholder farmland in Punjab and Haryana, India, facilitated by Earthly between GSK and carbon removal developer Varaha. The project aims to reduce crop residue burning while increasing soil carbon storage, expected to generate around 100,000 tonnes of removal credits annually between 2028 and 2033, equivalent to approximately 7 percent of GSK's forecast residual emissions under its current carbon reduction pathway.

 

Why Crop Residue Burning's Economic Logic Explains Why Interventions Must Address Cost Directly

 

Varaha co-founder and CEO Madhur Jain specifically explained the underlying economic driver behind India's crop burning problem: "India burns roughly 100 million tonnes of crop residue a year. It burns because for a smallholder with a few days between harvest and sowing, fire is free and every alternative costs money." That framing identifies precisely why crop burning has proven such a persistent practice despite widely documented air quality and health consequences, farmers operating on tight margins between harvest and the next planting cycle face a stark economic calculation, where burning residue is essentially costless and immediate, while alternative disposal or incorporation methods require additional equipment, labour or time that directly costs money the farmer may not readily have available.

That economic reality explains why this project's structure specifically combines subsidised machinery access with a direct share of carbon credit revenue, rather than relying on regulatory bans or awareness campaigns alone, approaches that have historically struggled to shift behaviour precisely because they don't address the core cost barrier Jain identifies. As Jain put it directly, "burning stops when the alternative pays," positioning the carbon credit revenue not as a supplementary benefit but as the specific financial mechanism making the alternative practice genuinely viable for farmers operating on tight economic margins.

Why the PM2.5 Co-Benefit Figure Connects This Project to a Severe Regional Air Quality Crisis

 

The release states that during its first monitoring period covering 42,000 hectares, the project avoided the release of 4,574 tonnes of PM2.5 fine particulate matter from burning. That figure connects this carbon project directly to one of South Asia's most severe recurring public health crises: crop residue burning in Punjab and Haryana is widely documented as a major contributor to the severe seasonal air pollution affecting northern India, including New Delhi, during the post-harvest burning season each year, when particulate matter levels frequently reach hazardous concentrations affecting tens of millions of people across the region.

That air quality co-benefit gives this carbon project a genuinely distinct value proposition beyond its climate function alone, since reducing crop burning directly addresses a documented, severe public health emergency affecting a considerably larger population than the smallholder farmers directly participating in the programme, extending the project's benefit to the broader regional population exposed to this seasonal pollution crisis.

 

Why the VM0042 Version Upgrade Signals a Meaningful Credibility Distinction

 

The release specifies that as part of the GSK agreement, the project "is upgrading to VM0042 version 2.2, which has been approved under the Integrity Council for the Voluntary Carbon Market's (ICVCM) Core Carbon Principles." That specific version upgrade detail matters considerably given the broader carbon market credibility scrutiny examined extensively throughout this batch, including South Pole's KPMG assurance milestone and Deep Sky's Sylvera pre-issuance rating, both reflecting a market increasingly differentiating credit quality based on independently verified methodology standards.

ICVCM Core Carbon Principles approval represents a specific, recognised benchmark within the voluntary carbon market that certain methodologies meet a defined threshold of environmental integrity, meaning this project's specific upgrade to a CCP-approved methodology version, rather than continuing to operate under an earlier, potentially less rigorously assessed version of the same underlying VM0042 methodology, suggests GSK specifically required or prioritised this credibility upgrade as a condition of its purchase agreement, reflecting the kind of quality differentiation increasingly demanded by corporate buyers making large, long-term carbon credit commitments.

Why the Farmer Income Data Reveals a Distinct Economic Value Proposition Beyond Carbon Revenue Alone

 

The release states participating farming households have recorded average income increases of between 12 and 16 percent since joining the programme, attributed to "higher yields, lower fertiliser expenditure and carbon revenues" collectively, rather than carbon revenue alone. That breakdown matters for understanding the programme's genuine economic sustainability for participating farmers: if the income improvement depended entirely on carbon credit revenue, that income stream would carry ongoing dependency risk tied to continued carbon market demand and pricing, a market that can fluctuate over time.

Instead, the disclosed combination of higher yields, reduced fertiliser costs and carbon revenue together suggests farmers are experiencing genuine operational and agronomic improvements from the regenerative practices themselves, independent of the carbon credit revenue specifically, a distinction that matters for assessing whether farmers would have meaningful incentive to continue these improved practices even if carbon credit demand or pricing were to change in the future, since the underlying agronomic benefits, higher yields and reduced input costs, would presumably persist regardless of carbon market conditions specifically.
