In a landmark move that underscores the evolving relationship between global corporate climate strategy and nature-based solutions, biopharmaceutical giant GSK has entered into a significant eight-year agreement with the carbon removal developer Varaha. The deal, which aims to procure over 500,000 carbon credits, represents more than just a carbon accounting exercise; it is a holistic investment in the socio-economic and environmental transformation of the agricultural landscape in northern India.
The initiative, structured with the assistance of the nature-focused investment platform Earthly, focuses on expanding regenerative agricultural practices across 50,000 hectares of farmland in the states of Punjab and Haryana. By incentivizing smallholder farmers to abandon carbon-intensive, traditional methods in favor of sustainable alternatives, the partnership provides a blueprint for how large-scale corporations can address their residual emissions while simultaneously fostering public health and community resilience.
The Core Agreement: A Strategic Pillar for Net Zero
At the heart of this agreement is a clear, long-term commitment to high-quality carbon removal. GSK, which has set an ambitious Science Based Targets initiative (SBTi)-approved goal to reach net-zero greenhouse gas emissions across its entire value chain by 2045, faces the challenge of neutralizing its inevitable residual emissions.
Under the terms of the deal, the project is expected to generate approximately 100,000 tonnes of carbon removal credits annually between 2028 and 2033. This volume is significant, accounting for roughly 7% of GSK’s forecast residual emissions based on its current carbon reduction pathway. By locking in this supply through 2033, GSK is securing a reliable, verified, and high-impact stream of offsets that align with its internal climate mandate to achieve a 90% absolute reduction in emissions from a 2020 baseline across all scopes.
Chronology: The Evolution of the Partnership
The trajectory of this collaboration reflects the rapid maturation of the carbon credit market.
- 2022: Varaha is founded in India with the explicit mission to sequester one billion tonnes of CO2e on smallholder lands, recognizing that the frontline of the climate crisis often resides on the small, family-owned farms that define India’s agricultural sector.
- Early Development Phase: Varaha begins identifying regions where conventional practices—specifically intensive tillage, flood-irrigated rice farming, and the widespread practice of burning crop residue—are contributing heavily to regional air pollution and soil degradation.
- Initial Monitoring Period: Early trials cover 42,000 hectares, providing proof-of-concept data. The results show a 12% to 16% increase in household income for participating farmers, alongside a massive reduction in fine particulate matter (PM2.5) and significant water conservation.
- 2024/2025 (Strategic Alignment): GSK, seeking to move beyond generic offsets, identifies the Varaha project as a match for its own "environmental sustainability as a core to human health" philosophy.
- The Agreement (2025/2026): The eight-year partnership is officially signed, with Earthly facilitating the complex structuring required to ensure transparency and compliance with international carbon standards.
Supporting Data: Measuring the Impact
The efficacy of the Varaha model lies in its empirical approach to regenerative change. By moving farmers away from traditional, resource-heavy methods, the project delivers measurable benefits that extend far beyond simple carbon sequestration.

Environmental Metrics
- Air Quality: During the project’s initial monitoring phase, the shift away from burning crop residue prevented the release of 4,574 tonnes of fine particulate matter (PM2.5). Given that northern India suffers from some of the world’s most severe air quality crises, this is a critical health co-benefit.
- Water Conservation: Through the transition to Direct Seeded Rice (DSR) and other water-efficient practices, the project successfully saved approximately 59.5 billion liters of water. In regions where groundwater depletion is a systemic risk, this efficiency is vital for long-term farm viability.
- Soil Health: The move toward reduced tillage and the incorporation of crop residue into the soil instead of burning it has led to a significant increase in soil organic carbon, effectively turning the soil into a long-term carbon sink.
Economic Metrics
The "burning stops when the alternative pays" philosophy is supported by concrete economic data. Participating households recorded an average income increase of 12% to 16%. This financial gain is driven by three primary factors:
- Cost Reduction: Lower expenditures on fertilizers and other inputs.
- Yield Optimization: Improved soil health leading to higher crop output.
- Revenue Sharing: A direct payout to farmers from the sale of carbon credits, which helps offset the capital expenditure required to purchase or lease the machinery needed for regenerative farming.
Official Perspectives: The Philosophy Behind the Project
GSK’s Perspective: Health and Resilience
Adele Cheli, VP of Environmental Sustainability at GSK, frames the project not merely as a climate obligation, but as a component of the company’s core business mission. "For GSK, environmental sustainability is core to business resilience and human health," Cheli noted. By focusing on projects that improve air quality and water availability, the company is effectively linking its climate targets to the health outcomes of the populations in the regions where its suppliers operate. This is a strategic shift from "purchasing" credits to "investing" in sustainable ecosystems.
Varaha’s Perspective: Solving the Burning Crisis
Madhur Jain, Co-founder and CEO of Varaha, emphasizes the pragmatism required to effect change at scale. Addressing the systemic issue of crop residue burning, Jain explains: "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."
Jain’s insight is crucial for corporate stakeholders: regenerative agriculture cannot be enforced through regulation alone; it must be economically viable. "We work with more than 200,000 farming families and the lesson is consistent: burning stops when the alternative pays. Credit revenue pays for the equipment and the extra labour."
The Broader Implications for Global Industry
The GSK-Varaha partnership carries profound implications for how the pharmaceutical industry—and indeed, all high-emitting sectors—will approach the "residual emissions" portion of their net-zero pathways in the coming decade.
The Rise of High-Quality Nature-Based Solutions
For years, the voluntary carbon market was criticized for a lack of transparency and low-quality offsets. The structure of this agreement—involving a professional developer (Varaha), a neutral intermediary (Earthly), and a corporate buyer (GSK)—signals a shift toward high-integrity, nature-based removals. These projects are harder to verify than simple renewable energy credits, but they provide the "co-benefits" (biodiversity, health, water security) that modern ESG reporting frameworks increasingly demand.

Scaling the Smallholder Model
The challenge remains one of scale. While 50,000 hectares is a significant footprint, it is a fraction of the millions of hectares across India that are still subject to burning. The success of this eight-year partnership could provide the "proof-of-scale" necessary to attract further institutional capital. If farmers can consistently increase their income by 15% while simultaneously helping global firms meet their net-zero targets, the model could be replicated across other agrarian economies in Southeast Asia, Africa, and Latin America.
Integration of Health and Climate
GSK’s involvement highlights a growing trend: the convergence of public health and climate action. Air pollution, specifically PM2.5, is a major contributor to respiratory and cardiovascular disease. By investing in a project that directly reduces the burning of biomass, GSK is essentially mitigating the health risks associated with regional environmental degradation. This creates a powerful narrative for stakeholders, demonstrating that the company’s net-zero journey is intrinsically linked to the wellbeing of the communities it serves.
Conclusion
The partnership between GSK and Varaha is more than a commercial transaction for carbon credits; it is a sophisticated, long-term intervention into the agricultural systems of northern India. By aligning the economic incentives of smallholder farmers with the carbon sequestration goals of a global healthcare leader, the project demonstrates that the path to net-zero can be paved with tangible improvements to soil, water, air, and household prosperity.
As the world looks toward 2045 and beyond, the success of this agreement will likely serve as a foundational case study for how global corporations can move beyond the "offsetting" mentality and toward a model of "regenerative investment." The challenge will be to scale this impact from 50,000 hectares to the millions required to make a truly global difference—a task that rests on the continued collaboration of technology developers, financial platforms, and corporate leaders committed to the long game.
