Global biopharmaceutical leader GSK has formalized a long-term strategic partnership with Varaha, a prominent developer of carbon removal projects, to acquire more than 500,000 high-quality carbon credits over the next eight years. This landmark agreement, facilitated by the nature-focused investment platform Earthly, marks a significant step in GSK’s journey toward its 2045 net-zero goal. The credits will be generated through a large-scale regenerative agriculture initiative located in the northern Indian states of Punjab and Haryana, regions traditionally known as the "breadbasket" of India but currently facing severe environmental challenges due to intensive farming practices.
The collaboration focuses on transitioning smallholder farmers away from traditional, resource-heavy agricultural methods toward sustainable, regenerative practices. By supporting the expansion of Varaha’s existing project across approximately 50,000 hectares of farmland, the initiative seeks to sequester carbon within the soil while simultaneously addressing critical public health issues, such as air pollution and water scarcity. This multi-dimensional approach aligns with GSK’s broader corporate strategy, which views environmental health as inextricably linked to human health.
The Strategic Framework of the GSK-Varaha Agreement
The eight-year agreement is structured to provide a consistent stream of carbon removal credits, with a projected delivery of approximately 100,000 tonnes of carbon dioxide equivalent (CO2e) annually between 2028 and 2033. These credits represent roughly 7% of GSK’s anticipated residual emissions, based on the company’s current decarbonization trajectory. By securing these credits now, GSK is effectively de-risking its long-term climate strategy, ensuring it has access to high-integrity nature-based removals to neutralize the final 10% of emissions that cannot be eliminated through direct operational changes.
Earthly, the platform that brokered the deal, specializes in connecting corporations with high-quality nature-based solutions. Their involvement underscores a growing trend in the voluntary carbon market (VCM) toward "boutique" projects that offer clear, verifiable co-benefits beyond simple carbon sequestration. For GSK, the appeal of the Varaha project lies in its ability to deliver measurable improvements in local air quality and water conservation, which directly impact the health of the communities where the project operates.
Addressing the Crisis of Crop Residue Burning in Northern India
One of the most significant environmental hurdles in Northern India is the practice of crop residue burning. Every year, following the rice harvest, farmers in Punjab and Haryana burn millions of tonnes of straw to quickly clear their fields for the subsequent wheat planting. This practice is a primary contributor to the "Great Smog" that blankets New Delhi and the surrounding Indo-Gangetic Plain every winter, leading to a spike in respiratory illnesses, cardiovascular problems, and premature deaths.
Varaha’s project intervenes in this cycle by providing farmers with the financial incentives and technical tools necessary to adopt alternatives. Instead of burning, farmers are encouraged to incorporate crop residues back into the soil, which enhances soil organic carbon and improves fertility. According to Madhur Jain, Co-founder and CEO of Varaha, the economic reality for smallholders is the primary barrier to change. "India burns roughly 100 million tonnes of crop residue a year," Jain noted. "It burns because for a smallholder with a few days between harvest and sowing, fire is free and every alternative costs money."
By utilizing the revenue from carbon credits, the project subsidizes the labor and machinery costs associated with residue management. During the project’s initial monitoring period, which covered 42,000 hectares, the initiative successfully avoided the release of 4,574 tonnes of fine particulate matter (PM2.5). This reduction in air pollution represents a major public health victory, directly supporting GSK’s mission as a healthcare company.
Technological Shifts: From Flooded Paddies to Direct Seeded Rice
Beyond residue management, the project promotes the adoption of Direct Seeded Rice (DSR) and reduced tillage. Traditional rice cultivation in India involves "puddling" or transplanting seedlings into flooded fields. While effective for weed control, this method is incredibly water-intensive and creates anaerobic conditions in the soil that lead to significant methane emissions—a greenhouse gas far more potent than carbon dioxide.
DSR, by contrast, involves sowing seeds directly into the soil, bypassing the nursery and transplanting stages. This technique can reduce water consumption by up to 20-30% and significantly lower methane output. The impact of these changes is already evident in Varaha’s data; the project has reported savings of approximately 59.5 billion liters of water during its first monitoring phase. In a region where groundwater tables are depleting at an alarming rate, such water-saving measures are critical for the long-term viability of Indian agriculture.
Socio-Economic Impact and Farmer Prosperity
A central pillar of the Varaha model is the equitable distribution of benefits to smallholder farmers. Smallholders, defined as those farming on less than two hectares of land, produce the majority of the world’s food but are often the most vulnerable to climate change and economic fluctuations.
Under the agreement with GSK, participating farming families receive a direct share of the revenue generated from the sale of carbon credits. This "carbon dividend" provides a new, diversified income stream that helps buffer against crop failures or market volatility. Early results from the project indicate that participating households experienced a 12% to 16% increase in average income. This boost is attributed to a combination of carbon revenue, reduced expenditures on chemical fertilizers (as soil health improves), and increased crop yields resulting from better soil structure.
By making regenerative agriculture more profitable than conventional farming, Varaha and GSK are creating a self-sustaining ecosystem of sustainable land management. This economic alignment is essential for ensuring that environmental gains are not temporary but represent a permanent shift in how land is managed.
GSK’s Climate Roadmap and the Role of Offsetting
GSK’s commitment to this project is part of a broader, science-based approach to sustainability. The company has set an ambitious target to achieve net-zero greenhouse gas emissions across its entire value chain by 2045. This target has been validated by the Science Based Targets initiative (SBTi), the gold standard for corporate climate goals.
The GSK roadmap follows a strict hierarchy of action:
- Reduction: Achieving a 90% absolute reduction in emissions from a 2020 baseline across Scopes 1, 2, and 3.
- Neutralization: Using high-quality carbon removals to address the remaining 10% of residual emissions.
Adele Cheli, VP of Environmental Sustainability at GSK, emphasized that the company’s sustainability efforts are not just about compliance but are core to its business resilience. "This investment demonstrates how we’re progressing in our net-zero journey, whilst also delivering co-benefits for human health, nature and local communities," Cheli stated. By investing in Varaha’s project now, GSK is securing its future "neutralization" needs while contributing to immediate health and environmental improvements in a key global market.
The Role of Varaha in the Nature-Based Solutions Market
Founded in 2022, Varaha has rapidly emerged as a leader in the Indian carbon removal space. The company’s mission is to sequester one billion tonnes of CO2e on smallholder lands globally. To achieve this at scale, Varaha utilizes a tech-driven approach to Measurement, Reporting, and Verification (MRV). By employing remote sensing, satellite imagery, and soil testing, the company can provide corporate buyers with a high degree of confidence that the carbon sequestration they are paying for is actually occurring.
The partnership with GSK provides Varaha with the long-term capital needed to scale its operations. Moving from 42,000 hectares to 50,000 hectares and beyond requires significant investment in local infrastructure, farmer training, and machinery. Long-term off-take agreements, like the one signed by GSK, are essential for project developers to secure the financing necessary for such expansion.
Broader Implications for the Global Biopharma Industry
The GSK-Varaha deal serves as a blueprint for how global corporations can integrate climate action with their core mission. For the pharmaceutical industry, the link between a changing climate and the spread of infectious diseases, respiratory conditions, and heat-related illnesses is becoming increasingly clear. By investing in projects that improve air quality and water security, GSK is essentially engaging in "preventative medicine" at a planetary scale.
Furthermore, this agreement highlights the shifting maturity of the voluntary carbon market. In recent years, the market has faced scrutiny regarding the quality and permanence of carbon credits. By focusing on regenerative agriculture—a practice that provides tangible, ground-level benefits and utilizes rigorous MRV technology—GSK and Varaha are demonstrating what a "high-integrity" carbon project looks like in practice.
As more companies move toward their 2030 and 2040 climate milestones, demand for such projects is expected to skyrocket. The success of the Varaha project in Punjab and Haryana may encourage other multinational corporations to look toward the agricultural sector, not just as a source of emissions, but as one of the most powerful tools available for carbon sequestration and social upliftment.
Conclusion: A Model for Scalable Impact
The eight-year agreement between GSK and Varaha represents a sophisticated intersection of corporate responsibility, environmental science, and social equity. By transforming 50,000 hectares of Indian farmland into a carbon sink, the project addresses the immediate crisis of air pollution in Northern India while helping one of the world’s largest healthcare companies meet its rigorous climate targets.
As the project moves into its next phase of expansion, the data generated will provide valuable insights into the scalability of regenerative agriculture in the Global South. With 100,000 tonnes of carbon removal expected annually, the partnership stands as a testament to the power of cross-sector collaboration in tackling the dual crises of climate change and public health. For the thousands of farming families in Punjab and Haryana, the agreement offers more than just a cleaner environment; it offers a pathway to economic resilience in a rapidly changing world.
