Google signs its biggest rice-methane carbon credit deal with Indian startup Mitti Labs

Google has signed a four-year carbon credit agreement with Indian startup Mitti Labs targeting methane emissions from rice farming. The deal covers rice farms spanning three Indian states and will reach approximately 100,000 hectares at full scale, making it Google's largest rice-methane carbon credit purchase to date.

Mitti Labs operates a platform that helps rice farmers adopt methane-reducing agricultural practices. Rice paddies generate significant methane emissions through anaerobic decomposition in flooded fields. By working with farmers to implement techniques like alternate wetting and drying, Mitti Labs quantifies and monetizes the emissions reductions, which Google then purchases as carbon offsets.

The scale of this agreement reflects Google's aggressive carbon neutrality targets. The tech giant has committed to operating on carbon-free energy by 2030 and reaching net-zero emissions across its entire value chain by 2050. Carbon credits from verified emissions reduction projects like Mitti Labs fill the gap between direct decarbonization efforts and residual emissions Google cannot yet eliminate.

For Mitti Labs, the partnership validates its business model and provides revenue certainty. The startup has built software that tracks farming practices using satellite imagery, ground sensors, and farmer-reported data to verify methane reductions meet international carbon accounting standards. This creates a pipeline of bankable carbon credits that corporations and financial institutions can purchase to offset their own emissions.

India's agricultural sector accounts for roughly 14 percent of the country's greenhouse gas emissions, with rice cultivation a major contributor. Methane from rice paddies represents a significant climate challenge in a nation that produces over 100 million tons of rice annually. Mitti Labs' approach addresses this by working directly with smallholder and medium-scale farmers who form the backbone of Indian rice production.

The deal also reflects growing corporate appetite for nature-based carbon solutions. Technology companies face pressure from investors, employees, and regulators to demonstrate genuine climate action. Carbon credits from verified agricultural projects offer a scalable pathway to offset emissions while supporting farmer income in developing economies.

Mitti Labs competes with other agricultural carbon credit platforms including Nori, Indigo Ag, and Regrow Ag. However, its focus on Indian smallholder farmers and rice cultivation gives it geographic and crop-specific advantages. The company has raised funding from venture investors and has built relationships with state agricultural extension services, positioning it to capture a significant portion of India's rice farming base.

Google's partnership also signals confidence in carbon credit market standards and verification methodologies. The company works with third-party auditors to ensure credits represent real, additional, and permanent emissions reductions. As carbon markets mature and regulation tightens, buyers like Google increasingly demand transparent, verifiable projects.

The four-year timeline provides Mitti Labs with runway to scale operations across the three states while demonstrating impact to other potential buyers. Success here could open doors with other Fortune 500 companies, impact investors, and development finance institutions seeking exposure to high-quality agricultural carbon credits.
