Isometric has issued more than 97,000 certificates to climate technology company Mitti Labs for methane reductions achieved through rice-farming projects in southern India, marking the certification company’s first issuance of superpollutant credits.

The issuance comes as global methane concentrations reached a record in 2025, according to the World Meteorological Organization. Rice cultivation is a major source of the gas, producing about 1 billion tonnes of carbon dioxide equivalent annually, comparable to emissions from global aviation.

Most rice-related methane comes from flooded fields, where oxygen-depleted soil conditions encourage methane-producing microbes.

Mitti Labs promotes Alternate Wetting and Drying (AWD), a farming practice that involves periodically draining and reflooding rice paddies instead of keeping them underwater throughout the growing season. The company says the approach can reduce methane emissions by as much as 50% and water consumption by 40%, without lowering yields.

Its programs operate in Telangana, Andhra Pradesh, Karnataka and Odisha, with more than 100,000 farmers involved.

According to Mitti Labs co-founder Xavi Laguarta, corporate buyers are broadening their portfolios to include rice methane reduction.

The certificates were independently verified under Isometric’s Rice Methane Reduction Protocol. Each represents one tonne of carbon dioxide equivalent (CO2e) emissions avoided. Isometric used its Certify platform to automate checks and calculations, with supporting evidence and data published on its public registry.

“As demand for superpollutant reductions grows, it’s critical that every certificate represents a tonne of emissions that was actually reduced,” said Isometric Chief Science Officer Stacy Kauk.
