Milestone carbon credit methodology for rice launched with help from IRRI

LOS BANOS, Philippines (26 July 2023) – This July, Gold Standard launched a new carbon credit methodology for reducing greenhouse gas emissions in rice cultivation. Developed with inputs from the International Rice Research Institute (IRRI), this new methodology,can help farmers reduce emissions from rice fields, as well as open a new source of income from the sale of carbon credits, incentivizing sustainable rice farming.

Globally, rice cultivation is responsible for around 10% of total man-made emissions of methane, a potent greenhouse gas. Most of these emissions are produced by bacteria in the soil of flooded rice paddies and not by the rice plants themselves. Research and trials have shown that reducing and managing water use can significantly reduce emissions of methane from rice fields by as much as 50%.

The Methodology for Methane Emission Reduction by Adjusted Water Management Practice In Rice Cultivation comprises instructions to estimate baseline and project emissions, as well as monitoring guidelines and requirements for stratification of reference and project fields. Building on recent efforts to scale carbon market access for smallholder farmers , this methodology can be applied to large, small, or micro-scale projects globally, and can provide a cost-effective, accessible, and practical pathway for smallholder farmers to monetize emissions reductions through carbon credits, increasing the likelihood of achieving carbon reduction outcomes at scale.

Key IRRI scientists involved include climate specialists Dr. Bjoern Ole Sander, Dr. Katherine Nelson, and Dr. Reiner Wassmann. They contributed technical inputs, particularly on the stratification categories that enable grouping based on patterns of cultivation conditions. This improvement addresses an important concern from the global community of the lack of guidance for field stratification that was not included in the previous methodology. Additionally,…
