Rice Methane Action Alliance (RMA)

Scaling Business-Driven Climate Action in Rice Agriculture

The Rice Methane Action Alliance (RMA) is a global, multi-stakeholder platform committed to accelerating the transition to low-emissions, climate-resilient rice production systems. Led by the WBCSD, RMA mobilizes business-driven solutions that reduce methane emissions, strengthen rural livelihoods, and support nature-positive outcomes.

 

By aligning corporate ambition with field-level action, RMA bridges the gap between technical guidance and real-world adoption, enabling measurable progress on climate, nature, and food system resilience.

Technical Guidance and Field-Level Uptake

As part of its commitment to actionable impact, the Rice Methane Action Alliance has developed a comprehensive Technical Guidance Report. This resource consolidates best practices, scientific evidence, and implementation frameworks to support the practical adoption of low-emission rice cultivation methods.

The guidance is designed for scalability, providing clarity for project developers, agribusinesses, and policymakers on how to implement mitigation practices effectively across diverse geographies. Early uptake of the guidance has already demonstrated:

  • Enhanced water efficiency and improved soil health
  • Reductions in methane emissions through field-tested approaches
  • Greater farmer resilience and livelihood outcomes
  • Improved access to climate finance through alignment with MRV frameworks

This resource underpins the Adopt pillar of RMA’s strategy, serving as a bridge between high-level ambition and on-the-ground action.

The Challenge
1.

The Challenge

Rice, a dietary staple for over half the global population, presents a significant, yet underappreciated, climate challenge. 

Flooded rice fields are a major contributor to global methane emissions, responsible for an estimated 10% of anthropogenic methane releases (World Bank, 2022). Given methane’s extremely high global warming potential, 84 times that of CO₂ over a 20-year horizon (IPCC AR6, 2023), its mitigation offers an unparalleled opportunity for immediate climate impact. 

These emissions stem from anaerobic decomposition processes in waterlogged fields and are shaped by a complex interplay of water management practices, organic inputs, soil composition, and climatic conditions. 

Reducing methane emissions from rice cultivation constitutes one of the most strategic and immediate levers for climate action within the agricultural sector, while simultaneously delivering a host of environmental and socio-economic co-benefits. 

The Business Case
2.

The Business Case

Transitioning to sustainable rice production systems is not solely an environmental imperative; it is also a compelling proposition for the private sector.

Through the Rice Methane Action Alliance, WBCSD harnesses:

• The influence of corporate leadership and global supply chains;
Harmonised Measurement, Reporting and Verification (MRV) standards; and
Innovative blended finance models to unlock and scale investment in sustainable landscapes.

This approach empowers companies to fulfil their climate and nature-related commitments, whilst fostering greater supply chain resilience and enhancing the well-being of farming communities.

The Solution

The Solution

Mobilizing and scaling up business-driven actions and co-investments to accelerate the transition tolow-emissions and resilient rice production systems that benefit farming livelihoods, food security,climate and nature. ​

Action Areas

The Alliance focuses on 3 prioritized action areas that engages corporate rice supply chains:

Action Area 1:

CONVERGE on defining low-emissions rice and MRV best practices

 

Harmonizing low-emissions and resilient riceguidance, disclosures,MRV & transition actionplanning.

 

Supported by the Global Methane Hub & Partners

Action Area 2:

ADOPTION to drive collective actions across value chain

 

Facilitating uptake of theTechnical Guidance, actionplan implementation andreporting, and promotinginnovative actions andknowledge-sharing acrossthe rice value chain. 

 

Supported by the Global Methane Hub & Partners

Action Area 3:

CO-INVEST to accelerate collective investments for low-emissions rice

 

Catalyzing public-private co-investment partnershipsacross the rice value chainin priority countries andlandscapes, incl. via SRLI. 

 

Priority countries identified to date include:China, India, Thailand, Vietnam,Bangladesh, Cambodia. 

 

Supported by WBCSD-involved initiatives with regional co-investment opportunities for rice incl. the Sustainable Rice Landscapes Initiative (SRLI) and its Blended Finance Facility for resilient rice in Asia.
