Methane mitigation is a critical component of global climate action, requiring comprehensive strategies across key emitting sectors. To advance these efforts, the Center for Global Sustainability (CGS) launched the Global Methane Abatement Solutions Tracker (G-MAST)—a comprehensive, open-access database designed to support informed, evidence-based decision-making for methane reduction worldwide.
G-MAST systematically compiles and tracks an extensive compendium of technologies and strategies aimed at reducing methane emissions across key anthropogenic methane-emitting sectors:
- Energy (coal mining, oil, and gas)
- Agriculture (rice cultivation, enteric fermentation, and manure management)
- Waste (landfills and wastewater).
Built through a rigorous combination of expert-driven and machine-assisted data collection, the database tracks and synthesizes information from academic literature, policy reports, and industry publications to capture how each technology has evolved over time and been applied across different countries and contexts. Each entry includes detailed information, where available, such as technology descriptions, reduction efficiency, abatement costs, implementation regions, maturity levels, techno-economic data, and associated environmental and socioeconomic co-benefits.
“As the world seeks to limit global temperature rise and achieve net-zero emissions, addressing methane emissions remains a pivotal step in climate action,” said project lead Mengye Zhu, Assistant Research Professor and CGS China Program Co-Director. “By addressing existing data gaps in methane mitigation solutions, this database will offer researchers, policymakers, and other stakeholders access to a comprehensive, open inventory of methane mitigation technologies and strategies. This resource will enhance understanding of practical solutions and support future research and policy development.”
Recognizing the dynamic nature of methane mitigation advancements, we are committed to continuously updating G-MAST to incorporate new findings, emerging technologies, and evolving best practices after its publication. This resource will support researchers, policymakers, and industry stakeholders in identifying effective solutions for reducing methane emissions globally.
