Tools in the GLEAM ecosystem
GLEAM-X interactive web application
GLEAM-X interactive web application is a user-friendly tool that provides access to the Global Livestock Environmental Assessment Model (GLEAM), developed by the Food and Agriculture Organization of the United Nations (FAO). It applies the IPCC Tier 2 methodology to estimate the environmental impacts of livestock agrifood systems and applies a Life Cycle Assessment (LCA) approach, accounting for both direct on-farm emissions and indirect emissions along the production chain.
GLEAM-X interactive web application is designed for farmers, producers, policymakers, researchers, and other stakeholders. It enables the comparison of different livestock production scenarios and supports the assessment of projects and interventions at different stages, including ex-ante evaluations, monitoring during implementation, and ex-post impact assessments. The web application evaluates impacts related to animal husbandry, herd management, feed systems, manure management, energy use, and post-farm emissions, and quantifies changes in soil carbon sequestration resulting from improved grazing management practices.
The web application enables rapid, user-friendly calculations, scenario comparisons, and visualizations. For more detailed analyses, customized modelling, or the preparation of national greenhouse gas inventories, the full-featured GLEAM-X R package is recommended.
The development of GLEAM-X interactive web application was supported by the Federal Ministry of Agriculture, Food, and Regional Identity of the Government of Germany.
GLEAM-X R package
The GLEAM-X R package is an open-source modelling tool that leverages FAO’s GLEAM datasets and methodologies into the R programming environment, making livestock emissions analysis more accessible, transparent, and adaptable. By integrating official GLEAM data and methods, the package enables reproducible, flexible, and customizable modelling workflows.
The GLEAM-X R package broadens access to livestock emissions modelling, enabling users worldwide to apply standardized FAO methodologies while tailoring analyses to their specific contexts and needs.
Freely available on CRAN and GitHub, the GLEAM-X R package is accompanied by guidance materials and learning resources to facilitate its adoption by governments, researchers, and development partners.
GLEAM dashboards
Results from the latest version of GLEAM (using 2015 as a reference year) are accessible through our GLEAM dashboards, highly interactive web applications for visualization, analysis, and dissemination of data.
GLEAM v3 Emissions dashboard
This application allows aggregation and visualization of data related to livestock numbers, animal production, greenhouse gas emissions, and emission intensities by region, production systems, and source of emissions.
GLEAM v3 Emissions dashboard
GLEAM v3 Water Use dashboard
This application allows aggregation and visualization of data related to water use and water footprints in livestock agrifood systems, and considers water used for feed production, as well as direct water use for drinking water and service water.
