Global Livestock Environmental Assessment Model - Summary

Ask a Question

  • This summary provides explanatory text and infographics explaining the global and national data, maps, and charts about the greenhouse gas emissions from livestock production. 
  • Emissions by animal species, source, and food product are also provided. 
Teaching Tips


  • This is a comprehensive document that students can use as a reference, with informative and useful infographics.
  • It helps students understand the data represented in the GLEAM tool.

Additional Prerequisites

  • Students should know how to read graphs and pie charts.


  • Students could use this summary to create a list of animal foods that would be the most climate-friendly and look at this article and video for the most climate-friendly foods available.
  • Students could investigate starting a Meatless Monday program at home or at school and create posters or informative media posts to educate others about the topic.
  • Advanced students could use this data to connect deforestation with food production in certain regions.
  • Students could investigate the staggering decline in wild animals as compared to the huge populations of livestock animals and humans. Have students think about how they can connect this to sustainability.
Scientist Notes
This resource describes the Global Livestock Environmental Assessment Model (GLEAM), which is used to study the emissions from animal agriculture across the globe. This resource is rather technical but provides good descriptions of the terminology used and sufficient resources (via various tabs) to understand what is presented. This resource is best suited for older students and can serve as a good example of the types of information used in complex models. This resource is recommended for teaching.
