Updates to Anaerobic Digestion Pathways for Animal Manure in R&D GREET 2025

Summary

Manure management from livestock and poultry in the U.S. is a significant source of greenhouse gas emissions, particularly methane, which has seen a substantial increase since 1990. To more accurately assess these emissions and support policies like the Renewable Fuels Standard, Argonne National Laboratory has updated the R&D GREET model. These updates refine the methodology for estimating emissions from anaerobic digestion pathways, including new data on animal populations, management practices, and methane conversion factors, with the refined model scheduled for release in R&D GREET 2025.
