A comparison of farm-level greenhouse gas calculators in their application on beef production systems

This study highlights the differences between estimates produced by these tools, and explores the reasons behind them. Of relevance to users is the finding that even where farm-level estimates appear similar between tools, the composition of these estimates can vary. As such, different tools respond differently to system changes. In highlighting and exploring the impacts this can have, the conclusions of this study provide a key reference point for tool users and developers.
