Outcomes from the 2025 meeting
The panel recommended all the proposed changes be made, with some minor adjustments (see minutes for details).
The panel agreed to the proposed accounting approach for low-methane sheep genetics but has requested information on the activity data for breeding values used as inputs to the model, including how their uncertainty depends on the emissions measurement sampling approach (refer to the meeting minutes for more details).
