Simulation reveals methane intensity and blue water footprint differences in diverse beef cattle breeds, suggesting significant environmental impact.

The methane intensity ranged from 0.59 kg to 0.85 kg of methane, demonstrating a notable variance among breeds.
Enteric methane emissions totaled 18 800 kg per year for the farm, highlighting the environmental burden of beef production.
The blue water footprint was estimated at 3285 kilolitres annually, reflecting substantial water use in cattle farming.
Further research is needed to validate the findings, emphasizing the importance of breed selection for sustainability.

Chabalala et al. (2025) studied this question.
