Popis: Context Eggs, a dietary staple, are a low environmental-impact animal protein, although no quantified analysis has been published for the Australian egg industry. Aims This study determined baseline greenhouse-gas (GHG) emissions, fossil energy use, freshwater consumption, water stress, and land-occupation impacts for the Australian egg for 2020 and identified hotspots. Methods To understand the environmental credentials of the industry, an attributional life-cycle assessment was conducted using primary data collected from all major Australian production regions. Impacts were reported per kilogram of table eggs and per kilogram of shell- and protein-corrected eggs for cage (C), cage-free (CF) and free-range (FR) production. Monte Carlo analysis was used to assess uncertainty, and results are presented using the means and standard deviations. Key results Statistically significant (P
