For breaker facilities, eggs arriving at the facility gate accounted
for, on average, 98% of overall supply chain emissions associated
with production of unpackaged, pasteurized liquid eggs (Table S8,
Fig. 7). Due to large differences in reported energy, water, and
refrigerant use, associated facility-level emissions were similarly
variable. For example, emissions related to facility energy use varied
from as low as 51.8 kg CO2-e per tonne of liquid eggs produced
to as high as 174 kg CO2-e. This difference suggests opportunities
for improved energy use efficiency for participating breaker facilities,
or possible data reporting anomalies. Emissions related to
water and refrigerant use were trivial
