SUSTAINABILITY REPORT 2015

Energy used, and associated CO 2e
and Scope 3 emissions for the year
were slightly less than in FY2014 due
to a reduction in electricity and diesel
use. This was partially offset by an
increase in petrol use in the fleet cars.
The majority of the savings in electricity
came from the hatcheries as a result of
reduced biomass produced in FY2015.
The reduction in diesel use came
predominantly from the marine farming
sites. One of the contributing factors
was the reduction of 41 baths across
the south east as a result of our
Selective Breeding Program (SBP)
together with improved husbandry. With
each bath using approximately 400 litres
of diesel and 200 litres of petrol, this
improvement has saved an estimated
915 GJ of energy.
A slight reduction in the energy used
to transport goods to market was
experienced due to a lower volume
of goods transported via air freight.
Despite this, air freight remained the
largest contributor to transport related
energy use. There was also a slight
increase in energy used in feed and
processing due to higher volumes of
feed use and fish production in FY2015.
