ENERGY CONSUMPTION
Across all IGO managed operations, a total of 902,733 GJ
of energy was consumed in FY2015 and 152,397 GJ of
energy was produced. During the 2014 financial year, IGO
consumed 948,071 GJ, this is a 5% reduction in energy
consumption since last year.
Energy consumption at IGO occurs primarily at the two
active operations, Jaguar and Long. Jaguar has two
main areas of energy consumption diesel (for all vehicles
and machinery on site. At Long Operation, the energy
consumption areas are diesel (for the mining fleet) and
electricity use, which is taken from the grid. Explorations
have a low amount of energy use, with only diesel use in
vehicles and drill rigs.
The Long Operation consumed a total of 171,419 GJ
in FY2015. The Jaguar Operation consumed a total of
709,643 GJ in FY2015 and IGOs small facilities consumed a
total of 21,672 GJ. The figure below shows the percentage
contribution of each identified ‘facility’ to the total amount
of energy consumed.
GREENHOUSE GAS EMISSIONS
Greenhouse Gas Emissions (GHG) emissions and resulting
global climate change is considered one of the most
important issues in global environmental management.
Whilst IGO’s emissions are all but trivial in comparison to
other mining and industrial emitters, we understand that
we have a part to play. The total of Scope 1 and Scope
2 GHG emissions for all IGO facilities for 2015 was 53,957
tonnes (CO2-e). The main source of GHG for IGO is the
consumption of fuel at Jaguar and Long. Both sites have
taken steps to reduce GHG emissions. Jaguar Operation
installed a CNG-fuelled power plant to reduce diesel
consumption and Long Operation is using 5% biodiesel
blend for its mining fleet. This has resulted in a 4%
reduction in greenhouse gas emissions which is equal to
2,229 tonnes (CO2-e) since last financial year.
The figure below shows the breakdown of IGOs total
greenhouse gas emissions into the percentage of Scope
1 and Scope 2. To clarify, Scope 1 emissions are direct
emissions produced directly from sources that are owned
by IGO (e.g. fossil fuels burned on-site and in company
owned vehicles). Scope 2 emissions are indirect emissions
produced by the generation of electricity off-site and
purchased by the company.
