AGL Energy Limited 72
Greenhouse footprint – supporting
information
Supporting information – Operational Footprint
Data preparation and boundaries
Greenhouse gas emissions, energy consumption and energy
production data reported as part of the AGL Greenhouse Footprint
have been prepared in line with AGL’s interpretation of the
National
Greenhouse and Energy Reporting Act 2007
(Cth) and supporting
regulations.
Notable exceptions are as follows:
>> Despite inclusion in the AGL Energy Limited 2012 annual
Report under the
National Greenhouse and Energy Reporting
Act
(Cth), greenhouse gas emissions, energy production and
energy consumption related to the Great Energy Alliance
Corporation Pty Limited facilities acquired by AGL on 29 June
2012 are excluded from AGL’s 2012 Operational Footprint
(since the acquisition occurred so late in the financial year). For
completeness, the emissions from the AGL Loy Yang Power
Station and associated facilities are reported separately to
the AGL 2012 Operational Footprint;
>> Energy consumption is included in the Operational Footprint
only if it is combusted or otherwise disposed or used in an
AGL operated facility. Energy that is ‘consumed’ by way of
transformation from one commodity to another, and renewable
energy sources (wind, water and solar) are not included in the
Operational Footprint consumption values;
>> All electricity production reported in the Operational Footprint
is presented on a ‘sent-out’ basis (i.e. excluding generation that
is consumed within the facility and is not sold to any market or
customer);
>> Oil and gas energy production is presented on a ‘sales’ basis, and
excludes any production used within the facility, or energy forms
that are transformed from one energy commodity to another;
>> Energy is not included in the Operational Footprint as either
consumption or production if the commodity is on-supplied to
another user without significant processing or transformation.
Reporting period
The data presented in the AGL greenhouse footprints for FY2012 has
been prepared for the reporting period 1 July 2011 to 30 June 2012.
Greenhouse gas emissions estimation methodology
The Operational Footprint has been estimated in line with the
National Greenhouse and Energy Reporting (Measurement)
Determination 2008 (as amended) published by the Commonwealth
of Australia for the FY2012 reporting year, and related guidelines.
Unless otherwise indicated, greenhouse gas emissions are the sum
of scope 1 and scope 2 greenhouse gas emissions, expressed in
tonnes of carbon dioxide equivalents (tCO
2
e).
Energy consumption and energy production measurement
The measurement of energy consumption and energy production
presented in the Operational Footprint has been carried out in line
with the National Greenhouse and Energy Reporting (Measurement)
Determination 2008 (as amended) published by the Commonwealth
of Australia (unless otherwise indicated and subject to the exceptions
noted above). Energy consumption and energy production are all
expressed in gigajoules (GJ), unless otherwise indicated.
Organisational boundaries
Greenhouse gas emissions, energy consumption and energy
production presented in the Operational Footprint have been
reported for the corporate group of AGL Energy Limited (the
parent company and its wholly owned Australian subsidiaries),
as determined in line with the
National Greenhouse and Energy
Reporting Act 2007
(Cth).
Operational boundaries
Greenhouse gas emissions, energy consumption and energy
production in the Operational Footprint have been reported for
facilities over which AGL has ‘operational control’, as defined in the
National Greenhouse and Energy Reporting Act 2007
(Cth), within
the organisational boundaries.
As noted previously, energy and greenhouse gas emissions for the
Loy Yang A Power Station and associated facilities are excluded from
the Operational Footprint for FY2012, although for completeness
this information has been provided separately.
