13 ORIGIN ENERGY FY2017 SUSTAINABILITY PERFORMANCE DATA 13 GLOSSARY 2 C scenario (2DS) An energy system deployment pathway to facilitate an emissions trajectory consistent with at least a 50 per cent chance of limiting average global temperature increases to 2 C, by limiting the total emissions between 2015 and 2100 to 1,000 Gt CO 2. 2P reserves The sum of Proved plus Probable Reserves. Probable Reserves are those reserves which analysis of geological and engineering data indicate are less likely to be recovered than Proved Reserves but more certain than Possible Reserves. There should be at least a 50 per cent probability that the quantities actually recovered will equal or exceed the best estimate of Proved Plus Probable Reserves. AEMO Australian Energy Market Operator (AEMO) is the body corporate responsible for the administration and operation of the wholesale national electricity market in Australia in accordance with the National Electricity Code. Aquifer injection Process of recharge of purified water to suitable aquifers. Aquifer interconnection Any mechanism by which a pathway between two aquifers is formed. This can be natural, where aquitards separating two aquifers become thin or nonexistent or a geological fault connects the aquifers, or it can be man-made via mechanisms such as historically uncemented well casing. Ash dam A pond used for disposal of coal ash generated from the burning of coal at power plants. Beneficial use of CSG water The reuse or recycling of waste water produced during the coal seam gas extraction process in a way that protects the environment and maximises its productive use as a valuable resource. Brine A residual saline solution derived from the water treatment process. Coal Combustion Product (CCP) By-products generated from burning coal in coal-fired power plants. Collective bargaining agreement Defined under the Fair Work Act 2009 as the process where employers, employees and bargaining representatives (including employee organisations) bargain for a collective agreement made at the enterprise level. Compensation and Conduct Agreement An agreement negotiated between companies and landholders setting out details of how access rights will be exercised and landholders compensated. A Compensation and Conduct Agreement (CCA) records the compensation the petroleum authority holder will pay to a landholder to compensate for the activities it carries out on the land and that have an impact on the land, the landholder s business or how the landholder uses the land. A CCA also records how the petroleum authority holder will conduct itself when it enters the land to conduct activities on the land. Consequence rating serious and above (environmental) An environmental rating that includes medium long term reversible impacts to low risk or listed species, habitats, ecosystems or areas of cultural significance; extensive long term partially reversible damage to vulnerable species, unique habitats, ecosystems or areas of cultural significance; or extensive permanent damage to endangered species, habitats, ecosystems or area/s of cultural significance. Consequence rating serious and above (safety) A safety rating that includes injury or illness to one or more persons resulting in a fatality, permanent partial or total disability, life threatening illness, hospitalisation, five or more days lost time or alternative/restricted duties for one month or more.

Environmental authority Authority granted under the Queensland Environmental Protection Act 1994 which imposes conditions to mitigate environmental impacts associated with approved activities. Fugitive emissions Fugitive emissions are the gases that leak or are vented or flared during the extraction, production, processing, storage, transmission and distribution of fossil fuels such as coal, crude oil and natural gas. They can also be released from the landscape. The Australian regulatory definition for fugitives emissions, which has been applied to this report including for New Zealand, includes flaring but excludes landscape emissions. GHG emissions Greenhouse Gas emissions. A greenhouse gas primarily refers to carbon dioxide, methane, nitrous oxide, sulphur hexafluoride, hydrofluorocarbons and perfluorocarbons. GHG emissions intensity The level of GHG emissions per unit of economic activity. Green Gas An Origin product where an equivalent amount of greenhouse gas emissions from a customer s natural gas use is offset through Origin Energy s independently audited Carbon Reduction Scheme.

Hydraulic fracture stimulation Creation and enhancement of fractures in rock using a gas or fluid injected at high pressure. It increases the ability of water and gas to flow through a coal seam, which enhances the removal of water and extraction of CSG. IEA 450 Scenario An energy pathway consistent with limiting the global increase in temperature to 2 C by limiting the long term concentration of CO 2 to 450 parts per million (a higher peak may occur around 2050). IEA New Policies Scenario An energy pathway consistent with the intended nationally determined contribution submissions from countries prior to COP21. Integrated Gas Origin s Integrated Gas business is focused on finding and developing oil and gas (conventional) and coal seam gas (unconventional) reserves across Australia and New Zealand. Interaction Net Promoter Score (NPS) How customers feel about Origin after a recent interaction or contact with Origin. It provides a diagnostic evaluation at the most granular level and primarily looks at tactical process and service improvements. kt One kilotonne equals 1,000 tonnes. LNG Liquefied Natural Gas. LPG Liquefied Petroleum Gas. LTIFR Lost Time Injury Frequency Rate. Make good agreement An agreement between a landholder and petroleum tenure holder that implements measures to make good potential impairment of private bore water supplies that result from CSG water extraction or gas impairment. National Electricity Market (NEM) The wholesale electricity market for the electrically connected states and territories of eastern and southern Australia Queensland, New South Wales, the Australian Capital Territory, Victoria, South Australia and Tasmania. Native title Native title is a form of land title that recognises the unique ties some Indigenous groups have to land. NGER National Greenhouse and Energy Reporting scheme. NOx Oxides of nitrogen (NOx) a mixture of gases that are composed of nitrogen and oxygen. Paris Agreement An agreement within the framework of the United Nations Framework Convention on Climate Change (UNFCCC) that sets out a global action plan to put the world on track to avoid dangerous climate change by limiting global warming to well below 2 C. PJ A petajoule is equal to one million gigajoules.

15 ORIGIN ENERGY FY2017 SUSTAINABILITY PERFORMANCE DATA 15 PJe A petajoule equivalent an energy measurement Origin Energy uses in its Annual Report to represent the equivalent energy in different products so the amount of energy contained in these products can be compared. The factors used by Origin Energy to convert to PJe are: one million barrels of crude oil = 5.8 PJe; one million barrels of condensate = 5.4 PJe; one million tonnes of LPG = 49.3 PJe; one TWh of electricity = 3.6 PJe.
