Scope 2 greenhouse gas (GHG) emissions Emission of greenhouse gas, in relation to a facility, means the release of greenhouse gas into the atmosphere as a direct result of one or more activities that generate electricity, heating, cooling or steam that is consumed by the facility but that do not form part of the facility. These are emissions bought in from third parties. SF6 Stock Emissions of sulphur hexafluoride from gas insulated switch gear and circuit breaker applications. SI Serious injury A lost time injury where: –– The injured person is off work for more than two calendar weeks; or –– Involves unconsciousness arising from inhalation of fumes or poisonous gases; or asphyxiation due to lack of oxygen or displacement of oxygen by an inert gas; or –– Results from an accident, including fuming, arising from the use of explosives or blasting agents. Social licence to operate The level of acceptance a population or community has for an operation, company or industry. SPI Serious potential incident Incidents where the likely potential outcome is a fatality, permanent disabling injury, or irreversible or widespread health impacts. Usually there are no critical controls remaining to prevent impact to people, and the actual outcome is dependent on chance. Stakeholder A person or group that is influenced by, or can influence, an organisation. Sustainable development Development that meets the needs of the present without compromising the ability of future generations to meet their own needs. Sustainable development typically encompasses the three dimensions of economic, environmental and social. It refers to broader environmental and societal interests, rather than to the interests of specific organisations. SWIS South West Interconnected System of Western Australia SWIS is an electricity provider sourcing energy from a wide range of sources, including wind farms, solar and other renewables. t Metric tonnes TCFD Taskforce on Climate-related Financial Disclosures Tropicana Operation Tropicana Gold Mine that is 30 per cent owned by IGO and 70 per cent owned by AngloGold Ashanti Australia under the Tropicana Joint Venture agreement. TRIFR Total reportable injury frequency rate Many companies, including IGO, differentiate between total recordable injuries and total reportable injuries and the associated frequency rates. In Western Australia, total reportable injuries are defined by law, in that they include lost time injuries and reportable restricted work injuries. The frequency rate is calculated by the number of lost time and restricted work injuries / total hours worked (manhours) x 1,000,000 TSF Tailings storage facility WAD Weak acid dissociable Waste rock The sub-grade rock displaced during underground or surface mining operations Water consumption Defined in the GRI Reporting Standards as the sum of all water that has been withdrawn and incorporated into products, used in the production of crops or generated as waste, has evaporated, transpired, or been consumed by humans or livestock, or is polluted to the point of being unusable by other users, and is therefore not released back to surface water, groundwater, seawater, or a third party over the course of the reporting period. For the Nova Operation this includes total water in product, water in paste, water in tailings, water discharged to irrigation area, and evaporation. Water discharge Defined in the GRI Reporting Standards as the sum of effluents, used water, and unused water released to surface water, groundwater, seawater, or a third party, for which the organisation has no further use, over the course of the reporting period. Water withdrawal Defined in the GRI Reporting Standards as the sum of all water drawn from surface water, groundwater, seawater, or a third party for any use over the course of the reporting period. Workers’ compensation Payments required by law to be made to an employee who is injured or disabled in relation to work. IGO SUSTAINABILITY REPORT 2019 — 99
