 |
| Australian Standards (AS) |
National benchmarks for products and services. |
|
| Average Time Lost Rate (ATLR) |
An indicator of the average time lost for each lost time injury. The ATLR provides a measure of the severity of occurrences. It is calculated by dividing number of days lost by the number of LTIs. |
|
| Bank Cubic Metre (BCM) |
A bank cubic metre is a measure of overburden removed in mining operations. |
|
| Bank Cubic Metre Equivalent (BCMeq) |
A bank cubic metre equivalent is a measure of both coal produced and overburden removed in mining operations. |
|
| Carbon neutral |
A status where a company’s direct and indirect greenhouse emissions are reduced, with the remainder being offset by the purchase of emission credits. |
|
| COAL21 Fund |
A joint Government/industry research fund directed towards developing methods for reducing carbon emissions from coal use |
|
| CO2e |
carbon dioxide equivalent, a method for converting the global warming capacity of all greenhouse gases to a standard unit of carbon dioxide’s warming potential |
|
| DEC |

|
| DoCEP |
Department of Consumer and Employment Protection, a Western Australian Government Department inter alia involved in regulating dangerous goods and major hazards laws |
|
| EBIT |

|
| FESA |
The Fire and Emergency Services Authority of Western Australia. |
|
| Fugitive emissions |
Generally deliberate but not fully controlled emissions that typically result from leaks from pumps, pipes and valves. For example methane emitted from coal mine seams and vapour emitted when petroleum storage tanks are filled. |
|
| Gigajoule |
Unit of energy equivalent to 1,000,000,000 joules. |
|
| Greenhouse gases |
Gases such as carbon dioxide, methane and nitrous oxide which contribute to retention of heat in the earth's lower atmosphere |
|
| Greenhouse Challenge Plus |
The federal government’s programme of cooperation between industry and government to reduce Greenhouse emissions through voluntary action. |
|
| International Organisation for Standardisation (ISO) |
ISO publishes internationally-agreed standards covering areas such as quality management (the ISO 9000 series), environmental management (ISO 14000) |
|
| Liquefied petroleum gas (LPG) |
A combination of predominantly propane and butane extracted from natural gas or as a by-product of petroleum refining. |
|
| Liquefied natural gas (LNG) |
Comprising predominantly methane, it is produced from natural gas that has been purified, refrigerated and condensed to liquid form. |
|
| Lost Time Injury (LTI) |
An LTI is any work injury which causes absence for one day or a shift or more. |
|
| Lost Time Injury Frequency Rate (LTIFR) |
The main calculation we use to measure workplace safety performance. It is calculated by dividing the number of LTIs by total hours worked, multiplied by one million. |
|
| Mwh |
megawatt hour, a standard unit of electricity consumption |
|
| National Packaging Covenant |
An agreement between the packaging supply chain industry and governments which sets guidelines covering the manufacture, supply, distribution, consumption and recovery/recycling of post-consumer packaging. |
|
| National Pollutant Inventory (NPI) |
An Australian internet database designed to provide the community, industry and government with information on the types and amounts of certain substances being emitted to the environment. The NPI contains data on certain priority substances which are emitted to the environment. The substance list was determined by consideration of health and environmental risks in Australia. The NPI uses standard assumptions, in part, to calculate potential emissions we cannot measure or have difficulty measuring and, accordingly, data reported to the NPI may differ from point source emissions contained in this report. More information can be found on the NPI website www.npi.gov.au. |

| Overburden |
Unmineralised material overlaying coal deposits or ore bodies. |
|
| Rehabilitation |
Treatment of disturbed areas to achieve a level of stability equal to that which existed before or to an alternative acceptable form. |
