Premier Coal is a signatory to the
Australian Greenhouse Challenge and has a Cooperative
Agreement to 2005. Premier has reduced greenhouse emissions
per unit production by 50% since 1994.

Greenhouse performance at the Premier Mine is a function of
emissions from energy used in mining, coal processing and transport,
and a contribution from spontaneous combustion. Unlike many
coals, Collie coal has no associated methane, a major bonus.
Most of our greenhouse emissions are from the use of fuels
producing carbon dioxide. Percentage contributions to June
2003 were as follows:
- Diesel 61.9%
- Electricity 34.0%
- LPG 0.3%
- Explosives 0.5%
- Spontaneous Combustion 3.1%
- Petrol 0.2%
Since 1994, Premier Coal has reduced unit emissions by 50%
through a variety of initiatives including energy audits,
changed mining practices and equipment, reduced haulage distances,
higher efficiency motors, lighting control systems and sequestration.
Premier Coal has also established Eucalypt plantations on
all available private property that it has purchased in association
with the mining operation.
Premier Coal is a signatory to the Australian Greenhouse Challenge
with a program to reduce emissions by a further 18% by 2005.
Recent initiatives for this Challenge include:
- Truck tray lining to reduce carry back;
- Use of computer-based truck dispatch to
optimise fleet movements;
- Lighting control systems in the Maintenance
Workshop;
- Fuel additives;
- Fuel monitoring system; and
- Greater focus on spontaneous combustion controls.
