BlueScope Steel is a significant emitter of greenhouse gases at both its Port Kembla and New Zealand Steel facilities. This reflects the nature of the steelmaking process at these two integrated steelworks.
Of the greenhouse gases emitted by BlueScope Steel's operations in Australia, New Zealand, the Asia Pacific region, and the United States, about 75 per cent are emitted by the Port Kembla Steelworks.
Globally, BlueScope Steel's operations emitted approximately 14.5 million tonnes of carbon dioxide equivalent (CO2-e) in 2004/05, to produce 5.72 million tonnes of steel product. (Note: we also process a percentage of this steel into products).
BlueScope Steel's greenhouse gas emissions have remained relatively constant over recent years.
We use a greenhouse gas intensity index to calculate the volume of CO2-e emitted for each tonne of steel produced compared to a base year. A number less than 1 indicates an improvement in greenhouse gas intensity. The Company's greenhouse gas intensity in 2004/05 was 0.96, and it has remained relatively constant in recent years.
