According to the report, the 199 companies have already implemented, or committed to implement, emissions reductions equivalent to 0.7 per cent of 2006–07 levels (3.9 million tonnes of CO2-e per year). This would have the same effect as taking approximately 1.1 million cars off the road.
The energy efficiency activities undertaken include addressing fixed energy use, waste heat recovery and management, improved control systems, changing production or processing methods, and measurement and monitoring.
The sub-sector with the highest level of possible energy savings was ferrous metals and alumina production. Companies favoured energy efficiency measures with payback periods of less than two years and 80 per cent of projects that have already been implemented fall into this category.
“The 199 reporting corporations play a major role in Australia’s economy,” Minister Ferguson said.
“They directly employ hundreds of thousands of Australians in regions and communities all across the country.”
