Greenhouse Gas Emissions
CSR’s operations, in common with the industries in which we operate, are energy intensive.
For the period 1 July 2007 to 30 June 2008, greenhouse gas emissions from CSR’s majority owned businesses were 1,389,819 tonnes of CO2-e. The scope 1 (direct) tonnes of CO2-e in Australia was 713,378 tonnes. While for the same period, the scope 1 (direct) greenhouse gas emissions of CSR’s majority-owned businesses operating outside Australia was 148,740 tonnes. Direct or scope 1 emissions are derived from sources within the plant or factory boundary.
The scope 2 (indirect) tonnes of CO2-e emitted in Australia was 467,454 tonnes. For the same period, the scope 2 (indirect) greenhouse gas emissions of CSR’s majority-owned businesses operating outside Australia was 60,247 tonnes. Indirect or scope 2 emissions are associated with the consumption of imported electricity, heat or steam.
CSR asked Ernst and Young to provide limited assurance that its greenhouse gas data was fairly presented in all material aspects. Ernst & Young’s limited assurance statement on CSR’s total Scope 1 and 2 greenhouse gas emissions is provided in the Limited Assurance section of the report.
CSR will report its 2008/9 greenhouse gas inventory under the Federal Government’s National Greenhouse and Energy Reporting framework.
For the same period CSR’s total energy use was 7,577,012 gigajoules, with natural gas and electricity, together with bagasse (renewable fuel) being the major energy sources.
To reduce its energy and greenhouse footprint, CSR is actively identifying greenhouse gas abatement opportunities throughout its business operations.
Energy Efficiency Opportunities
CSR is a participant in the Federal Government’s Energy Efficiency Opportunities Program and is required to report on assessments undertaken under the program. In CSR’s case, all assessments were undertaken on sites which have energy use greater than 500,000 gigajoules. CSR’s report can be found here.
Mandatory Renewable Energy Target (MRET)
This is a federal scheme that places a legal liability on wholesale purchasers of electricity to contribute towards an additional 9,500 GWh of renewable energy per year by 2010.
MRET uses Renewable Energy Certificates (RECs) to provide incentives for the development of renewable energy sources.
During YEM08, CSR Sugar generated sufficient renewable electricity for the creation of 281,214 RECs, or 5% of Australia’s Mandatory Renewable Energy Target. This is equivalent to taking 60,000 cars off the road, or enough renewable electricity to supply approximately 24,000 homes with power for a year.
CSR is actively identifying greenhouse gas abatement opportunities throughout its business operations.
Case Study
REDUCING ENERGY USE AND INCREASING ENERGY AWARENESS AT VIRIDIAN, WETHERILL PARK, NSW
The Viridian site at Wetherill Park, NSW has shown that simple measures and education can go a long way in reducing energy use.
A program to inform team leaders about the importance of energy reduction on site began in early 2008. Team leaders are in the best position to pass this information onto the majority of employees on site and to create an attitude towards saving energy, though team briefing sessions, known as “tool box talks“, that are held at the beginning of each shift.
At the same time, an operator checklist was developed for turning off all machines, lights & all other electrical equipment at the end of each shift to conserve energy. Since this checklist was implemented average monthly electricity consumption has decreased by 19% compared to the previous year. Overall, specific energy efficiency has improved by 6%, from 5.4 kWh/m2 for production to 5.0 kWh/m2.
Case Study
ENERGY REDUCTION AT BRADFORD INSULATION, INGLEBURN, NSW
During YEM08, Bradford Insulation undertook a project to increase the percentage of recycled glass used in the manufacture of Bradford Gold and other glasswool insulation products to 80%.
Recycled glass requires less energy to melt than sand, which is an alternative raw material for glasswool insulation. At commencement of the project, Bradford Insulation was using 60% recycled glass in the manufacturing process, constrained by a shortage in the particular type of glass used.
In order to increase the use of recycled glass to 80%, another source of recycled glass would have to be found. Bradford Insulation began working with new suppliers to establish a container glass recycling process which would meet its requirements. In order to be able to use recycled container glass, storage facilities had to be built on site at Ingleburn. At the same time, energy metering equipment was also upgraded.
The storage facilities were in place by June 2007 and recycled glass usage was progressively increased to 80% over the next 12 months. During the same period, specific energy usage dropped by 10%. As the new source of glass raw materials has been secured, Bradford Insulation will be able to sustain this level of energy savings indefinitely.
Case Study
REDUCING CARBON EMISSIONS IN THE BURDEKIN REGION SUGAR MILLS
In YEM07, CSR Sugar began a program in the Burdekin Region in North Queensland to replace cane locomotive engines with new high efficiency engines.
The program started modestly in YEM07, with two engines being replaced, stepping up to six in YEM08. The six cane locomotive engines that were replaced having saved CSR Sugar approximately 150,000 litres of fuel during the crushing season.
This is a reduction in carbon dioxide emissions of more than 400 tonnes per year.
This program is ongoing with five engines already replaced during the current year. The program is also being run in CSR Sugar’s other milling regions.
