5. STUDY COMMITTEE C3, System Environmental Performance 26 August 2008 Achievements Analysis of guidelines available at the beginning of the study –Sustainability Reporting Guideline (Global Reporting Initiative) V2 –Environmental Performance Indicator guidelines for the Australian Electricity Industry (ESAA) –Guidance notes on environmental benchmarking indicators for the electricity sector (EA) –Sustainability in the Electricity Supply Industry: Phase 1 Report (WSDBC). Analysis of guidelines available issued during the study (late 2006 and early 2008) –Sustainability Reporting Guideline (Global Reporting Initiative) V3 –GRI Electric Utility Sector Supplement – Draft version (GRI) –Sustainability Reporting Guidelines & Electric Utility Sector Supplement Pilot Version

6. STUDY COMMITTEE C3, System Environmental Performance 26 August 2008 References GRI V2 as best existing reference but as no Sector Supplement were available, the WG had to use others guidelines Issue of GRI V3 and a draft of the Electric Utility Sector Supplement late 2006: Indicators have to be reviewed, but 90 % of the work can be considered as valid. Issue of a combined version of GRI V3 and the Electric Utility Sector Supplement beginning 2008.

7. STUDY COMMITTEE C3, System Environmental Performance 26 August 2008 General comments Environmental indicators are specific to TSO, and have to be distinguished from those dealing with generation. For instance –Waste (radioactive waste or ashes vs PCB, iron,concrete...) –Emissions (NOx, SOx, CO2 vs SF6) –Significant spills (radioactive leaks vs oil leaks)  Important risk for TSO to have their environmental impacts hidden by Generation ones. Other indicators should apply (Economic and Social) whatever the company type (TSO, integrated utility, Genco...)
