Use of Environmental Life Cycle Impact Assessment for Power Generation Systems: Canadian Electricity Association Case Study

During 2003-2004, the Canadian Electricity Association sponsored a study to test the application of the environmental life cycle impact assessment on various power generation technologies, including, but not limited to, coal generation, wind power, natural gas, and hydropower facilities. This paper discusses the goal and scope of the study, key methodological issues, key findings, and policy implications of these pilot studies. Through the integration of advanced impact assessment techniques, the study provides a benchmark for similar studies including those of the western area power authority and suggests counterintuitive results for wind power and coal technology operations. Additionally, the application of the methodologies toward the development of the ASTM E06.71.10 draft standard and the UNEP/SETAC LCIA initiative will be covered
