In the study, a general energy performance evaluation methodology for industrial enterprises will be developed based on summary and analysis on energy performance evaluation methodologies and practices in APEC economies, to facilitate the implementation of EnMS, establish a long-term energy efficiency improvement mechanism as well as provide support for relevant energy efficiency programs.

According to materials investigation, five economies with their energy performance evaluation programs and a regional program are chosen as objects for the study, and they are:
- Canada
- China
- Japan
- Singapore
- USA
- ASEAN
