This document is a summary that presents the best practices identified in a comprehensive RAP report on energy efficiency obligations (EEOs). Governments in various jurisdictions around the world have endeavored to improve end-use energy efficiency, and in some cases also achieve other objectives, by designing and implementing EEO schemes. These schemes require energy providers, such as electricity and gas companies, to meet quantitative energy saving targets through assisting their customers to implement end-use energy efficiency measures. The full report includes detailed case studies of 19 EEO schemes implemented in a range of jurisdictions around the world. This report summary includes a table that compares the key design parameters among the schemes covered in the full report. Adopting the best practices presented in the report summary should improve the effectiveness of EEO schemes in delivering cost-effective energy efficiency.
