IEA’s energy efficiency indicators work
Produce meaningful cross-country analysis to provide guidance to policy-makers on: Underlying drivers (economic activity & structure, income, prices...)
Trends in energy use and CO2 emissions
Energy efficiency opportunities and progress
Policy effectiveness
Establish a harmonised framework for data collection and analysis Harmonisation => Comparability
Comparability => Understanding of global trends and drivers
Request from member countries to provide a common methodological framework
