Working together to ensure reliable, affordable and clean energy
Energy Efficiency banner Energy efficiency: Indicators

Energy efficiency indicators are an important tool for analysing the interactions among economic and human activity, energy use and CO₂ emissions. Many IEA member countries already employ energy indicators, a set of disaggregated measures of how energy is used. The IEA role is to assist and co-ordinate countries’ efforts through the maintenance of transparent international databases, the development of state-of-the-art energy indicators and collaboration with other international organisations.

The IEA has since 1997 developed a series of energy indicators to study energy-use developments and analyse factors behind changes in energy use and CO₂ emissions. Energy indicators (and the underlying databases) reveal key relationships between energy use, energy prices and economic activity. This insight is crucial when assessing and monitoring past and present energy policies, and for designing effective future action. This work on indicators also aims at increasing the transparency, quality, completeness and timeliness of energy-related data.
