INTERNATIONAL ENERGY AGENCY Worldwide Trends in Energy Use and Efficiency Key Insights from IEA Indicator Analysis ENERGY INDICATORS © OECD/IEA Using Indicators to Calculate Reduction Potentials for CO 2 Emissions Use of BAT/BPT to assess potential in the industrial and electricity generation sectors These indicators are useful for showing: To what extent existing technology can achieve further savings Where the potential lies (countries and processes) However, there are limitations to the use of the indicators : Assess instantaneous technical potential Do not take into account practical constraints Not suitable for short-term target setting But calculated potentials are easy to understand

INTERNATIONAL ENERGY AGENCY Worldwide Trends in Energy Use and Efficiency Key Insights from IEA Indicator Analysis ENERGY INDICATORS © OECD/IEA Key Conclusions and Policy Messages Indicators are a powerful tool for analysing trends in energy use and CO 2 emissions, and calculating potentials for further savings Results show the important role of energy efficiency in shaping patterns of energy use and CO 2 emissions in IEA countries, but gains are often offset by other factors Large potential for further energy and CO 2 savings in many industries and power generation (and other sectors) Sustainable development requires that CO 2 emissions be decoupled from economic growth, this is possible but will require strong policy-action from Governments Urgent need for governments to enhance framework for monitoring end-use energy consumption and address the gaps in available statistical data
