Using Indicators to Calculate Reduction Potentials for CO2 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 savingsWhere the potential lies (countries and
processes) However, there are limitations to the use
of the indicators:Assess instantaneous technical potentialDo not take into account practical constraintsNot suitable for short-term target setting
But calculated potentials are easy to understand

Key Conclusions and Policy Messages Indicators are a powerful tool for analysing trends in
energy use and CO2 emissions, and calculating potentials for further savings
Results show the important role of energy efficiency in shaping patterns of energy use and CO2 emissions in IEA countries, but gains are often offset by other factors
Large potential for further energy and CO2 savings in many industries and power generation (and other sectors)
Sustainable development requires that CO2 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
