Countries are Adopting Ambitious Targets
� EU20-20-20 programme by 2020
� China Reduce CO2 intensity by 40-45%
between 2005 and 2020
� India Reduce CO2 intensity by 20%
between 2005 and 2020
� Are targets met?

� 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
At a country level
