Challenges
Reduced energy use due to decline
in sectoral intensities = Energy Savings
OF ENERGY USE
IN IEA COUNTRIES
Without energy savings and structural changes, 1998
energy use would have been twice as high
G8 Request
Identify promising areas for further
analysis of industrial energy
efficiency potentials
Develop new country level indicators
for industrial energy efficiency
Advise on policies and best practices
Expanded by IEA GB to include CO2

Focuses on key sectors
Focuses on key countries
Look at country trends
Try to compare country efficiencies
Does NOT cover materials
comparison/substitution potentials
 Each sector needs a tailor-made approach
 Detailed approach needed
 Balance data availability, level of detail and
acceptance

Industry Indicators Publication
content
 Written for a high-level audience
 Goal is to provide the best possible information on
current efficiencies & past trends on a country/region
level, by sector
 Focus on energy and CO2 emissions per unit of
physical product
 10 chapters, special attention for:





Iron & steel
Cement
Chemicals & petrochemicals
Pulp & paper
CHP
 Proposes multiple indicators: there exists no “true”
ranking
 Balance data availability and “correctness”

Insights
 70% of energy use in heavy industry, 30% in light
industry
 Iron & steel, chemicals and cement account for
75% of direct emissions
 Sectoral energy use and CO2 emission relevance
do not match
 80% of the growth in the past 10 years in China
 A gradual efficiency improvement over time in all
sectors in all regions
 Remaining energy efficiency potential 10-30%
 Energy efficiency is part of the solution
 Efficiency in DCs often higher than in OECD
countries
