EUROPEAN TOPIC CENTRE ON AIR AND CLIMATE CHANGE Comparison of EU and MS reference approach Energy workshop 24/25 June 2003 Bernd Gugele (EEA/ETC) Energy workshop 24/25 June 2003 Bernd Gugele (EEA/ETC)

EUROPEAN TOPIC CENTRE ON AIR AND CLIMATE CHANGE IPCC reference approach w Combustion related CO 2 emissions –Sectoral approach (bottom-up) –Reference approach (top-down) –Comparison sectoral/ref. approach w EU reference approach –Sum of MS reference approach –Calculate from Eurostat data w Experience from 2003 –Improvement needed w Combustion related CO 2 emissions –Sectoral approach (bottom-up) –Reference approach (top-down) –Comparison sectoral/ref. approach w EU reference approach –Sum of MS reference approach –Calculate from Eurostat data w Experience from 2003 –Improvement needed

EUROPEAN TOPIC CENTRE ON AIR AND CLIMATE CHANGE IPCC Eurostat ref. appr. (1) w New Cronos db, version October 2002 w Includes groups of certain fuels e.g. –Orimulsion  Residual fuel oil –Natural Gas Liquids  Crude Oil –Other Kerosene  Total Kerosene –Anthracite, Coking Coal  Other Bit. Coal –Sub-bit. Coal, Peat  Lignite –Solid, liquid, gas biomass  Biomass total w Calorific values –Country specific for primary solid fuels –Annual update for solid primary fuels –Average calorific values for secondary fuels + crude oil w New Cronos db, version October 2002 w Includes groups of certain fuels e.g. –Orimulsion  Residual fuel oil –Natural Gas Liquids  Crude Oil –Other Kerosene  Total Kerosene –Anthracite, Coking Coal  Other Bit.

EUROPEAN TOPIC CENTRE ON AIR AND CLIMATE CHANGE Main reasons for divergence w Austria –Carbon stored (AD + fraction) w Denmark –Apparent consumption solid fuels w Finland, Sweden –Apparent consumption liquid and solid fuels w Ireland –Apparent consumption liquid fuels; carbon stored w France –Carbon stored (AD + fraction) w Germany –Carbon emission factors (i.p. solid fuels) w Austria –Carbon stored (AD + fraction) w Denmark –Apparent consumption solid fuels w Finland, Sweden –Apparent consumption liquid and solid fuels w Ireland –Apparent consumption liquid fuels; carbon stored w France –Carbon stored (AD + fraction) w Germany –Carbon emission factors (i.p. solid fuels)

EUROPEAN TOPIC CENTRE ON AIR AND CLIMATE CHANGE Main findings w Reasons for diverging energy data –Exclusion of international aviation –Different calorific values: Mainly for secondary fuelsMainly for secondary fuels –Different basic activity data w Reasons for diverging CO 2 –Non-energy use Activity dataActivity data Fraction of carbon storedFraction of carbon stored –Use of country specific emission factors w Reasons for diverging energy data –Exclusion of international aviation –Different calorific values: Mainly for secondary fuelsMainly for secondary fuels –Different basic activity data w Reasons for diverging CO 2 –Non-energy use Activity dataActivity data Fraction of carbon storedFraction of carbon stored –Use of country specific emission factors
