New NAMEA-based normalisation reference for Europe year 2000 Presentation for LCM2007 - the 3rd International Conference on Life Cycle Management, Zürich, 2007.08-27-29 Marianne Wesnæs & Bo Weidema 2.-0 LCA consultants
Construction of the new normalisation reference Data basis: – Input-Output tables at 60 industry level from 20 EU countries – Emission statistics for 50-70 % of total economic output (most for CO 2 , least for e.g. CO, PM, Pb) Extrapolation of emission coefficients (e.g. CO 2 /EUR) to countries not covered
EUROSTAT Input-output tables Covered Not covered Austria Italy Czech Republic Belgium Ireland Latvia Germany Malta * Lithuania Denmark Netherlands Luxembourg Estonia Poland Bulgaria Spain * Portugal Romania France Sweden Cyprus Finland Slovenia More than 98% of Greece Slovakia * total economic Hungary United Kingdom * output for EU-27 is * Supply-Use tables covered
Data for emissions from National Statistics Air emissions Carbon dioxide, Carbon monoxide, Methane, Ammonia, Dinitrogen monoxide, Nitrogenoxides, Sulfur dioxide, NMVOC, Particulates, Lead Water emissions Nitrogen, Phosphorus Coverage: From 8 National Statistics: DE, DK, ES, HU, IT, NL, SE, GB
Additional Data Air emissions from UK National Statistics Arsenic, Cadmium, Chromium, Copper, Mercury, Nickel, Selenium, Vanadium, Zinc Soil emissions from EIPRO Antimony, Arsenic, Atrazine, Barium, Cadmium, Carbaryl, Chromium, Cobalt, Copper, Lead, Mercury, Nickel, Phosphorus, Selenium, Zinc Import Import included by the use of the US NAMEA database (CEDA 3.0 by Suh, 2003)

Advantages of the new normalisation reference • Consumption perspective: Corresponds to LCA perspective (= LCA result for the sum of all products consumed in EU-27) • More frequent updating: In principle annuallly, since IO-data and most of the emissions statistics are available at annual intervals.
Uncertainties • Extrapolation of emissions from 50-70% to 100% – validated against EU-27 totals from (e.g. UNFCCC for CO 2 ) • Lacking emissons data – surprisingly small difference to RIZA/CML also for toxicity => mainly a problem if you have a speciality product with good data for toxic substances that are not in the normalisation reference
