Provide guidance on when to apply which normalisation reference.
The calculation of the normalisation reference is documented in Annex 6.4.
It is, however, also possible to use the updated Danish normalisation reference, e.g.
Table 11.4 Normalisation reference and weighting factors for stratospheric ozone depletion.
The calculation of the aquatic eutrophication normalisation reference is shown in the table below.
The EU-15 normalisation reference is recommended for impact potentials located in Denmark and in Europe.
Further, the guideline is focused on choice of impact categories and choice of normalisation reference.
The EU-15 normalisation reference is between the global and the Danish normalisation reference. .
For regional impact potentials like nutrient enrichment, the EU-15 normalisation reference and the EU-15 weighting factor are recommended.
The normalisation reference and weighting factor for stratospheric ozone depletion are presented in Table 11.4.
The inclusion of the missing EU countries is not expected to change the resulting European normalisation reference significantly.
Table 5.1 Normalisation reference and weighting factors for stratospheric ozone depletion Hoffmann 2005; Busch 2005.
The report gives a detailed insight into the data sources andcalculation procedures that have been used in the calculation of each normalisation reference.
The normalisation reference is therefore calculated by taking the differences between high and low NOx areas into account.
As can be deduced from Table 11.6 andseen in Figure 11.4, the normalised result can vary with about 40%, depending on which normalisation reference is chosen.
It is recommended to use the EU-15 normalisation reference combined with EU- 15 weighting factor for nutrient enrichment.
The reason for choosing 1994 as reference year has been the relatively easy availability of compilations of data for most of the countries included in the EU-15 normalisation reference.
Below an example of applying the normalisation reference and weighting factor for a product(a refrigerator) is presented.
For regional impacts(acidification, photochemical ozone formation and nutrient enrichment) and local impacts(ecotoxicity, human toxicity)use the EU-15 normalisation reference as the base reference. .
The normalisation reference has decreased slightly since 1990 resulting in higher normalised global warming potentials.
Human toxicity is considered as a local as well as a regional impact and the EU-15 normalisation reference and weighting factors are recommended for impact potentials located in both Denmark and Europe.
The new normalisation reference includes normalisation reference at both the regional and local levels for the relevant impact categories.
The case used in the report is an example of this,where the generally recommended normalisation reference for EU-15 could be supplemented with the Danish normalisation references in a sensitivity analysis.
The normalisation reference for Denmark has decreased with about 20% since 1990 resulting in an increase of the normalised acidification potential.
For regional impacts(acidification, photochemical ozone formation and nutrient enrichment) and local/regional impacts(ecotoxicity, human toxicity)use the EU15 normalisation reference as the base reference. .
In the calculation of the normalisation reference for ecotoxicity, it has thus been the ambition to find the right order of magnitude.
Normalised GWP is the normalised global warming potential for the considered product GWP is the global warming potential for the considered product NormrefGWP is the normalisation reference for global warming.
Furthermore, the new set of normalisation references allows the user to choose a normalisation reference adjusted to a specific purpose.
For regional impacts(acidification, photochemical ozone formation and nutrient enrichment) and local impacts(ecotoxicity, human toxicity)use the EU-15 normalisation reference and weighting factor as the base reference. .
The EU-15 normalisation reference is less than half of the Danish reference probably due to significant differences in area distribution between land and water surface.
