Use of Results: Current LCA vs. PEF Initiative
Issue Current Practise PEF Guide
Green Claims LCA study according to own interpretation of ISO 14044, no PCR document required.
EC wants a single market for green products. All future green claims (declarations) should be based on an PEF & PEFCR.
Green Claims w/ comparisons
Comparison new model vs. predecessor: each company may use its own LCA methodology.
PEFCR will become standard to be used for classical comparative assertions. Companies will loose flexibility here.
10
Use of Results: Current LCA vs. PEF Initiative
Issue Current Practice PEF Guide
End of Life ISO 14044: various options possible. EoL: ”One fits all” formula to calculate recycling situations
Electricity Upstream: Use of national grid mixes Downstream: Use of national grid mixes
Upstream: preference to supplier-specific data Downstream: national grid mixes according to location of use.
Cut-off Usually some inputs are neglected (up to 5% of the mass)
No cut-off allowed: Fill cut-offs by worst case estimations
Capital goods
Only included in exceptional cases; e.g. wind power
Shall be included; incl. Machinery, buildings, transport vehicles
Data Quality Indicators
no systematic use/ no aggregation/ no specific requirements
Crucial element/ aggregation/ DQI targets are given
11
Use of Results: Current LCA vs. PEF Initiative
Issue Current Practice PEF Guide
Impact Assessment Categories
No default impact categories defined.
Default list of 14 impact categories which must be included (PEF Guide, p.21)
Impact Assessment Methods
Most of our clients use CML CML is only used for resource depletion. All other categories have to be modelled using other methods. (PEF guide, p.21)
Normalisation Not common practice; normalization factors outdated)
Normalisation is not required, but recommended. Normalisation will be tested in the PEF pilots and normalisation factors will be provided by the EC (end 2013)
Weighting We usually do not use weighting in our LCA studies
Weighting is mentioned as an option and is not discouraged. Will be tested in pilots and may become an issue of future PCRs (labeling)
Additional Environmental Information
If not required in an EPD we do not give additional environmental information.
Shall be included, to cover environmental information not included in default categories, or report offsets etc.

Goal and scope of the PEF test kit
13
• Giving customers access to features to fulfill special requirements of PEF. Most of the customers today have no use for these features, they do not affect their work in GaBi.
• Some features are foreseen to be discussed/changed during the course of the PEF pilot projects PEF kit for download, no integration into regular databases
• Enable use of LCIA method for land use (Soil Organic Matter, SOM) to model the foreground system of a PEF project.
• Clarify the use of the method to deal with multi-functionality in recycling situations (EoL allocation formula) provided in Annex V of the PEF guide. Enable use of the formula for modelling the foreground system of a PEF project.

Soil Organic Matter (SOM) model for the assessment of land transformation
17
• The method is described in various scientific publications, e.g. Brandao, M., Mila i Canals, L., Clift, R.: Soil organic carbon changes in the cultivation of energy crops: Implications for GHG balances and soil quality for use in LCA, biomass and bioenergy, Elsevier, 2010
from which the following graphic is taken
• Mass of carbon lost from the soil during transformation and occupation is used to describe the environmental problem field of land use
• Characteristic unit: kg C deficit eq.
• At the moment the method is not using regionalised characterisation (e.g. land use in Germany and land use in Russia count the same)
18
SOM method for assessment of land transformation
19
SOM - formula
Transformation
Occupation
• Difficult and time consuming to actually measure the carbon content of soil over time. The values of the characterisation factors are therefore calculated using various literature sources mainly from France and the UK.
• The carbon content SOCfin of sealed areas (traffic, industrial, urban etc.) is set to zero or in other words, sealed areas contain no more carbon.
• The value of SOCpot (the potential soil organic carbon content of the reference system, which is undisturbed primary forest) is very high compared to other values of the calculation. Therefore any transformation of areas that leads to a deterioration of the land quality (e.g. from arable to industrial area) has a very high impact compared to land occupation (e.g. occupation for permanent crops).
20
SOM method - limitations
• The method is rarely used in LCA case studies today
• No institution maintains the method, provides services and answers questions. Therefore the European Commission (JRC Ispra) calculated the majority of the characterisation factors of the land use flows by themselves
• There is a profound lack of data regarding production systems
• Some methodological issues are unsolved (e.g. how to deal with underground land transformation, how to deal with use changes of aquatic systems)
21
SOM method - evaluation
• The LCIA quantity “Land use, Soil Organic Matter (SOM)” can be found under Quantities - Environmental quantities - ILCD recommendations.

Method to deal with multi-functionality in recycling situations
23
• “One fits all” formula to calculate open loop/closed loop/reuse/down-cycling/energy recovery recycling situations (Annex V to PEF guide) that is mandatory.
• It follows the 50:50 approach (PE uses cut-off or avoided burden)
• GaBi datasets use cut-off approach or avoided burden approach. This formula is not used in any of the PE datasets up to now, but can be used in any model.
• The formula contains inconsistencies/mistakes/debatable items and is under debate during the pilot projects. At the moment, JRC Ispra has introduced 3 alternative formulas as test candidates. PE will and all other stakeholders are advised to actively take part in the debate via the official channels (e.g. public consultations)

Credits 50%
• Input: Production of primary material (amount: primary material plus 50% of secondary material used)
• Input: Production of secondary material (amount: 50% of secondary material used) only collection sorting, transports… are in the system boundaries
• Output: Material recycling. Secondary material substitutes primary material (where required using a value corrected substitution), credits for primary material (amount: 50% of secondary material generated)
• Output: Energy recycling. Credits for energy (electricity and thermal energy), (amount: 100% of energy generated)
• Output: The rest is landfilled, energy credits are given. The use of secondary material avoids burdens of landfilling, credits for this are given.

Multi-functionality in recycling situations - formula
• The End of Life model can be found in the plan “GLO: Multi-functionality in End-of-Life Situations (PEF guide, Annex V)” under Plans - Recycling

Multi-functionality in recycling situations – comparing existing LCA with PEF results
GWP in [kg CO2 Eqiv.]
• The formula can generate burdens and credits for landfill, even if no material is landfilled.
• No looping back of the secondary material output to saturate the secondary material input
You are affected, if… • You use secondary materials for production • You generate secondary materials or energy at the EoL • You use datasets that are currently modelled with a loop back to saturate the
secondary material
• Among the materials/products that would change are: Steel, aluminium, copper, glass, paper, plastics…
