2 Development <strong>and</strong> Application of the Criteria <strong>for</strong><br />
Evaluation<br />
The development of criteria <strong>and</strong> a procedure <strong>for</strong> the evaluation of characterisation <strong>models</strong><br />
addressing midpoint <strong>and</strong> endpoint levels (Areas of Protection, AoP) is described in this<br />
section. The criteria <strong>and</strong> procedure serve to analyse existing characterisation <strong>models</strong> <strong>and</strong><br />
factors across the most common impact categories, at both midpoint <strong>and</strong> endpoint levels.<br />
The aim of this analysis is to identify the best practice among existing characterisation<br />
<strong>models</strong> <strong>for</strong> each impact category.<br />
The development of criteria builds on the work of the SETAC working groups (Udo de<br />
Haes et al., 2002) <strong>and</strong> the Life Cycle Impact Assessment programme of the UNEP-SETAC<br />
Life Cycle Initiative on the <strong>LCIA</strong> selection criteria <strong>and</strong> their application to the acidification<br />
impact category (Margni et al., 2008). This work has been modified <strong>and</strong> extended. While it<br />
integrates criteria regarding policy relevance <strong>and</strong> applicability to LCI data sets, it also covers<br />
all emission-related midpoint categories, resources <strong>and</strong> l<strong>and</strong> use, <strong>and</strong> the damage<br />
characterisation <strong>models</strong> <strong>for</strong> all Areas of Protection <strong>for</strong> damage assessment.<br />
Consultation process <strong>for</strong> development of criteria<br />
The development of criteria <strong>and</strong> their application in evaluating the methods from the<br />
different impact categories has been aided by a consultation process involving domain<br />
experts, the international cooperation of partners on good practice on LCA, including:<br />
National LCA project in Brazil, China, Japan, Malaysia, <strong>and</strong> Thail<strong>and</strong>,<br />
European Commission <strong>and</strong> EU Member-States representatives,<br />
UNEP,<br />
European Plat<strong>for</strong>m on LCA Advisory Groups, including Industry Associations <strong>and</strong> LCA<br />
research/consultancy organisations, <strong>and</strong><br />
a public stakeholder consultation.<br />
2.1 Criteria <strong>for</strong> the evaluation of characterisation<br />
<strong>models</strong><br />
The analysis of the different characterisation <strong>models</strong> relies on a set of general criteria<br />
based on fundamental <strong>requirements</strong> <strong>for</strong> <strong>LCIA</strong> methods (both characterisation <strong>models</strong> <strong>and</strong><br />
factors), which are the same <strong>for</strong> all impact categories. These consist of 5 scientific criteria<br />
<strong>and</strong> 1 stakeholder acceptance criterion.<br />
Scientific criteria:<br />
Completeness of scope<br />
Environmental relevance<br />
Scientific robustness <strong>and</strong> certainty<br />
Documentation, transparency <strong>and</strong> reproducibility<br />
