Introduction
In 2013, the European Commission (EC) released a proposal for the use of common methods to measure and
communicate the life cycle environmental performance of products and organizations [i.1]. EC started a journey to test
the Product and Organization Environmental Footprint methods in action. Together with more than 260 volunteering
organizations EC tested how to develop product- and sector-specific rules, how to communicate and verify
Environmental Footprint (EF) information. In January 2018 EC announced that the journey is coming to an end [i.2].
It can therefore be concluded that Life Cycle Assessment (LCA) seems to be slowly converging into a useful policy
tool. To this end the electronics and ICT industry and others have in recent years started to prepare for possible LCA
legislation from the European Commission according to the so called Product Environmental Footprint (PEF) method.
The aim of PEF is to enhance the quality of LCAs by harmonization, leading to comparable product environmental
footprints within specified product groups in a single market.
Figure 1 shows a set of non-comparable and non-standardized GWP100 results for smartphones for selected life cycle
stages.

Figure 1: Non-comparable and non-standardized GWP100 results for smartphones
The PEF method might help verify the reliability of the results such as those shown in Figure 1.
Nevertheless, PEF has been questioned for not leading to comparative results but only reproducible results [i.3] and
[i.25]. Using PEF, specific features of individual products can seemingly not be reflected (e.g. how to compare
"standard" and "durable" devices when the same lifetime is assumed). Still, the PEF Category Rules (PEFCR) Guidance
[i.7] states that comparability is possible if the results are based on the same PEFCR.
NOTE: This might be true for PEFCR but it is not true for the EPD System Product Category Rules (PCR) [i.19]
which are too flexible regarding data quality and functional unit selection.
Examples of unique features of PEF - compared to e.g. the European Telecommunications Standards Institute (ETSI)
standard for LCA [i.4] and [i.5] - are the strict requirements on data quality, definition of exact FU, default end-of-life
(EoL) scenario, mid-point impact categories, and that cut-off should be avoided. Moreover - in order to be compliant
with PEF - the industry leaders for each product group sold in the EU - such as smartphones - will have to reach
consensus on the product category rules (PCR) for these product groups.
Recently IT storage equipment - belonging to classification 26.2 in Statistical Classification of Products by Activity in
the European Economic Community [i.6] - was investigated in an official PEF pilot.
In 2017 a guidance document was published including the experience of the PEF pilots [i.7]. Oja et al. argued that it is
important to find a balance between comparability, reliability, and costs when performing PEF LCAs [i.8].
The common wisdom is that simplified LCA approaches do not have enough precision compared to Full LCA (FLCA)
when applied to the rather complex life cycle of smartphones. Still, there exist several simplified LCA methods for
smartphones [i.10]. Andrae identified that there are at least 14 different - simplified and full - methods for LCA of
consumer electronics such as smartphones [i.11]. One of the FLCA methods is the PEF method, expected to be the
state-of-the-art for FLCA [i.7]. In the present document only FLCA of smartphones will be discussed. PEF has very
strict data quality requirements as product comparisons need good quality data. Ojala et al. [i.8] argued that PEFCR
developers should devote time to finding the most appropriate methodological choices. There exists no analyses of the
degree to which current smartphone Full LCAs fulfil the requirements of the strict PEF Guidance [i.10]. To shed light
on that issue is one of the main objectives of the present document.
Moreover, the present document will discuss the discrepancy between FUs currently formulated for smartphones
compared with those required by PEF. While comparability is the ultimate aim of the PEF FLCA method, it will require
very high data quality lowering the uncertainty. Even with "perfect" data quality, there will be variability of LCA scores
for the same type of smartphones.
Andrae and Vaija [i.5] argued that PEF has several strengths and weaknesses. Strengths include guidance and
requirements on FU definition. Moreover, PEF demands relatively precise analyses of the supply chains which could
lead to eco-innovation. Furthermore, the fact that cut-off is not "allowed" gives an estimation of the truncation error.
Another benefit is that the circular footprint formulae should improve the end-of-life modelling for all.

However, again, the PEF method has several weaknesses. First the ambitious data collection targets cannot - by most
actors - be applied consistently along the supply chain. Furthermore, the usefulness beyond traditional ISO [i.12] and
[i.13] and ETSI FLCA standards [i.14] is in doubt as these data and comparability issues are not solved.
PEF also might threaten the flexibility needed by LCA practitioners in their pursuit to influence the product design
holistically. Such worries are echoed by recent research [i.25].
The present document is expected to provide valuable input for all users of LCA within the smartphone sphere and to
some degree also for the consumer electronics sphere. Five smartphone manufacturers approaches for FLCA have been
analysed based on openly available information.

1 Scope
The present document investigates current approaches, concepts and metrics of LCA as proposed by PEF and their
applicability for the smartphones. The present document:
1) searches to identify if Product Category Rules (PCR) and Life Cycle Assessment (LCA) models for the
smartphone product category have been developed;
2) explores existing PCRs and LCAs for gaps compared to the PEFCR Guidance requirements;
3) explorse the challenges associated with: setting the scope, defining the unit of analysis, reference flow,
representative products, product classification, system boundaries, data quality requirements, data collection,
benchmark and classes of environmental performance, interpretation, reporting, disclosure, communication,
and verification;
4) explores the challenges with PEF Screening (impact assessment, interpretation and conclusion, report).
