of publication. Currently, the present document considers DSLAM DSL, MSAN, PON OLT and Point to Point OLT
equipment. Other access technologies may be included in further versions of the present document.
The present document also considers measurement methodology for VDSL2 equipment with vectoring functionality.

The present document focuses on Network Equipment. The end-user equipment is handled in other documents, see
ETSI EN 301 575 [i.6] for CPE [i.6] and ETSI EN 303 423 [i.9] for network standby.

The present document aims to provide a methodology for evaluating the environmental impact of ICTs objectively and
transparently and is based upon the Life Cycle Assessment (LCA) methodology standardized in ISO 14040 [1] and
ISO 14044 [2].
The present document can be read by anyone aiming for a better understanding of the specific conditions and
requirements applicable to the LCA of ICT goods, networks and services. However, the present document is especially
intended for LCA practitioners with a prior knowledge of LCA standards, i.e. ISO 14040 [1] and ISO 14044 [2].
The purpose of the present document is to:
• provide ICT-specific requirements, in addition to those of ISO 14040 [1] and ISO 14044 [2], to ensure a
sufficient quality of LCA studies of ICT goods, networks and services; increase the quality of the LCA by
adding ICT specific requirements to those of ISO 14040 [1] and ISO 14044 [2];
• harmonize the LCAs of ICT goods, Networks and Services;
• increase the credibility of LCAs of ICT goods, networks and services;
• increase the transparency and facilitate the interpretation of LCA studies of ICT goods, networks and services;
• facilitate the communication of LCA studies of ICT goods, networks and services; and
• provide a methodology for telecommunication operators and service providers to assess the environmental
load of one or more Services carried by their ICT Networks.
While recognizing ISO 14040 [1] and ISO 14044 [2], including Annex A of ISO 14040 [1] "Application of LCA", as
normative references, the present document will give generic and specific requirements for the LCA of ICT goods,
networks and services. The present document is valid for all types of ICT goods including end-user goods and also for
ICT networks and services. The present document also gives guidance to the assessment of software. LCA practitioners
are encouraged to also consider other environmental aspects in accordance with ISO 14040 [1] and ISO 14044 [2].
The present document defines a set of requirements which reflect the quality that LCA practitioners should strive for. At
this stage some of the requirements put forward here are considered as challenging due to LCA tool limitations, a lack
of data, limitations in data granularity, etc. It is thus recognized that compliance to all requirements in the present
document may not be possible at the time the present document is published. However, to foster results of LCAs
becoming more transparent and, for the quality of data and LCA tools to improve over time, the present document
defines the requirements outlined in the following pages. The present document requires that deviation(s) from the
requirements are clearly motivated and reported. For further details regarding compliance refer to clause 5.2.
Comparisons of results from environmental assessments of ICT goods, networks and services, assessments which have
been performed by different organizations are beyond the scope of the present document, as such comparisons would
require that the assumptions and context of each study are exactly equivalent.

The present document specifies the method and metrics to determine the energy efficiency of operational Network
Function Virtualisation (NFV) applications and their associated infrastructure when that infrastructure is implemented
outside the boundaries of the access fixed, cable and mobile networks which they serve.
The present document:
• Extends the Objective KPIs of ETSI EN 305 200-2-2 [i.2] (fixed access networks) and ETSI
EN 305 200-2-3 [i.3] (mobile access networks) to assess the impact of NFV when applied to those networks as
described in ETSI GR NFV 001 [i.4].
• Does not consider any assessment of energy saved by the implementation of NFV as there can be no timestamped
comparison of an operational infrastructure from which functions have been removed to a virtualized
environment.
NOTE: In an ICT network (e.g. a fixed access network) comprising many Network Distribution Nodes (NDNs)
with different loading levels it is not clear that there will always be an energy consumption benefit - the
more relevant benefit being network and operational flexibility (such as reduced maintenance or increased
reliability).
The present document:
• Does not address the operational energy efficiency of specific Information Technology Equipment (ITE) such
as servers which may provide NFV facilities. Other ETSI EN documents (e.g. ETSI EN 303 470 [i.1]) have
been prepared to address such factors.
• Does not specify any assessment of the overall effectiveness of an NFV implementation although it contains
information in an informative annex regarding the technical milestones that would be required for this to be
addressed in a future revision of the present document.
The KPIs specified are primarily intended for trend analysis - not to enable comparison between individual
implementations of NFV unless the conditions of operation are "similar".
