European foreword
This document (CEN/TR 16928:2016) has been prepared by Technical Committee CEN/TC 165
“Wastewater Engineering”, the secretariat of which is held by DIN.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
1 Scope
This document applies for the implementation of environmental aspects in product standards and
system standards in the field of wastewater engineering. It provides a structure on how to identify and
consider environmental aspects and potential environmental impacts of products and systems in the
field of wastewater engineering throughout their life cycle.
NOTE Standards that are produced make environmental declarations voluntary where there are no national
regulations. This is carried out by including for “No Performance Declared”.
This Technical Report gives guidance on how this life cycle should be considered in accordance with
EN 15804.
The stages of Life Cycle Assessment (LCA) are given in Annex A.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated
references, the latest edition of the referenced document (including any amendments) applies.
EN 15804, Sustainability of construction works — Environmental product declarations — Core rules for
the product category of construction products
CEN Guide 4:2008, Guide for addressing environmental issues in product standards
3 Terms and definitions
For the purposes of this document, the terms and definitions given in CEN Guide 4:2008 and the
following apply.
3.1
life cycle
consecutive and interlinked stages of a product system, from raw material acquisition or generation of
natural resources to final disposal
Note 1 to entry: The term “product system” is defined and further explained in ISO 14040.

4 General guidance
4.1 Provisions dealing with the introduction of environmental aspects into European
Standards
European Standards concerning products and systems in the field of wastewater engineering currently
exist without any direct reference for the user to environmental awareness and the possible
environmental aspects and potential impacts. This does not necessarily lead to products and systems in
the field of wastewater engineering which are less environmentally friendly, because the user has other
incentives when considering environmental aspects, such as installation considerations, legal
requirements etc. However, the inclusion of environmental provisions encourages the consideration of
environmental aspects in cases where such incentives do not exist.
In many cases, it is sufficient to include the necessary provisions when revising European Standards
dealing with products and systems in the field of wastewater engineering by the inclusion of a new
Clause or Subclause where the relevant environmental aspects are formulated or by reference to this
Technical Report.
In standardization, environmental impacts should be considered together with other factors, such as:
a) local circumstances (see EN 752);
b) system objectives, functional requirements and performance indicators (see EN 752);
c) system design and installation;
d) product characteristics and production processes;
e) operation and maintenance;
f) total cost of ownership/life cycle costing;
g) quality;
h) legal constraints and regulatory requirements.
In order to determine how the product environmental aspects should be identified in wastewater
standards, it is necessary to understand how the product interacts with the system and the
environment during its life cycle. Environmental aspects are connected to impacts through a cause and
effect relationship.
Examples of environmental aspects to consider include:
— emissions to air;
— discharges to water and soil;
— use of raw materials;
— energy and water consumption;
— land use.
Examples of environmental impacts that can be positively or negatively influenced by provisions in
standards can include:
— climate change (through the emission of greenhouse gases);
— air pollution (through uncontrolled/untreated or accidental emissions of particulates and toxic
gases to air); and
— depletion of non-renewable resources (consumption of fossil fuels, minerals).
NOTE Additional examples are given in EN 15804.
All environmental aspects outlined in this Clause also apply to services.
As a result of this consideration, substantial energy and CO reduction and resource optimization can
be possible without compromising the fitness for purpose and longevity of the pipe systems.
4.2 Life Cycle Assessment (LCA)
Any inclusion of environmental aspects into product and system standards should consider the life
cycle of the product or system. As such, all stages of the life cycle of the relevant product or system
should be considered, including:
a) acquisition stage:
1) raw materials and energy;
2) premanufactured materials and components;
b) product stage:
1) production from raw material;
2) transport;
3) manufacturing of final products;
c) construction and installation process stage:
1) transport of the products and laying to build a system;
d) use stage:
1) collection and transportation of wastewater;
2) operation and maintenance of the system;
e) end-of-life (including recycling).
Guidance on Life Cycle Assessment (LCA) is given in e.g. EN 15804, EN 15978 and EN ISO 14044, with
special regard to recycling issues (see also Annex A). European Standards should specify requirements
for re-use.
4.3 Assessment of environmental impacts in standards
For the design of products and systems in the field of wastewater engineering, e.g. EN 752, EN 12056
(all parts), EN 12255 (all parts), EN 12566 (all parts) and the guidance given in ISO/TR 14062 should
be considered.
In accordance with CEN Guide 4, additional environmental aspects, specific for the relevant design and
product life cycle, should be identified by the applicable screening proce
