INTRODUCTION
Every product has an effect on the environment, which may occur at any or all stages of its
life cycle raw-material acquisition, manufacture, distribution, use, and disposal. These
effects may range from slight to significant; they may be short-term or long-term; and they
may occur at the local, regional or global level (or a combination thereof).
The interest of customers, users, developers and others in the environmental aspects and
effects of products is increasing. The information provided by this document may also be of
interest to external stakeholders who are not directly involved in the product design and
development process.
Anticipating or identifying the environmental aspects of a product throughout its life cycle may
be complex. The environmental aspects of a product must also be balanced against other
factors, such as its intended use, performance, safety and health, cost, marketability, quality,
and legal and regulatory requirements. It is important to consider its function within the
context of the system where it will be used.
The process of integrating environmental aspects into product design and development must
be continuous and flexible, promoting creativity and maximizing innovation and opportunities
for environmental improvement. As a basis for this integration, environmental issues may be
addressed in the policies and strategies of the organization involved.
Early identification and planning enable organizations to make effective decisions about
environmental aspects that they control and to understand better how their decisions may
affect environmental aspects controlled by others for example, at the raw-material
acquisition or end-of-life stages.
The widespread use of electrotechnical products has drawn increased attention to their
effects on the environment. In many countries all over the world, this has resulted in the
adoption of electrical and electronic equipment regulations affecting wastes, hazardous
substances and energy efficiency.
The purpose of this document is to help designers of electrotechnical products appropriately
to manage related environmental issues within the design process. Principles of integrating
environmental aspects into product design and development have been described in
ISO 14062. Though electrotechnical products have some specific features which have given
rise to the present document, some aspects of ISO 14062 have been taken up in this
document to make it capable of standing alone.
Subsequent sector-specific design documents may be developed to address specific sector
needs not covered in this document.

4 Strategic considerations
4.1 Goal and potential benefits
The goal of integrating environmental aspects into product design and development is the
reduction of adverse environmental impacts of the product throughout its entire life cycle. In
striving towards this goal, multiple benefits can be achieved for the organization, its
competitiveness, its customers and other stakeholders. Potential benefits may include
• lower costs by optimizing the use of materials and energy, more efficient processes,
reduced waste disposal;
• stimulation of innovation and creativity;
• increase in knowledge about the product, thus facilitating further improvements;
• reduction of risks, such as avoiding non-compliance to regulations or risks of increased
costs for end-of-life treatment due to hazardous substances.
4.2 Organizational considerations
The existing policies, strategies and structure of an organization usually take account of their
socio-economic context (for example, new regulations on wastes and on substances) and of
their stakeholders (customers, competitors, suppliers, etc.). It is important to consider this
context, because it may have economic and environmental implications for the organization
and can provide valuable guidelines for the integration of environmental aspects into product
design and development.
4.3 Product-related considerations
Integration of environmental aspects into product design and development should consider
the following product-related issues:
• early integration, i.e. address the environmental aspects early in the design and
development process;
• product life cycle, i.e. analyse from raw-material acquisition to end of life (see Figure 1);
• functionality, i.e. how well the product suits the purpose for which it is intended in terms of
usability, useful lifetime, reliability, appearance, etc.;
---------------------- Page: 8 ----------------------
SIST-V IEC Guide 114:2006
Guide 114 IEC:2005(E) – 7 –
• multi-criteria, i.e. consideration of all relevant environmental impacts and aspects;
• consideration of trade-offs in the process of seeking optimal solutions.
These issues are discussed in more detail in 4.3.2.
4.3.1 General considerations on product-related environmental aspects and impacts
This clause gives a global overview of product-related environmental aspects and impacts,
basic issues and strategic environmental objectives.
Products may have a range of environmental aspects (for example, emissions generated,
resources consumed) that result in environmental impacts (for example, air, water and soil
pollution, climate change).
The environmental impacts of a product are largely determined by the material and energy
inputs and outputs generated at all stages of its life cycle (see Figure 1). Environmental
impacts can be greatly influenced by the actions of organizations and individuals using the
product.
Inputs generally fall into two broad categories: material and energy.
• Material inputs are associated with a variety of environmental aspects; for example, use of
resources, exposure of humans and ecological systems to contaminants, emissions to air,
water and soil and the generation of waste materials and their accumulation.
• Energy inputs are required at most stages of the life cycle of a product. Energy sources
include fossil and biomass fuels, waste materials, nuclear, hydropower, geothermal, solar
and wind energy. Each type of energy source has identifiable environmental aspects.
As a rule, energy consumption of an electrotechnical product during the use stage is a very
important factor for the determination of its environmental impacts. In many cases, it is the
most important one.
Outputs generated during the life cycle of a product fall into several categories: the product
itself, intermediates, co-products, by-products and other outputs as described below.
• Air emissions comprise releases of gases, vapours and particulate matter into the air.
• Water effluent discharges comprise discharges of substances to either surface or
groundwater.
• Waste is generated during each stage of the life cycle of a product. Waste products can
become inputs to other processes, or can be treated, recycled, used as energy sources,
incinerated or land-filled.
• Other releases may include noise, electromagnetic fields, etc.
For design and development, it is useful to describe inputs and outputs in terms that are
measurable and comparable.

4.3.2 General considerations for integrating environmental aspects into product
design
The integration of environmental aspects as early as possible into the product design and
development process offers the flexibility to make changes and improvements to products. In
contrast, postponing to later stages of the process may preclude the use of desirable
environmental options, because all the major technical decisions have already been made.
A life-cycle approach is used to identify the relevant environmental aspects and impacts
during the entire product life cycle, thus helping in defining design approaches. It is important
to take into account all stages of the life cycle of a product, as shown in Figure 1, and to
recognize how products can affect the environment at different stages.
Changing any single input (for example, altering a material used) or influencing a single
output (for example, reducing specific emissions or making provisions for reducing hazardous
wastes) may affect other inputs or outputs. Therefore, it is important to ensure that any
emphasis on a single stage of the life cycle of a product does not unintentionally alter the
environmental impacts at another stage, or result in additional impacts on other elements of
the local, regional or global environment.
Considering a broad range of potential impacts and environmental criteria and exercising
caution when excluding such criteria, help ensure that the reduction of one effect does not
result in an increase in another impact.
When developing products, there is considerable value in thinking in terms of functionality
(how well the product suits the purpose for which it is intended in terms of usability, useful life
time, appearance, etc.) rather than in terms of a specific technical solution. It is, therefore,
important to adopt a broad approach when searching for new options and to highlight the
functionality required to fulfil customer or user demands and needs. Such thinking may lead to
a service solution that has reduced environmental impacts when compared with traditional
solutions only based on goods.
In addition to traditional design criteria (for example, performance, quality, cost), a variety of
environmental criteria should be taken into account. This generally involves considering a
range of different potential environmental impacts, as presented in Figure 1, through a multi-
criteria concept.
The organization may recognize that different interested parties (scientific community,
government, environmental groups, customers, etc.) may have varying perceptions of the
importance of environmental issues. These different perceptions may have relevance for
product design and development.
An integrated perspective of, and pragmatic approach to, the different life-cycle stages and
environmental aspects can help ensure that adequate solutions are found for dealing with the
trade-offs associated with most design decisions. There are three types of trade-offs:
• trade-offs between different environmental aspects; for example, optimizing a product for
weight reduction might negatively affect its recyclability. The comparison of potential
environmental impacts associated with each option can help decision-makers find the best
solution;
• trade-offs between environmental, economic and social benefits. These can be tangible
(for example, lower cost, waste reduction), intangible (for example, convenience) and
emotional (for example, image). For example, making a product more robust increases the
lifetime and, as a result, may benefit the environment by reducing long-term resource use
and waste but may also increase initial costs. This may have social as well as economic
effects;
---------------------- Page: 11 ----------------------
SIST-V IEC Guide 114:2006
– 10 – Guide 114 IEC:2005(E)
• trade-offs between environmental, technical and/or quality aspects; for example, design
decisions related to the use of a particular material might negatively affect the reliability
and durability of a product, even though this produces environmental benefits.
Experience has shown that the best solutions are specific to the product and the
characteristics of the organization. Products are complex and diverse, knowledge and
techniques evolve rapidly, and new experience improves the ability to apply novel solutions. It
is, therefore, important to find an appropriate strategy for the integration of the environmental
aspects into the product design and development process.
4.3.3 Considerations for integrating environmental aspects into electrotechnical
product design
While following the general principles presented in 4.3.2, designers of electrotechnical
equipment should take into consideration
• new legislation highlighting the importance of waste recovery and energy conservation,
and restricting the use of potentially hazardous substances;
• the preponderant role of the use stage which, for many products whose lifetime is long (10
years or more), is the main source of environmental impacts, either directly, for example,
water consumption, or indirectly, for example, energy consumption. Production of the
energy consumed is an important source of emission of pollutants to air, water or soil.
These specific features of electrotechnical products should be considered by designers as a
major source of improvements as part of a life-cycle and multi-criteria approach, so as to
avoid “improvements” made to the detriment of other environmental aspects.
Designers of electrotechnical products should consider the elements described in Clause 4
and, for this purpose, follow the approach presented in Clause 5.
5 Models for the integration of environmental aspects into the product design
and development process
The environmental compatibility of products is to be tracked throughout the product design
and development process, along with their ability to perform the technical function concerned
and their economic viability.
A major proportion of the product properties, the manufacturing costs and the environmental
effects are determined during the initial phases of the product design and development
process so it is important to consider environmental compatibility aspects during the earliest
phases. Furthermore, it is important to consider the product in the context of the system in
which it is used.
In Figure 2 and Table 1, examples of schemes are outlined for the integration of
environmental aspects into the design and development process in the electrical and
electronic industry. Different approaches may be applied within this industry; the scheme
described here should be applicable analogously if other models and other terminologies are
used.
The objectives and main points of focus of environmentally conscious design (ECD) are to be
laid down during the product strategy and product profile development phases on the basis of
a product evaluation process. The objectives and points of focus are set down in the
requirement specification.
Concepts for achieving environmental objectives are set down during the product concept
development, thereby specifying the environmental product features. The concepts and
attributes are incorporated into the performance specification.
---------------------- Page: 12 ----------------------
SIST-V IEC Guide 114:2006
Guide 114 IEC:2005(E) – 11 –
Fixed points within the product design process are to be identified for target/actual
comparison.
The concepts are put into increasingly detailed concrete form during the remaining phases of
the product design. Tools for ECD such as checklists and computer-aided methods are
employed here to support well-founded design decisions.
The product features achieved as a result of ECD are documented in the design specification.
Experience from the subsequent manufacturing, sales, product usage, maintenance and
disposal stages should be gathered and evaluated in order to continually improve the process
of environmentally compatible product design.
Figure 2 shows a possible standard model of the integration of environmental aspects into the
product design and development process, describing the correlation of activities contributing
to ECD with typical stages and documentation of this process.

An alternative as well as supplementary model for the integration of environmental aspects
into product design and development is shown in Table 1. The basic premise of this approach
is that there is a reference product of which environmental aspects are to be improved. A total
of 12 steps for product improvement are delineated, spanning from the identification of the
technical parameters of a product to the generation of the product concept, for the integration
for environmental aspects mainly occurs during the product planning and conceptual design
phases.
