FOREWORD

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international

co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and

in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,

Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC Publication(s)"). Their

preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with

may participate in this preparatory work. International, governmental and non-governmental organizations liaising

with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for

Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

consensus of opinion on the relevant subjects since each technical committee has representation from all

interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence between

any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.

5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

6) All users should ensure that they have the latest edition of this publication.

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

members of its technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent

rights. IEC shall not be held responsible for identifying any or all such patent rights.

INTRODUCTION

Increasingly, there is a focus on preserving the natural environment for the good of future

generations. For this to be achieved, efficient use of energy and materials throughout the life

cycle of every product and process to conserve world's finite natural resources is essential. In

addition, release of substances and materials that might be harmful for the environment or

induce climatic changes are to be avoided or minimized. From conception to end of life of a

product, the environmental impact of all the relevant processes should be considered, including

how materials are disposed of or recovered for future use.

In order to contribute to conserving natural resources, manufacturers of low-voltage switchgear

and controlgear and their assemblies should ensure an environmentally conscious design

(ECD) involving:
• phasing-out or minimizing use of hazardous substances or materials;
• efficient use of energy and materials in the manufacture of products;

• ensuring the lowest practical energy consumption by the products while they are in use;

• at the end of product life, the possibility, as far as practical, of recycling materials for future

use, and sorting hazardous components requiring a specific treatment.

Declarations and ECD are increasingly required and in some instances mandated. These can

take several forms, for example, Type II or Type III environmental declaration, material

declaration (MD). In some business, Green Public Procurement (GPP) is applicable and/or ECD

is part of the ISO 14001 certification. Some countries and regions are also actively pushing for

environmental conservation, for example, the European Union through its Ecodesign Directive

and China through Ecodesign Initiative. Systematic demands for ECD will be required by most,

if not all customers, in the medium term.

Assessing the environmental impact of low-voltage switchgear and controlgear and their

assemblies is part of an ECD process. ECD requires the identification, measurement and

reporting of particular impacts. IEC 62430 describes the basic principles of ECD, with the goal

of reducing the potential environmental impacts of products.

Generally, the environmental impact of low-voltage switchgear and controlgear and their

assemblies is very low compared with that of the overall system into which they are incorporated

and the processes to which they contribute. The lifetime impact of processes such as the air-

conditioning of a building, the manufacture of steel or shipping far exceed that of the

manufacture and use of any associated low-voltage switchgear and controlgear.

Even though low-voltage switchgear and controlgear and their assemblies have a relatively

minor impact on the environment, there is a market need for appropriate methods for managing

these environmental matters. A simplified means of estimating the environmental impacts is

required together with readily available data to make the stakeholder's, for example

contractor's, installer's and end user's, task of assessing environmental impacts at system level

easier.

Specific rules for assessing the environmental impacts and providing appropriate data for low-

voltage switchgear and controlgear and their assemblies are among the purposes of this

document. These rules establish a common evaluation scheme of their environmental impacts

-equivalents, ozone depletion) over their
in terms of characterized impact indicators (e.g. CO

SWITCHGEAR AND CONTROLGEAR AND
THEIR ASSEMBLIES FOR LOW VOLTAGE –
Environmental aspects
1 Scope

This document, which is a Technical Specification, provides guidance to manufacturers of low-

voltage switchgear and controlgear and their assemblies in evaluating and improving the

environmental impact of their products, and in enabling effective communication using common

references for environmental information throughout the supply chain.
This document provides:

– guidance on the process and general aspects to implement environmentally-conscious

product design principles, as given in IEC 62430, essential for low-voltage switchgear and

controlgear and their assemblies;
– the Product Specific Rules (PSR) for Life Cycle Assessment (LCA);

NOTE 1 The general methods and the process to execute the LCA are in accordance with ISO 14040 and

ISO 14044 but not addressed in this document.

NOTE 2 PSR and LCA can be used for quantitative ECD and also apply for some environmental declarations,

for example Type III.

– standard environmental impact data derived from case studies and a means of using them;

NOTE 3 This is to encourage manufacturers to apply more effective quantitative methods in the ECD process

to improve the environmental efficiency of their products.

– common rules for communicating information about the presence of regulated substances

and the materials contained in the product, according to IEC 62474;

– guidance on communicating information about the end of life treatment of the product.

NOTE 4 This document is intended to replace Annex O and Annex W of IEC 60947-1:2020.
