Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).

Introduction
ISO 20140 specifies a method for evaluating the energy efficiency and other factors of a manufacturing
system that influence the environment, e.g. energy consumption, waste and release.
ISO 20140 is applicable to manufacturing systems for discrete, batch, and continuous manufacturing.
ISO 20140 focuses on manufacturing systems that have a hierarchical structure.
ISO 20140 can be used for:
— benchmarking of environmental performance against a generic reference manufacturing system or
comparing between different manufacturing systems;
— alternative studies for improving environmental performance;
— setting targets of environmental performance improvement;
— visualizing the environmental performance of a manufacturing system under operation.
Expected users of ISO 20140 are:
a) managers who are responsible for environmental conditions of a manufacturing system;
b) engineers who design manufacturing processes for products;
c) engineers who design a manufacturing system;
d) engineers and foremen who are responsible for manufacturing products.
This document specifies a process for environmental performance evaluation of activities executed by
a manufacturing system based on the general principles described in ISO 20140-1. The process uses
environmental performance evaluation data based on ISO 20140-5.
This document does not specify any evaluation process specific to particular implementations of
manufacturing systems.

Part 2:
Environmental performance evaluation process
1 Scope
This document specifies a process for environmental performance evaluation of activities executed by
a manufacturing system based on the general principles described in ISO 20140-1. The process uses
environmental performance evaluation data based on ISO 20140-5.
This document does not specify any evaluation process specific to particular implementations of
manufacturing systems.

numerical representation of environmental influence (3.3) caused by a manufacturing process in a given
type of environmental influence and in a given mode
3.2
energy efficiency
ratio or other quantitative relationship between an output of performance, service, goods or energy,
and an input of energy

3.3
environmental influence
result of manufacturing process that can cause environmental impacts and that is considered
throughout the life cycle of the manufacturing system associated with the process
Note 1 to entry: Environmental influence, such as energy consumed and CO emitted, can cause environmental
impacts, such as global warming and sea level rise.
EXAMPLE Amount of electric energy consumed; amount of CO emitted; amount of hazardous substance
discharged.

4 Framework of environmental performance evaluation process
The environmental performance evaluation process shall comprise the sub-processes of developing a
specification of environmental performance evaluation, specifying the environmental KPIs, calculating
the environmental KPIs, and reporting the evaluation results as illustrated in Figure 1. This document
specifies the requirements for these sub-processes.
a) Developing specification of environmental performance evaluation
A specification of environmental performance evaluation is developed in this process. This
specification includes requirements for aggregated EPE data.
b) Specifying environmental KPIs
Environmental KPIs are specified by a formula with the necessary conditions, according to the
specification of environmental performance evaluation specified by the process described in a) above.

c) Calculating the environmental KPIs
Values of each environmental KPI are calculated according to the environmental KPI specification
specified by the process described in b) above.
An aggregated EPE data, which represents the environmental influence, is provided by the
aggregation process for each KPI.
A system value is obtained for each KPI according to the specification of environmental performance
evaluation specified by the process described in a) above.
NOTE The actual capture and calculation of system value for use in calculating each KPI is outside the
scope of ISO 20140.
d) Reporting
The results of the environmental performance evaluation, such as environmental KPI specification
and its calculated values, are reported with
