Environmental management — Environmental techno-economic assessment — Principles, requirements and guidance
This document provides principles, requirements and guidance for performing an environmental techno-economic assessment (eTEA). eTEAs provide economic analyses combined with an assessment of environmental impacts. This document specifies requirements for documenting the results, underlying assumptions, parameters and methodologies used in an eTEA. This document is applicable to process systems of any size or production scale.

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 document 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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at

Introduction
During the process of researching, designing, developing and commercializing process systems, many
decisions must be made concerning details such as the selection of unit operations, equipment types and
sizes, operating conditions and procedures, mass and energy flows, financing contracts, sales prices and
environmental releases. These decisions are made based on many indicators, especially technical indicators
(e.g. product yield, process efficiency, quality), economic indicators (e.g. cost, profitability, returns on
investment) and environmental indicators (e.g. greenhouse gas (GHG) emissions, resource depletion,
freshwater consumption). These ultimately affect the total value of the process system to companies, clients,
consumers, government and society.
An environmental techno-economic assessment (eTEA) characterizes process systems in terms of key
environmental, technical (“techno”) and economic factors. These characteristics are represented by a
collection of commonly understood metrics that can then be interpreted for decision-making purposes. Many
assumptions must be made as a part of an eTEA can have a major impact on the results, with financial and
environmental consequences throughout the life cycle of the process and its products. These assumptions
can include the values of key parameters, analysis boundaries and the methods themselves. Because of its
importance and the wide variabili
