Introduction
During the process of researching, designing, developing, and commercializing process systems, many
decisions need tomust 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
(such ase.g. product yield, process efficiency, and quality), economic indicators (such ase.g. cost, profitability,
and returns on investment) and environmental indicators (such ase.g. greenhouse gas (GHG) emissions,
resource depletion, or freshwater consumption). These ultimately affect the total value of the process system
to companies, clients, consumers, government, and society.
An environmental techno-economic assessment is a method for characterizing(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 need tomust be made as a part of an environmental techno-economic
assessment whicheTEA 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 variability in methods for environmental techno-economic assessmentseTEAs, there is a need for
practical guidance on their performance. Organizations can benefit significantly by providing clear and
consistent guidance on how to conduct an environmental techno-economic assessmenteTEA.
Therefore, the objectives of this technical specification are todocument:
— Establishestablishes terminology and key definitions of common metrics used in environmental techno-
economic assessmentseTEAs;
— Provide guidance and provides requirements and guidance on how to conduct environmental techno-
economic assessmentseTEAs;
— Provideprovides a framework for clearly documenting the results and the underlying assumptions used
in an environmental techno-economic assessmenteTEA so that others can effectively interpret the results.
This document is intended for eTEA practitioners. eTEA practitioners are(i.e. people who conduct eTEAs, such
as data gathering, making calculations, or assessing and interpreting the results. ). Practitioners can include
industry, government, or academia.
An illustrative example of an eTEA is given in Annex A.
