Standards for Eco-Techno-Economic Analyses (eTEAs) supports the development of a uniform set of standards that are used when conducting Eco-Techno-Economic Analyses (ETEAs) on chemical and energy process systems. The standards would provide a uniform basis for comparing one process design concept to another across literature studies. This is currently almost impossible to do because each individual research study uses its own methods, assumptions, and definitions when performing analyses of proposed process concepts. However, each research study that conducted its eTEA adhering to some standard could be directly compared to another other, using established procedures, with little effort.

Latest News: September 2023 Webinar on ISO 14076 Draft Status

The working group held a public webinar to update stakeholders on the status of the draft and gather feedback. Prof. Adams covers what eTEAs are, why we need a standard, and some of the key elements and scope of the current 14076 draft. Since 14076 is a work in progress, this webinar was also used to gather feedback from stakeholders about key technical points covered under the technical specification.

ISO/WD TS 14076: Eco-Technoeconomic Analyses: Principles, requirements and guidelines

The member countries of ISO TC 207/SC 5 voted overwhelmingly to approve the development of a new technical specification. A new working group was also formed to do the work of creating the text of the standard.

As the work progresses, status updates will be provided on the ISO’s development page for the TS 14076 document.

The basic process is as follows:

Overview of the Proposed Technical Specification

The technical details and actual text of the working draft of the technical specification will be developed in the working group in the coming months, and will require many iterations. The details are expected to evolve during this process. The up-to-date version of abstract can be found on the ISO’s development page for the TS 14076 document.

The key principles of this technical specification will include:

  • Describing the basic principles, guideance, and best practices of an eco-technoeconomic analysis (eTEA)
  • Specifying the framework in which an eTEA can be conducted
  • Specifying the minimum requirements for conducting an eTEA.

The scope is general, and will apply to process systems at all scales and in all applications.

The proposed technical specification will not require or suggest particular numbers, methods, or parameters to use in an eTEA. It is intended to be general.

How the Proposed Technical Specification Fits into a Bigger Picture

The draft technical specification that has been approved and is currently in development focuses on principles, requirements, and guidance for conducting eTEAs in general.

The Project Leader (Prof. Adams) has proposed that this document should be created as a part of a larger picture, as shown below:

In this case, a second technical specification would be create that describes how to create a Parameters Document. A Parameters Document is something that describes the boundaries and parameters of the eTEA. Then, anyone could create a Parameters Document themselves that follows this standard. For example, an organization, such as a government agency, could require that eTEAs conform to a particular Parameters Document when used as part of a government grant proposal. Or, academic researchers could choose to follow a particular Parameters Document relevant to the particular technology or application of interest that was created by other researchers, academic bodies, or research societies. In this way, the ISO documents do not prescript particular methods or parameters, but they do enable the framework to make them usable in a standardized fashion.

It is important to note that this second technical specification for creating Parameters Documents have not been proposed or approved at the ISO, but the concept may inform the development of TS 14076.

Key Standardization Dates and Events

  • Ongoing 2022 – Present: ISO TC 207 / SC 5 / WG 16 technical expert members meet regularly to develop the working draft. After various cycles and decisionmaking processes, the draft Technical Specification will be sent to ballot for vote by the member countries of ICO TC 207 / SC 5. Because of the confidential nature of the process, we cannot provide regular, detailed updates to the general public during this period.

Get Involved

In order to create and adopt a universal standard, we need the involvement and input from stakeholders across the spectrum. Here is how you can get involved:

  • Join a committee or working group. People who are members of the ISO-recognized national standards organization for their home country can ask to participate in the working group by joining their country’s mirror committee to TC 207 / SC 5 and asking to be recommended as a technical expert to work on TS 14076. Contact your national committee for details.
  • Provide feedback and input. Stakeholders can provide advice, input, feedback, and other helpful input to their country’s mirror committee to TC 207 / SC 5, which can provide official comment on working drafts of the technical specification during various points in its development.
  • Encourage standards adoption. Once released, everyone can help by encouraging (and using) the standard in your workplace, your classroom, your publications, and in your own work.
