Overview - ISO/TR 24217-2:2021 (Fine bubble technology & SDGs)

ISO/TR 24217-2:2021 is a technical report that provides guidelines for linking fine bubble technology applications to the United Nations Sustainable Development Goals (SDGs). It helps suppliers, document writers and stakeholders identify where fine bubble systems (compact, air–water based solutions) can contribute to specific SDG targets and how to present that contribution clearly to users, investors and regulators.

Key topics and technical focus

• Scope and purpose - Guidance for suppliers to show which parts of the SDGs their fine bubble technologies can support, and for writers to assess SDG contributions of related documents.
• Actors and stakeholders - Identification of partners and stakeholder groups (suppliers, users, communities, vulnerable groups) that can be affected by or benefit from fine bubble applications.
• Identifying SDG elements - Methods to select key SDG elements relevant to fine bubble technologies using sources such as safety data sheets, risk studies, sustainability reports and stakeholder input.
• Assignment of SDGs - Procedures to map specific applications of fine bubble technologies to relevant SDGs (see Annex A examples).
• Technical principles & measurement - References general measurement principles and categorization of fine bubbles (normative references to ISO 20480‑1 and ISO 20480‑2) to support objective claims.
• Review and revision - Guidance on documenting, reviewing and updating claims and evidence linking applications to SDGs.
• Evidence and evaluation - Informative annexes (B and C) provide example evaluation parameters and comparison data to substantiate SDG contribution claims.

Practical applications and who uses this standard

• Manufacturers and suppliers - To demonstrate how products (water treatment modules, cleaning systems, agricultural/aquaculture enhancers) align with SDGs for marketing, procurement and investment cases.
• Standards writers and technical authors - To assess and document SDG relevance of technical documents and product literature.
• Investors and banks - To evaluate SDG-linked investment opportunities and to verify sustainability claims.
• Policy makers, consultants and end users - To understand environmental, social and economic benefits (e.g., clean water, energy efficiency, sustainable food production) that fine bubble technologies can deliver.

Related standards

• ISO 20480‑1 - Terminology for fine bubble technology.
• ISO 20480‑2 - Categorization of fine bubble attributes.

ISO/TR 24217-2:2021 is a practical resource for anyone needing to link fine bubble technology to SDG reporting, sustainable procurement and investment evaluation while relying on recognized measurement and documentation practices.

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

Introduction
In 2015, the United Nations set an ambitious 15-year plan to address some of the most pressing issues
for the world. The Sustainable Development Goals (SDGs), known as Global Goals, are a global address
to action to eradicate poverty, protect the planet and ensure that all the world people enjoy peace and
prosperity. These 17 goals build on the successes of the Millennium Development Goals with additional
areas such as climate change, economic inequality, innovation, sustainable consumption, peace and
justice, among other priorities. The goals are interconnected – often the key to the success in individual
initiatives for issues which are associated more commonly with each other. As SDGs get spread, there
appears a trend that SDGs’ investments are brought about, just as environment, social and governance
(ESG) bonds are creating ESG investments. It is predicted that the world investors would evaluate and
judge whether they are promoting SDGs and would become targets for investments or not. For example,
in March 2017, the World Bank issued sustainable development target-linked credits for the first time.
These credits are to fund for projects that meet the goals of the SDGs, such as eradicating poverty,
reducing environmental impacts, correcting gender disparities, and improving public health. Capturing
this trend is key.
Since the SDGs can be applied in various fields, they are also applicable to fine bubble technology,
which has the following two main features. First, fine bubble technology has a feature that involves
simple components such as water and air. Further, most of fine bubble generating systems are compact
and movable. Second, it is applicable and effective in many fields such as water purification, cleaning,
agriculture applications, fishery applications and environmental recovery. Due to these two features,
it can be applied relatively easily to water purification and cleaning in developing countries. Moreover,
since fine bubble technology has eco-friendly cleaning and food production technologies, it can be said
that it is effective as a common technology worldwide.
Although it is considered possible to link fine bubble technology with such features to the SDGs, the
association between fine bubble technology and the SDGs is currently insufficient. For this reason,
guidelines are necessary, which link SDGs and fine bubble technology.
This document provides a path for fine bubble suppliers to contribute to SDGs. Furthermore, showing
banks and investors what successfully contributes to the SDGs can help them to leverage sufficient
investments and to avoid improper investments.

4 Actors contributing to the SDGs through fine bubble technologies
4.1 Partners
When partners consider a certain element of the SDGs within the given system, related systems and
subsystems can also be considered, because they are all interconnected and interdependent.
For example, an aspect that seems to be primarily related to the environmental dimension of
sustainability is also thought to have an impact within a social or economic dimension of sustainability,
e.g. water purification using fine bubble technologies has an environmental impact, as well as a social and
an economic impact on people and communities working for the factory. The potential for these multiple
impacts to occur is always considered when drafting provisions relating to any element of the SDGs.
4.2 Stakeholders
Stakeholders consider how application of a standard would have an impact on their approach, in light
of the SDGs. Like other types of impact, the impact on stakeholders can be either beneficial or adverse.
Different groups of stakeholders can be affected by issues of SDGs, either individually or collectively,
and any group that can potentially be affected by the use or application of a standard can be taken
into account by standards developers. In addition to consumers, customers, workers, organizations in
the supply chain and communities, this also includes future generations and the wider general public,
especially when coping with broader issues of the SDGs, such as climate change.
Particular attention can be paid to potentially vulnerable stakeholders, such as children or persons
with special needs, because the impact on them is thought to be both greater and more difficult to
identify than that on other stakeholder interests.
5 Identifying a key element of the SDGs specifically applicable to fine bubble
technologies
Regarding the approaches outlined in Clause 4, suppliers can identify the key elements of SDGs that
are considered relevant and critical to the subject area. Many sources of information on SDGs can be
useful in this process. These sources include material data sheets, studies on risks or trends, legal
requirements, product declarations, sustainability reports, impact assessment reports, published peer-
reviewed scientific studies and the results of stakeholder consultations.
Table 1 shows examples of key elements of SDGs specifically applicable to fine bubble technologies.
