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

Introduction
A distinctive feature of the sharing economy as a new economic model is its reliance on a triangular set of
interactions among providers and users, facilitated by platform operators.
Figure 1 — Figure representing sharing economy
The sharing economy potentially provides new opportunities and innovations for the production and
distribution of different types of products and assets. As such, if the sharing economy model is properly
structured and implemented, it can generate wealth, provide needed products and assets and align with
the economic, social and environmental objectives articulated in the United Nations (UN) Sustainable
Development Goals (SDGs). At the same time, it is important to recognize that, if applications of the sharing
economy are not developed and implemented properly, they can have potential adverse effects on workers,
consumers, citizens, businesses, the environment and other interests.
This document specifies requirements for and gives guidance on the operationalization of this new economic
model. This document is intended to assist in realizing the positive potential of the sharing economy while
minimizing its adverse effects in diverse applications of the unique sharing economy triangular model.
This document addresses key economic, social, and environmental considerations and factors associated
with planning, developing, governance, management, delivery, monitoring, evaluating, and continually
improving sharing economy applications and approaches in a manner that is optimally aligned with
the UN SDGs. This is particularly important for key actors and stakeholders within the sharing economy
ecosystem (i.e. the infrastructure and services associated with the network of organizations, other actors
and stakeholders involved in the sharing economy).
Via a structured implementation framework, government, platform operators, providers, users and other
actors and stakeholders will also be able to better relate to and understand the connection, interaction,
impact and benefit of evolving digital technologies such as artificial intelligence, blockchain, cybersecurity,
metaverse, web3.0, fintech, etc. that potentially impact on their existing sharing economy applications, and
thus plan for necessary interventions and actions.
This document complements ISO 42500, ISO 42501 and ISO/TS 42502.

4 Relationships between platform operator, provider, user and other actors in the
implementation framework
As depicted in ISO 42500, the basic sharing economy model generally involves a triangular relationship
between platform operators, providers and users, and the interactions between these parties.
These interactions are intermediated via a platform which typically involves five distinct transaction phases
(see Figure 2): on-boarding, information delivery/update, connection, transaction and rating/review.

As described in ISO 42501 and ISO/TS 42502, platform operators provide necessary mechanisms and
resources to ensure that transactions between provider and user are facilitated in a transparent,
trustworthy, accountable and inclusive manner.
In accordance with ISO/TS 42502 regarding matters related to verification of their identity, capability and
capacity as well as legality of their products and/or assets, the provider shall conform to requirements set
by the platform operators.
The individual and/or organization that is the recipient of the products and/or assets shall interact and
transact with the provider via the platform in a manner that is consistent with the general principles of the
sharing economy as described in ISO 42500.
In a typical scenario, the user will communicate and exchange information on their requirements for a
product and/or assets via the platform. The platform operator will then provide necessary mechanisms to
communicate and ensure that the information is passed on an
