Bridging frameworks: How HAIP 2.0 supports interoperability with the EU AI Act

This blog article is part of a series on the Hiroshima AI Process (HAIP) Reporting Framework. The series explores different dimensions of the framework, its role in supporting trustworthy AI, and insights emerging from reports submitted by participating organisations.

This article was prepared in summer 2026 and published in September 2026 due to publication scheduling. It reflects the authors’ views and affiliations at the time of preparation.

In May 2026, the OECD launched version 2.0 of the Hiroshima AI Process (HAIP) reporting framework, on the margins of France’s G7 presidency. The voluntary reporting framework provides a global, public and comparable tool for organisations across the AI value chain to report on their actions to promote trustworthy AI. Participation enables organisations to showcase their AI governance and risk management practices, strengthen transparency, contribute to a shared understanding of how AI risks are managed, and support greater consistency across the global AI governance landscape.

HAIP differs from the EU’s AI Act, and the associated General-Purpose AI Code of Practice (CoP) in being both voluntary and public. Rather than replacing EU regulation, the HAIP 2.0 Framework can complement it. Both frameworks show significant areas of convergence and overlap. For instance, information and evidence prepared for EU AI Act compliance can serve as an information base to file a HAIP report, thereby facilitating reporting for EU companies.

This blog article explores how HAIP 2.0 and the EU instruments intersect, where they diverge, and why their complementarity matters for effective AI governance.
