In today’s hyper-connected world, data privacy is no longer just a local issue but a global challenge. That’s why a recent agreement between two major privacy regulators is drawing major attention. On April 24, 2025, the UK’s Information Commissioner’s Office (ICO) and the California Privacy Protection Agency (CPPA) signed a groundbreaking Declaration of Cooperation (DoC).
This declaration isn’t a new law, but rather a voluntary commitment to work together, share insights, and tackle common privacy challenges. Think of it as a strategic partnership between two of the world’s most influential data protection authorities.
With that in mind, this cooperation raises an important question: what will this mean for businesses and individuals, especially those operating across these key jurisdictions?
Navigating the New Landscape: The Impact of the ICO-CPPA Declaration on Organizations


While this agreement doesn’t introduce brand new laws, it profoundly impacts how organizations that operate in both the UK and California will need to approach and handle data privacy.
The DoC signals a stronger focus on consistent enforcement and a more unified approach to protecting personal data. In fact, both UK and California law already encourage this type of cross-border collaboration.
- California law instructs the CPPA to cooperate with other data protection authorities, and the UK GDPR and Data Protection Act 2018 actively promote international collaboration.
With this new declaration it helps build on that foundation, promising a more coordinated global privacy landscape with a focus on common privacy issues that ensure individuals’ rights are respected across both regions. Think about areas such as emerging technologies, particularly, children’s data, or complex international data transfers – these are critical topics that increasingly demand unified regulatory attention and will benefit from this type of collaboration as a result.
Scope of Cooperation
The DoC outlines specific areas of where the ICO and CPPA will work together:
- Joint Research & Education: The two agencies will produce shared insights and educational materials on new technologies and evolving data protection challenges. This will help foster a more cohesive understanding of privacy risks and regulatory thinking across borders.
- Sharing Best Practices: Both the ICO and CPPA will exchange experiences, policies, education, and training methods. This is crucial for developing more harmonized and effective approaches towards data protection.
- Regular Dialogue: Ongoing meetings between staff members will be facilitated, ensuring open communication and alignment.
- Mutual Assistance: While not legally binding, both agencies can mutually decide to assist and support one another as needed, with the flexibility to decline requests when necessary.
Essentially, for organizations, this agreement sets a clear precedent: expect increased regulatory alignment and more coordinated effort to effectively streamline privacy enforcement between these two significant jurisdictions.
Where Could This Type of Cooperation Lead to?
This declaration is more than just a formal handshake; it’s a powerful signal for the future landscape of international data protection.
We can likely anticipate:
- Stronger Global Partnerships: This collaboration could pave the way for similar agreements, encouraging a more connected network of international data protection authorities.
- Consistent Application of Privacy Laws: With the ultimate goal of greater regulatory alignment, this
will potentially make it easier for businesses to navigate complex cross-border compliance. - Increased Compliance Expectations: While alignment may simplify things, it may also lead to more rigorous and harmonized compliance expectations. Organizations should be prepared to meet a higher bar of expectations regarding privacy standards.
Overall, this joint approach presents a future in which major privacy authorities can proactively work together to maintain more consistent and robust data protection worldwide.

Your Next Steps for Staying Ahead of the Curve
Given this significant development, it’s time to start planning ahead. What should your organization do if it falls within the scope of both UK and California jurisdictions?
- Stay Informed: Regularly monitor updates, announcements, and guidance from both ICO and CPPA. Subscribe to their official channels and look for insights from privacy experts.
- Review Your Data Governance Framework: Assess your current privacy policies, data processing agreements, and data mapping. Identify any areas where practices in the UK and California might diverge or converge more closely in the future.
- Conduct Cross-Jurisdictional Impact Assessments: Consider how this enhanced cooperation might influence your existing or planned data activities, predominantly, those involving data flows between the UK and California.
- Engage with Industry Peers: Discuss these developments with other organizations in your industry to offer insights, knowledge-shares, and best practices.
- Consult Experts: Work with legal and privacy professionals who specialize in both UK GDPR and CCPA/CPRA to ensure you’re proactively adapting to evolving regulatory requirements.
Conclusion
The ICO-CPPA Declaration of Cooperation is a landmark agreement that underscores the global commitment to protecting personal data. While it’s a voluntary initiative, its ripple effects will undoubtedly be felt by organizations navigating the intricate landscape of international privacy laws.
By staying informed and proactive, your organization can not only meet compliance expectations but also build greater customer trust in an increasingly data-driven world.
