The challenge
Carrefour faced significant fragmentation across its digital ecosystem:
- Multiple privacy regulations across more than 30 countries (GDPR, LGPD, regional frameworks).
- Heterogeneous consent systems that fragmented the user experience.
- A lack of centralized visibility into when and how consents were collected.
The solution
A group-wide implementation of OneTrust Consent & Preferences:
- More than 160 websites and 30 mobile apps.
- A unified consent banner, adapted by country and regulation.
- A centralized platform that consolidates consents and preferences for cross-border compliance.
