NatWest migrates its ESG data platform to Snowflake

Snowflake's current NatWest customer evidence states that NatWest's ESG team migrated its data platform to Snowflake, established an all-cloud ESG data source of truth and decommissioned legacy on-premises systems. Snowflake's dated 6 March 2026 event evidence independently establishes active NatWest use of Snowflake by that evidence horizon.

Organisation
NatWest Group, United Kingdom
Predecessor
NatWest's existing on-premises systems, which were not equipped for the ESG team's requirements or the large, varied data sets that ESG reporting demanded
Destination
An all-cloud ESG data source of truth on Snowflake with the legacy on-premises ESG systems decommissioned
Workload
Snowflake
Stage
operational
Evidence boundary: The dated 6 March 2026 Snowflake evidence proves active operational use by that date; it is not asserted as NatWest's private migration cutover day. The claim is bounded to the ESG data-platform migration documented by Snowflake and does not extend to every NatWest data workload.
