This report documents ideas for how certifiers can leverage blockchain technology to reduce audit inefficiency, create a single source of truth for chain of custody (CoC) tracking and support sustainability data reporting. 
ISEAL has revised its Chain of Custody (CoC) Models and Definitions Guidance to improve clarity and consistency for stakeholders across sectors, reflecting major shifts in supply chain management. The updated guidance is intended to address new regulatory demands (e.g., EUDR, CSRD), technological advancements like blockchain, and the inclusion of additional CoC models such as Controlled Blending and Controlled Mass Balance.
This case study highlights how credible voluntary sustainability standards (VSS) support palm oil companies with regulatory requirements such as the EU Deforestation Regulation (EUDR). Featuring the Roundtable on Sustainable Palm Oil (RSPO), it explores how VSS enable traceability, ensure legal production, and promote smallholder inclusion - helping businesses build deforestation-and conversion-free (DCF) supply chains that go beyond compliance.
With a shift towards outcome-focused sustainability standards and measurement, ISEAL commissioned 3Keel to review different metrics for monitoring sustainability performance.
