A collection of background materials explaining the basics about blockchain technology.

This briefing note captures broader insights from a project ISEAL implemented with support from the German International Development Agency GIZ in 2018-2019, in which we explored the implications and linkages between corporate due diligence processes and voluntary sustainability standards.

This guidance developed by ISEAL on Chain of Custody (CoC) System is a reference document for sustainability standards systems that complements ISEAL's Sustainability Claims Good Practice Guide.

This document complements the revised ISEAL Chain of Custody Models and Definitions guidance v2.The following diagrams provide worked examples of how certified materials move through different supply chains, illustrating segregation, controlled blending, and mass balance approaches. They are strictly illustrative – real supply chains are complex, context-specific, and may vary depending on local practices, ownership structures, and processing steps.These examples focus on the main product flow; by-products or waste from production account for the remainder of the material.

In 2016, nine ISEAL members came together to form the Integrated Pest Management (IPM) Coalition. The coalition aims to reduce and eventually eliminate the use of highly hazardous pesticides, and to promote more sustainable alternatives. It also aims to harmonise approaches to pesticides between ISEAL member standards.

This 2016 guidance developed by ISEAL on Chain of Custody (CoC) Models and Definitions is a reference document for sustainability standards systems that complements ISEAL's Sustainability Claims Good Practice Guide.

This guidance document offers suggestions as input for consideration for the recent EUDR guidelines on the use of certification. ISEAL has built a broad-based consensus around what constitutes credible operating practices for sustainability certification schemes. Our Code of Good Practice captures this consensus in a publicly available normative document against which all ISEAL Code compliant members have been evaluated.

The ISEAL Innovations Fund supports sustainability systems to drive collective action on key sustainability challenges. 

This case study is part of a series that looks at how credible VSS are responding to one of the most important legislative developments: the EU Deforestation Regulation (EUDR), which aims to prevent products associated with deforestation from being sold on the EU market. Featuring Rainforest Alliance and Fairtrade International, it explores how credible VSS drive not only compliance but also meaningful transformation across the cocoa sector.

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.

We are excited to launch the revision of the ISEAL Chain of Custody (CoC) Definitions and Models Guidance. The revision process will include:

This is a standardised metadata set that provides a common code for search and discovery to improve the flow of sustainability information.

This resource explores the concept of adopting a holistic and interconnected framework for managing and utilising data. It highlights how a digital ecosystem approach facilitates collaboration and data sharing across various stakeholders and systems to address complex challenges like ensuring sustainability through origin traceability. 

This technical paper identifies opportunities for further Guidance that we believe will strengthen an effective implementation of EUDR. ISEAL has been engaging closely with sustainability systems to understand how they are aligning and adapting in response to EUDR. In the process of adapting, sustainability systems have identified outstanding ambiguities in the Regulation and published FAQs (v1.2) which may hinder effective and consistent implementation of EUDR by operators and traders. Our paper identifies three opportunities for further guidance:

Chain of custody (CoC) and traceability are big news right now. But are we all speaking the same language? We’re updating our CoC models and definitions guidance and we would value your input. Our public consultation is now open.
