ISEAL has developed a good practice guide to help ensure that sustainability claims made by jurisdictions, landscape initiatives, and the companies that source from or support them, are credible. The guidance covers the structural and performance claims a jurisdictional entity may wish to make, along with the supporting action claims of other related stakeholders.

This report assesses leading metrics for measuring and reporting performance over time and across multiple spatial scales. It examines six critical sustainability issues: deforestation, biodiversity, water use, forced labour, poverty, and greenhouse gas emissions. The research supports sustainability systems in making data-driven outcome claims and provides insight into evaluating metric suitability. The report focuses on applicability of metrics and data sources, best practices, and associated limitations and trade-offs.
