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 first examines how standards systems are being applied to landscapes and jurisdictions. It then explores factors that are important to the effective application of sustainability strategies at a landscape level and identifies opportunities to strengthen the role that standards systems can play in implementing those strategies.
