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.

Polygon data can provide huge benefits to sustainability systems if collected and used effectively. Recognising this, we have produced a package of tools and guidance on the benefits of polygon data and how to collect it.
