GSCM’s Sustainable Impact Score (SIS) provides agricultural businesses and investments with a metric comparable to an earnings per share (EPS). The SIS allows for the transparent measurement of impact in a way that is consistent across projects. It provides a measure of performance for projects and investors, and facilitates monitoring and reporting. SIS also allows for reporting under the Sustainable Development Goals (SDG's).

The Initial project review contains a high-level checklist, analysis of risks and opportunities and evaluation of sustainability governance. Critically, the project/company company does not need to be operating under a full sustainability regime at the beginning; the Initial Impact review can provide a basis for a plan to improve sustainability performance.
