GSCM’s Sustainable Impact Score (SIS) provides agricultural businesses 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 companies firms and investors, and facilitates monitoring and reporting. It provides a measure of performance for investee firms and investors, and facilitates monitoring and reporting. SIS also allows for reporting under the Sustainable Development Goals (SDG's).
 
A detailed questionnaire is completed by the project investee management team covering all aspects of their operations., which supports the implementation of the GSCM sustainability charter. The questionnaire covers ten key areas through approximately 200 indicators.
 
The high-level issue areas are:
Sustainable management, Land rights, Local capabilities and Stakeholder Engagement, Working Conditions and Labour Rights, Energy and Greenhouse Gas Emissions, Waste, Biodiversity, Water, Soil, Economics/Ethics. 
 
The questionnaire provides the foundations for the reporting tool and is aligned with the SDG's. The SIS questionnaire results in a consolidated score for the project that captures a starting baseline for their sustainability performance.
 
GSCM established our Sustainability Impact Score “(SIS”), describing the range of goals to be addressed through investments ranging from stakeholder engagement to fair and safe working conditions to the goal of protecting and enhancing biodiversity. Importantly, the SIS has been refined to align with the Sustainable Development Goals (SDG) and provides a mechanism for quantification and tracking within what has become a more general but globally recognized reporting framework. GSCM’s sustainability framework involves four key stages:
 
The Initial Impact review can provide a basis for a plan to improve sustainability performance.
The second stage consists of a detailed questionnaire that is completed by the project investee management team covering all aspects of their operations. Including an in depth discussion with the project and the GSCM team. 
The Third stage involves goal-setting with the management team looking at a 3 to 5-year period. Goal setting is designed to create environmental and social benefits and to manage supply chain risks. At this stage alignment with and contribution towards the SDGs is assessed. Goals can be set that capture contribution to the SDGs.
The final stage establishes a quantitative SIS Model score and creates a tracking framework across a period of 10 years or more.
