True Sustainability Index™
The True Sustainability Index™ (TSI) is the world’s first context-based triple bottom line model for measuring, rating, ranking and reporting the true sustainability performance of organizations. It is context-based in the sense that it expresses organizational performance in terms of impacts relative to actual social and environmental conditions in the world, and not just in terms of top line trends, efficiency or incremental effects.
Of additional significance to the TSI is the extent to which it meets the Global Reporting Initiative’s call for ‘sustainability context’ in corporate sustainability measurement and reporting, as follows (from GRI, G3):
Performance information should be placed in context.
The underlying question of sustainability reporting is how an organization contributes to the improvement or deterioration of economic, environmental, and social conditions at the local, regional, or global level.
Simply reporting on trends in individual performance (or the efficiency of the organization) will fail to respond to this underlying question.
Reporting organizations should therefore seek ways to express their individual performance in relation to broader environmental and social sustainability.
The TSI is unique in this regard. It is also unique in that it is comprised of only 15 metrics, as opposed to up to 150 metrics found in other measurement models (e.g., GRI). Click here for more information about the True Sustainability Index™.
