What SUSTEquity is The SUSTEquity Model is an original analytical tool that significantly differs from most other sustainability-related tools by adopting a demand-side (rather than a supply-side) perspective. Our model essentially responds to a question that is crucial for any company with sustainability commitments: How are sustainability initiatives and communications actually perceived by our customers? By answering this question, our model provides companies with key insights, which can assist CEOs and middle-managers in efficiently and responsibly allocating monetary, time, and human resources among sustainability initiatives that not only contribute to environmental protection and/or societal well-being but also expand business success. The critical strength of our model lies in its nature. The SUSTEquity Model is a science-based tool that: 1) Collects data directly from customers using techniques that are established in the global academic community; 2) Analyzes such data using rigorous statistical methods and algorithms to obtain solid and significant results; 3) Converts such statistical results into strategic insights that allow companies to identify what sustainable actions (current or planned) can generate the greatest value in the eyes of their customers.
