Computer-based rating of the sustainability of legal entities. Data is stored concerning at least non-economic factors of legal entities, and is used to compute sustainability scores for each entity's performance. Financial and economic criteria may also be stored and computed. Sustainability scores may be used to rate companies, governments, products and executives on a scale, with respect to each other, or within groups such as whole industries. In one embodiment, a subscriber is permitted to customize how scores are computed, to reflect subscriber preferences.
