The SDGs and SDG sub-goals have been translated from an investor perspective into the SDI taxonomy of product categories that are considered solutions contributing to the SDGs. The full SDI Taxonomy can be found here. When evaluating a company, the starting point is the classification of its products and services within the SDI product categories. The size of the positive contribution is calculated from the associated revenues (sales).
