1. A computer system for calculating a total sustainability indicator for a classification for a product including one or more components, the system comprising: a customization module configured to allow a user to: define a plurality of regulatory categories, select at least one regulatory list to be a member of each regulatory category, assign a weighting factor to each regulatory category, and sort each regulatory category into a classification; and a calculating module configured to calculate, using at least one computing device, the sustainability indicator for the classification, wherein the calculating module: performs a calculation of an interim sustainability indicator including: determining a percentage of a component in the product, determining whether the component in the product is a member of any regulatory list in a regulatory category in the classification, in response to the component being a member of any regulatory list in the regulatory category in the classification, multiplying the percentage of the component in the product and the weighting factor for the regulatory category in the classification, repeating the calculation of an interim sustainability indicator for each regulatory category in the classification, and combining the interim sustainability indicators for each regulatory category to determine a total sustainability indicator for the component for the classification; repeats the calculation of an interim sustainability indicator for each component in the product to determine a total sustainability indicator for each component for the classification; and combines the total sustainability indicators for each component to determine a total sustainability indicator for the classification for the product.
