Weighting is an additional, but not mandatory, step that may support the interpretation and communication of the results of the analysis. Results of the environmental sustainability assessment are multiplied by a set of weighting factors, which reflect the perceived relative importance of the impact categories considered. Weighted results can be directly compared across impact categories, and also summed across impact categories to obtain a single-value overall impact indicator. Weighting requires making value judgements as to the respective importance of the impact categories considered. These judgements may be based on expert opinion, social science methods, cultural/political viewpoints, or economic considerations.
