Water scarcity affects more than 40% of people around the world – an alarming figure that is projected to increase due to climate change (UN, 2021). Water challenges include not only water scarcity but also pollution, flooding and access to drinking water and sanitation services. Companies are expected to adopt water stewardship practices that ensure water use and treatment are socially equitable and environmentally sustainable (UNGC, 2007).
A note on the scoring system
Wikirate uses a standardized 10-point scoring system to enable comparison of company scores across different benchmarks. In the Nature Benchmark, companies can earn 1 point per indicator, which are then added together and calculated as a percentage of the total score for a measurement area (MA) to determine the final score for the MA. The overall Wikirate score is calculated by combining these scores with the appropriate weightings, and converting them to a 10-point scale. For instance, if a company achieves a final score of 50, the corresponding Rating will be 5.
score = (x) -> if x == "Yes" 10 else 0 weights = [0.25, 0.25, 0.25, 0.25] water_n_sanitation = [right_to_water, preventing_risks, requiring_business_partners_to_respect_right, improving_business_partner_practices] weights.reduce((weighted_sum, weight, index) -> weighted_sum + weight*score(water_n_sanitation[index]) , 0)
