NAT.B02 Assessment of dependencies on nature
About the data
Nature’s contributions to people (NCP), or ecosystem services, are the benefits that humans derive from ecosystems and on which human life and activities, including corporate activities, rely. Research shows that more than 50% of global gross domestic product is directly linked to these ecosystem services (WEF and PwC, 2020), with most companies depending on nature, including biodiversity and NCP, as part of their business model. Thus, for companies to understand their relation to biodiversity, it is necessary that they assess not only their impacts but also their dependencies.
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.
Formula
score = (x) -> if x == "Yes" 10 else 0 weights = [0.5, 0.125, 0.125, 0.25] dependencies_on_nature = [dependencies_on_nature, dependencies_on_upstream_value_chain, dependencies_on_downstream_value_chain, dependencies_on_nature_quantification] weights.reduce((weighted_sum, weight, index) -> weighted_sum + weight*score(dependencies_on_nature[index]) , 0)
