About the data
The accidental or voluntary introduction of IAS is one of the most common threats to species as well as a very important factor in ecosystems’ decline and deterioration. IAS can be defined as species introduced into a foreign environment which adversely impact local biodiversity through competition and predation, provoking the disruption of local ecosystems and ecosystem functions. The CBD’s Post-2020 Global Biodiversity Framework requires that the introduction of IAS be managed and the rate of their introduction and establishment be lessened by at least 50% (CBD, 2021).
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 WikiRating will be 5.
