%description
Native, deterministic calculations for selected environmental, social and
governance metrics. Provides granular taxonomy criteria, non-financial
taxonomy indicators, principal adverse impact components, portfolio
calculations and configurable performance ratings. Versioned local
resources, explicit assumptions and structured results support
reproducible offline use. Does not determine legal applicability or
provide a complete regulatory reporting system. Selected methods reference
EU Regulations 2020/852, 2022/1288 and 2023/2772; exact editions and
provision locators are supplied in the bundled source contracts. For
background on the taxonomy framework, see the European Commission
<https://finance.ec.europa.eu/sustainable-finance/tools-and-standards/eu-taxonomy-sustainable-activities_en>.
