A taxonomy is a classification system that employs uniform terms and definitions. The EU has developed such a classification system in the “Environmental” area, for the goals “protect the climate” and “adapt to climate change” (Regulation 2020/853 of June 18, 2020). The taxonomy makes it possible to assess the environmental sustainability of an activity on a comparable basis. The taxonomy definitions are also intended to become the basis for companies’ non-financial reports. In July 2021, a taxonomy proposal was submitted for the “Social” area.
