The EU's outermost regions host 80% of all EU biodiversity.

Omissions

• The figure is commonly expressed as 'over 80%' or '80% of European biodiversity', a minor scope variation from the strict 'EU biodiversity' wording used by the MEP.
• No primary official statistical publication (Eurostat, European Commission strategy document) confirming the exact 80% figure could be retrieved within the search budget; the figure circulates as an EU policy/NGO estimate rather than a single audited statistic.
• The figure is an order-of-magnitude policy estimate that has been repeated across EU communications about the outermost regions for years, so its original methodological basis is not traceable to a single dataset.
