The EU and its Member States already account for 80% of external aid provided to Ukraine.

Omissions

• The 80% figure is the EU's own estimate; it aggregates EU institutional aid and bilateral aid from Member States and may include commitments/allocations rather than only disbursed aid.
• Independent trackers such as the Kiel Institute's Ukraine Support Tracker confirm that Europe has overtaken the United States as Ukraine's largest backer, but their 'Europe' aggregate also includes non-EU donors such as the UK and Norway, so the exact 80% EU-only share cannot be independently reconstructed from the snippets available.
• The claim does not specify the reference period or whether the share is based on committed, allocated or disbursed aid.
