About AmendEU

Amendments are where much of Parliament’s real drafting work happens. Before a draft law is voted, Members propose written changes to it in committee — deletions, insertions, rewordings. Each one is published in an official document with its authors listed. That paper trail says, precisely and verifiably, who tried to change what in EU law. AmendEU makes it navigable: 1,259,320 distinct amendments across 5,083 procedures and 2,499 Members, over five parliamentary terms.

1. Parliament publishes. Members table amendments in parliamentary committees; the Parliament publishes each batch as an official document on europarl.europa.eu.
2. Parltrack aggregates. The open-data project Parltrack has been turning those documents into machine-readable records since 2008. Its bulk dataset is the backbone of this site (it stopped updating in early February 2026).
3. We read the most recent documents ourselves. For February–July 2026, the counts are extracted directly from the official amendment documents published by the Parliament. Wherever that recent slice contributes to a number, the page says so explicitly.
4. We count with one simple convention. An amendment is credited to every Member listed as an author — most committee amendments are co-signed by several. A procedure’s total counts each distinct amendment once. Solo means the Member tabled it alone.
5. Votes come from HowTheyVote. Plenary roll-call results shown on procedure and Member pages are from HowTheyVote.eu, which republishes the Parliament’s own voting records.
6. Summaries are grounded, never invented. The plain-language summaries are machine-generated from the amendment texts themselves and quality-checked against them. Where no text is available, the page says “pending” instead of guessing.

• Plenary amendments — those are tabled by political groups, not attributed to individual Members, so they are out of scope.
• Anything outside the coverage window — machine-readable, author-attributed committee amendments begin in 2008; the window is stated on every page footer and never silently extended.
• Judgements. We publish counts and texts, not grades. Rankings by volume exist because they help navigation — but volume measures activity, not influence or quality, and this site draws no conclusion from it.

Coverage: 2008 → ~July 2026 · 5 terms · Jan–Jul 2026 tail from EP official documents. Last refreshed 5 Jul 2026.

AmendEU is updated once a week, every Sunday. Each refresh re-runs the whole pipeline from the sources — pulling any newly published amendments and, during plenary weeks, the latest roll-call votes and the sitting agenda. Counts are exact within the stated window and never estimated.
