My association @global-redistrib.bsky.social wrote a report to find new resources for the EU.

➡️Six new taxes can fund NGEU repayment, a sovereign fund, global public goods, expanded EU budget AND reduced Member States contributions.

(9/9) thanks to Lennart Stern, Arved Döpinghaus, Xuan Xie and @adrien-fabre.bsky.social for this great and interesting project

(8/9) Policy report:

(7/9) New EU own resources could do two things at once: finance European public goods—security, defence, cross-border transport & energy infrastructure, and a resilient low-carbon energy system—while reducing GNI-based national contributions.

@mkalkuhl.bsky.socialOct 6, 2026, 10:43 AM

(6/9) Together, all 6 options could raise roughly €100bn/year. For scale: the EU’s annual budget is around €190bn and is still financed largely through contributions from Member States.

(5/9) The report also includes 4 proposals developed by other authors: 💰 one-off levy on large fortunes: ~€26bn/yr 💻 digital services tax: ~€6bn/yr 📱 digital advertising levy: ~€10bn/yr 📈 financial transaction tax: ~€8.3bn/yr

@mkalkuhl.bsky.socialOct 6, 2026, 10:43 AM

(4/9) Second: reform intra-EU aviation taxes. A tax on vacant seats, paired with VAT reform, could raise ~€10.5bn/year. In the modelled first step, passenger numbers stay unchanged while airlines fly ~18% fewer flights by filling planes more efficiently.

@mkalkuhl.bsky.socialOct 6, 2026, 10:43 AM

(3/9) Our first proposal: a European luxury surcharge. A 20% levy would apply only to the part of the price above category-specific thresholds—for high-end cars, yachts, private jets and other luxury goods. Estimated revenue: ~€42bn/year.

@mkalkuhl.bsky.socialOct 6, 2026, 10:43 AM

(2/9) The core idea: some taxes work better at EU level than nationally. When shoppers or tax bases can move across borders, national taxes can trigger avoidance and tax competition. EU-wide coordination can raise revenue more efficiently and create fiscal space for Member States.

How can the EU finance more common priorities without putting ever more pressure on national budgets? A new Global Citizen report explores 6 options for new EU own resources. We contributed to 2: taxes on luxury consumption and intra-EU aviation. (1/9)

Übrigens: Für einen 2-Personen-Haushalt mit einem PKW wäre die Grenze erst bei 9200 km erreicht, ab der der Tankrabatt vorteilhafter wäre. (2/2)

@mkalkuhl.bsky.socialSep 20, 2026, 10:55 AM

Für den Tankrabatt sind 2,5 Mrd.€ fiskalische Kosten geplant. Eine äquivalente Pro-Kopfzahlung an alle 45,5 Mio Erwerbstätige macht 55€ p.P. Bei weniger als 4600 km Fahrleistung in Okt-Dez ist der Pro-Kopf-Betrag besser. Effizienter ist er sowieso ariadneprojekt.de/publikation/... (1/2)
