Fiscal outlook
Luxembourg recorded a surplus of 0.9% and a debt-to-GDP ratio of 26.3% in 2024. With the nation traditionally sustaining price range surpluses, it slipped right into a deficit of round €1bn on the finish of 2025, through which defence spending greater than tripled.
Deficit measures the extent of borrowing in a given 12 months. Debt-to-GDP compares the whole public debt to the dimensions of the financial system. Each are at the moment used to find out how a lot borrowing a member state is allowed to undertake. Nevertheless, neither measure in itself determines a authorities’s capability to maintain larger ranges of public funding. Fiscal sustainability relies on development, the multiplier results of funding, rates of interest, inflation, the construction of the financial system and exterior dangers similar to local weather change. NEF advocates transferring away from strict numerical debt targets.
Risking local weather prices
Excessive climate occasions like heavy rainfall and storms have turn out to be extra frequent in Luxembourg. The July 2021 floods had been Luxembourg’s most financially expensive catastrophe on report, with damages exceeding €145m and greater than 6,500 houses inundated. Between 1980 and 2023, climatic occasions like heavy rain, storms and floods, precipitated €1.262bn in financial losses in Luxembourg, in keeping with the European Surroundings Company. This ranks Luxembourg second when it comes to financial losses per capita in Europe. The nation’s forests are additionally deteriorating below local weather change, with 4 out of 5 timber broken and one in ten not recovering.
What NEF’s modelling exhibits
Organisation for Financial Co-operation and Improvement (OECD) projections present Luxembourg’s GDP declining by 8% by 2050 and 12% by 2070 below present insurance policies. Our modelling exhibits the next:
- Underneath present insurance policies (BAU – enterprise as traditional), Luxembourg’s debt is projected to be 30 pps larger than the climate-agnostic baseline in 2050 and 119 pps larger in 2070.
- With early EU mitigation and ample adaptation spending, debt is 23 pps larger in 2050 and 42 pps in 2070.
- Delayed EU investments and inadequate adaptation ends in larger debt ranges of 26 pps in 2050 and 53 pps in 2070.
- EU early motion mixed with international cooperation ends in 1 pps decrease debt ranges than the climate-agnostic baseline in 2050 and 14 pps decrease ranges in 2070.
- Progressive taxation similar to a wealth tax mixed with EU early motion would enhance debt by 8 pps in 2050 and by 10 pps in 2070 in comparison with the climate-agnostic baseline.
